Routing service

The Routing Service is a generic SOAP broker that acts as a message router. The main functionality of the routing service is the ability to route messages according to their content, which allows a message to be forwarded to a client connection point based on a value within the message itself, in the message header or body.

The services router is implemented as a Windows Communication Foundation (WCF) service in the System.ServiceModel.Routing namespace. The routing service exposes one or more service ends that receive messages and then routes each message to one or more client ends depending on the content of the message. The service provides the following features:

·         Content based routing

o    Service aggregation

o    Service version control

o    Priority Routing

o    Dynamic configuration

·         Protocol bridge

·         SOAP processing

·         Advanced Error Control

·         backup connection points

Although it is possible to create an intermediate service that achieves one or more of these objectives, this type of implementation is often linked to a specific solution or scenario and cannot be applied directly to new applications.

The routing service provides a generic, dynamically configurable and connectable SOAP broker that is compatible with WCF channel and service models and allows you to perform content-based routing of SOAP-based messages.

Content based routing

Content-based routing is the ability to route a message based on one or more values contained within the message. The routing service inspects each message and routes it to the destination connection point based on the content of the message and the routing logic created. Content-based routing provides a basis for service aggregation, service version control and priority routing.

To implement content-based routing, the routing service relies on the MessageFilter implementations that are used to match specific values within the messages to be routed. If a MessageFilter matches a message, the message is routed to the destination endpoint associated with the MessageFilter . Message filters are grouped together in filter tables ( FilterTableCollection ) to build complex routing logic. For example, a filter table could contain five filters of mutually exclusive messages that cause messages to be routed to only one of the five destination connection points.

The routing service allows you to configure the logic used to perform content-based routing, as well as dynamically update the routing logic at runtime.

Through the grouping of message filters into filter tables, a routing logic can be created that allows you to manage various routing scenarios, such as:

Service aggregation

Service version control

Priority Routing

Dynamic configuration

For more information about message filters and filter tables, see Introduction routing and message filters .

Service aggregation

Using content-based routing, you can expose a connection point that receives messages from external client applications, and then routes each message to the appropriate internal connection point based on a message value. This is useful for providing a specific connection point for various back-end applications and also presenting an application connection point to customers while factoring their application into various services.

Service version control

When you migrate to a new version of the solution, you may have to keep the old version in parallel to serve existing customers. Often, this requires that clients connecting to the latest version use a different address when communicating with the solution. The routing service allows you to expose a service connection point that serves both versions of the solution by routing the messages to the appropriate solution based on the specific information of the version contained in the message. For an example of this type of implementation, see How To: Service Version .

Priority Routing

By providing a service for several customers, you can have a service level contract with some partners that requires that all data from these partners be processed separately from that of other customers. Using a filter that searches for specific customer information included in the message, you can easily route messages from specific partners to a connection point created to meet the requirements of your service level contract.

Dynamic configuration

To support vital systems for a mission, where messages must be processed without any service interruption, it is vital that you can modify the configuration of components within the system during runtime. To enable this need, the routing service provides an IExtension <T> implementation , RoutingExtension , which allows you to perform a dynamic update of the routing service configuration during runtime.

For more information about the dynamic configuration of the routing service, see Introduction routing .

Protocol bridge

One of the challenges in intermediate scenarios is that internal endpoints may have different SOAP or transport version requirements than the endpoint at which messages are received. To support this scenario, the routing service can shorten the protocols, including the processing of the SOAP message to MessageVersion required by the destination endpoints. In this way, one protocol can be used for internal communication, while the other is used for external communication.

To support the routing of messages between endpoints with different transports, the routing service uses links provided by the system that allow the service to shorten protocols that are not equal. This occurs automatically when the service connection point exposed by the routing service uses a different protocol than that of the client connection points to which messages are routed.

SOAP processing

A common routing requirement is the ability to route messages between endpoints with different SOAP requirements. To support this requirement, the routing service provides a SoapProcessingBehavior that automatically creates a new MessageVersion that meets the requirements of the destination connection point before the message is routed to it. This behavior also creates a new MessageVersion for any response message before returning it to the requesting client application, to ensure that the MessageVersion of the response matches that of the original request.

For more information about SOAP processing, see Introduction routing .

Error control

In a system composed of distributed services that rely on network communications, it is important to ensure that communications within the system are resistant to transient network errors. The routing service implements an error control that allows you to manage many cases of communication failures that might otherwise cause a disruption of the service provision.

If the routing service finds a CommunicationException class while trying to send a message, error handling will be activated. These exceptions usually indicate that a problem was encountered while trying to establish communication with the defined client endpoint, such as EndpointNotFoundException , ServerTooBusyException or CommunicationObjectFaultedException . The error control code will also detect and attempt to re-send when a TimeoutException occurs, which is another common type of exception that CommunicationException is not derived .

For more information about error control, see Introduction routing .

backup connection points

In addition to the destination client endpoints associated with each filter definition in the filter table, you can also create a list of reserve endpoints to which the message will be routed in the event of a transmission error. If an error occurs and a reserve list is defined for the filter entry, the routing service will attempt to send the message to the first end defined in the list. If this transmission attempt is not successful, the service will test the next connection point, and continue this process until the transmission attempt is correct, return an error not related to the transmission or all connection points in the list reserve have returned a transmission error.

For more information about backup endpoints, see Introduction routing and message filters .

Streaming

The routing service can transmit messages correctly if you establish the link to support streaming. However, there are some conditions under which it is necessary to buffer messages:

Multicast (use the buffer to create additional copies of the messages)

Failover (use the buffer in case it is necessary to send the message to a reservation)

System.ServiceModel.Routing.RoutingConfiguration.RouteOnHeadersOnly is false (use the buffer to present MessageFilterTable with a MessageBuffer so that filters can inspect the body)

support abilities

Support professionals ought to guarantee that the hardware utilized in the assembling and handling businesses works appropriately and productively. Analyze and fix issues. They additionally perform intermittent upkeep checks.

Upkeep professional work exercises

At the point when an assembling part or apparatus or preparing hardware isn't working appropriately, it must be fixed. They study the specialized plans of the apparatus to investigate the issue, or adhere to the directions composed on a guidance sheet.

They recognize the establishment or hardware blunder and fix it with hand instruments, for example, keys, keys and screwdrivers. They additionally use power devices and perform welding to finish the fix support aptitudes pc maintenance. 

At times, they supplant worn parts, at that point oil them with oil and modify hardware or gear before reassembly.

Upkeep professionals must be specialists in a wide range of zones. For instance, they can work with electronic, pneumatic and water driven gear.

At times support professionals need to totally check the hardware. They are liable for the extraction of apparatus, control and cleaning of its parts and afterward reassemble them.

They reestablish gear and apparatus intermittently, for instance, when a year, when the industrial facility or plant is shut for summer excursions.

Upkeep specialists now and again put in new hardware and can help train administrators on the best way to utilize them.

The work can be filthy or grimy. Support experts can wear overalls or defensive outfits, security glasses and defensive footwear.

Upkeep specialists regularly work in a contiguous workshop or region away from the fundamental assembling or preparing plant. Sometimes, they work outside, for instance, at the establishment site of the gear.

Maintenance work on the server

Disconnect the Direct Storage Spaces server for maintenance work

This topic provides instructions for restarting or shutting down servers correctly with Direct Storage Spaces .

If you use Direct Storage Spaces to disable a server (turn it off), keep in mind that parts of the storage that have been shared on all servers in the cluster will also be disabled. For this, you must pause (suspend) the server you want to disconnect, move the roles to other servers in the cluster and verify that all data is available on the other servers in the cluster; Thanks to this, the data will remain secure and you can access it during the maintenance task.

Follow the steps below to successfully pause a server in a Direct Storage Spaces cluster before deactivating it.

Check that it is safe to disconnect the server

Before disconnecting the server to perform maintenance work, check that all volumes are in good condition server maintenance job.

To do this, open a PowerShell session with administrator permissions and run the following command to see the status of the volumes:Verify that the HealthStatus property of all volume (virtual disk) is Correct .

To do this in the Failover Cluster Administrator, go to Storage > Disks .

Check that the Status column of each volume (virtual disk) is displayed Online .

Pause and purge the server

Before restarting or shutting down the server, pause and purge (remove) any type of role, such as virtual machines running on the server. Thanks to this, Direct Storage Spaces will be able to empty and confirm the data correctly, in order to ensure that the shutdown is carried out without mishaps taking into account the applications running on that server.

In PowerShell, run the following cmdlet (as administrator) to pause and purge.

To do this in the Failover Cluster Administrator, go to Nodes , right-click on the node, and then select Pause > Purge Roles

Turn off the server

Once the server is purged, it will show Paused in PowerShell and in Failover Cluster Administrator.You can now restart it or shut it down safely, just as you normally would (for example, using the Restart-Computer or Stop-Computer PowerShell cmdlets).

The incomplete or degraded operating state is normal when the nodes are closing or starting or stopping the cluster service on a node and should not be a problem. All volumes remain online and are accessible.

What is Wifi?

In computing , it is known as Wifi (derived from the Wi-Fi brand) to a telecommunications technology that allows wireless interconnection between computer and electronic systems , such as computers, video game consoles, televisions, cell phones, players, pointers, etc. .

This technology allows these devices to connect with each other to exchange data , or connect to a wireless network access point, thus being able to have an Internet connection.

And although the Wi-Fi brand identifies a corporation that certifies the necessary standards of technology that has this connection capability, the term Wifi is commonly used to refer to the latter and not to the company wifi connect.

Wifi emerged as a response to the need for standardization and compatibility in the wireless connection models of the various digital devices, also overcoming other unsupported forms of connection such as Bluetooth, GPRS, UMTS, etc. Unlike these, Wifi  uses radio waves as a vehicle for transmitting information .

This technology is designed to connect devices over relatively short distances (100 meters maximum), especially in environments that offer a lot of interference or noise to the signal, such as that produced by the saturation of the radio spectrum due to multiplicity of emissions. In addition, it is a slower connection than the wired one , but significantly more comfortable and versatile.

The other disadvantage of connections of this type has to do with security, since any device that picks up the signal is likely to have access to the sending point . This is usually configured through passwords and other security mechanisms, but the possibility of a cyber violation is always latent.

Wifi types

Various types of Wifi are known, according to the standards they use for their identification and which can be distinguished into two categories:

• 2.4 GHz band . Here are the IEEE 802.11b, IEEE 802.11ge and IEEE 802.11n standards, whose handling is international and allows speeds of 11 Mbit / s, 54 Mbit / s and 300 Mbit / s respectively. However, it is the type that has the greatest interference, since the 2.4 GHz band is also used by Bluetooth and other wireless systems.
• 5GHz band . The new type of Wifi, known as WIFI 5, applies the IEEE 802.11ac standard and is handled in a completely new and interference-free channel, so, despite being a recent technology and having a 10% disadvantage less than range, it is considered extremely convenient given its stability and speed.

Wifi operates very similarly to cell phones or radio transmitters. Initially, the data of an Ethernet connection is decrypted by an ordinary modem , which transmits its decoded signal to a wireless router or  router , which transmits it in the form of radio waves around it. In many cases both devices already consist of only one, which fulfills both functions: it receives the broadband signal and interprets it as radio waves.

Then, the Wifi device on our computer or cell phone, to name an example, interprets these radio signals and converts them into information again. The cycle is then repeated when our device sends instead of receiving information, and so on and simultaneously

how do wireless signals work

how remote innovation functions 

The remote innovation has consistently been gone before by wired innovation and is commonly progressively costly, yet has given the additional bit of leeway of portability, permitting the client to get and transmit data while moving how do wireless signals work. 

Another significant increase in remote innovation has been in the territory of ​​broadcasting interchanges, for example, radio, TV and direct transmission satellite. A solitary remote transmitter can impart signs to a few hundred thousand collectors as long as everybody gets a similar data. 

Today, remote innovation includes specialized gadgets as differing as carport entryway openers, child screens, walkie-talkies and Smartphone , just as transmission frameworks, for example, highlight point microwave joins, remote Internet administration and satellite correspondences. 

Remote chargers are another kind of remote gadget. Albeit no information is sent through a remote charger, it interacts with another gadget, (for example, a telephone) without utilizing links. 

How does remote innovation work? 

Remote innovation works on the grounds that an electromagnetic wave , which goes through the air at the speed of light, can make, or "prompt," an electrical sign on a recieving wire. On the off chance that we can control this electromagnetic wave, at that point we can utilize it to impart or to transmit data starting with one spot then onto the next are need of links. 

The data is sent from one spot, the transmitter , and is gathered in another, the recipient , utilizing an electromagnetic wave to ship it. The transmitters and recipients are situated at each finish of the remote framework , utilizing a recieving wire at each end. 

In any case, to comprehend remote innovation it is first important to know the electromagnetic waves. Electromagnetic waves are typically sinusoidal. The recurrence of an electromagnetic wave is the speed at which the sign vibrates. In particular, the recurrence of a wave is the occasions the wave is rehashed in a second , and is communicated in Hertz. A 1Htz wave is rehashed once consistently. Would you be able to envision to pay tribute to who put the Hertz unit, NO? For instance, FM radio signs vibrate around 100 million times each second. 

Another significant actuality is the wavelength , which is the separation between 2 peaks of a wave. Sensibly, the more extended the wavelength, the lower the vibration recurrence.. On the off chance that it vibrates quick (regularly) the created waves will be nearer to one another and will have shorter wavelengths. 

Presently we can order the electromagnetic waves as indicated by their recurrence or wavelength , and utilize some for one sort of transmission and others for an alternate kind, right now can send various kinds of data without meddling with certain waves with others. 

On account of the various frequencies ( electromagnetic groups ) that an electromagnetic wave can have we can produce two distinct signals at the same time without their signs meddling with one another. We consider the range or scope of various frequencies an electromagnetic range. The Governments of every Country are liable for doling out recurrence ranges for every particular reason. 

Authorized groups are claimed by specific organizations or offices for explicit purposes and can't be utilized by any other individual. Groups without a permit are free and anybody can utilize them, subject to specific principles. Authorized groups are commonly liberated from impedance and are progressively dependable, since there is power over who can transmit them.

types of wireless devices

   “Wireless Nic (Network Card)”

It is a peripheral that allows communication with devices connected to each other and also allows sharing resources between two or more computers.Network cards are also called NICs (by network interface card; in Spanish "network interface card"). There are different types of adapters depending on the type of wiring or architecture used in the network but currently the most common is the Ethernet type using an RJ-45 interface or connector.

A wireless network card is a card for capacity expansion that is used to send and receive data without the need for cables in wireless local area networks ("W-LAN" Wireless Local Area Network "), this is between wireless networks Computers The network card is inserted into the expansion slots or "Slots" integrated in the main board ("Motherboard") and screwed to the cabinet to prevent movement and therefore failures. All wireless network cards integrate an antenna of reception for the signals.

Types of wireless networks

We can distinguish several types of wireless networks. Although in practice we do not notice the difference, each of them has its own peculiarities.

The WAN networks are characterized by being able to cover large areas. Therefore, institutions such as universities or governments use them to create a unique network. Several distant points can be connected via satellites or antennas. The advantage of these is above all economic, since a network can be created quickly through terrestrial bases that act as a repeater and receiver.

WLAN networks , which we talked about recently , are probably the best known. These networks allow you to connect several computers in a nearby location. With it you can share devices such as printers, as well as files and other resources. This type of network uses radio signals between 11 and 54 Mbps. These are the networks used in mobile units, libraries and installations of this type.

On the other hand are wireless PAN networks or personal networks. These communicate equipment a few meters from each other. Examples of these types of networks are the Bluethoot or home automation facilities . All computers and mobiles can be connected inside a home, using only a single transmitte
