What is a Virtual Channel?

A virtual channel refers to a logical communication pathway to permit the transfer of multiple data streaming on a single physical link simultaneously without any delay or disruption. The virtual channel creates a way for the network devices to build and maintain the connections between them without being affected by any issues arising from the underlying physical medium or topology....

Difference between Virtual Path and Virtual Channel

...

Key Terminology

Physical Link: Physical medium or link are the medium through which data are being transmitted between the network devices such as copper wire or fiber optic cable. Logical Link: Logical Link is the virtual path or channel existing between the software and mainly controls the communication relationship between the devices. Network Devices: Routers, switches, bridges, and other hardware components are under network devices and helps for making the communication seamless and efficiently within a network. Data Streams: Data streams are the data packet sequences and are transmitted over a network, along with the source and destination addresses information as to process and deliver to correct location. Virtual Circuit (VC): Virtual Circuit is a logical connection created over the virtual channel to provide a guaranteed bandwidth and quality of service (QoS) over the network for seamless communication and efficient transmission. Label Switching: Label switching is a technique used for data packet forwarding over the virtual channels and unique labels are assigned to each VC packets and are forwarded to their destination based on the assigned labels. Error Correction: Error correction are the techniques used for detection and correcting the errors occurred during the data transmission to ensure a reliable and effective communication....

Examples of Virtual Channel

Let us consider, A network consisting of four devices namely A, B, C, and D and are connected by two links for example Link 1 and Link 2. Let’s assume that, each link has the capacity of 100 Mbps . Suppose, The Device A have to send some data to Device D and both the devices are connected to Link 1. A virtual channel can be created over Link 1 to establish the data transfer between Device A and D and is created mainly with the aim for not to create any interference or disturbance to the other devices communication on the network....

Virtual channel with Different Scenarios

Between End users: Virtual channel can be created between end users and are used for transmitting the end-to-end user data and to control the signaling capacity between the end users, as for seamless and effective data transmission Between an end user and a network entity: Virtual channel can also be used between the user-to-network and to control signaling capacity for smooth functioning and are mainly used for aggregation of traffic from an end user to a network exchange or a network server. Between two network entities: Virtual channel can also be used for network traffic management and routing functions.For example: A network-to-network VPC are used for determining a common route to carry out the network management information....

Conclusion

Virtual channels play a crucial role in modern computer networks systems and can provide an efficient and flexible way to deal with the traffic flow. Virtual channel enables the transmission of multiple data streams over a single physical medium or link and also maximizes the network throughput and reduces the latency as well. Virtual channels also includes the error correction mechanisms for ensuring a reliable and effective communication and hence, virtual channel are now a days considered as an essential component for any robust and reliable networking infrastructure and services....
