Summary:
|
The multicast data transmission finds wide application in the modern telecommunication networks, for example, for the network management and control as well as for the different network applications. The number of network services users increase significantly, as well as the number of services, resulting in tremendous network traffic growth. This in turn leads to the network latency increase, that could be inappropriate for some novel network services.
Therefore, one of the purposes of the emerging network protocols consists in the reduction of the network traffic volume without reduction of the number of network services and their functionality. Among the other technologies, network coding can solve this problem with a simple modulo 2 addition and decrease the number of packets transmitted through the network.
It is also important to make such protocols as easy as possible from the viewpoint of the implementation and testing. For this reason, network coding protocol looks more convenient if it is implemented as a session-layer protocol according to the OSI model. In this case network coding functions are performed between the standard TCP/IP stack of protocols and application-layer protocols.
Both these aspects are considered in this Technical Report. This Technical Report include:
Place of the protocol in the OSI model.
Description of different network architectures where network coding protocol is applicable and details of implementation.
Coding and decoding procedures.
Packet types and formats.
Signalling procedures and diagrams.
