Summary:
|
Multi-stream data transmission over parallel channels is one of the well-known options for reducing network delay by increasing the total bandwidth of the connection between the nodes exchanging data. This method is used in particular in the SCTP protocol, a well-known disadvantage of which is its limited support by network equipment, both terminal and routing.
That is why many modern protocols of the transport and session layers of the OSI model are developed as extensions of the TCP protocol or work on top of the UDP protocol, implementing flow control mechanisms and reliable data delivery.
There are several examples of multistream protocols based on traditional transport protocols. The Multipath TCP (MPTCP) was produced by the Internet Engineering Task Force (IETF) and described in RFC 8684 [b-rfc8684]. Korean researchers proposed the Dynamic Multi-stream Transport Protocol over TCP [b-seok]. Also there is a modification of protocol SCTP over UDP suggested by Indian researchers [b-belkhode].
Combining multistream data transmission with the principles of network coding allows, in addition to increasing the throughput, to increase the security of the transmitted user data, since the data in this case is transmitted not in clear form, but in the form of linear combinations of data blocks, which complicates their interception by a third party, requiring the interception of all blocks of data to restore the original information.
These aspects are considered in this Recommendation. This Recommendation include:
Principle of multistream transmission with network coding.
Protocol placement in the TCP/IP stack.
Protocol logic.
Packet structure.
