Network Coding Datagram Protocol for TCP/IP Networks

In this article, a new multicast protocol is introduced at the session layer, which is based on network coding and is called the Network Coding Datagram Protocol (NCDP). The NCDP protocol is specifically designed for content delivery systems that utilize multicast data transmission from multiple sources. The development of the NCDP packet and its operational logic takes into consideration the variability of the protocols used in conjunction with it, as well as the packet header processing algorithms for routing nodes-coders. Additionally, a virtual laboratory bench is proposed to facilitate research on the operation of the protocol. The article also includes the results of testing the NCDP protocol in networks with butterfly and diamond topologies, with a comparison between simple sequential multicast transmission and network coding transmission.
