How the data chunks are identified in sctp
The Stream Control Transmission Protocol (SCTP) has a simpler basic packet structure than TCP. Each consists of two basic sections: 1. The common header, which occupies the first 12 bytes. In the adjacent diagram, this header is highlighted in blue. 2. The data chunks, which form the remaining portion of the packet. In the diagram, the first chunk is highlighted in green and the last of N chunks (Chunk N) is highlighte… Nettet11. apr. 2024 · The E2 interface protocol stack is built on top of the IP layer. An application protocol called E2AP is specified by O-RAN Alliance over SCTP/IP as the transport protocol. On top of E2AP, application-specific controls and events are conveyed through E2 service models (E2SM). The xApps in the Near-RT RIC use the E2SMs.

NettetS-SCTP provides data integrity and origin authentication not only for the user data transported by SCTP, but also for the peer-to-peer control information used by SCTP … NettetIt describes the Stream Control Transmission Protocol (SCTP). SCTP is designed to transport Public Switched Telephone Network (PSTN) signaling messages over IP networks, but is capable of broader applications. SCTP is a reliable transport protocol operating on top of a connectionless packet network such as IP.

In SCTP, user messages are contained in a data chunk whereas a control chunk consists of a protocol message, see Figure 4.
