Webb8 nov. 2016 · Once the session is established, an endpoint can exchange data. DATA chunk exchange in SCTP is similar to TCP’s Selective ACK procedure. Receipt of DATA chunks is acknowledged by sending SACK chunks. In TCP we acknowledge the number of received bytes. In SCTP we use Transmission Sequence Number (TSN) to acknowledge the … WebbSCTP uses a transmission sequence number (TSN) to number the data chunks. TSNs are 32 bits long and randomly initialized between 0 and 232 - 1. Each data chunk must carry the corresponding TSN in its header. Stream Identifier (SI): In TCP, there is only one stream in each connection. In SCTP, there may be several streams in each association.

Webb25 maj 2024 · I did not consider that, as dcSCTP would treat any FORWARD_TSN as deleting the received fragments for the currently received message which included a TSN as provided in the FORWARD-TSN (because that would be the intention by the sender, by sending a FORWARD-TSN). http://www.myreadingroom.co.in/notes-and-studymaterial/68-dcn/855-sctp-features.html

WebbWhen stateful SCTP inspection is enabled, SCTP heartbeat traffic fails by means of the backup path because the primary path goes through a different platform and VDOM. Since there is no state sharing between VDOMs, the passive FortiGate is unaware of the original SCTP session and drops the heartbeats because of no associated sessions.
