Hello Ambika The In-bound stream and Out-bound streams parameters of INIT and INIT ACK chunk tells the peer that how many maximum IBS and OBS the sender can support. Based on this received stream information from peer and it's own configuration the stack decides the final stream configuration. The number of final Inbound stream = MIN(Own IBS, Peer's OBS) The number of final Outbound stream = MIN(Own OBS, Peer's IBS) In your example ASP SG --------------INIT[IBS=5, OBS=5]-----------------> <---------INIT ACK [IBS=2, OBS=2]------------- After receiving INI-ACK at ASP: Inbound stream = MIN(5,2) = 2 Outbound stream = MIN(5,2) = 2 Ashwani Kathuria A R I C E N T The Presidency Tower ?A, 351/2, Sector 14 M.G.

If I am not wrong below is the result. INIT OBS = 5 IBS = 5 INIT-ACK OBS = 2 IBS = 2 and the ASP end after receiving the INIT-ACK what should be updated OBS and IBS. -- Br, Ambika Prasad Tripathy Nethawk Networks Cell: +91-94375 47730 _______________________________________________ Sigtran mailing list [email protected] https://www1.ietf.org/mailman/listinfo/sigtran *********************** Aricent- Confidential *********************** *********************** Aricent- Confidential *********************** "DISCLAIMER: This message is proprietary to Aricent and is intended solely for the use of the individual to whom it is addressed.
