SCTP optimization for carriers (packet drop and stability)

Stream Control Transmission Protocol (SCTP) is used in carrier networks for the transport of telephony (Signaling System 7) protocols over IP, with the goal of duplicating some of the reliability attributes of the SS7 signaling network in IP. 

SCTP optimization is done to: 

•  Avoid the multithread infrastructure problems, when the traffic is high 
•  Improve the SCTP association searching rate (association lookup process speed is inc-reased) by SCTP hash table optimization on the SPU 
•  Improve FSM for retransmission cases
