sctp user initiated abort

sctp user initiated abort

The value of 255 is * reserved for future use as an extension field. * Note that the descriptions from the specification are USER level * functions--this file is the functions which populate the struct proto * for SCTP which is the BOTTOM of the sockets interface. sctp_connectx (3) - initiate a connection on an SCTP socket using multiple sctp_getladdrs (3) - Returns all locally bound addresses on a socket. However, in the FreeBSD implementation, we send it, if the ABORT is initiated by the user. The endpoint remains in this state until it sends all pending DATA chunks (accepted before the shutdown initiation). sctp_send (3) - Send a message from a SCTP socket. Stream Control Transmission Protocol (SCTP), the services it offers, and the basic concepts needed to understand the detailed description: of the protocol. Updates: RFC 2960. SCTP_STATUS Applications can retrieve current status information about an association, including association state, peer receiver window size, number of unacked data chunks, and number of data chunks pending receipt.

SCTP (Stream Control Transmission Protocol) is a protocol for transmitting multiple streams of data at the same time between two end points that have established a connection in a network. For example, if the DATA chunk has to contain a given value in network byte order, the SCTP user has to perform the htonl(3SOCKET) computation. class ryu.lib.packet.sctp.cause_user_initiated_abort (value=None, length=0) ¶ Stream Control Transmission Protocol (SCTP) sub encoder/decoder class for User-Initiated Abort (RFC 4960).
