Better Networking with SCTP

Posted by ryuzaki0 on from the viva-la-sctp dept.

5-0 writes to tell us that IBM DeveloperWorks has an interesting look at the key features of SCTP in the Linux 2.6 kernel and the ability to deliver multi-streaming. "SCTP is a reliable, general-purpose transport layer protocol for use on IP networks. While the protocol was originally designed for telephony signaling, SCTP provided an added bonus -- it solved some of the limitations of TCP while borrowing beneficial features of UDP. SCTP provides features for high availability, increased reliability, and improved security for socket initiation."

    lets change the quote scope a little:

    SCTP protects against this type of attack through a four-way handshake and the introduction of a cookie. In SCTP, a client initiates a connection with an INIT packet. The server responds with an INIT-ACK, which includes the cookie (a unique context identifying this proposed connection). The client then responds with a COOKIE-ECHO, which contains the cookie sent by the server. At this point, the server allocates the resource for the connection and acknowledges this by sending a COOKIE-ACK to the client.

    Funny how things suddenly makes sense when you read the entire paragraph.
