  • Load balancing SCTP associations using VTAG mediation
    Patent number: 8737210
    Abstract: Presented is a system and methods for routing Stream Control Transmission Protocol (SCTP) between a client and a back-end server by a front-end server operating transparently between the client and the back-end server. The front-end server uses a distribution key created by the front-end server to route the SCTP packets to the proper destination. The distribution key is comprised of a client SCTP port number, a back-end server SCTP port number and a back-end server Initiate-Tag. The front-end server arbitrates clashes between distribution keys of different back-end servers by replacing the back-end server generated SCTP Initiate-Tag with a front-end server generated SCTP Initiate-Tag.

  • SCTP ASSOCIATION ENDPOINT RELOCATION IN A LOAD BALANCING SYSTEM
    Publication number: 20120233240
    Abstract: Presented is a system and methods for relocating a Stream Control Transmission Protocol (SCTP) association from a first back-end server to a second back-end server without disturbing the SCTP association connection. The front-end server coordinates the replacement by requesting SCTP association connection parameters from the first back-end server and providing the SCTP association connection parameters to the second back-end server. Further, the front-end server discards any SCTP association packets, not necessary to the replacement, directed to the two back-end servers during the replacement. Throughout the replacement, the client, on the non-relocating end of the SCTP association, is unaware of the replacement or the existence of the front-end server.
