  • Network interface redundancy
    Patent number: 6678369
    Abstract: A signal system 7 (SS7) processing system for use in an SS7 network includes a primary interface configured to process communications according to at least one layer of the SS7 protocol stack, the primary interface being configured to provide checkpoint messages relating to the communications and the at least one layer of the SS7 protocol stack, each layer of the at least one layer of the SS7 protocol stack having a corresponding set of information associated with each communication, and a backup interface configured to process communications according to the at least one layer of the SS7 protocol stack, the backup interface being coupled to the primary interface, and configured, to receive the checkpoint messages from the primary interface, wherein the checkpoint messages contain sufficient information for the backup interface to properly process communications that are transferred from being processed by the primary interface to being processed by the backup interface and contain less than all information i
