Methods and apparatus for assigning same sequence number to multiple GTP messages

摘要

A method and apparatus for assigning the same sequence number (“SN”) to multiple messages using a global index pool and non-standard source ports (“NSPs”) are disclosed. After generating a global index pool containing multiple indexes, the process, in one embodiment, generates a set of NSPs for a network device. Upon creating a first SN for a general packet radio service tunneling protocol (“GTP”) message between peer-to-peer communications, the SN is stored in a first field of a first index. The process subsequently inserts a socket address used for indexing or addressing one of the NSPs in a second field of the first index.

1. A method for providing sequence numbers, comprising:
generating a global index pool containing a plurality of indexes, wherein generating a global index pool further includes configuring each index to a 19-bit wide index in the global index pool and providing the global index pool containing equal to or greater than 500,000 indexes; generating a plurality of non-standard ports for a network device, wherein generating a plurality of non-standard ports includes providing eight (8) non-standard ports for a gateway GPRS support node (“GGSN”); providing a first sequence number (“SN”) for a general packet radio service tunneling protocol (“GTP”) message which is used for communication between peers, wherein providing a first SN further includes providing a 16-bit SN for the GTP message which can be sent from the GGSN to a serving GPRS support node (“SGSN”); storing the first SN in a first field of a first index of the plurality of indexes, wherein storing the first SN includes inserting a 16-bit SN in upper portion of a 19-bit index and a 3-bit first socket address in lower portion of the 19-bit index; and inserting a first socket address of the plurality of non-standard ports in a second field of the first index of the plurality of indexes.
