Abstract
Peer-A (101) broadcasts a Peer Lookup Query (107) to a Peer Discovery Service (PDS) (105). Peer-A (101) may receive a Peer Lookup Response (109) from any peer having the reachability information including a Time Stamp, and an Initial Sequence Number. Peer-A (101) may subsequently use the Time Stamp and Sequence Number to send session management and session media packets to Peer-B (103). Peer-A (101) and Peer-B (103) reciprocally store message identification including sequence number and timestamp in a local session record contained in a secure memory. At completion of the IP session, both Peer-A (101) and Peer-B (103) will dump the session records from their respective secure memories to a remote Session Log Database (115), via message (117) and message (119), respectively. The remote session DB consolidates the records and uses the temporal and causal relationships between the messages to resolve any data conflicts and recreate the complete session record.
