Patent ID: 7680115

Claim:
A system for a network signaling protocol bypass around a cryptographic device, said system communicatively coupled between an ingress end user node and an egress end user node, said system comprising: a bypass device configured for (a) receiving, by said bypass device, a packet having a transport layer protocol header from said ingress end user node, (b) determining a type of a transport layer protocol used to transport said packet, (c) parsing a signaling transport protocol identifier for a signaling transport protocol from said packet based on said type of said transport layer protocol, (d) determining whether said signaling transport protocol identifier is a Next Step In Signaling (NSIS) Transport Level Protocol (NTLP) or an NSIS signaling transport protocol identifier, and (e) bypassing said packet around said cryptographic device if said signaling transport protocol identifier is determined to be an NTLP or an NSIS signaling transport protocol identifier.
