Abstract:
1. A system for a network signaling protocol bypass around a cryptographic device, comprising: a first bypass device configured for parsing a GIST signaling transport protocol identifier from a transport layer protocol header of a packet, communicating said packet to a second bypass device if said GIST signaling transport protocol identifier is a NTLP or a NSIS signaling transport protocol identifier, and communicating said packet to said cryptographic device if said GIST signaling transport protocol identifier is not a NTLP or a NSIS signaling transport protocol identifier, and wherein said second bypass device is configured for parsing a NSLP protocol identifier from a NSLP layer protocol header of said packet, determining whether said NSLP protocol identifier is equal to at least one predetermined NSLP protocol identifier, communicating said packet to said cryptographic device if said NSLP protocol identifier is equal to said at least one predetermined NSLP protocol identifier, and bypassing said packet around said cryptographic device if said NSLP protocol identifier is not equal to said least one predetermined NSLP protocol identifier, wherein said parsing and said determining at said second bypass device is based exclusively on said NSLP protocol identifier.
