TAILIEUCHUNG - Session Initiation Protocol (SIP)

SIP is a lightweight, transport-independent, text-based protocol. SIP has the following features: Lightweight, in that SIP has only four methods, reducing complexity Transport-independent, because SIP can be used with UDP, TCP, ATM & so on. Text-based, allowing for low overhead SIP is primarily used for VOIP calls | Session Initiation Protocol (SIP) Features of SIP SIP is a lightweight, transport-independent, text-based protocol. SIP has the following features: Lightweight, in that SIP has only four methods, reducing complexity Transport-independent, because SIP can be used with UDP, TCP, ATM & so on. Text-based, allowing for low overhead SIP is primarily used for VOIP calls Functions of SIP Location of an end point Signal of a desire to communicate Negotiation of session parameters to establish the session And teardown of the session once established. How SIP works SIP user agents: like cell phones, PCs etc. They initiate message writing. SIP Registrar servers: They are databases containing User Agent locations; they send agents IP address information to SIP proxy servers. SIP Proxy servers: accepts session request made by UA and queries SIP registrar server to find recipient UA address. SIP Redirect servers: they help communicating outside the domain Continued Continued Our user A tries to
