Patterns for VoIP Signaling Protocol Architectures
نویسندگان
چکیده
Voice over IP (VoIP) is an alternative to traditional circuit-switched telephony that allows human voice and video to travel over existing packet data networks along with traditional data packets. H.323 and SIP are the two standard protocols used today for signaling and call control in VoIP, and they are essential for providing total access and for supporting IP-based services. In order to provide complete end-to-end connectivity, interworking between SIP and H.323 is necessary since both of these protocols have been extensively deployed. We present here a pattern for the H.323 protocol architecture followed by a Hybrid VoIP signaling protocol pattern that combines H.323 and SIP architectures. These patterns can be used to guide the design of VoIP systems and products as well as to simulate these systems.

The SIP protocol was standardized by the IETF at the application layer for initiating, managing, and terminating multimedia sessions and has been widely used as the main signaling protocol on both the Internet and VoIP networks. Most challenges in this protocol are overload and lack of proper state distribution. These challenges cause a wide range of next-generation network users to face a shar...
