Session Initiation Protocol, SIP, provides controlplane signaling for the IP networks. SIP enables initiating, modifying and terminating sessions for a user, while maintaining neutrality to physical media capabilities and using other protocols to negotiate these. SIP assumes that the transport layer is inherently unreliable and as such provides transport layer mechanisms. For target device disc...

The Session Initiation Protocol (SIP) is a multimedia signalling protocol that has evolved into a widely adopted communication standard. The integration of SIP into existing IP networks has fostered IP networks becoming a convergence platform for both realtime and non-real-time multimedia communications. This converged platform integrates data, voice, video, presence, messaging, and conference ...

BACKGROUND Shc and Grb2 form a complex in cells in response to growth factor stimulation and link tyrosine kinases to Ras during the resulting signaling process. Shc and Grb2 each contain domains that mediate interactions with other unidentified intracellular proteins. For example, the Shc PTB domain binds to 130 kDa and 145 kDa tyrosine-phosphorylated proteins in response to stimulation of cel...

Voice over IP (VoIP) is gaining more popularity in today's communications. The Session Initiation Protocol (SIP) is becoming one of the dominant VoIP signalling protocol[1, 2], however it is vulnerable to many kinds of attacks. Among these attacks, flood-based denial of service attacks have been identified as the major threat to SIP. Even though a great deal of research has been carried out to ...

SIP (The Session Initiation Protocol) is widely used as the signaling protocol for various services in the omnipresent environment. SIP is textual based protocol so the ability to process SIP messages quickly is critical for the performance of consumer electronic devices, such as SIP phone and the various Gateway. Our work enables homogeneous communication between heterogeneous distributed devi...

The Session Initiation Protocol (SIP) is an application-layer control protocol standardized by the IETF for creating, modifying and terminating multimedia sessions. With the increasing use of SIP in large deployments, the current SIP design cannot handle overload effectively, which may cause SIP networks to suffer from congestion collapse under heavy offered load. This paper introduces a distri...
