چکیده

In this paper we compare two approaches for lossbased overload control mechanisms in signaling system with SIP protocol, hop-by-hop and end-to-end. Both discussed mechanisms are based on using a simple non-preemptive priority queueing scheme in SIP server. The effectiveness of both approaches is compared with the system with no overload control. The effectiveness of the solution is measured by average call setup time, goodput and basic fairness. Keywords-component; SIP protocol; signaling system; overload control mechanisms; basic fairness.

ملزومات امنیتی پیاده‌سازی IMS SIP سرور امن

IMS (IP Multimedia Subsystem) network is considered as an NGN (Next Generation Network) core networks by ETSI. Decomposition of IMS core network has resulted in a rapid increase of control and signaling message that makes security a required capability for IMS commercialization. The control messages are transmitted using SIP (Session Initiation Protocol) which is an application layer protocol. ...

SIP Rate

The prevalent use of the Session Initiation Protocol (SIP) in Next Generation Networks necessitates that SIP networks provide adequate control mechanisms to maintain transaction throughput by preventing congestion collapse during traffic overloads. A loss-based solution to remedy known vulnerabilities of the SIP 503 (Service Unavailable) overload control mechanism has already been proposed. Usi...

Analysis and Modeling of VoIP Servers: A Linear Programming Approach

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...
