The extent and diversity of systems, provided by IP networks, have made various technologies approach integrating different types of access networks and convert to the next generation network (NGN). The session initiation protocol (SIP) with respect to facilities such as being in text form, end-to-end connection, independence from the type of transmitted data, and support various forms of transmission, is an appropriate choice for signalling protocol in order to make connection between two IP…

Signaling Packet Aggregation and Compression in SIP Network: Modeling and Performance Evaluation

A queueing model is developed to describe the process of packet aggregation and compression at the edge proxy, and the steady-state probability distribution of the queue length is derived and the average packet transmission delay is obtained.

Comparison of LBOC and RBOC Mechanisms for SIP Server Overload Control

The comparison of results showed that RBOC mechanism based on the hysteresis control over incoming stream of signaling messages demonstrates higher effectiveness of the congestion control, as a result of which the average time in the overload mode is less than for LBOC mechanism.

It is found that performing overload control locally at a server provides a simple remedy for light cases of overload; however, it is ineffective in handling higher amounts of load.

Overload Control in SIP Networks: A Heuristic Approach Based on Mathematical Optimization

This paper proves that the problem of overload control in SIP network with a set of n servers and limited resources is in the form of NP-hard, and proposes a Load-Balanced Call Admission Controller (LB-CAC), based on a heuristic mathematical model to determine an optimal resource allocation in such a way that maximizes call admission rates regarding the limited resources of the SIP servers.

The paper proposes an overload control for a SIP signaling network to protect from a performance degradation and shows the proposed overload control works well.

On TCP-based SIP server overload control

The traditional notion of TCP flow control alone is incapable of managing overload for time-critical session-based applications, which would be applicable not only to SIP, but also to a wide range of other common applications such as database servers.

Local SIP Overload Control: Controller Design and Optimization by Extremum Seeking

An overload control system for regulating both the queue length and the CPU load of the SIP server and results show that the proposed control system counteracts overload situations and provides a goodput close to the optimal while maintaining low call establishment delays and retransmission ratios.

Reducing session establishment delay using timed out packets in SIP signaling network

This paper studies the SIP system behavior by separating signaling traffic in two different classes Invites and Non-invites and creating a cut-off priority queueing model and demonstrates that the server utilization factor of an overloaded server always remains less than one and hence avoids system collapse.

Session Initiation Protocol (SIP) Server Overload Control: Design and Evaluation

The introduction of a new double-feed SIP overload control architecture with two categories of fairness requirements, namely, user-centric and provider-centric fairness, is introduced and it is shown how the algorithms can meet those fairness criteria.

This study is on the performance of SIP signaling network using UDP and TCP, and implemented new agents that act as SIP elements in the ns-2 and a significant performance difference was found to exist.

Flow Management with Service Differentiation for SIP Application Servers

Intensive experiments show that FEFM achieves overload protection in burst period, improves performance significantly, and has the ability to compromise different tradeoffs between throughput and SLA satisfaction.
