“…The authors conclude that for packet loss probabilities smaller than 0.3 % head-of-line blocking in TCP does not introduce a significant performance decrease compared to SCTP. A similar work [43] finds no significant differences between SCTP and TCP with selective acknowledgments. However, these simulation results contradict recent measurements based on FreeBSD [44].…”

Firewalls are a crucial building block for securing IP networks. The usage of out-ofband signaling protocols such as SIP for IP telephony and multimedia applications requires a dynamic control of these firewalls and imposes several challenges. Recently, several firewall control architectures and protocols have been developed. The main focus of this paper is the Simple Middlebox Configuration Protocol (SIMCO), which is a new transactionbased firewall control protocol. Due to the impact on call setup delays, firewall signaling requires small end-to-end delays and thus mandates a careful choice of the transport protocol. Therefore, this paper studies SCTP, TCP and UDP-based transport for SIMCO and compares different configurations that allow to optimize the performance. We present an analytical model to quantify the impact of head-of-line blocking in SCTP and TCP and verify it with measurements. Both the model and measurements reveal that SCTP can significantly reduce the SIMCO response times by leveraging transmission over multiple parallel streams. While already a few SCTP streams can almost completely avoid headof-line blocking, our results show that TCP-and UDP-based transport may suffer from significantly larger delays.

Carriers have adopted session initiation protocol (SIP) in their next generation networks. Providing carriergrade service requires high availability in times of component failures, avalanche restart, flash crowds and denial of service attacks, which cause overload on SIP servers. Throughput of SIP servers is largely degraded during overload. We propose an SIP overload control (SIP-OC) solution for local and remote situations, working in hop-by-hop and end-to-end modes. Our local SIP-OC method uses a cross-layer approach with negligible performance impact, while the implicit nature of our remote SIP-OC allows detection of sophisticated overload conditions such as those caused by non-SIP entities. Our remote SIP-OC uses transaction response time as the basis for implicit overload detection. Coupling our local and remote SIP-OC schemes, we show that the range of 'sustainable' overload that can be imposed on the system improves significantly. Moreover, incorporating a 2-means filtering mechanism into our SIP-OC scheme makes it perform well under packet-loss. We also show that our proposed solution is robust to network latency and SIP server capacity fluctuations. All of our results are obtained from experiments over SIP testbeds including an experimental IP multimedia subsystem. Figure 1. Basic session initiation protocol signaling (not showing DNS and location server for simplicity).In this paper, we propose a total SIP overload control (SIP-OC) solution including a remote SIP-OC mechanism operating between two SIP servers, namely, AIWB ‡ and a local SIP-OC scheme with almost no performance impact used at the edge, namely, SYN-dropping § . Unlike other local SIP-OC approaches, SYN-dropping is a cross-layer approach and is only triggered for independent SIP UAs running over TCP, while back-to-back user agents (B2BUA), which are in fact dense port SIP clients use AIWB. For experiments, we adopt TCP at the UA-edge and UDP at the edge-core segment of the SIP network. Nevertheless, UDP SIP clients can still continue to connect to the edge proxy. At the core, UDP is used, which improves scalability [11]; however, AIWB can operate on top of any transport mechanism as it resides entirely in the SIP layer.We will show the benefits that can be gained from combining an implicit remote SIP-OC mechanism with SYN-dropping in terms of improved network sustainability over a large range of overload. We use transaction response time (TRT) denoted by TRT (time from INVITE to any provisional response such as, 183-Session-In-Progress/OK/etc.) measured by the upstream server as an implicit indication of overload at some downstream server. Using this information, the upstream server controls the signaling load imposed on the downstream server using an adaptive window-based approach without any assistance from the overloaded server.Although we do not argue against the use of explicit SIP-OC methods, our point is to show the added benefit and feasibility of using an implicit SIP-OC mechanism, which can be integrated alongside an explicit SI...

With the proliferation of the Internet, voice over IP and multimedia communication become more and more important. One of the protocol that facilitated this development is Session Initiation Protocol (SIP). SIP is a signaling protocol which manages the session establishment and termination. It can be based on UDP or TCP at the transport layer. In this paper, the strengths and weaknesses of SIP over UDP and TCP are analyzed in satellite environment. The performance issues of SIP related to transport layer over the next generation protocol, IPv6, are studied. The experimentation is carried out on the satellite network testbed at Centre for Communication Systems Research (CCSR), University of Surrey. The results show that SIP performance on UDP is better than on TCP. SIP over TCP, requires more retransmissions due to the congestion control and flow control mechanisms of TCP, resulting in larger call setup time and bandwidth consumption.
