Session Initiation Protocol is a core protocol for coming real time communication networks, including VoIP, IMS and IPTV networks. Based on the open IP stack, it is similarly susceptible to Denial-of-Service Attacks launched against SIP servers. More than 20 different research works have been published to address SIP-related DoS problems. In this survey we explain three different types of DoS a...

This document provides a methodology for benchmarking the Session Initiation Protocol (SIP) performance of devices. Terminology related to benchmarking SIP devices is described in the companion terminology document (RFC 7501). Using these two documents, benchmarks can be obtained and compared for different types of devices such as SIP Proxy Servers, Registrars, and Session Border Controllers. T...

Combining high throughput sequencing with stable isotope probing (HTS-SIP) is a powerful method for mapping in situ metabolic processes to thousands of microbial taxa. However, accurately mapping metabolic processes to taxa is complex and challenging. Multiple HTS-SIP data analysis methods have been developed, including high-resolution stable isotope probing (HR-SIP), multi-window high-resoluti...

Session Initiation Protocol (SIP) is a control protocol standardized by IETF and implemented on the application layer. It can be used to establish, modify, and terminate Internet conferencing, telephony and some other multimedia sessions.[1] SIP uses server and client architecture, Peer-toPeer (P2P) is another popular technology that accomplishes the same functionality in an overlay network whe...

The concept of network virtualization, such as network functions virtualization, has attracted considerable attention from telecom carriers and a live migration technique is a key feature of virtualization technology. However, there are some challenges associated with applying server virtualization technology including live migration to a SIP server. Previous work has not dealt with the perform...

SPAM, defined as sending unsolicited messages to someone in bulk, might be a problem on SIP open-wide deployed networks. The responsibility for filtering or blocking calls can belong to different elements in the call flow and may depend on various factors. This document defines an authorization based policy language that allows end users to upload anti-SPIT policies to intermediaries, such as S...

In this work, Session Initiation Protocol model is established by using Timed Colored Petri Nets (TCPN). SIP (Session Initiation Protocol) is a protocol developed to assist in providing advanced telephony services across the Internet. The Session Initiation Protocol (SIP) has become the quasi-standard for VoiceoverInternet Protocol (VoIP) communications. SIP is based on a client-server infrastr...

For Internet-centric usage, the number of SIP-required standards for presence and IM and audio/video communications can be drastically smaller than what has been published by using only the rendezvous and session-initiation capabilities of SIP. The simplification is achieved by avoiding the emulation of telephony and its model of the intelligent network. ’Simple SIP’ relies on powerful computin...

SIP is a call control and signalling protocol that was adopted by the 3GPP to deliver IP multimedia services to the mobile network. Cross platform IP-telephony service creation is a challenging task. Although, the emergence of JAIN-SIP has reinforced the development and implementation of platform-independent IP-telephony services, the development of advanced cross-platform SIP (Session Initiati...
