Simulation of the SCTP Failover Mechanism
نویسنده
چکیده
Some features of SCTP provide opportunities for creating redundancies for signalling over IP networks. This paper presents the behaviour of SCTP in failover scenarios, based on literature review and simulations. Simulations were carried out using NS2 in a multi-homing environment. It was found, as expected, that when failover took place, the undelivered chunks were retransmitted to the secondary path while new messages were still transmitted to the primary path until the error count was exceeded whereupon the primary path was declared inactive and a new primary path was chosen. The simulations raised some concerns regarding the duration of failover for different PRL values. *

Impact of Traffic Load on SCTP Failovers in SIGTRAN
With Voice over IP (VoIP) emerging as a viable alternative to the traditional circuit-switched telephony, it is vital that the two are able to intercommunicate. To this end, the IETF Signaling Transport (SIGTRAN) group has defined an architecture for seamless transportation of SS7 signaling traffic between a VoIP network and a traditional telecom network. However, at present, it is unclear if t...
متن کاملPerformance Evaluation of SCTP as a Transport Layer Protocol Master’s Thesis in Computer Network Engineering
TCP and UDP are the most popular transport protocols used for end-end data transmission. The rapid growth of internet leads to development of many innovative applications in the current environment. Depending on the functionality of these applications, requirements of transport protocols are changing. TCP is known for its problems with Head Of Line blocking (HOL) and SYN attacks which gives red...
متن کاملImpact of sack delay and link delay on failover performance in SCTP
The Stream Control Transmission Protocol (SCTP) was developed to support the transfer of telephony signaling over IP networks. One of the ambitions when designing SCTP was to offer a robust transfer of traffic between hosts. For this reason SCTP was designed to support multihoming, which gives the possibility to set up several paths between the same hosts in the same session. If the primary pat...

Multi-homing at the transport layer is a mechanism that ties one transport layer association to several network interfaces at each communication host, which enabling the two end-nodes to exchange data over several network paths. Stream control transmission protocol (SCTP) supports multi-homing feature. We suggest Concurrent Multipath CommunicationSCTP (CMC-SCTP) which uses multi-homing as a bas...
متن کاملDelay-Centric Handover in SCTP
The introduction of the Stream Control Transmission Protocol (SCTP) has opened the possibility of a mobile aware transport protocol. The multihoming feature of SCTP negates the need for a solution such as Mobile IP and, as SCTP is a transport layer protocol, it adds no complexity to the network. Utilizing the handover procedure of SCTP, the large bandwidth of WLAN can be exploited whilst in the...
