“…An important conclusion following from this subsection and the previous one is that fast recovery of the affected flows (especially essential for real-time services with stringent requirements on availability and reliability such as Voice-over-IP [52], [73]) is possible by the application of local protection schemes. These methods involve short backup paths installed before the failure and eliminate the need to send the end-to-end notifications along the working path [65].…”

In order to meet their stringent dependability requirements, most modern communication networks support fast-recovery mechanisms in the data plane. While reactions to failures in the data plane can be significantly faster compared to control plane mechanisms, implementing fast recovery in the data plane is challenging, and has recently received much attention in the literature. This survey presents a systematic, tutorial-like overview of packet-based fast-recovery mechanisms in the data plane, focusing on concepts but structured around different networking technologies, from traditional link-layer and IP-based mechanisms, over BGP and MPLS to emerging software-defined networks and programmable data planes. We examine the evolution of fast-recovery standards and mechanisms over time, and identify and discuss the fundamental principles and algorithms underlying different mechanisms. We then present a taxonomy of the state of the art and compile open research questions.<br>

“…Soft switch technology is the core technology of NGN, VAP draws on the advantages of IP, ATM and TDM to form a layered, fully opened architecture. Its core idea is software, through the software to achieve the original switch control, connection and business processing functions [7] [8]. The entities are connected and communicated through standard protocols.…”

The next generation network (NGN) is the core of Soft switch technology, it can provide the network architecture including voice, data, video and multimedia services. This paper presents a design method of Value-added Application Platform (VAP) based on Linux operating system for constructing NGN application server, its core is software. Based on this platform, developers can quickly and in a low cost way to develop a variety of value-added services. As rapid business development platform, VAP encapsulates a highly efficient and flexible layer of C++ API interface, so it is more easily and quickly to develop the server business.

“…Several FEC techniques such as low density parity check (LDPC) and REED Solomon (R-S) codes etc., are used to recover from packet losses [10,11]. In link recovery, each primary path has a back path or collection of backup path.…”

The need for real-time multimedia applications like streaming video, VOIP has increased over commercial organizations, reliability and availability has become important issues. Such Networks are prone to failures because of different reasons (e.g. unreliable equipment, software bugs or cable cut). Such faults and failures may affect the operation of LSPs and cause packet loss. VoIP packets are sensitive to packet losses and transmission delay to assure correct communication. This paper proposes Efficient Fault Recovery Two Phase Routing for VoIP Applications and its performance based on forward error correction technique. With this approach packet losses against link failures can be recovered by using Vandermonde Matrix Level FEC mechanism. VoIP packets can be routed in two phases in contrast to the traditional single path routing approach to perform load balancing. Simulation results are reported to show the efficiency of the proposed technique when compared with single path routing for effective VoIP flows.
