Survivable Virtual Network Link Protection Method Based on Network Coding and Protection Circuit

Network coding-based protection

This paper serves as a tutorial lecture on the use of network coding to provide resource efficient, and agile proactive protection. Network coding, which was introduced in [1], allows intermediate network nodes to form linear combinations of packets received on different input links. The use of network coding results in capacity enhancement. This capacity enhancement is used to provide protecti...

Network Design and Protection Using Network Coding

Link and node failures are two common fundamental problems that affect operational networks. Hence, protection of communication networks against such failures is essential for maintaining network reliability and performance. Network protection codes (NPC) are proposed to protect operational networks against link and node failures. Furthermore, encoding and decoding operations of such codes are ...

1+N Network Protection for Mesh Networks: Network Coding-Based Protection Using p-Cycles and Protection Paths

Survivable Network Coding

Given a telecommunication network, modeled by a graph with capacities, we are interested in comparing the behavior and usefulness of two information propagation schemes, namely multicast and network coding, when the aforementioned network is subject to single arc failure. We consider the case with a single source node and a set of terminal nodes. The problem of studying the maximum quantity of ...

Link Protection within an Existing Backbone Network

Conventionally, research efforts targeting the issue of network robustness focus either on imposing resilience in the network design phase, or on augmenting existing network resources. For a given backbone transport network, both these approaches can be inadequate, simply because the network is in an operational phase and augmenting its resources may not be feasible. This study circumvents thes...
