Network coding-based protection

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

Neural Network Based Protection of Software Defined Network Controller against Distributed Denial of Service Attacks

Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...

Multicast 1+1 protection: The case for simple network coding

We discuss how the idea of unicast 1+1 protection can be efficiently extended to protect multicast connections in optical backbone networks. Particularly, we show how to achieve instantaneous failure recovery and cost efficiency by allowing intermediate nodes to merge their incoming flows by a simple network code, i.e., logical OR operation. Under simple network coding, the problem of minimum c...
