Network coding-based protection
نویسندگان
چکیده
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 protection channels which are used to carry combinations of redundant data, and are solved by the receivers in order to recover data lost due to network failures. The paper starts by addressing network coding-based protection of bidirectional unicast connections, and explains the use p-Cycles to carry linear combinations of the redundant data units. The paper also discusses an earlier protection strategy which is based on diversity coding, in which the linear combinations are formed at special nodes, including sources, and is used to protect unidirectional connections. A generalized network coding-based protection which uses a tree to carry the linear combinations will be presented. Protection of multicast connections using network coding is also explained

Network Coding and Wireless Physical-layer Secret-key Generation: From Unequal Erasure Protection (UEP) to Unequal Security Protection (USP)
The general abstraction of this thesis is the relationships between two seemingly unrelated topics, which are network coding and wireless physical-layer secret-key generation (WPSG). As build-ups to such relationships, some specific aspects of each topic are discussed in detail at first. To begin with, network coding issues of unequal erasure protection (UEP) and degree distribution distortion ...

A novel predictive PCE-based protection strategy for resilient transport networks
The ever increasing requirements of new Internet applications are pushing to optimize the design of optical networks. A key design criterion in network design is the ability to recover from failures in an agile and e cient manner. Protection capabilities are highly required in optical networks since the failure of an optical link might potentially lead to a signi cant tra c loss. Under this con...

In order to improve the quality of video transmission over wireless relay system, some of the studies using Network Coding (NC) and Forward Error Correction (FEC) have been studied. In this paper, layered video streaming using scalable video coding (SVC) based on prioritized network coding is investigated. We propose a novel network coding scheme (prioritizedNC) in order to improve the quality ...
متن کاملAdaptive Protection Based on Intelligent Distribution Networks with the Help of Network Factorization in the Presence of Distributed Generation Resources
Factorizing a system is one of the best ways to make a system intelligent. Factorizing the protection system, providing the right connecting agents, and transmitting the information faster and more reliably can improve the performance of a protection system and maintain system reliability against distributed generation resources. This study presents a new method for coordinating network protect...
