Abstract

AbstractWe study the survivable network design problem (SNDP) for simultaneous unicast and anycast flows in networks where the link cost follows All Capacities Modular Cost (ACMC) model. Given a network modeled by a connected, undirected graph and a set of flow demands, this problem aims at finding a set of connections with a minimized network cost in order to protect the network against any single failure. This paper proposes a new Genetic Algorithm with an efficient encoding to solve the SNDP in networks with ACMC model (A-SNDP). Our encoding scheme is simple and allows large search space. Extensive simulation results on real large topology instances show that the proposed algorithm is much more efficient than the Tabu Search and other conventional Genetic Algorithm in terms of minimizing the network cost.

Highlights

There are many types of connection for data transmission over the Internet
In our previous work [12], we have developed a genetic algorithm for A-survivable network design problem (SNDP) called Connection Database based Encoding (CDE)-Genetic algorithm (GA) that uses Connection Database Encoding for individual representation
It is notable that the minimum and the average result found by Connection Encoding (CCE)-GA are better than the one found by Tabu Search and CDE-GA on almost problem instances

Summary

Introduction

There are many types of connection for data transmission over the Internet. The most popular type of connection is from one node to another, which is called unicast. An anycast connection is from one node to another, the difference is that the destination node has a one or many replicated servers which back up for it. Anycast has in recent years become increasingly popular for adding redundancy to many Internet services [1,2,3]. Anycast connection is currently used in many applications such as Domain Name Service (DNS), Web Service, Overlay Network, peer-to-peer (P2P) systems, Content Delivery Network (CDN), software distribution. The popularity of anycast technology will increase in the near future, since many new services that use both unicast and anycast paradigms are being developed
