Path Restoration Versus Link Restoration in Survivable ATM Networks Oumar Mandione Gueye, Isaac Woungang, Sanjay Kumar Dhurandher, Faria Khandaker, and A. B. M. Bodrul Alam 1 Introduction In today’s society, business, political, and social activities happen in a fast manner. Information needs to be sent across different parties involved almost instantly. In view of this, ATM networks have played a major role in both local area networks (LANs) and wide area network (WANs). This is because ATM networks outshine the older generation of network technologies by being able to provide larger bandwidth, different quality of services (QoS), guaranteed throughputs, as well as bounded delays for different kinds of traffic, including data, voice, video, and even mixtures of these. These points make the ATM technology one of the best communication technologies for certain types of telecommunication applications in today’s world. However, the more heavily a network is relied on, the more disastrous it becomes if failures happen to it [1]. This has motivated the design of survivable ATM. Different O. M.
