Inter‐Data Center Networks: Routing and Reliability in Virtual Network Backbone
Oussama Soualah, Ilhem Fajjari, Nadjib Aitsaadi · 2021
Few survivable virtual network (VN) embedding algorithms have been proposed in the literature. Indeed, we can classify the related methods into two main groups: (i) centralized and (ii) distributed approaches. Besides, in each group, the reliable VN embedding strategies assume that failures can occur in (i) routers and/or links failures in the whole S N or (ii) in a defined geographic region. Hereafter, we will present a summary of the prominent survivable strategies with respect to more criteria. To do so, first of all, we start by presenting a short overview of the baseline strategies which do not consider the reliability of physical resources. Afterward, we will provide a deep overview of the survivable VN mapping strategies.
