With the advent of fog and edge computing paradigms, computation capabilities have been moved toward the edge of the network to support the requirements of highly demanding services. To ensure that the quality of such services is still met in the event of users' mobility, migrating services across different computing nodes becomes essential. Several studies have emerged recently to address service migration in different edge-centric research areas, including fog computing, multi-access edge computing (MEC), cloudlets, and vehicular clouds. Since existing surveys in this area focus on either VM migration in general or migration in a single research field (e.g., MEC), the objective of this survey is to bring together studies from different, yet related, edge-centric research fields while capturing the different facets they addressed. More specifically, we examine the diversity characterizing the landscape of migration scenarios at the edge, present an objectivedriven taxonomy of the literature, and highlight contributions that rather focused on architectural design and implementation. Finally, we identify a list of gaps and research opportunities based on the observation of the current state of the literature. One such opportunity lies in joining efforts from both networking and computing research communities to facilitate future research in this area. [ABSTRACT FROM AUTHOR]

The article presents information on a survey of several research challenges in interdomain routing. It is considered as a challenging research area, which is mainly rooted in two main areas. First. the interdomain routing protocol currently used in the Internet has several limitations, but its replacement is not a realistic option due to its worldwide deployment. Second, these interdomain routing denotes routing among distinct domains are networks. The Internet is a decentralized collection of computer networks from all around the world. These networks are known as a domains or an autonomous systems (AS). An AS is a network or group of networks under a common routing policy and managed by a single authority. The current Internet is basically the interconnection of more than 20,000 ASes. Each of these ASes usually uses one or more interior gateway protocols, such as Intermediate System to Intermediate System or Open Shortest Path Firs, to exchange routing information within the AS, known as intradomain routing. This interdomain routing focuses on the exchange of routes to allow the transmission of packets between different ASes.
