Network Restoration for Next-Generation Communication and Computing Networks

Table 1

Summary of network restoration models employed in current communication and computing networks.

Number	Type of network restoration model	Type of failures addressed	Applicable networks	References
(1)	Path restoration, for example, shortest cycle backup path, minimal joint failure probability, and end-to-end restoration.	Link failures (single and multiple links) and node failures	Teletraffic networks, optical communication networks, mesh networks, and computing networks	[17–21]
(2)	Link (or line) restoration	Link failures (single or multiple failures) and node failures	Teletraffic networks	[22]
(3)	Proactive restoration, for example, connection-based and load-directed restoration models	Node failures and joint link failures	Optical communication networks and computing networks	[23, 24]
(4)	Reactive restoration	Link failures and node failures	Mesh networks	[25]
