Network Protection

Ring cover is a type of mesh-based protection technique to apply the traditional ring protection techniques such as unidirectional path switched ring (UPSR) and bidirectional line switched ring (BLSR) to a mesh-based network. For a simple network, it may be possible to employ a single ring to cover all the links of the network. However, [...]

Traditional span-protecting p-cycles offer protection for those on-cycle spans and straddling spans. On-cycle spans are referred to as the spans on a p-cycle itself, while straddling spans are referred to as the spans, who are not on the p-cycle, but whose two end nodes are on the cycles. P-cycles are an advanced span protection technique. [...]
