Multicast fast re-route schemes for multiflow case
Oleksandr V. Lemeshko, Arus Kinan, Mohammed A.jabbar A. Wahhab · 2015
Schemes for protection of a node, a link and a rout under fault-tolerant multicast routing are presented for a multiflow case. The schemes are based on a nonlinear flow model which has the conditions for preventing links overload modified for a case when not all flows can switch to backup routs but only some of them. Scheme operability is demonstrated on a numerical example which has proven effectiveness of the proposed solution for the multiflow case.
