This paper proposes three innovative point-to-multipoint protection schemes to provide efficient and reliable MPLS transport profile multicast services, which is particularly relevant for the fast growing IPTV broadcast service. The three proposed protection schemes are all based on the interconnected rings structure, which is a widely deployed topology of legacy networks and has the natural ability...
A traffic engineered label switched path (TE-LSP) is usually deployed on an optimally computed path. In complex network scenarios, or when external nodes like path computation elements (PCEs) are solicited in a distributed manner, the already resource hungry task of optimal path computation could take a considerable amount of time during which network resources may fluctuate. This could result in...
This paper proposes an adaptive resource reservation protocol for high-speed resource information advertisement. The adaptive resource reservation protocol (ARRP) is a protocol that adaptively decides whether to uses a 1-way reservation scheme or 2-way reservation scheme on the basis of resource information in the route calculation. Examples of the resource information are unreserved bandwidth and...
