This document presents a set of requirements for Point-to-Multipoint(P2MP) Traffic Engineered (TE) Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs). It specifies functional requirements for solutions in order to deliver P2MP applications over a MPLS TE infrastructure. It is intended that solutions that specify procedures for P2MP TE LSP(More)
Two packing algorithms for traffic-engineered label-switched paths (TE-LSP) are proposed in order to efficiently accommodate point-to-point (P2P) and point-to-multipoint (P2MP) TE-LSPs in a multi-protocol label switching (MPLS) network. Computer simulation results show that these algorithms calculate more efficient routes and accommodate more LSPs than a(More)
This document describes extensions to Resource Reservation Protocol Traffic Engineering (RSVP-TE) for the set up of Traffic Engineered (TE) point-to-multipoint (P2MP) Label Switched Paths (LSPs) in MultiProtocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. The solution relies on RSVP-TE without requiring a multicast routing protocol in the(More)
The fabric architecture, which can realize massive packet forwarding even with small switches/routers, has been widely used as a network infrastructure in data centers in order to achieve high scalability and low cost. In carrier networks, large scale routers have been adapted as core routers due to the requirement of high density for accommodating a large(More)
The Path Computation Element (PCE) provides path computation functions in support of traffic engineering in Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. Extensions to the MPLS and GMPLS signaling and routing protocols have been made in support of point-to-multipoint (P2MP) Traffic Engineered (TE) Label Switched Paths (LSPs).(More)
