This document presents a generic connection admission control (GCAC) reference model and algorithm for IP-/MPLS-based networks. Service provider (SP) IP/MPLS networks need an MPLS GCAC mechanism, as one motivational example, to reject Voice over IP (VoIP) calls when additional calls would adversely affect calls already in progress. Without MPLS GCAC, connections on congested links will suffer d...

Recent researches have stated the fast deployment of IPv6. It has been demonstrated that IPv6 grows much faster, being so more and more adopted by both Internet service providers but also by servers and end-hosts. In parallel, researches have been conducted to discover and assess the usage of MPLS tunnels. Indeed, recent developments in the ICMP protocol make certain categories of MPLS tunnels ...

BGP/MPLS VPN is recently receiving much attention from industries and standard bodies. It enables ISP to provide IP-service with QoS guarantee to the customers over shared MPLS backbone. In this paper, we present a resilient path management mechanism for BGP/MPLS VPN. An existence condition for finding fast backup path which satisfies the resilience constraint is derived for a full mesh BGP/MPL...

In 802.16 standards, PHS suppresses redundant parts of payload header in MAC service data unit. This paper proposes Label Switched Path-Payload Header Suppression (LSPPHS), in which an MPLS-enabled backbone route compresses packets over an MPLS LSP without compression or decompression cycles at each router. It has two main contributions for MPLS-IPv6 header compression. First, LSPPHS adds a new...

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract Multi-Protocol Label Switching (MPLS) has been extended to encompass point-to-multipoint (P2MP) Label Switched Paths (LSPs). As with point-to-point MPLS LSPs, the requirement to detect, handle, and diagnose control ...

The framework for MPLS in transport networks (RFC 5921) provides reference models for the MPLS Transport Profile (MPLS-TP) Transport Service Interfaces, which are a User-to-Network Interface (UNI), and a Network-to-Network Interface (NNI). This document updates those reference models to show detailed reference points for these interfaces, along with further clarification of the functional archi...

Multi-Protocol Label Switching (MPLS) is in the process of standardization by the Internet Engineering Task Force (IETF). It is regarded as a technology for traffic engineering and QoS in IP-networks. In this paper, we address the management of MPLS networks, which is crucial for large networks. We decided to follow the IETF Policy Framework approach and extended the Common Information Model (C...

Mobile MPLS (Multi Protocol Label Switching) is a new technique which integrates the Mobile IP (MIP) and MPLS and thus inherits the advantages of both. MIP supports the mobility whereas MPLS provides faster streaming throughout the network, hence providing requisite QoS to the application. The objective of this paper is to survey the efforts that have been done to enhance the MIP functionality ...

MPLS (Multiprotocol Label Switching) technology is the solution to the performance requirements of the next generation IP core networks. Unfortunately, the existing architecture for MPLS ignores multicast support. Besides, the existing solutions cover a limited scope in supporting multicast services in MPLS. In this paper, we propose a general architecture to support all IP multicast routing pr...

Multi-Protocol Label Switching (MPLS) is in the process of standardization by the Internet Engineering Task Force (IETF). It is regarded as a technology for traffic engineering and QoS in IP-networks. we proposed a IETF Policy-based Network Management Framework and policies with MPLS specific classes. It uses a three-level policy architecture, which includes managing on device, network, and ser...
