Label Assignment and Failure Recovery Approaches for IP Multicast Communication in MPLS Networks Omar Qasem Banimelhem, Ph.D. Concordia University, 2005 Multiprotocol Label Switching (MPLS) is an Internet Engineering Task Force (IETF) framework that provides for the efficient designation, routing, forwarding, and switching of traffic flows through the network. MPLS is widely used for multicast ...

PURPOSE To evaluate the in vivo toxicity and efficacy of previously developed poly-(lactide-co-glycolide)-vancomycin-based microparticles (V-MPLs) for eventual use for endophthalmitis prophylaxis during cataract surgery. METHODS The intraocular vancomycin concentration profile was evaluated after V-MPL injection into the anterior chamber of rabbit eyes. The toxicology of V-MPLs versus MPLs al...

MPLS networks have evolved over the last 10-15 years and have become critically important for ISPs. MPLS is primarily used in two ways: to perform traffic engineering in IP networks, providing greater determinism and more efficient usage of network resources; and for enabling MPLS based L2 or L3 enterprise Virtual Private Network (VPN) services, which continues to be one of more profitable serv...

Multi-Protocol Label Switching is useful in managing multimedia traffic when some links are too congested; MPLS Traffic Engineering is a growing implementation in today's service provider networks. In This paper we propose an improvement of MPLS-TE called EMPLS-TE, it is based on a modification of operation of Forwarding Equivalence Class (FEC) in order to provide the quality of service to stre...

This document specifies an initial set of identifiers to be used in the Transport Profile of Multiprotocol Label Switching (MPLS-TP). The MPLS-TP requirements (RFC 5654) require that the elements and objects in an MPLS-TP environment are able to be configured and managed without a control plane. In such an environment, many conventions for defining identifiers are possible. This document define...

Recently, 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 transparent to traceroute probing. Additional techniques have been proposed to reveal the presence of MPLS tunnels when they do not explicitly appear in traceroute. It has been shown that MPLS is a very well deployed ...

Ethernet pseudowires are widely deployed to support packet transport of Ethernet services. These services in-turn provide transport for a variety of client networks, e.g., IP and MPLS. This document uses procedures defined in the existing IETF specifications of Ethernet pseudowires carried over MPLS networks. Many of the requirements for the services provided by the mechanisms explained in this...

The MPLS Transport Profile (MPLS-TP) is a profile of the MPLS technology for use in transport network deployments. The work on MPLS-TP has extended the MPLS technology with additional architectural elements and functions that can be used in any MPLS deployment. MPLS-TP is a set of functions and features selected from the extended MPLS toolset and applied in a consistent way to meet the needs an...
