Integration of Network Technology MPLS based VPN: A model for establishing Virtual learning facility for multiple locations
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2012, Vol 2, Issue 5
Abstract
Multi Protocol Label Switching (MPLS) is a mechanism in high-performance telecommunications networks that directs voice, video and data on the internet from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links (paths) between distant nodes rather than endpoints. MPLS can encapsulate packets of various network protocols. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay and DSL. MPLS based Virtual Private Networks (VPN) tie together give the flexibility to transport and route several types of network traffic using the technologies of a MPLS backbone. Multi Protocol label Switching (MPLS) is a core networking technology that operates between Layers 2 and 3 of the OSI model. Sometimes it is also referred to as a layer 2.5 technology. It is basically a framework for WAN. MPLS is a highly evolved than its predecessors Frame relay and ATM in terms of providing solution for VPN, QOS, network convergence, security, traffic engineering etc. As a result, today MPLS is widely used in supporting applications like voice, video and data on the internet. Most service providers are migrating their backbone network from traditional Frame Relay and ATMs to MPLS. MPLS is a technology which is here to stay for a long time. This report basically deals with the implementation of MPLS as VPN service, how it is implemented, maintained, pros and cons.
