Importance of Multicast Virtual Private Networks Based on RFC 2547
The Multi-protocol Label Switching is one of the proposed technologies useful for traffic engineering in the specific aspects of measurement and control of Internet traffic and Virtual Private Network (VPN) is a concept that significant on the future of business communication, it replace existing private network with flexible architecture that is easily manage and at a same time it provide enhanced service. The Multi-Protocol Label Switching (MPLS) Virtual Private Network (VPN) is a popular IP VPN service based on RFC 2547 and its successor documents (dubbed 2547bis). The main importance of MPLS is that it integrates the key features of both Layer 2 and Layer 3. Most importantly, it is not limited to any Layer 2 or Layer 3 protocol.
