Discovery of BGP MPLS VPNs
BGP/MPLS VPN is a mechanism defined in IETF RFC 2547 that allows service providers to use their IP backbone to provide VPN services. This mechanism is based on using BGP to distribute VPN routing information to the routers in the backbone network and using MPLS to forward VPN traffic. MPLS tunnels are created dynamically when needed, which relieves service providers of pre-provisioning tens of ...
متن کاملBuilding MPLS VPNs with QoS Routing Capabilty
Recently MPLS is used for building up VPNs in IP backbone, called MPLS VPNs. In this paper, we discuss issues on finding routes with QoS requirements (i.e., QoS routing) in MPLS VPNs. We first present background on MPLS VPNs as well as QoS routing. Then we discuss both the benefits and problems resulted from introducing QoS routing into MPLS VPNs. We particularly present an architecture of MPLS...

متن کاملRestoration Routing Using MPLS-TE
The increasing demand for multimedia applications such as VoIP and video streaming has created new challenges for network service providers. The requirements of delay, throughput and packet loss for such applications are inherently different from those of data traffic. The IP service, which is characterized as best effort and performs satisfactorily with data traffic, fails to provide the desir...
متن کاملOSPF for BGP / MPLS IP VPNs
Many Service Providers offer Virtual Private Network (VPN) services to their customers, using a technique in which customer edge routers (CE routers) are routing peers of provider edge routers (PE routers). The Border Gateway Protocol (BGP) is used to distribute the customer’s routes across the provider’s IP backbone network, and Multiprotocol Label Switching (MPLS) is used to tunnel customer p...
