Designing and Implementing IP MPLS-Based Ethernet Layer 2 VPN Services: An Advanced Guide for VPLS and VLL

A guide to designing and implementing VPLS services over an IP/MPLS switched service provider backboneToday's communication providers are looking for convenience, simplicity, and flexible bandwidth across wide area networks-but with the quality of service and control that is critical for business networking applications like video, voice and data. Carrier Ethernet VPN services based on VPLS makes this a reality. Virtual Private LAN Service (VPLS) is a pseudowire (PW) based, multipoint-to-multipoint layer 2 Ethernet VPN service provided by services providers By deploying a VPLS service to customers, the operator can focus on providing high throughput, highly available Ethernet bridging services and leave the layer 3 routing decision up to the customer.Virtual Private LAN Services (VPLS) is quickly becoming the number one choice for many enterprises and service providers to deploy data communication networks. Alcatel-Lucent VPLS solution enables service providers to offer enterprise customers the operational cost benefits of Ethernet with the predictable QoS characteristics of MPLS.Items Covered:Building Converged Service Networks with IP/MPLS VPN TechnologyIP/MPLS VPN Multi-Service Network OverviewUsing MPLS Label Switched Paths as Service Transport TunnelsRouting Protocol Traffi c Engineering and CSPFRSVP-TE ProtocolMPLS Resiliency — Secondary LSPMPLS Resiliency — RSVP-TE LSP Fast RerouteLabel Distribution ProtocolIP/MPLS VPN Service Routing ArchitectureVirtual Leased Line ServicesVirtual Private LAN ServiceHierarchical VPLSHigh Availability in an IP/MPLS VPN NetworkVLL Service ResiliencyVPLS Service ResiliencyVPLS BGP Auto-DiscoveryPBB-VPLSOAM in a VPLS Service Network
