Virtual Private LAN Service (VPLS) is a way to provide Ethernet-based multipoint to multipoint communication over IP or MPLS networks. It allows geographically dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudo-wires. The term ‘sites’ includes multiplicities of both servers and clients.
VPLS is a virtual private network (VPN) technology. In contrast to L2TPv3, which allows only point-to-point layer 2 tunnels, VPLS allows any-to-any (multipoint) connectivity.
VPLS Service Benefits
- Cost efficiencies: Leverage multiple services on a single port and Ethernet access circuit to reduce access costs and provide flexible bandwidth allocations across services.
- Secure networking environment: Leverages the aggregation of several global MPLS networks to create a private path — isolated from other customers’ domains.
- Flexibility and scalability: Wide range of speeds — Fast E, Gig E and beyond, with up to six CoS / QoS levels for traffic prioritization during high-growth periods.
- Maintain network control: Customer end-to-end control of WAN routing and protocol decisions, including protocol transparency.
- Global connectivity. Availability in markets across North America, Europe, Latin America, Asia, Middle East and Africa.
- Multi-service ports. Multiple services (e.g. MPLS/IP VPN, Internet, EVPL) supported on a single VPN port and Ethernet access circuit.
- Smart Demarcation. End-to-end connectivity fault management and remote testing through a standard Network Interface Device (NID).
- End-to-end service level guarantees. Key performance metrics include latency, data delivery, utilization and jitter.
- Hybrid Layer 2 VPLS and Layer 3 MPLS/IP VPN. High-speed Ethernet for large locations and MPLS IP VPN services to interconnect smaller sites.
