Tellabs has demonstrated the dynamic delivery of IP services over an optical core using a GMPLS control plane with routing. The test, which was conducted at the Isocore Internetworking Lab, used the new Tellabs 8820 multi-service switch router, the Tellabs 5500 NGX-S transport switch and the Tellabs MetroWatch element manager’s GMPLS software. During the Isocore testing, the Tellabs 8820 multi-service switch router combined the functionality of an edge router, ATM multi-service switch, Frame Relay switch and Ethernet edge switch into one platform. The Tellabs 8820 multi-service switch router interoperated and enabled three MPLS-based applications during the Isocore multi-vendor testing:
- Layer 2 VPNs using the IETF Martini draft, which defines point-to-point MPLS connections that support virtual local networks or Frame Relay/ATM;
- Layer 3 VPNs using the IETF’s RFC-2547bis specification, which enables IP/MPLS-based IP VPNs
- Virtual Private LAN services (VPLS) using the IETF’s VPLS-over-MPLS draft, which enables carriers to offer point-to-point or point-to-multi-point WAN extensions of customers’ LAN-based Ethernet networks
Tellabs said its MetroWatch element manager’s GMPLS software enabled the first- ever interworking between the IETF’s GMPLS and ITU’s OIF-UNI specifications for signaling between the IP routing network and optical transport network.

- In September 2003, Tellabs introduced a new carrier-class, medium capacity (42 Gbps) “managed edge” platform designed to extend IP/MPLS from the edge of the core network to the local exchange or even to the customer premises. The new Tellabs 8600 system could be used by service providers to implement MPLS VPNs and Ethernet over MPLS, delivering application aware services such as intranet interconnectivity, extranet, business Internet access and corporate voice with QoS.
