Abstract: Wide-area data communications utilize regional networks transporting IP-over-Ethernet on fiber. For certain Layer 2 services, a regional implementation of the network makes limited use of spanning tree protocol on a backbone ring. Learning bridge operations in switches on associated access rings involve a short default for an aging timer. For use of Open Shortest Path First (OSPF), the connection of each access ring to the backbone ring uses a pair of routers with dual links therebetween. One of these links is bonded to the backbone (OSPF Area 0), whereas the other link is bonded to the Area of the respective access ring. Also, certain routers within each regional network form a mini-autonomous system, for boundary gateway protocol (BGP). The mini-autonomous systems of the regional networks form a confederation. The network utilizes route reflectors in the mini-autonomous systems. The Internet carries confederation commands to and from a designated hub.

Abstract: An automated service level manager (SLM) provides operations support for wide-area data communication services offered via regional IP-Over Ethernet on fiber networks. The SLM comprises a suite of software components and associated hardware running the software, to communicate with agents throughout the networks, to accumulate various network operations data for reports and alarms and to provide instructions to control network operations. The SLM preferably offers a web server type user interface. This interface enables access by technical personnel of the carrier, for example from a network operations center. This interface also offers access to customers having or seeking service through the network.
