Functional Requirements
Linkage:
- Initial layer-2 connectivity to other gigapops is expected to utilize ATM PVCs from the vBNS plus some dedicated links that may be ATM PVCs or SVCs, or raw SONET links.
- The linkages among gigapop routers connected to wide-area links will typically be provided by high-performance switches, typically either a cell-based or a frame-based service, depending on the needs of each specific gigapop.
