| AutoRoute
Connection management software | Automates the management of virtual circuits and bandwidth allocation by routing and rerouting virtual connections over optimal paths through the network.
Tracks resources designated to individual connections. Reroutes virtual circuits to alternate network paths in the event of a trunk or switch failure. | Simplifies the management of huge numbers of connections found in an ATM system.
Prevents system overloading and ensures that users receive their quality of service (QOS). Provides uninterrupted service and high reliability for users, without relying on a centralized network management system. |
| OptiClass
Class of service features | Supports up to 16 network-wide service classes, with minimum service guarantee for each class. | Enables network administrators to customize service offerings to meet the requirements of their specific applications. |
| ForeSight
Closed-loop traffic management and congestion avoidance system. | Continuously monitors trunk utilization and adjusts connection throughput on a per-connection basis. | Enables up to 95% utilization of network bandwidth (compared to 50-70% utilization experienced with open-loop mechanisms). |
| FairShare
Per-virtual circuit queuing and rate scheduler. | Fairly allocates bandwidth by providing "firewalls," unlike a shared buffer scheme. | Prevents one misbehaving connection from affecting the performance of others. Provides fair access to bandwidth for all users. |
