Sequential Routing
Figure 1-10 Concurrent Routing
The CR Feature provides the following benefits:
•
Allows a node to initiate multiple simultaneous route requests
•
Allows multiple route requests to be accepted and serviced by a node
•
Allows the degree of route concurrency to be configured on a node-by-node basis, which provides
the user the ability to tailor the application of CR to a specific network topology
•
Implements a CPU throttling mechanism; whereas, route concurrency is limited if CPU usage
becomes too high
•
Includes new statistics on CR-related quantities and CPU-based route throttling
•
Includes a mechanism to automatically measure nodal settling time and maintain a history of settling
time measurements
•
Increases network availability
•
Reduces network settling time
