| Popis: |
The digital private network switching system (DPNSS) layer 2 protocol specification does not explicitly indicate methods of layer 2 overload control or link stability verification. An efficient strategy for dealing with DPNSS-compatible exchanges that rapidly retransmit frames has been designed and implemented in the 5ESS-PRX switch to provide high performance and reliability in the DDSN network for the United Kingdom. The strategy is to optimize processor efficiency by ignoring as many frames as possible while keeping the reset probability below 10/sup -8/ and to verify link stability periodically. Periodic transmission of specialized layer 2 test frames over the DPNSS link assures link stability. > |
