Measures reported by PsLinkDataTest
PacketShaper's access-link monitoring feature allows PacketShaper to deal with this “imperfect” load-balancing issue and has the ability to respond to the occurrence of WAN link failure. When access-link monitoring is enabled, PacketShaper can adjust partitions appropriately to prevent overloading any given WAN link and to account for lost available capacity due to router or link failure. In order to optimize bandwidth usage, minimize traffic congestions, and maximize the speed of WAN links, administrators need to define the WAN links requiring traffic acceleration in the PacketShaper Load Balancer, set the bandwidth limit for each of the links for receiving/sending data, and associate each link with traffic shaping policies. But, once the configuration is complete, it is essential for the administrators to test the correctness of the configuration. For this, administrators can use the PsLinkDataTest test. For each WAN link configured in the target load balancer, this test reports real-time metrics of the volume of traffic handled by the link and data retramissions over the link. This way, the test reveals those links that are candidates for fine-tuning, owing to their low throughput despite the traffic shaping and acceleration rules that apply to them.
Outputs of the test : One set of the results for each WAN link configured on the target PacketShaper Load Balancer that is being monitored.
