Problem: Load Sharing - High out of Sequence Rate
Load sharing devices attempt to maximize the use of bandwidth by spreading traffic over several different routes. If the delay on each route differs by more than 20 milliseconds this can lead to a constant high rate of out of order packets.
Impact
Some Voice over IP systems discard out of order packets, which would cause severe degradation in call quality. All Voice over IP systems would see this condition as a high jitter level. This problem may lead to a constant level of call quality degradation through the call.
Resolution
It is preferable to configure load sharing devices to operate by establishing VoIP calls through consistent routes and to avoid spreading packets from the same call over different paths.
