Advanced Policy Routing in FatPipe Version 7

FatPipe has recently begun shipping version 7.1.1.  As part of this new release, FatPipe has enhanced policy routing.  A new policy route feature is Threshold Based Session Failover.

With Threshold based session failover, the FatPipe appliance actively checks the quality of the connection of each of the lines selected.  Latency, jitter, and packet loss are measured for each WAN interface that has the “watch parameters” check box selected.

Within outbound policies a rule can now be created that will allow specified traffic fail off of specified connections once threshold are exceeded.  This allows the end user to configure the FatPipe to move traffic off of a WAN connection as the link degrades.  Thresholds can be set by Latency (in ms), Jitter (in ms), and Packet Loss (in percentage).  Once a threshold is exceeded, traffic that adheres to the policy route will treat this WAN connection as failed even if the connection passes a route test.  Traffic that does not adhere to the policy route will continue to use the WAN connection provided the connection continues to pass the route test.  The FatPipe will continue to monitor the watched parameters and once the connection quality improves and meets the thresholds sessions will be routed out the original WAN interface.

FatPipe threshold based session failover is graceful meaning session will continue on the WAN interface they are established.  Only new sessions will be established on the failed over and failed back WAN interface, existing sessions will not be terminated as a result of threshold based session failover.
