Routers lose/drop/discard packets for many reasons, most of which QoS tools can do nothing about. This can be resolved by installing the tunnel information to the correct SPU after the request and response packets are processed. Due to softened demand among service providers for its routers and switches, Juniper posted a 6% drop in revenues for the fourth quarter of 2011, and a 33% plunge in earnings. As such "Flow unusable" is used for good number of cases and incrementing the eviction drop also under that leads to issues is debugging. If a packet arrives at the firewall and the difference of the sequence number with the previous packets is larger than the replay window size, then it will be considered as an attack and dropped by the firewall.
