Packet Order Correction

PACKET ORDER CORRECTION technology provides the capability to keep track of the order of sent packets and rearrange the out-of-order packets on the target WAN optimizer before sending them forward. When packets are lost during replication, retransmission increases, putting a strain on performance and throughput. By tagging the packets and reordering them performance can be maintained. Even though network routers intrinsically handle out-of-order packets on the IP level, the best practice for situations where replication is affected would be to provide this feature on the ingress/egress points on the WAN by using WAN optimizers. Done in real time, these types of features are really important to Symmetrix replication and provide the capability for more data to be moved onto the LAN at immediate speeds locally before and after the data was optimized during the WAN transmission.
