With Veritas Volume Replicator (VVR), one commonly misdiagnosed problem is an issue with a operating system's network configuration that is mistaken to be an issue with VVR due to replication being slow. To avoid this misdiagnosis, you must be familiar with issues related to network configurations and methods for determining if the issue is with VVR or if the issue is instead with the network.
Packet reordering is the inverting of packets during the tramission of data across a network, which causes the TCP receiver to believe that packets are missing. Packet reordering can occur due to multi-path routing, and slows down data transmission due to the TCP receiver requesting the sender to resend packets, which uses more bandwidth when the packets are resent.
