Determining WAN Characteristics

To correctly configure an FCIP route for maximum performance and reliability

requires precise understanding of the IP link (WAN) characteristics, including the

following link characteristics:

Link RTT

Link data rate end-to-end:

Available link bandwidth

Allocated link bandwidth

Link (WAN) quality: congestion (dropped packets) and packet errors

Local Router Remote Router

LAN/WAN

Fibre Channel Switch

Local Storage Array

Remote Server
