Introduction:
WanMan is intended to give the network administrator a visual view of how their corporate WAN bandwidth is getting utilized. In addition to online monitoring the WAN link, WanMan also facilitates the network administrator to keep record of WAN usage. WanMan is based on SNMP (Simple Network Management Protocol) accepted across industry for management of computer networks.
In a Cisco® router with IP accounting and SNMP enabled, the router will monitor the data on its WAN port. But the data displayed by the router will be raw and will be of little use to a network manager who wants to know the traffic on WAN link based on Source IP address, Destination IP address and Number of packets transmitted. WanMan takes this raw data and displays it in a user friendly format based on Source IP Address, Destination IP address, Number of packets & bytes transmitted and number of violations.
