In order to monitor the one-way delay and packet loss statistics, a delay and
route monitoring tool such ping and traceroute need to be installed on the
T-LAN of the IP Telecommuter site. The delay monitoring tool will be
running continuously, injecting probe packets to each remote subnet or
router/server about every minute. The amount of load generated by this is not
considered significant. At the end of the month, the hours with the highest
one-way delay are noted; within those hours, the packet loss and standard
deviation statistics can be computed.
A target QoS objective for each route from the IP node to a remote subnet (or
router) is set by the customer.
