Proposal for Improving NetworkService Level Shortening of trouble-handling time•Start trouble-handling and announce the information quicklyOperation tools enable us to issue trouble tickets automatically and announceinformation quickly•Shorten trouble-shooting timeRemote trouble-shooting from other areas( cf. Router Proxy on Abilene) World Wide Information sharing•Installation of shared information server providing the followinginformationPerformance and Operation status of networkTrouble and Maintenance information Redundant Network configuration•Redundant configuration is very effective in realizing highavailability. It is desirable that we establish redundantconfiguration as much as possible.Proposal for Improving NetworkService Level Operation of lower layers•For operation, it is very important to check the status of circuitsin cooperation with circuit carriers•As a recent trend, backbone network based on L2 or Lambda isconspicuousLayer2• Difficulty in finding bottle-necks• Apply L3 monitoring technologye.g. ICMP ping, traceroute, other measurement tool• VLAN ID management from end-to-endLambda• Operators can’t monitor and measure performance of circuit/link• Burden for operation on end router/user36
