Tools - Development
management station to be installed at STAR TAP– http://www.accumatics.com– dual boot
Accumatics OC3mon via LS1010 VC snoop custom performance/measurements environment
– mping, ttcp, pathchar, traceroute server, treno, netperf...

Tools - Development
TACACS access control to routers and switches– rights controls for NOC, local and peer network engineers– logs configuration changes
22 June 1999 STAR TAP International Advisory Committee Meeting
7
Tools - Development
configuration management tools– archiving of router/switch configurations– automated differences report of router/switch configurations
22 June 1999 STAR TAP International Advisory Committee Meeting
8
Tools - Development
command proxy for routers and switches– web-based mechanism to submit a query to a router or
switch and view the query results– length of request string limited– number of queries per device per unit time limited– limited to only certain commands– the mechanism logs into the target device using a non-
enabled username/password, sets term length to zero, executes the command and displays the result

Tools - Development
network traffic/errors map– collect SNMP-based stats of utilization and interface errors– display in gracphical map
colors according to utilization errors as a logarithmic scale hash mark, with dampened decay
– time-based playback of graphs

Asia-Pacific Advanced Network (APAN)
An international consortium established in June 1997 to promote advanced research in networking technologies and the development of high-performance broadband applications and infrastructure in the Asia-Pacific region.
Four primary members: Australia, Japan, Korea and Singapore.
Associate and other members: Malaysia, Hong Kong, Indonesia, Thailand and Philippines.

TransPAC Network
IPv4, native IPv6 and ATM services based on a 73Mbps VBR-nrt ATM connection from the APAN Tokyo exchange point to the STAR TAP in Chicago.
The original 35Mbps service was upgraded to 73Mbps in March of 1999.
Multicast is supported (although some problems)
The underlying ATM service is provided by AT&T and Kokusai Denshin Denwa Co., Ltd.
