Effort:
Negligible for remote hosts
Monitoring host: < 1 day to install and configure,
occasional updates to remote host
tables and problem response
Archive host: 20% FTE, code stable, could do with
upgrade, contact monitoring sites
whose data is inaccessible
Analysis: your decision, usually for long term details
download & use Excel
Trouble-shooting:
usually re-active, user reports, then look at PingER
data
have played with automating alerts, data will/is
available via web services
Ping blocking
Complete block easy to ID, then contact site to try and
by-pass, can be frustrating
for 3rd world
Partial blocks trickier, compare with synack
Derived throughputs poor for well connected sites
(<0.1% loss)
Funding
Unfortunately, network management research has
historically been very under-funded,
because it is difficult to get funding bodies to recognize this as legitimate networking research.
