e2e measurements
Hi all,
These are questions out of curiosity though might not fit with the psamp goals
1)I am was always wondering about e2e peformance measurement since it is difficult to measure ..This is extremely important at times of service degradation in the network and hence a strong need for e2e service assesement.On random browsing about ways various ISP's measurement strategies,they tend to describe and measure service from a network view .Is their any research on e2e measurements.
2)Are the selection of internet performance metrics done from end-user perspective (from which cutomers know what performance to expect).Does netscope take end-user persecptive while selecting a metric ?
3) This is a question more related to psamp & e2e measurement.Its a well known fact that TCP packets can give e2e measurement and hence can be useful to study the service degradation from end user's persecptive.Also,TCP give us lot of avenues for aggregation (packet size + time stamp pushes me to think of various levels of granularity in aggregation).My question is *will these details give me a clear picture of service quality from a customer point of view ( unlike a network persecpctive )*
4) Is there ways to measure overbooking by service providers.I know there is a way using ping but will not work for high-speed links and also mostly concentrate on round trip than one way (which will be more useful)
5) which gives more info on e2e details ( packet measurements or flow measurements) ..psamp or ipfix :-)
Thanks in advance ,
