- A Study of End-to-End Web Access Failures
- This paper presents a study of end-to-end web access failures in the Internet. Part of the characterization of failures is based on directly observable end-to-end information. The paper also presents novel analyses that reveal aspects of end-to-end failures that would be hard to discern otherwise. First, it combines end-to-end failure...

- Security and customer service: Why they go hand in hand
- Sometimes, circumventing security is just *bad*.It's true that sometimes an end user circumventing security policies is just someone that feels the IT department is holding him/her back, and that there needs to be some kind of attempt to address the perceived needs of that end user. It's true that...

- Modeling End-to-End Available Bandwidth
- The ability to accurately predict available bandwidth of an end-to-end path is of importance for improving quality of services for end users. For instance, end users can receive high quality video if senders can select to stream video data on an end-to-end path with available bandwidth that fits the required...

- Understanding TCP Over TCP: Effects of TCP Tunneling on End-to-End Throughput and Latency
- TCP tunnel is a technology that aggregates and transfers packets sent between end hosts as a single TCP connection. By using a TCP tunnel, the fairness among aggregated flows can be improved and several protocols can be transparently transmitted through a firewall. Currently, many applications such as SSH, VTun, and...

- Efficient Monitoring of End-to-End Network Properties
- It is often desirable to monitor end-to-end properties, such as loss rates or packet delays, across an entire network. However, active end-to-end measurement in such settings does not scale well, and so complete network-wide measurement quickly becomes infeasible. More efficient measurement strategies are therefore needed. Previous work, examining this problem...

- Measuring End-to-End Bandwidth With Iperf Using Web100
- End-to-end bandwidth estimation tools like Iperf though fairly accurate are intrusive. This paper describes how with an instrumented TCP stack (Web100), one can estimate the end-to-end bandwidth accurately, while consuming significantly less network bandwidth and time. The paper modified Iperf to use Web100 to detect the end of slow-start and...
