Cloud computing is gaining in popularity. At the same time, the global community is becoming increasingly conscious about sustainability. While intuitively Cloud computing, due to resource consolidation and virtualization, economies of large scale, delivery on demand, etc., has the potential to be more sustainable than well tuned data centers, this is not guaranteed. To evaluate and understand Cloud...
Network device vendors have recently opened up the processing capabilities on their hardware platform to support third-party applications. In this paper, we explore the requirements and overheads associated with co-locating middlebox functionality on such computing resources on networking hardware. In particular, we use an example of TCP acceleration proxy (CHART) that improves throughput over networks...
With the ever growing size of the Internet and increasing popularity of the overlay and peer-to-peer networks, scalable end-to-end (e2e) network monitoring is essential for better network management and application performance. For large scale networks, an e2e monitoring infrastructure should minimize the measurement cost while ensuring that the network is still monitored at fine enough time-scales...
Multihomed, mobile wireless computing and communication devices can spontaneously form communities to logically combine and share the bandwidth of each other's wide-area communication links using inverse multiplexing. But, membership in such a community can be highly dynamic, as devices and their associated WWAN links randomly join and leave the community. We identify the issues and trade-offs faced...
