The previous surveys show that more than 90% of the flows in typical data center networks are smaller than 100KB in size, while most bytes transmitted are from a few large flows. The small flows are usually sensitive to their completion times while the large flows require a high throughput. The previous works usually either achieve low completion times for small flows or high throughput for large...
Imbalanced load distribution among multiple APs (access points) has become a serious problem in enterprise WLANs. Load imbalance causes inefficiency of network usage and unreasonable resource allocation. We find that users tend to come and leave together, which can lead to fluctuation of network load. We propose a novel online AP allocation scheme (ASC) to keep load balanced when users come and leave...
Long-haul traffic accounts for a large percentage of the total data carried on the Internet. Due to the rapid changes of the Internet in terms of access technologies and core network bandwidth, the performance of long-haul transmission in the current Internet environment has not been well understood. In our research, we chose three typical long-haul paths (national, international yet continental,...
