802.11 (WiFi) networks have become increasingly important for our daily lives. However, previous work has shown that enterprise WiFi performance is often unsatisfactory and that over-utilization and interference from rogue APs are the two primary reasons. To address the above problem, this paper proposes to improve the capacity of WiFi infrastructures by increasing the enterprise AP deployment density,...
Named Data Networking (NDN) is a new Internet architecture that replaces today's focus on where — addresses and hosts — with what — the content that users and applications care about. A unique advantage of NDN over IP is the adaptive forwarding plane, which, by observing the performance of Interest/Data exchange, can dynamically select the best performing forwarding path, detect and recover from failures,...
Load-balanced architectures appear to be a promising way to scale Internet to extra high capacity. However, architectures based on mesh topology have a node-degree of N, which prevents these architectures from large node numbers. This consideration motivates us to study the properties of node degree and its impact on the corresponding load-balanced architectures. In this paper we first show the asymptotically...
The rapid growth of user traffic in the Internet is driving routers to run at increasing bit-rates and have a very large number of ports. However, it is becoming more difficult to just increase the speed of ports. In a router, the centralized switching fabric is the single point of failure (SPF). As the number of line cards increases, the centralized switching fabrics become the bottleneck of the...
