The size of router forwarding tables is a critical aspect of the quality of a network design. Oversized forwarding tables not only force enterprises to purchase expensive hardware, which is a significant operational cost, but also make issues such as power consumption and heat generation more prominent. The size of forwarding tables is a direct result of the IP prefix assignment scheme. Unfortunately,...
Recent works [1], [2] have shown the benefits of a systematic approach to designing enterprise networks. However, these works are limited to the design of greenfield (newly deployed) networks, or to incremental evolution of existing networks without altering prior design decisions. In this paper, we focus on redesigning existing networks, allowing for changes to existing decisions. Such redesign (migration)...
The goal of enabling ubiquitous video broadcasting on the Internet has been a long cherished vision in the networking community. Prior efforts aimed at achieving this goal based on the IP Multicast architecture have been unsuccessful. In recent years, peer-to-peer (P2P) streaming has emerged as a promising alternative technology, which has matured to the point that there are several commercial offerings...
Most prior work on the use of key management algorithms to enable confidentiality of video delivery has been conducted in the context of IP Multicast. In this paper, we consider the unique challenges and opportunities of integrating key management algorithms in an overlay multicast system. We conduct a systematic and extensive performance evaluation of strategies for key dissemination in the context...
