Ulysses: a robust, low-diameter, low-latency peer-to-peer network

11th IEEE International Conference on Network Protocols, 2003. Proceedings., 2003

In this paper, we present Ulysses, a peer-to-peer network based on the butterfly topology that achieves the theoretical lower bound of log n/ log log n on network diameter when the average routing table size at nodes is no more than log n. Compared to existing DHT-based schemes with similar routing table size, Ulysses reduces the network diameter by a factor of log log n, which is 2–4 for typical configurations. This translates into the same amount of reduction on query latency and average traffic per link/node. In addition, Ulysses maintains the same level of robustness in terms of routing in the face of faults and recovering from graceful/ungraceful joins and departures, as provided by existing DHT-based schemes. The performance of the protocol has been evaluated using both analysis and simulation. Copyright © 2004 AEI

Bowman: a node OS for active networks

The packet processing path implemented in Bowman incorporates an efficient and flexible packet classification algorithm, supports multi-threaded per-flow processing, and utilizes real-time processor schedulingto achieve deterministic performance in userspace. In this paper we describe the design and implementation of Bowman; discuss the support that Bowman provides for implementing execution environments for active networking; discuss the network-level architecture of Bowman that can be used to implement virtual networks; and present performance data. Bowman is able to sustain 100 Mbps throughput while forwarding IP packets over fast Ethernets.

It has been used by networking researchers in a variety of ways, most often to create topologies for use in simulation studies. This paper describes the features of a new release of GT-ITM, including enhanced visualization capabilities; a routing and forwarding module for use with large graphs; and support for modeling of interdomain routing policies.

Active networks will allow rapid deployment of new and complex network services. An important property of an active network API is the support it provides for composing complex services out of components. An efficient
