- UFO: A Resilient Layered Routing Architecture
- Conventional wisdom has held that routing protocols cannot achieve both scalability and high availability. Despite scaling rather well, today's Internet routing system does not react quickly to changing network conditions. Overlay networks, on the other hand, can respond quickly to changing network conditions, but their reliance on aggressive probing does...

- Link-State Routing With Hop-by-Hop Forwarding Can Achieve Optimal Traffic Engineering
- Link-state routing with hop-by-hop forwarding is widely used in the Internet today. The current versions of these protocols, like OSPF, split traffic evenly over shortest paths based on link weights. However, optimizing the link weights for OSPF to the offered traffic is an NP-hard problem, and even the best setting...

- On Survivable Access Network Design: Complexity and Algorithms
- With economic constraints and limited routing capability, the structure of an access network is typically a "fat tree", where the terminal has to relay the traffic from another terminal of the same or higher level. New graph theory problems naturally arise from such features of access network models, different from...

- Revisiting Ethernet: Plug-and-Play Made Scalable and Efficient
- Because Ethernet bridging does not scale, most enterprise networks consist of small Ethernet-based subnets interconnected by IP routers. Although Ethernet's flat addressing and transparent bridging allow each subnet to run with minimal configuration, interconnecting subnets at the IP level introduces significant management overhead that increases with the size of the...

- HEAT: Scalable Routing in Wireless Mesh Networks Using Temperature Fields
- Existing unicast routing protocols like for example AODV are not suited well for wireless mesh networks as in such networks, most traffic flows between a large number of mobile nodes and a few access points with Internet connectivity. This paper proposes HEAT, an anycast routing protocol for this type of...

- Optimal Scheduling for OFDMA Systems
- This paper considers a scheduling and resource allocation problem for the downlink of an OFDMA-based wireless network, where the channel estimation error is modeled by a self-noise term in the decoding process. During each time-slot this involves selecting a subset of users for transmission, determining the assignment of available subcarriers...

- Evolving Toward a Self-Managing Network
- Why is network management so difficult? The authors think the complexity of the individual network elements is a big part of the problem, and a big barrier to fundamental change. Nowadays routers implement numerous routing protocols (e.g., BGP, OSPF, IS-IS, EIGRP, and RIP) and data-plane mechanisms (e.g., class-based queuing, RED,...
