In order to meet their stringent dependability requirements, most modern packet-switched
communication networks support fast-recovery mechanisms in the data plane. While …

Traffic engineering is an important mechanism for Internet network providers seeking to
optimize network performance and traffic delivery. Routing optimization plays a key role in …

We present a decade of evolution and production experience with Jupiter datacenter
network fabrics. In this period Jupiter has delivered 5x higher speed and capacity, 30 …

Exponential bandwidth scaling has been a fundamental driver of the growth and popularity
of the Internet. However, increases in bandwidth have been accompanied by increases in …

As peer-to-peer (P2P) emerges as a major paradigm for scalable network application
design, it also exposes significant new challenges in achieving efficient and fair utilization of …

Networks are expected to provide reliable performance under a wide range of operating
conditions, but existing traffic engineering (TE) solutions optimize for performance or …

Current intra-domain Traffic Engineering (TE) relies on offline methods, which use long term
average traffic demands. It cannot react to realtime traffic changes caused by BGP reroutes …

Hierarchical graph decompositions play an important role in the design of approximation
and online algorithms for graph problems. This is mainly due to the fact that the results …

Faults such as link failures and high switch configuration delays can cause heavy
congestion and packet loss. Because it takes time to detect and react to faults, these …

Current network infrastructures exhibit poor power efficiency, running network devices at full
capacity all the time regardless of the traffic demand and distribution over the network. Most …
