Journal ArticleDOI
Optimizing TCP forwarder performance
TL;DR: An optimization technique, called connection splicing, is introduced that can be applied to a TCP forwarder and improves TCP forwarding performance by a factor of two to four, making it competitive with IP router performance on the same hardware.
Journal ArticleDOI
Dynamic adaptation of network connections in mobile environments
TL;DR: The authors present the design of a communication layer for mobile computing that dynamically adapts to changes in network connections, to allow existing TCP/IP based applications to be used in a mobile environment, without application modifications.
Proceedings ArticleDOI
Using idle disks in a cluster as a high-performance storage system
J.S. Hansen,R. Lachaize +1 more
TL;DR: The software support for sharing of disks in clusters, where the disks are distributed across the nodes in the cluster, thereby allowing them to be combined into a high-performance storage system, is described.
Proceedings Article
A scheduling scheme for network saturated NT multiprocessors
J.S. Hansen,Eric Jul +1 more
TL;DR: Performance evaluation of the multiprocessor prototype implementation shows that using a two level network interface servicing scheme that uses interrupts during low network loads to provide low latency and polling threads during high network loads can improve performance when used carefully.
Proceedings ArticleDOI
A distributed shared buffer space for data-intensive applications
R. Lachaize,J.S. Hansen +1 more
TL;DR: This work proposes separating control and data transfer traffic by accessing data through a DSM-like cluster-wide shared buffer space and only including buffer references in the control messages, using a generic API for accessing buffers.
