TCP Implementations and False Time Out Detection in OBS Networks

Tags:
tcp - ip

Overview This paper compares Reno, New-Reno and Selective Acknowledgements (SACK), the three most common TCP implementations today in (future) optical burst switched (OBS) networks. In general, SACK, which considers multiple Triple Duplicated ACKed (TD) losses in one round, is found to perform best in OBS networks, while New-Reno, which improves Reno in packet switched networks by fast retransmission in responding to partial ACKs, may however perform worse than Reno. All three TCP implementations react to a Time Out (TO) loss in the same way (i.e. using Slow Start).

Has Gigabit Ethernet come of age?

In short, this pipe is fat, fast and cheap, leading to rumors that it may be the packet protocol to push Asynchronous Transfer Mode (ATM) and its circuit-switched cronies out of their exclusive oasis they call the WAN.

Key internet server gets relocated for security reasons - further details

Many of the tasks performed by the root servers are duplicated elsewhere, meaning that even if a successful attack took down all 13 servers at once, the net would probably not be shut down, Tuton said.

RIM results make waves

This compares with a GAAP net loss of $8.3 million, or 83 cents per share, for the same period a year ago. It also earned $16.3 million, or 20 cents a share, for the quarter, compared with a loss of $92.8 million, or $1.21 a share, in the year...

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
