The Weekly Round-Up: 01.05.09
Round-Up Frankly you should probably sack the two-thirds that said they wouldn't steal the data, just for lacking imagination. Still, before you rush out and sack a third of your staff at random on the off-chance... [01 May 2009]
Credit crunch sees UK firms send techies to cops
News There are some instances where a business experiences a drop but does not want to sack a member of staff and as a result they could be more willing to send them off for secondment for a period of time until things pick... [19 Jan 2009]
Design, Implementation and Evaluation of a QoS-Aware Transport Protocol
White Paper QSTP combines QoS-aware TFRC congestion control mechanism, which takes into account the network-level bandwidth reservations, with a Selective ACKnowledgment (SACK) mechanism in order to provide a QoS-aware transport... [04 Aug 2008]
Podcast: The Weekly Round-Up 04.04.08
Round-Up Podcast Brits suffering IT low self-esteem, the laptop scam, mobile dangers and nomo-phobia are the hot topics discussed in this week's Weekly Round-Up podcast. Andy McCue hosts and is joined in the studio by Julian Goldsmith, Tim Ferguson and... [04 Apr 2008]
Editor's Blog: Ever tried to sack a CIO?
Comment His claim: of all the senior managers in a business, the CIO is the least likely to get the sack. HR directors, of course, can be judged on the number of people they sack and the quantities of pointless... [06 Mar 2008]
New Reno and SACK TCP Implemented in UMTS Networks: A Performance Analysis
White Paper In this paper the performances of two TCP variants are evaluated and compared, namely TCP New Reno and TCP SACK. Universal Mobile Telecommunication System shortly UMTS is seen as the future mobile network. [27 Dec 2007]
Multiple Layer Error Control Over Wireless Links
White Paper This paper compares the wireless performance of TCP with or without selective acknowledgments and in the presence or absence of a reliable link layer protocol, in order to determine whether link layer error control remains beneficial for... [27 Dec 2007]
A Uni?ed Framework for Modeling TCP-Vegas, TCP-SACK, and TCP-Reno
White Paper The framework allows the modeling of multiple variations of TCP, including TCP-Vegas, TCP-SACK, and TCP-Reno, under general network situations. The analysis provided by this framework leads to many interesting... [20 Dec 2007]
OPNET Model of TCP With Adaptive Delay and Loss Response for Broadband GEO Satellite Networks
White Paper It evaluates and compare the performance of TCP-ADaLR, TCP SACK, and TCP NewReno, with and without delayed acknowledgment. Transmission Control Protocol (TCP) provides reliable transport services for Internet applications. [06 Dec 2007]
TCP Westwood Performance Over Multiple Paths
White Paper This paper exposes the side effects of the multiple path deployment on TCP Reno and SACK performance, and contrasts its behavior to that of TCP Westwood. Since its first introduction, TCP has been the major facility to... [06 Dec 2007]
M-TCP+: Using Disconnection Feedback to Improve Performance of TCP in Wired/Wireless Networks
White Paper The paper compares the performance of the MTCP+ algorithm with the performance of M-TCP, TCP NewReno, and TCP SACK in both the absence and the presence of disconnections for a file transfer protocol (download) application. [06 Dec 2007]
C-Snoop: Cross Layer Approach to Improving TCP Performance Over Wired and Wireless Networks
White Paper Of those solutions, the localized link layer schemes, such as Snoop, SACK-Aware-Snoop and SNACK, has been shown to be the most effective. TCP continues to be the most important transport layer communication protocol. [06 Dec 2007]
Simulation-Based Comparisons of Tahoe, Reno, and SACK TCP
White Paper This paper uses simulations to explore the benefits of adding Selective ACKnowledgments (SACK) and selective repeat to TCP. The first version is New-Reno TCP, a modified version of TCP without SACK that... [31 Oct 2007]
TCP Pacing Revisited
White Paper It was found that pacing primarily has three effects: reduced burstiness of traffic, increased synchronization among the rows and fragmented SACK blocks in a flow. The paper analysis how these factors play out for... [31 Oct 2007]
An Analysis of TCP Through Simulation
White Paper The TCP variants analyzed were TCP Reno, TCP New Reno, TCP Vegas, and TCP SACK. This paper is an analysis of TCP and its variations through the use of simulations. The NS-2 network simulator was used to help understand... [31 Oct 2007]
