Research ArticleOpen accessIn the abstractAn Approach to Improve the State Scalability of Source Specific MulticastS. A. Al-Talib, B. M. Ali, S. KhatunProblem statement: Source Specific Multicast (SSM) is an acceptable solution for current multicast applications; since the driving applications to date are one to many, including Internet TV, distance learning, file distribution and streaming media. Approach: It was useful for billing, address allocation and security. SSM still had serious state scalability problem when there were a large number of simultaneous on-going … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 6,820 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Active Queue Management TechniquesT. B. Reddy, A. AhammedCongestion is an important issue which researchers focus on in the Transmission Control Protocol (TCP) network environment. To keep the stability of the whole network, congestion control algorithms have been extensively studied. Queue management method employed by the routers is one of the important issues in the congestion control study. Active Queue Management (AQM) has been proposed as a router-based … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti Directional Geographical Traceback with n Directions GeneralizationS. Karthik, V. P. Arunachalam, T. RavichandranProblem Statement: Denial of Service/Distributed Denial of Service (DoS/DDoS) attacks deny regular, internet services from being accessed by legitimate users, either by blocking the services completely, or by disturbing it completely, so as to cause customer baulking. Approach: Several traceback schemes were available to mitigate these attacks. Directional geographical traceback8 (DGT8), directional geographical trackback scheme, with 8 directions was one … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 7,010 accessesView PDFCite
Research ArticleOpen accessIn the abstractProvisioning QoS in Virtual Private Network using Dynamic SchedulingR. Ravi, S. RadhakrishnanActive and programmable networks change the functionality of routers and switches by using VPN endpoints and active packets. The authors present a new packet scheduling scheme called active scheduling to control and maintain QoS parameters in virtual private networks (VPNs) within the confines of adaptive and programmable networks. In active scheduling a VPN endpoint on the router monitors the accumulated … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,730 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Packet Marketing Method in DDoS Attack DetectionChanghyun Beak, Junaid Ahsenali Chaudhry, Keonsoo Lee et al.Functionality and availability are one of the main characteristics of internet and hence very inviting for attackers to try to provoke a denial-of-service attack. As the intensity and frequency of DDoS attacks has increased, various preventive mechanisms have also been proposed. One of the most effective defence mechanisms proposed was Path Identification (Pi). This method tracks the packet transmission path. … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,076 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Resource Reservation ProtocolDesire Oulai, Steven Chamberland, Samuel PierreThe classical resource reservation protocol (RSVP) is a flow-based signaling protocol used for reserving resources in the network for a given session. RSVP maintains state information for each reservation at every router along the path. Even though this protocol is very popular, he has some weaknesses. Indeed, RSVP does not include a bidirectional reservation process and it requires refresh messages … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,488 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of an Input Queuing Packet SwitchAzeddine Bilami, Mustapha Lalam, Mohamed BenmohammedMany Architectures of Internet routers, ATM and Ethernet switches have been proposed and analysed in literature. Theoretically reliable and valid solutions have been developed to achieve high performances, but a lot of them are not feasible in practice for commercial and technological reasons. Few papers develop the implementation and simulation aspects. The objective of this study is the design of … …Journal of Computer Science, Vol. 1, Issue 3 · 19 Sep 2005 · 6,926 accessesView PDFCite
