SUMMARY IP multicast technology is highly advantageous for various applications and future needs in the Internet. Yet, it is generally recognized that the IP multicast routing protocol is fairly complex and non-scalable and requires additional maintenance and operational cost to network administrators. Although there has been much research related to IP(More)
In this study, we present the flexible arrays of inexpensive network (FAIN) architecture: it can be used to maximize parallelism in network systems in order to satisfy future Internet traffic growth. Although the "parallel-in-global" approach used in FAIN overcomes a constraints of serial interfaces, the performance of applications with s small stream can(More)
Links with high bandwidth ranging from 1 to 10 Gbps are increasingly in use worldwide. Congestion control with the positive use of router feedback that explicitly indicates network conditions is a promising way to address the performance issues of congestion control especially in such high-speed networks. In this paper, we propose SIRENS, a scalable,(More)
Networks operating at 1 Gbit/s, 10 Gbit/s or even 100 Gbit/s and spanning several countries or states are now becoming commonplace. More and more users have to transfer routinely between mul-ti-GB and multi-TB datasets over these gigabit networks. There is a growing range of application domains for such massive transfers including data-intensive Grids(More)
