Douskalis, 2000) is not appropriate for non-QoS networks, which are the majority of networks in the Internet. It is therefore difficult to guarantee QoS for a VoIP over Virtual Private Networks (VPNs) environment (M. Gunter et al., 1999; Yoshihiro Ito et al., 1998). The paper presents an idea which will alleviate such a limit. The proposed idea is to use a dial up line as an additional connection to elevate degrading bandwidth performance, due to the unreliability of the Internet. However, existing load balancing tools implemented on the router are not appropriate for implementation over a VPN environment. Therefore, the authors propose application routing load balancing (ARLB) for a VPN environment.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.

Our approach defines a logistical session layer (LSL) that uses intermediate process-level \"depots\" along the network route from source to sink to implement an end-to-end communication session. Despite the additional processing overhead resulting from TCP/IP protocol stack-Unix kernel boundary traversals at each depot, our experiments show that dramatic end-to-end bandwidth improvements are possible. We also describe a prototype implementation of LSL that does not require any Unix kernel modification or root access privilege, which we used to generate the results, and we discuss its utility in the context of extant TCP/IP tuning methodologies.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.

The GDN takes a novel, optimistic approach to stop the illegal distribution of copyrighted and illicit material via the network. Instead of having moderators check the software archives at upload time, illegal content is removed and its uploader's access to the network permanently revoked only when the content is discovered. An important feature of the GDN is that the objects containing the software can run on untrustworthy servers. A first version of the GDN has been implemented and has been running since October 2000 across four European sites.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.

RapidIO is a 10-Gb/s, low-latency packet-switched interconnect technology designed for processor-to-processor, processor-to-memory, and processor-to-peripheral interconnects. Two network topologies were simulated, a simple network consisting of an 8-port switch and eight processing nodes and a more extensive network consisting of five 8-port switches and 24 processing nodes. The results indicate that latencies as low as 92 ns for a remote 64-bit read request/response transaction may be achieved in an unloaded single-switch system. The effectiveness of various flow control mechanisms provided by the protocol are also explored, and when used in combination, a 10% increase in link utilization is achieved.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.

Computer networks are becoming increasingly common, and are used in sensitive applications in which serious damage could be done by a network failure. There is a need for design principles that would enable a new generation of solutions having the required properties. Needed are technologies that would be inherently robust, provably scalable, and sufficiently self-organizing to adapt as conditions change in the network. The Spinglass project has been successful in solving an important class of such problems. At the core of our work is a new style of gossip-based communication protocol. We are using this protocol in support of a variety of systems programming tools. The article discusses two of them: Bimodal Multicast, a scalable reliable multicast protocol having probabilistic reliability properties, and Astrolabe, a virtual distributed database constructed entirely through peer-to-peer interactions among the components of a large system. Both technologies are shown to be stable under stress, arbitrarily scalable without growth in communication or processing loads, and to have real-time properties.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.

We present a new approach of building micro-firewalls on network hosts to enable distributed intrusion detection with dynamic policy change, as the threat pattern changes. This distributed security can effectively counteract attacks from intruders or insiders. Three policy-update mechanisms are evaluated for achieving dynamic security. Mobile agents are shown most scalable and robust for policy update, but prone to attacks by other agents or hosts. The CORBA has the best speed performance with lower overhead The Java-based RMI demonstrates the highest security based on the sandbox model. The optimal choice depends on the tradeoffs among operating speed, Intranet scalability, host robustness, and the security level demanded by specific network applications.","PeriodicalId":385607,"journal":{"name":"Proceedings IEEE International Symposium on Network Computing and Applications.
