However, such an approach faces many challenges: (a) distributing the attack hinders detection; (b) defense systems must guarantee good service to legitimate traffic during the attack; and (c) deployment costs and false alarm levels must be sufficiently small and effectiveness must be high to provide deployment incentive. We discuss each of the challenges and describe one successful design of a source-end DDoS defense system-the D-WARD system. D-WARD was implemented in a Linux router. We include experimental results to illustrate D-WARD's performance.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.

Often, the redirection of a client browser towards a given replica of a Web page has to be explicit and is performed after the client's request has reached the Web server storing the requested page. As an alternative, we propose to perform the redirection as close to the client as possible in a fully distributed manner Distributed redirection ensures that we find a replica wherever it is stored and that the closest possible replica is always found first. By exploiting locality, we can keep latency low.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.

The mechanism relies on periodic refresh messages between routers to maintain the reservation states (soft-state approach). Because of the loss of tunnel RSVP messages, the mechanism presents a very long latency at reservation establishment. The problem reduces the performance of multimedia applications. We report the use of staged refresh timers in the aggregation mechanism at the set-up procedure of the resource reservation. The simulation results show a significant decrease of the establishment time of multicast sessions.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.

We believe that one reason for this is the lack of standardisation of group communication system interfaces. The paper proposes an architecture, using the standard decomposition into services, where services are based on standard interfaces: both interactions between services and interactions with the application use existing, open standards. A decomposition of the group communication into services is presented, along with a description of applicable standards. As an example, a group membership service based on the LDAP standard is discussed.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.

Cache cooperation is often carried out through purely hierarchical and flat schemes that suffer from scalability problems when the number of servers increases. We propose, implement and compare the performance of three novel distributed cooperation models based on a two-tier organization of the cache servers. The experimental results show that the proposed architectures are effective in supporting cooperative document lookup and download They guarantee cache hit rates comparable to those of the most performing protocols with a significant reduction of the cooperation overhead Moreover in case of congested network, they reduce the 90-percentile of the system response time up to nearly 30% with respect to the best pure cooperation mechanisms.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.
