A distributed application running on top of such network may contain thousands of sites belonging to different logical nodes with the transport channels between them extending through multiple domain boundaries and crossing multiple hierarchical levels. While knowledge of causality between the events in such a system is essential for analyzing the system behavior and ensuring the correct operation through solving various problems related to mutual exclusion, consistency maintenance, fault tolerance and recovery, etc., the accurate tracking of the causality information may be infeasible due to the system's size and lifespan. For example, the communication and storage overhead involved in using the conventional vector clock, which allows causality to be completely characterized, is linear in the number of sites of a distributed system. In this paper we propose a new logical time system, called hierarchical vector clock or HVC, which allows causality to be detected between events in a large distributed system with a high degree of accuracy, while being ideally suited for the hierarchical structure of an underlying network and able to scale gracefully with the increasing number of distributed sites.","PeriodicalId":370762,"journal":{"name":"1999 2nd International Conference on ATM.

In particular, the undertaken work has assumed simultaneous ABR connections in the presence of competitive traffic in the network. More precisely, we have (a) evaluated the performance of multiple ABR connections end-to-end, using both the explicit forward congestion indication (EFCI) and explicit rate (ER) mechanisms, (b) studied the adaptation of the ABR sources under the presence of competitive traffic in the network by applying a dynamic fairness scheme and, (c) studied the dynamics and performance of the TCP/IP protocol over the ABR service specified for an ATM network. Moreover, the performance improvement of TCP over ABR, using an \"interworking\" function between the TCP end-to-end flow control and the ABR rate-based control as well as examine the effect of the \"use-it-or-lose-it\" function, is considered. Furthermore, the different levels of performance are compared so as to select the optimum values for mandatory ABR service parameters, being the maximum number of cells (Nrm) between two successive resource management (RM) cells and the factors controlling the increase/decrease of the cell transmission rate (RIF: rate increase factor, RDF: rate decrease factor). Finally, the concept of a dynamic UPC mechanism that monitors the ABR traffic contract is identified.","PeriodicalId":370762,"journal":{"name":"1999 2nd International Conference on ATM.

By splitting the traffic of a small number of virtual connections into subconnections over multiple low-capacity core switch ports, SCIMA achieves a performance level comparable with that of an equivalent high-capacity port switch. The scheme ensures that each split cell flow is re-assembled and delivered in the original order even in the presence of variable differential delays and highly non-uniform switching path usage. Furthermore, it can seamlessly recover from isolated cell losses within the core switch, as well as detect the loss of a certain number of consecutive cells belonging to the same subconnection. However, it is unable to restore, by itself, the re-assembly cell chain after two or more consecutive cell losses occur in a row on the same subconnection, and has to rely on other recovery means. In this paper, we describe a fault tolerance mechanism called advanced frame recovery, which applies the concept of framing in the asynchronous environment of SCIMA by inserting regular, albeit not necessarily periodic, checkpoints into the split cell flow. When the mechanism is invoked, it discards some of the successfully delivered cells and allows us to restart the chain at a subsequent checkpoint. The advanced frame recovery scheme is used when SCIMA detects consecutive cell losses within the same subconnection; it also serves as an additional measure of integrity checking during regular re-assembly to correct certain vulnerabilities of SCIMA. We present the motivation and implementation details of advanced frame recovery, together with a discussion of the trade-offs of such an open loop (as opposed to feedback driven) sequence control scheme.","PeriodicalId":370762,"journal":{"name":"1999 2nd International Conference on ATM.
