High-layer protocol and service management based on passive network traffic monitoring: the trace management platform
- Trang 601-608
A fast-growing number of high-layer protocols, services and networked applications has been run over computer networks and needs to be managed. A unified, decentralized framework should be used to scale for the current large and complex computing environments. Besides, the management environment should be quickly and easily adaptable to monitor dynamic scenarios. This paper presents the trace mana......

An architecture for automated replacement of QoS policies
- Trang 796-801
This paper introduces the notion of PoP (policy of policies) used to define standard policy replacement strategies in a policy-based network. We also propose an architecture to support PoP within PDPs (policy decision points originally defined by the IETF). The notion of PoP, and the proposed architecture allow the automation of the policy replacement task currently manually executed by the networ......

Facilitating adaptation to trouble spots in wireless MANs
- Trang 415-420
This paper presents schemes that enable high level communications protocols and applications to adapt to connectivity loss and quality degradation in metropolitan area wireless networks. We postulate that the majority of these problem areas or trouble spots, which are intrinsic to wireless networks, are related to location and environmental factors. Based on this premise, we propose a mechanism th......

Partial path protection for WDM networks: end-to-end recovery using local failure information
- Trang 719-725
We propose a new protection scheme, which we term partial path protection (PPP), to select end-to-end backup paths using local information about network failures. PPP designates a different restoration path for every link failure on each primary path. PPP also allows reuse of operational segments of the original primary path in the protection path. A novel approach used in this paper is that of a ......

Executable test sequence for the protocol control and data flow property with overlapping
- Trang 251-257
We improve an earlier test sequence generation method for testing the conformance of a protocol implementation to its specification modeled by an extended finite state machine (EFSM) represented by a flow digraph. The earlier method produces an executable test sequence (i.e., one that has feasible parameter values) that covers a set of define-clear-use paths of the flow digraph for testing the dat......

Explicit multicast routing algorithms for constrained traffic engineering
- Trang 455-461
This paper presents a new traffic engineering technique for dynamic constrained multicast routing, where the routing request of traffic arrives one-by-one. The objective we adopted is to minimize the maximum of link utilization. Although this traffic engineering is useful to relax the most heavily congested link in the Internet backbone, the total network resources, i.e. sum of link bandwidth cons......

Scheduling real time parallel structure on cluster computing
- Trang 69-74
Scheduling a large number of high performance computing applications on a cluster-computing environment is a complex task. This becomes more critical in real time systems. Efficient scheduling strategies are critically important to achieving good performance. A cluster scheduler without enough knowledge of the state of the cluster and the scheduled tasks cannot adequately manage the cluster resour......

Signalling performance evaluation of large ATM networks based on measurements of isolated switches
- Trang 670-675
In the year 2000 the telecommunication market entered a very deep recession. In the current marketplace the service providers must improve network management to reduce operation costs. ATM network service providers offered mainly permanent virtual circuit connections to customers in the last few years, but recently there is an increasing interest in offering switched virtual circuit (SVC) connecti......

Adaptive explicit congestion notification
- Trang 855-860
Using ns-2 simulations, this paper evaluates an adaptive explicit congestion notification (AECN) router. By receiving round-trip time (RTT) source hints from each TCP flow, AECN divides flows into flow groups based on RTT ranges. AECN uses distinct flow group drop probabilities and a mark front scheme to provide higher goodput and better fairness than random early detection (RED) and explicit cong......

Software supports for preemptive rollback in optimistic parallel simulation on Myrinet clusters
- Trang 617-622
In this paper we present a communication layer for Myrinet based clusters, designed to efficiently support preemptive rollback operations in optimistic parallel simulation. Beyond standard low latency message delivery functionalities, this layer also embeds functionalities for allowing the overlying simulation application to efficiently track whether an incoming message will actually produce causa......
