The QoS routing feature is important for a mobile network to interconnect wired networks with QoS support (e.g., ATM, Internet, etc.). The QoS routing protocol can also work in a stand-alone mobile ad hoc network for real-time applications. Under such a routing protocol, the source (or the ATM gateway) is informed of the bandwidth and QoS available to any destination in the mobile network. This knowledge enables the establishment of QoS connections within the mobile network and the efficient support of real time applications. In addition, it enables more efficient call admission control. In case of ATM interconnection, the bandwidth information can be used to carry out intelligent handoff between ATM gateways and/or to extend the ATM virtual circuit service to the mobile network with possible renegotiation of QoS parameters at the gateway. Simulation results suggest distinct performance advantages of our protocol calculating the bandwidth information. It is particularly useful in call admission control. Furthermore, \"on-demand\" routing enhances the performance in the mobile environment because the source can keep more connectivity to a receiver in the path-finding duration. Simulation experiments show this improvement.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

As the Internet becomes a common transport vehicle for various applications, some of them require a new flow control different from TCP since they do not need the expensive error recovery inseparable from the current TCP. The new flow control algorithm for real-time applications should efficiently utilize network bandwidth and also minimize the delay jitter while not hampering the performance of the existing TCP applications. This paper introduces a flow control algorithm which dynamically adjusts the sending rate similarly to TCP based on the network status evaluated by two network parameters; packet loss and round trip time (RTT) reported by RTP/RTCP. For the reduction of delay jitters, the algorithm tries to maintain RTTs periodically reported by RTCP within a predetermined range by either additively increasing or multiplicatively decreasing the sending rate as much aggressively as TCP. For evaluation, we compare the behavior of our algorithm to that of RAP, one of representative flow control algorithms for real-time applications. The simulation experiments show that our algorithm achieves the same degree of performance for TCP as RAP but without overloading the network with ack packets like RAP.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

Our purpose in this article was twofold. First, we reviewed GSM, HSCSD (high speed circuit switched data), GPRS and EDGE (enhanced data rate for GSM evolution). Second, the performance of the packet random access channel (PRACH) was analyzed with respect to quality of service parameters: network access delay, throughput, and failure probability. We derived the overall GPRS traffic channel utilization as a function of the throughput and channel holding time. EDGE introduction will decrease the holding time of GPRS terminals due to multilevel encoding and result in higher throughput. Thus, in order to maintain GPRS channel efficiency, PRACH efficiency must be boosted. Thus packet-capturing is introduced to offset access collisions on (P)RACH and increase its efficiency. We noted that the capture effect decreases with access throughput contrary to access delay and failure rate. These QoS parameters are indicative of network performance, hence crucial for novel network planning.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

On the one hand, manual configuration of a large amount of firewalls distributed in many access points can not meet the global security requirements in the open and dynamic environment. On the other hand, the ordinal lookup of filtering rules in each individual firewall results in great decrease of throughput. Aimed at a typical transit network and its security policy requirements, a policy-based access control framework (PACF) is proposed. This framework is based on three levels of abstract access control policy: organizational access control policy (OACP), global access control policy (GACP) and local access control policy (LACP). The GACP, which comes from the results of IDSes and search engines according to OACP, is automatically and dynamically distributed to firewalls as LACPs. Each LACP is then enforced by an individual firewall. Some key algorithms for distribution of GACP and enforcement of LACP are described. A hash-based algorithm is proposed, for lookup of filtering rules in LACP. Under an environment with policy requirements described in this paper the new algorithm reduces the time complexity of lookup from O(N) of the traditional sequential algorithm to O(1), which therefore increases largely the throughput of firewalls.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).
