Call admission control algorithms for tandem generalized processor sharing networks
Proceedings - International Symposium on Computers and Communications - - Trang 789-795
P. Barta, R. Nemeth, R. Szabo, J. Biro
This paper proposes several call admission control (CAC) algorithms for tandem networks that employ the generalized processor sharing (GPS) scheduling discipline, and also points out important network issues that are crucial in the design of network level CAC algorithms for GPS. Sessions are considered to be leaky bucket constrained and are regulated by traffic shapers at each network node. The en... hiện toàn bộ

Automatic implementation system of security protocols based on formal description techniques
Proceedings - International Symposium on Computers and Communications - - Trang 355-360
L. Mengual, N. Barcia, E. Jimenez, E. Menasalvas, J. Setien, J. Yaguez
We present an automatic implementation system of security protocols based in formal description techniques. A sufficiently complete and concise formal specification that has allowed us to define the state machine that corresponds to a security protocol has been designed to achieve our goals. This formal specification makes it possible to incorporate in a flexible way the security mechanisms and fu... hiện toàn bộ

An integrated architecture for the scalable delivery of semi-dynamic Web content
Proceedings - International Symposium on Computers and Communications - - Trang 201-206
D. Dolev, O. Mokryn, Y. Shavitt, I. Sukhov
The competition on clients attention requires sites to update their content frequently. As a result, a large percentage of Web pages are semi-dynamic, i.e., change quite often and stay static between changes. The cost of maintaining consistency for such pages discourages caching solutions. We suggest here an integrated architecture for the scalable delivery of frequently changing hot pages. Our sc... hiện toàn bộ

Multicast đáng tin cậy với phản hồi động (DyRAM) Dịch bởi AI
Proceedings - International Symposium on Computers and Communications - - Trang 275-282
M. Maimour, C.D. Pham
Các tính năng mong muốn của multicast đáng tin cậy bao gồm độ trễ đầu cuối thấp, băng thông cao và khả năng mở rộng, và việc đạt được những mục tiêu này không phải là một nhiệm vụ dễ dàng. Chúng tôi đề xuất một giao thức multicast phục hồi cục bộ dựa trên người nhận (người phản hồi) với các người phản hồi động được bầu chọn theo từng gói. Được thiết kế để cung cấp một dịch vụ multicast đáng tin cậ... hiện toàn bộ

An architecture for automated replacement of QoS policies
Proceedings - International Symposium on Computers and Communications - - Trang 796-801
L.Z. Granville, G.A.F. de Sa Coelho, M.J.B. Almeida, L.M.R. Tarouco
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... hiện toàn bộ

Mechanisms to support situated agent systems
Proceedings - International Symposium on Computers and Communications - - Trang 747-752
S. Bandini, F. DePaoli, S. Manzoni, C. Simone
To address the development of complex systems, the definition of novel models that capture their nature and provide developers with abstractions and technologies to both imagine and implement effective solutions is needed. Promising models are those based on multi agent systems, since they naturally capture the concept of independent entities interacting in an environment. This paper presents a mo... hiện toàn bộ

Partial path protection for WDM networks: end-to-end recovery using local failure information
Proceedings - International Symposium on Computers and Communications - - Trang 719-725
Hungjen Wang, E. Modiano, M. Medard
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 ... hiện toàn bộ

Throughput enhancement in wireless ad hoc networks with spatial channels a MAC layer perspective
Proceedings - International Symposium on Computers and Communications - - Trang 421-428
D. Lal, R. Gupta, D.P. Agrawal
The use of directional antennas in cellular wireless networks offers many advantages such as range extension, reduced interference for signal detection and improved throughput. MAC protocols using directional antennas for wireless ad hoc networks that are based on and similar to IEEE 802.11 type WLANs have been proposed. We explore 'multiplexing in space' with directional antennas to enhance the t... hiện toàn bộ

Very efficient wireless frequency usage by coherent addition of multipath signals using ZCCZ sequence set
Proceedings - International Symposium on Computers and Communications - - Trang 831-834
N. Suehiro, T. Imoto, N. Kuroyanagi
For future information technology, the efficiency of the wireless frequency usage is very important. In the current technology, the most serious problem for wireless communication is the multipath problem. We have proposed a very efficient frequency usage system based on multipath estimation and spread time signals based on the signal design of zero correlation zone (ZCZ) signals using complete co... hiện toàn bộ

Mobile agent solutions for accounting management in mobile computing
Proceedings - International Symposium on Computers and Communications - - Trang 753-760
P. Bellavista, A. Corradi, S. Vecchi
The convergence of mobile telecommunications and the Internet global system forces us to reconsider traditional client/server solutions for network and systems management. The paper claims that accounting in the mobility-enabled Internet requires support infrastructures hosted in the fixed network. These infrastructures should monitor, control and register resource consumption locally within the d... hiện toàn bộ
