We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
Three applications in wireless networks where model-free stochastic learning is applicable, are discussed. The learning based optimization problems are formulated and simulation results are presented. Some open issues are also discussed.
Equivalent bandwidth (EqB) is defined as the minimum service rate to be provided to a traffic buffer to guarantee a certain degree of quality of service (QoS) in terms of objective parameters (packet loss, delay, jitter). EqB techniques are usually obtained analytically for homogeneous traffic trunks, with respect to a single QoS constraint. Modern network solutions often imply the aggregation of...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
