Fifth Generation New Radio (5G NR) presents a new framework for Quality-of-Service (QoS) management that especially fits cases eXtended Reality (XR) traffic applications thanks to the presented concept of QoS flows can handle various service data flows. In respect, in this paper we exploit flow model and present MAC scheduler classify XR mixed based on assigned indicators each traffic. We perfo...

Is it possible for a distributed filesystem to perform at the same speed as local disk filesystems, at least in important cases? This paper is trying to answer this question for traditional client-server distributed filesystems, not for distributed filesystems exploiting very fast networks and disk striping techniques. We claim the answer is ”yes”. Systems such as AFS, Sprite, Coda, Arla and DF...

Given the emergence of IP networks and the Internet as the multiservice network of the future, it is plausible to consider its use for transporting demanding traffic with high bandwidth and low delay and packet loss requirements. Emerging technologies for scalable quality of service such as Differentiated Services and MPLS can be used for premium quality traffic. We are looking at the problem o...

A number of air traffic management decision support tools (DST) are being developed to help air traffic managers and controllers improve capacity, efficiency, and safety in the National Airspace System. Although DST functionality may vary widely, trajectory prediction algorithms can be found at the core of most DST. A methodology is presented for the automated statistical analysis of trajectory...

We explore how to verify useful properties about networks that include “dynamic” elements, whose state and functionality may depend on previously observed traffic, e.g., caches, WAN optimizers, firewalls, and DPI boxes. We present the design and implementation of a tool that takes as input a network specification and verifies properties such as “traffic from host A will never reach host B direc...

2 ABSTRACT This paper describes the initial testing and evaluation of one of the key components of the Testbed Real-time Integrated Control and Evaluation Prototype System (TRICEPS). TRICEPS is a software platform that facilitates the implementation and evaluation of a wide range of algorithms for traffic control and Advanced Transportation Management Systems (ATMS). TRICEPS supports research a...

Traffic Engineering (TE) deals with the performance optimization in operational networks, aiming for example at the fair distribution of traffic in order to avoid or minimize congestion. Multi Protocol Label Switching (MPLS) is a key technology that enables advanced TE functionality. The MPLS framework consists of several components, such as the label switched forwarding plane, the label distri...

Evaluation of Intelligent Transportation Systems (ITS) at the planning level, as well as various short-term planning projects, require the use of appropriate tools that can capture the dynamic and stochastic interactions between demand and supply. The objective of this thesis is to develop a methodological framework for such applications and implement it in the context of an existing dynamic tr...

Earliest Deadline First scheduling with per-node traffic shaping (RC-EDF) has the largest schedulable region among all practical policies known today and has been considered a good solution for providing end-to-end packet delay bounds. In order to harness the traffic burstiness inside a network to satisfy the schedulability condition of EDF, pernode traffic shaping has been believed to be neces...

The push-to-talk technology provides a walkie-talkie like service for group communication. In this paper, we propose an efficient outbound voice traffic reduction scheme in the push-to-talk environment when network congestion happens. The Open Mobile Alliancepush-to-talk over cellular (OMA PoC) architecture, the standard for this kind of group communication, is used as a base network in this pa...
