Network redimensioning (medium term planning) means to determine volume of telecommunication resources, necessary to serve given traffic offered taking into account the prescribe Quality of services (QoS). Two different network redimensioning methods are considered in this paper. The aim of the research is comparison between network redimensioning method, using ITU E.600 traffic offered definit...

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract This document specifies Operations and Management (OAM) requirements for Multi-Protocol Label Switching (MPLS), as well as for applications of MPLS, such as pseudo-wire voice and virtual private network services.

This paper presents a new NoC QoS metrics modeling shaped on mesh architecture. The new QoS model is based on the QoS parameters. The goal of this work is to quantify buffering requirements and packet switching techniques in the NoC nodes by analyzing some QoS metrics such as End-to-End delays (EEDs) and packet loss. This study is based on simulation approach of a 4 × 4 mesh NoC behavior under ...

Voice over IP (VoIP) is a technology to transport media over IP networks such as the Internet. VoIP has the capability of connecting people over packet switched networks instead of traditional circuit switched networks. Recently, the InterAsterisk Exchange Protocol (IAX) has emerged as a new VoIP which is gaining popularity among VoIP products. IAX is known for its simplicity, NAT-friendliness,...

Users need high speed and low latency transmission for new applications. Since Ethernet is the dominant LAN technology, service providers wish to offer new Ethernet services as Layer 2 Virtual Private Network (L2VPN), to meet the requirements of these applications. MultiProtocol Label Switching (MPLS) is one of the most suitable technologies to deploy L3VPN and can also be used to realize L2VPN...

This paper analyses and compares the performance of forward planning conflict-free (FPCF), virtual output queuing-partitioned (VOQ-P) and virtual output queuing-shared (VOQ-S) packet switches. The influence of packet burst size, offered switch load and packet switch size are all investigated. Packet loss probability, average packet delay and 99.9% packet delay values are also derived. In compar...

Discrete-time communication networks are studied as due to digital transmissions. Simultaneous multiple transmission requests and completions as well as blocking are hereby involved. Scheduling times and packet lengths are allowed to have a general discrete distribution. A discrete-time product form result is obtained for the steady-state busy source distribution. Particularly, this form is sho...

Thank you very much for inviting me to speak with you today. Recently, the Federal Communications Commission (FCC) has been spending a great deal of time and energy considering the best, most appropriate regulation of broadband networks and IP-enabled services.1 Today, I want to focus on an important aspect of our discussions. Namely, what are the implications of the digital revolution for our ...

A hybrid channel assignment (HCA) scheme in direct sequence-code division multiple access (DS-CDMA) systems for accommodating integrated voice/data traffic is proposed and the required power levels of voice and data traffic are derived. These levels can be used to maintain the minimum required link qualities of all calls. In the proposed scheme, delay-sensitive voice traffic is accommodated in ...
