Introduction about network system of Hutech University, problem of Hutech network system, solution to resolve Chapter 2: Chapter includes three parts Part 1: Overview about MPLS, architecture MPLS packet, operation of MPLS network, command line for configure MPLS operation Part 2: Overview about QoS, architecture of QoS, classification, marking and queuing tool Part 3: QoS over MPLS, relative about IPP, DSCP and MPLS EXP, DiffServ with IP packet and MPLS packet, DiffServ tunneling mode, steps implement QoS over MPLS network Chapter 3: Network design and implement Deploy QoS over MPLS, get

Distribution Protocol Student: Trần Quang Hải Đăng -5- Supervisor: Nguyễn Đức Quang QoS over MPLS for Hutech network Multiprotocol Label Switching Multiprotocol Label Switching (MPLS) is a standards-approved technology for speeding up network traffic flow and making it easier to manage MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to MPLS is called multiprotocol because it works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay network protocols With reference to the standard model for a network (the Open Systems Interconnection, or OSI model), MPLS allows most packets to be forwarded at the layer (switching) level rather than at the layer (routing) level In addition to moving traffic faster overall, MPLS makes it easy to manage a network for quality of service (QoS) For these reasons, the technique is expected to be readily adopted as networks begin to carry more and different mixtures of traffic Actuality of MPLS at VietNam -With VietNam, MPLS deployment are building in communication network at VNPT head of company VietNam With VoIP project is deploying, VNPT established an axle MPLS network with three LSR core LSRs edge will be invested and extended at places have large demand as Hai Phong, Quang Ninh at north, Da Nang, Khanh Hoa…at medium, Binh Duong, Dong Nai, Ba Ria – Vung Tau…at south Next, FPT Telecom, Viettel, electricity are taked part and create competition environment with high QoS and cheap - Present, not including companies and foreign office representative, there are a lot of home companies in finance field, insurance, bank use this service (Bao Viet insurance company, Dong A bank…) Beside that, arrange state as Ministry of Finance, customs, treasury, tax associated together by VPN/MPLS -VPN/MPLS technology officially deployed, applied and test successfully and inserted to exploited from 2003 by VDC 2004, VPN MPLS solution of VDC Student: Trần Quang Hải Đăng -6- Supervisor: Nguyễn Đức Quang QoS over MPLS for Hutech network saved up technology information IT Week 14 gold cup and extended to exploited on all 64 provinces of all the country with trade name VPN/VNN - VPN/VNN MPLS solution of VDC apply and deploy to rely on pass and device technology of Cisco, with target create a network solution safe, security, slow late and intergrate with each apply as Data, Voice, Video… Price for first setup: include price
