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 2 (switching) level rather than at the layer 3 (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 Supervisor: Nguyễn Đức Quang QoS over MPLS for Hutech network Student: Trần Quang Hải Đăng - 7 - 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 for setup and link to MPLS/VNN Order Speed Price for channel TDNH (VND/channel/time) Price for setup, link to network VPN/VNN(VND/ch annel/time) 1 64 Kbps 1,500,000 2,000,000 2 128Kbps<speed <=896kbps 5,000,000 2,000,000 3 1Mbps<speed<= 2Mbps 5,000,000 3,000,000 4 2Mbps<speed<= 10Mbps 20,000,000 5,000,000 5 10Mbps<speed<=155Mbps 20,000,000 10,000,000 Price for month: (Upcountry price + Service price MPLS/VNN) Order Speed Price for channel TDNH (VND/port /month) Price for all (VND/port /month) 1 64Kbps 609,000 958,000 2 128Kbps 875,000 1,447,000 3 192Kbps 1,104,000 1,694,000 4 156Kbps 1,370,000 1,941,000 5 384Kbps 1,705,000 2,415,000 6 512Kbps 2,114,000 2,994,000 7 768Kbps 2,600,000 3,558,000 8 896Kbps 2,886,000 3,682,000 9 1024Kbps 3,171,000 3,928,000 10 1536Kbps 4,394,000 5,442,000 11 2048Kbps 5,112,000 5,978,000 12 4Mbps 10,224,000 11,561,000 Supervisor: Nguyễn Đức Quang QoS over MPLS for Hutech network Student: Trần Quang Hải Đăng - 8 - 13 6Mbps 15,758,000 14 8Mbps 18,914,400 20,529,000 15 10Mbps 25,661,000 16 34Mbps 24,536,000 33,034,000 17 45Mbps 42,173,000 63,964,000 Advantage of MPLS: -Security (absolute security in core MPLS network and local loop network). -Flexible (Easy for wire-open). -Easy for administrator control.
