The first MAN network in Vietnam officially operates

Ho Chi Minh City Post Office has cooperated with DTS Communication Technology Joint Stock Company to deploy and introduce the first broadband urban network (MAN) in Vietnam in Ho Chi Minh City with many utilities and types. new service .

The MAN network is the result of the ' Broadband Urban Network ' project jointly implemented by HCMC Post and DTS Company. This project is done in a turn-key manner, based on a combination of RPR / DPT transmission technology (Resilient Packet Ring / Dynamic Packet Transport) and the leading concern of MPLS label switching technology. now on. This is a modern network following the model of Next Generation Metro Network.

The network is capable of delivering very large bandwidth and enables the provision of high-speed Ethernet interfaces up to Gigabit to every office, business, building, high-end residential area, where the need for interconnection exchanging internal information between the head office and other branches and facilities on a large and separate geographical area of ​​interest.

Vietnam's first ' Broadband Urban Network ' project was completed on April 25, 2005 on the occasion of the 30th anniversary of the Liberation of the City and the reunification of the country in Ho Chi Minh City.DTS Communication Technology Joint Stock Company has been selected as the selected unit to directly supply and install the equipment system for the Project, build broadband network infrastructure connecting Government offices, step head for the deployment of e-Government in HCM City.

The highlight of the project is the application of RPR / DPT technology on intelligent MPLS Routing Systems. RPR technology allows the system to deploy on city fiber optic circuits that provide protection to redundancy when a fault occurs on the main connection line. transit time is very fast - 50 ms, time is very difficult to achieve on normal routing systems.

The solution is the combination of high availability of RPR technology with the intelligent routing features of Cisco Routing System such as quality of service (QoS) and the latest features of MPLS technology. like ATOM (Any Transport over MPLS). These high-end features meet the strict criteria of bandwidth, speed, and quality that enable the deployment of high-end services such as Voice, Television, and conference communications services of the Urban generation network. new.

The devices used in the core network use Cisco nx10Gbps technology routers with very high switching, availability and stability capabilities. Currently the core network uses STM-16 RTR / DTP speed interfaces but RPR technology allows optimization of packet transmission on the network, so the total throughput on the network is up to 5 Gbps instead of only 2.5 Gbps as using technology Traditional SDH transmission today.

Typical MAN network model

With a network solution based on Cisco's famous Urban Ethernet Solution, Ho Chi Minh City Post Office can provide similar services as traditional services such as Private Channel-Leased line service (provider The service uses the network bandwidth resources in the most efficient way, providing private leased channels with multiple interfaces, multiple speeds and can provide leased lines with very high speeds up to hundreds of Mbit / s) , frame relay (Frame Relay) . but the speed is much greater, the time to meet service requirements quickly.

In addition, new services such as providing virtual LANs for urban users with flexible point-to-point and point-to-point connectivity models. These connections can change the bandwidth on demand and service efficiently and quickly from Megabit to Gigabit.

With these advantages, the urban network constitutes a converged network architecture that integrates many of the most advanced IP-based applications and services such as broadband Internet access, network data centers, and private networks. Virtual IP VPN, VoIP, Video on demand, video conference with outstanding advantages of voice, image, data, content distribution on the same network with superior service quality at a cost much lower in investment as well as operating and operating systems compared to previous traditional urban networking technologies.

Broadband Network This city can easily connect to other service networks such as DSL, new generation voice, Internet . available from Ho Chi Minh City Post Office as well as VNPT.
