Broadband and VPN

Vietnamese enterprises have many ADSL Internet service packages to choose from. They can also deploy internal security network systems running on Vietnam's public Internet infrastructure.

Broadband transmission line for businesses

Currently, ADSL Internet broadband Internet connection almost becomes an indispensable working tool for all organizations and enterprises. Although different in operating scale, ADSL is still the most effective and economical means for enterprises to exchange information with customers via email, update website content, search for information on the Internet, and even develop declare value-added services such as voice over Internet protocol (VoIP - Voice over Internet Protocol), video conferencing (Video Conference) or set up virtual private network (VPN - Virtual Private Network).

One of the first factors that enterprises need to consider when registering for ADSL service is the upload / download speed of each package (also called bandwidth). ADSL packages to serve customers who are now offered by FPT Telecom, SPT, VDC and Viettel support high download speeds, from 1Mbp / s to 4Mbps.

Most of these packages do not provide customers with static IP addresses, except MegaBiz (FPT), MegaVNN-Pro (VDC), Speed ​​3000/4000 (SPT). According to experts with experience in building and managing intranet at companies and agencies, in theory, the line of 2Mbps or more is fully capable of meeting the needs of web surfing and exchanging e. -mail of an office with about 30 employees. The higher the bandwidth, the faster the access speed and the number of users simultaneously increases (though not linearly).

However, according to many users, the actual ADSL speed of most providers is often lower, even much lower than the rate stated in the contract. Many transmission lines are still flickering, causing network failures. Meanwhile, customer support is often delayed, especially during holidays. This is a consequence of massive subscriber growth in the past. According to VDC's sales department, when the market has developed, suppliers will gradually shift from competing with freight to competitive services in the future, the trend of more quality competition.

For some companies using ADSL connection to build virtual private network (VPN), besides high bandwidth, the stability of the transmission line is the criterion to bring out 'metering scale' carefully before posting. sign. With this solution, most network administrators in enterprises decide to choose a service provider just because 'they believe in prestige (here is the stability of the transmission line) that suppliers have shown. with other enterprises or organizations', said Luc Tien Hung, IT Manager of Son Jotun Vietnam Co., Ltd. The advantage of VPN model via ADSL is much cheaper than the form of lease line or other virtual private network services (monthly subscription fee can be up to several tens of millions. VND), however, customers are not guaranteed bandwidth between the two locations that need to deploy the connection.

Particularly for SCTV cable television subscribers (in some specific areas of districts 1, 3, 4, 5, 10, 11, Tan Binh, Phu Nhuan and Binh Thanh), besides the choice of tape connection services ADSL width of 4 above suppliers, customers can register to use MediaNet high speed Internet access service (affiliated with EVN Telecom) provided right on the available cable. MediaNet currently offers 5 service packages, divided into 2 groups: The first group for families including Home Economic, Home Basic, Home Extra; the second group for families needs to use multiple computers or small businesses like Home Office and Home Public with bandwidths of 3Mbps and 4Mbps respectively. In the North, this service of EVN Telecom combined with VCTV is temporarily suspended to wait for the upgrade of the TV cable.

Virtual private network service

Virtual private network (VPN) is a communication network used by enterprises to communicate information with partners or internally securely on public networks. Currently, VPN is widely used globally. For example, company employees can connect from home to their computers in the office or a shared computer to run professional software or to retrieve data files to the home computer through the network. VPN is located inside the Internet.

Many businesses with a strong team of technicians can build VPNs themselves. However, small or non-IT companies, if they need to build virtual private networks with high bandwidth and high stability, can use virtual private network services such as MetroNet (Ho Chi Minh City Post Office). ) and V-Connect + (SPT).

MetroNet is a multi-service broadband urban network service, mainly using fiber optic lines, supporting speeds up to 1Gbps. With high bandwidth and ability to adjust to each bandwidth level, MetroNet is well suited for the need to connect, access, exchange information, deploy large applications for many different locations; as well as connecting to ADSL service of other ISPs. MetroNet allows customers to set up a network according to the point-to-point (P2P), point-to-multipoint (P2MP) model for the layer 2 and layer 3 network structures. VND 20,000,000 or VND 5,000,000 for copper cable transmission lines. Every month, customers have to pay port rental fee (VND 337,000 or VND 673,000) plus up-link fees depending on the required speed (minimum VND 1,661,000 / channel / month / 1Mbps, maximum 55,060 .000 VND).

V-Connect + operates on the IP network, applying Multi Protocol Label Switching (MPLS) technology to access and share data safely and effectively for organizations and businesses There are branches located in many different localities and countries by creating a separate line on the Internet. Currently, in addition to providing this service nationwide, SPT allows customers to use V-Connect + to create VPN deployment to countries such as Singapore, Hong Kong, England, Germany, USA, Australia, New Zealand, Japan Edition, Korea, China, Taiwan, Thailand, Philippines and Malaysia. As expected, the network connection price of V-Connect service is VND 4,800,000 (channel 64-896Kbps) or VND 5,600,000 (channel 1,024-2,048Kbps), monthly package subscription fee fluctuates within 13,700,600 - 96,572,600 VND.
