ONE VPN Enterprise

Diagram | Comparison

ONE VPN Enterprise is a regionwide state-of-the-art service that delivers the security and performance levels of a private IP network from a shared public infrastructure. More specifically, it provides connectivity between sites across Diyixian’s backbone in a secure manner with the same policies as a private network.

In the modern business environment, companies are increasingly under pressure to support a wide variety of voice and data communication channels between cities or locations. Employees also need to access and share information as they travel or work from remote locations or branch offices around the world. Existing WAN technologies, such as International Private Leased Circuit (IPLC) or a pure Internet access, are either too expensive or limited in their flexibility to meet changing business requirements (for example, a leased line connecting two small offices is expensive to maintain). It is out of such inadequacy that IP VPN technology has emerged as the solution.

What differentiates ONE VPN Enterprise from its competitors?

Diyixian is one of the first IP VPN service providers in the region to deliver superior Quality of Service (QoS) with the Multiprotocol Label Switching (MPLS) technology. MPLS is a key routing protocol for service providers to steer IP traffic onto a variety of routes instead of one single channel, to avoid congestion or failures, or to achieve what effective QoS aims to achieve - minimized traffic delay, optimized data throughput, and minimized jitter and loss of data packets. MPLS enables enterprises and service providers to supercharge their VPNs, dramatically improving scalability, performance and security.

Since IP is fast becoming the dominant networking protocol in the world, our MPLS-based IP VPN service has become one of the region's most practical, future-proof ways of delivering the full chain of time-sensitive applications over corporate IP networks. Examples of these emerging applications include, VoIP, video streaming, video conferencing, IP fax, and other e-business solutions.

Differences between ONE VPN Enterprise, IPLC and pure Internet access

The most competing products for MPLS IP VPN is IPLC which is a more traditional point-to-point connection and suffers from a number of disadvantages. IPLC requires the self-provision by businesses of their own communication needs over their own networks. Businesses build their own internal corporate networks by purchasing IPLCs and leased lines, and then adding on top of these lines the necessary equipment (e.g. switches, routers, etc.). Such a solution involves in-house management and maintenance of the corporate network, which could prove a very complex task, requiring numerous and skilled staff.

Pure Internet access involves sole reliance on non-customized basic telecommunication services purchased locally from various suppliers. However, the Internet is not a controllable and predictable environment. Consequently, as soon as data packets get into the Internet, rather than a single controlled IP network, they are subject to unpredictable quality issues like packet drops, delays and jitters.
