Transmission

Realisation of projects with consistency, stringency, purposivity, quality.

IEPL

A fully transparent point-to-point and point-to-multipoint private line service with strict bandwidth guarantee and dedicated customer bandwidth.

International Ethernet private line provides customers with flexible bandwidth adjustment (2Mbps to 10Gbps) and Ethernet access capacity based on the multi-service transmission platform technology (MSTP) and relying on the SDN/MSTP/OTN transmission network of China Unicom. It is a fully transparent point-to-point and point-to-multipoint private line service with strict bandwidth guarantee and dedicated customer bandwidth.

Global coverage

Business covering all cities in mainland china as well as 50 major overseas countries and regions, with rich submarine and land cables and satellite transmission resources around the world

High network reliability

Providing highly protected services to ensure that the customers' businesses are properly secured.

High security

Providing end-to-end management. Physical isolation between customers, and exclusive bandwidth with high security is provided.

Excellent network performance

Providing fixed latency and very low jitter value.

IPLC

Providing cross-border and cross-region customers real-time transmission application designated for level-1 international data with the globally-covered SDH/WDM transmission network.

Providing cross-border and cross-region customers with bandwidth real-time transmission application designated for level-1 international data with the globally-covered SDH/WDM transmission network, which is a fully transparent end-to-end private line service with strict bandwidth guarantee and dedicated customer bandwidth.

Global coverage

Rich land, submarine cables and satellite transmission resources, covering all cities in mainland china as well as 50 major overseas countries and regions.

Highly secure

Providing end-to-end management. Physical isolation between customers, and exclusive bandwidth with high security is provided.

Easy access

Standard ethernet interface, without the need to invest in new equipment, and with easy network upgrade and short delivery time.

Ethernet intelligent monitoring

Deploying intelligent monitoring platform for customers to check line status realtime.

VLL

Supporting the transparent transmission of customer data on Layer 2 or above protocols, satisfying their needs to transmit network services such as voices, videos, images and data.

Virtual Leased Line is a Layer-2 Ethernet VPN service that adopts VLL technology to provide point-to-point and point-to-multipoint Ethernet virtual private line service on the IP/MPLS network for the customers' branch institutions located in different countries and regions. It supports the transparent transmission of customer data on Layer 2 or above protocols to satisfy their needs to securely and transparently transmit network services such as voices, videos, images and data.

High availability

VLL is carried on the A network of Unicom, with high redundancy of network device plate. It adopts master/slave and load modes for interconnection, with multiple interconnections and multiple uplinks. It is highly available and extremely reliable;

High Security and Privacy

VLL service is located on the carrier network of Unicom's A network, which is separated from the Internet. Each VLL also independently establishes the VC point-to-point interconnection, so VLL customers cannot obtain data from each other

Rapid data transmission

VLL realizes the two-layer data transmission of customers on different nodes. Interconnection can be realized through the direct MAC search between nodes, which is faster and simpler than the one-by-one IP address resolution at Layer 3
