MPLS-VPN
MPLS-VPN refers to the use of MPLS technology in the carrier's broadband IP network to build enterprise IP private network, to achieve cross-regional, secure, high-speed, reliable data, voice, image multi-service communications, and combined with differential services, traffic engineering and other related technologies, the reliable performance of the public network, good scalability, rich functionality, and the security of the private network, flexibility, efficiency, and to provide high quality services for users. Provide high quality services for users.
Each interconnection node of CHCI has interconnection with the operator, such as the enterprises have higher delay requirements for interconnection.
MPLS-VPN is a better choice to reduce interconnection costs across provinces or cities by combining the carrier's local interconnections with HHI's node interconnections.
GRE-VPN
GRE VPN uses tunneling technology to create a tunnel across the public network by connecting the routers of two sites through the public network to encapsulate and unencapsulate data messages.
GRE (Generic Route Encapsulation) is a three-layer tunnel encapsulation technology that allows the encapsulation of messages for certain network layer protocols, solving the problem of transmitting messages across heterogeneous networks.
The core equipment deployed in each interconnection node of China International is Cisco's network equipment, and GRE is Cisco's proprietary network protocol, so corporate offices can easily use China's existing GRE resources for interconnection services.
SD-WAN Networking
Software-Defined WAN (SD-WAN) is a virtual WAN architecture that enables traffic decisions to be made from a centralized console, allowing bandwidth resources to be readily allocated to where the service is most needed, regardless of the connectivity of your infrastructure, including MPLS, LTE, and the Internet, among others.
China Internation uses carrier-grade SDWAN equipment in conjunction with its own backbone network to provide flexible and resilient network interconnection services for enterprises.
IPSEC VPN
IPSec is Internet Protocol Security, a framework of security standards defined by the Internet Engineering Task Force (IETF), which provides a secure communication channel between two private networks on a public network, and guarantees the security of the connection through an encrypted channel - - Provides private data packet services between two public gateways. -Provide private data packet service between two public gateways.
IPSec is a mainstream VPN with mature technology, security, flexibility and scalability.
