• B

    The bandwidth represents network usage, facilitating service charging.

  • E
    elastic IP address

    The elastic IP address service provides legal static IP addresses to be used on the Internet. After ECSs on a routed network in a VPC are bound with elastic IP addresses, services in the VPC are accessible to the Internet.


  • I
    IPsec VPN

    IPsec VPN is an encrypted tunneling technology that uses encrypted security services to establish confidential and secure communication tunnels between different networks.


  • R
    remote gateway

    A remote gateway is the public IP address of the physical device on the peer end in an IPsec VPN tunnel. The remote gateway of each IPsec VPN tunnel must be unique.

    remote subnet

    A remote subnet is the destination IP addresses reachable through the tunnel. All IP packets destined for this subnet are sent along the IPsec VPN tunnel. Multiple remote subnets can be configured. However, the remote subnet cannot conflict with the subnet of the VPC where the VPN resides.

  • S
    security group

    A security group implements access control for ECSs, enhancing ECS security. You can define different access control rules for a security group, and these rules take effect for all ECSs added to this security group.


    A subnet is a network that manages ECS network planes. It supports IP address management, DHCP, and DNS services. The IP addresses of all ECSs in a subnet belong to this subnet.


  • U-Z
    Virtual Private Cloud

    Huawei Virtual Private Cloud (VPC) enables you to provision logically isolated virtual networks. You can select your own IP addresses and divide network segments for these virtual networks. The virtual networks provide the same network functions as those provided by a physical network and also advanced network services, such as elastic IP addresses and security groups.

    virtual private network

    The virtual private network (VPN) service establishes an encrypted communication tunnel between a remote user and a VPC, thereby enabling the remote user to use service resources in the VPC.
