What Are the Differences Between the Bandwidth of a VPN Connection and That of a Direct Connect Connection?

Concepts

  • The bandwidth of a Direct Connect connection is the bandwidth of the physical connection created by a user.
  • The bandwidth of a VPN connection applies to the outbound direction of the cloud.

Maximum Bandwidth

  • By default, the maximum bandwidth of a Direct Connect connection is 1000 Mbit/s. When you create a connection on the management console and set Port Type to 10GE single-mode optical port, the maximum bandwidth is 10 Gbit/s.
  • The maximum bandwidth supported by a VPN gateway is as follows:
    • The maximum bandwidth supported by a VPN gateway of the Basic specification is 100 Mbit/s.
    • The maximum bandwidth supported by a VPN gateway of the Profession 1 specification is 300 Mbit/s.
    • The maximum bandwidth supported by a VPN gateway of the Profession 2 specification is 1 Gbit/s.
    • The maximum bandwidth supported by a VPN gateway of the Profession 3 specification is 5 Gbit/s.
    • The maximum bandwidth supported by a VPN gateway of the GM specification is 500 Mbit/s.

Network Quality

  • A Direct Connect user has a dedicated connection with high network quality.
  • VPN connections share the bandwidth of their VPN gateway. That is, the total bandwidth of VPN connections cannot exceed the bandwidth of the corresponding VPN gateway. The network quality will be affected by the Internet quality.
