Assigning a Shared Bandwidth

Scenarios

When you host a large number of applications on the cloud, if each EIP uses a dedicated bandwidth, a lot of bandwidths are required, which incurs high costs. If all EIPs share the same bandwidth, your network operation costs will be lowered and your system O&M as well as resource statistics will be simplified.

Assign a shared bandwidth for use with EIPs.

Procedure

  1. Go to the Buy Shared Bandwidth page.
  2. Set the parameters as prompted.

    Parameter

    Description

    Example Value

    Basic Configuration

    Region

    Regions are geographic areas that are physically isolated from each other. The networks inside different regions are not connected to each other, so resources cannot be shared across different regions. For lower network latency and faster access to your resources, select the region nearest to you.

    CN-Hong Kong

    Basic Configuration

    Billing Mode

    A shared bandwidth can be billed on a yearly/monthly or pay-per-use basis.

    • Yearly/Monthly: You pay for the bandwidth by year or month before using it. No other charges apply during the validity period of the bandwidth.
    • Pay-per-use: You pay for the bandwidth based on the amount of time you use the bandwidth.

    Yearly/Monthly

    Basic Configuration

    Name

    The name of the shared bandwidth.

    Bandwidth-001

    Basic Configuration

    Enterprise Project

    The enterprise project that the EIP belongs to.

    An enterprise project facilitates project-level management and grouping of cloud resources and users. The name of the default project is default.

    Bandwidth Type

    Select a type of the shared bandwidth based on your EIP type.

    • Standard: Dynamic BGP and static BGP EIPs can be added to a shared bandwidth of this type.
    • Premium BGP: Premium BGP EIPs can be added to a shared bandwidth of this type.
    NOTE:

    In the CN-Hong Kong region, only dynamic BGP EIPs can be added to standard shared bandwidths.

    Bandwidth Details

    Billed By

    The billing method for the shared bandwidth.

    You can specify a shared bandwidth to be billed by bandwidth, 95th percentile bandwidth (enhanced).

    NOTE:
    • 95th percentile bandwidth (enhanced) can be selected only when Billing Mode is set to Pay-per-use.
    • Only customers with a level of V4 or higher can use the enhanced 95th percentile bandwidth billing. Enhanced 95th percentile bandwidth billing is based on average monthly bandwidth usage excluding peak traffic values. The charges will be deducted from your account balance on a monthly basis. You can specify the guaranteed minimum bandwidth by setting the bandwidth size and the minimum bandwidth percentage. If the monthly peak bandwidth is less than or equal to the guaranteed minimum bandwidth, you will be billed based on the guaranteed minimum bandwidth. If the monthly peak bandwidth is greater than the guaranteed minimum bandwidth, you will be billed based on the monthly peak bandwidth.
    • If the enhanced 95th percentile bandwidth billing is used, the minimum shared bandwidth is 300 Mbit/s.

    For more information, see 95th Percentile Bandwidth Billing (Enhanced).

    Bandwidth Details

    Bandwidth (Mbit/s)

    The bandwidth size in Mbit/s. The minimum value is 5 Mbit/s.

    QoS

    After QoS is enabled, you can configure the bandwidth limits for each EIP that uses the shared bandwidth. This makes sure each EIP gets enough bandwidth and uses it better. Configuring bandwidth limits for EIPs is free of charge. For details, see QoS.

    Required Duration

    Required Duration

    The duration for which the purchased EIP will use. The duration must be specified if the Billing Mode is set to Yearly/Monthly.

    2 months

    Required Duration

    Auto-renew

    Whether to select Auto-renew. You can select it if the Billing Mode is set to Yearly/Monthly. The auto-renewal period is determined by the required duration.

    • Monthly subscription: The subscription is renewed every month.
    • Yearly subscription: The subscription is renewed each year.
