This document describes the outbound and inbound bandwidth caps of CVM instances, and compares the peak bandwidth in different billing modes.

Outbound Bandwidth Cap (Downstream Bandwidth)

The public network bandwidth cap refers to the upper limit of outbound bandwidth, that is, the bandwidth going out from CVM instances. The public bandwidth cap varies by network billing mode.
The following rules apply to instances created after 00:00, February 24, 2020 (UTC +8):

Inbound Bandwidth Cap (Upstream Bandwidth)

The public network inbound bandwidth refers to the bandwidth that flows into CVM instances.
Bill-by-traffic public IP:
If the bandwidth you purchased is less than or equals to 10 Mbps, Tencent Cloud will assign 10 Mbps public network inbound bandwidth.
If the bandwidth you purchased is greater than 10 Mbps, Tencent Cloud will assign a public network inbound bandwidth equals to the purchased bandwidth.
Bill-by-BWP public IP: Tencent Cloud will assign a public network inbound bandwidth equals to the purchased bandwidth.

Peak Bandwidth

The peak bandwidth is applicable to both bill-by-traffic and bill-by-bandwidth, but it means differently in these two cases as follows:
Billing Mode
Difference
Description
Bill-by-traffic
The peak bandwidth is only regarded as the maximum peak bandwidth, and not as the committed bandwidth. When bandwidth resources are contested, the peak bandwidth may be limited.
The sum of peak bandwidth of all the running bill-by-traffic instances (such as CVMs, EIPs, and elastic IPv6 addresses) cannot exceed 5 Gbps in one region. If your application requires a guaranteed or higher bandwidth, choose bill-by-bandwidth.
Bill-by-bandwidth (monthly bandwidth subscription)
This peak bandwidth is the committed bandwidth, and is guaranteed in case of bandwidth competition.
The sum of peak bandwidth of all the running instances such as CVMs and EIPs that are billed at a fixed bandwidth (monthly bandwidth subscription) cannot exceed 50 Gbps in one region. If you require a higher bandwidth, contact your sales rep.
