cwnd-max Parameter

Description

Defines the maximum value of the TCP congestion window in bytes.

For more information about the TCP congestion window, refer to RFC 1122 and RFC 2581.

Default

1,048,576

Range

128 to 1,073,741,824

Dynamic?

Yes

When to Change

This parameter does not need to be changed in normal circumstances. If the system needs to communicate with peers far away (round trip time in the order of hundreds of milliseconds) using very fast network (in the order of Gbps), increase the default value to match the bandwidth-delay product to those peers. Note that max-buf Parameter should also be increased at the same time.

Commitment Level

Stable
