nfdc-strategy

SYNOPSIS

nfdc strategy [list]

nfdc set-strategy <prefix> <strategy>

nfdc unset-strategy <prefix>

DESCRIPTION

In NFD, packet forwarding behavior is determined by forwarding pipelines and forwarding strategies. The forwarding pipelines define general steps of packet processing. Forwarding strategies provide the intelligence to make decision on whether, when, and where to forward Interests.

NFD contains multiple forwarding strategy implementations. The strategy choice table determines which strategy is used in forwarding an Interest.

The nfdc strategy list command shows the strategy choices.

The nfdc set-strategy command sets the strategy for a name prefix.

The nfdc unset-strategy command clears the strategy choice at a name prefix, so that a strategy choice at a shorter prefix or the default strategy will be used. It undoes a prior nfdc set-strategy command on the same name prefix.

OPTIONS

<prefix>

The name prefix of a strategy choice. The strategy choice is effective for all Interests under the name prefix, unless overridden by another strategy choice. Specifying ndn:/ as the prefix in nfdc set-strategy changes the default strategy. Specifying ndn:/ as the prefix in nfdc unset-strategy is disallowed, because NFD must always have a default strategy.

<strategy>

A name that identifies the forwarding strategy. Consult NFD Developer’s Guide for a complete list of all implemented strategies.
