Strategy Choice Management¶

Strategy Choice Management is a module of NFD Management protocol.
It provides:

• commands to choose the forwarding strategy for a namespace
• a dataset of strategy choices

Strategy Choice Management commands and datasets are published in namespace ndn:/localhost/nfd/strategy-choice.

Strategy¶

A strategy is represented by a Name.

NFD currently supports builtin strategies only. The following strategies are available:

• ndn:/localhost/nfd/strategy/best-route
• ndn:/localhost/nfd/strategy/broadcast
• ndn:/localhost/nfd/strategy/client-control
• ndn:/localhost/nfd/strategy/ncc

Control Commands¶

ControlCommand management-module: strategy-choice

Set the strategy for a namespace¶

command-verb: set

ControlParameters fields:

• Name (required)
• Strategy (required)

Strategy must be a Name that represents a builtin strategy.

If Strategy does not match any builtin strategy, the command fails with code 504.

Unset the strategy for a namespace¶

command-verb: unset

ControlParameters fields:

• Name (required)

After this operation, the effective strategy at Name is inherited from the parent.

If there is no strategy defined at Name, this command does nothing, but is still considered successful.

Name must not be ndn:/, otherwise the command fails with code 403.

Strategy Choice Dataset¶

Strategy choices for namespaces are published as a Status Dataset at ndn:/localhost/nfd/strategy-choice/list.

Each face is represented by a StrategyChoice block:

StrategyChoice := STRATEGY-CHOICE-TYPE TLV-LENGTH
                    Name
                    Strategy

• Name is the namespace on which a strategy is chosen.
• Strategy is the strategy chosen for this namespace.

TLV-TYPE assignments¶
