Discover local hub prefixΒΆ
Some applications need to discover prefix(es) under which they can publish data
/ which Interests local hub will be able to forward down to the application.
In order to discover that, applications need to send an interest for
/localhop/nfd/rib/routable-prefixes
prefix. Response data to the
interest contains a list of prefixes and should be encoded as:
Response ::= DATA-TYPE TLV-LENGTH
Name (= /localhop/nfd/rib/routable-prefixes/[version]/[segment])
MetaInfo (= ResponseMetaInfo)
Content (= ResponseContent)
Signature
ResponseMetaInfo ::= META-INFO-TYPE TLV-LENGTH
ContentType (= DATA)
FreshnessPeriod (= 5000)
ResponseContent ::= Name+
Note
ResponseContent should contain at least one Name, which should be routable towards the face from which the request has been received. The requester may process list of the returned names and pick whichever it wants to use.
For now, the /localhop/nfd/rib/routable-prefixes
data is served by
ndn-autoconfig-server.
