- allows specifying segment range.
- supports segment numbers.
- supports byte offsets.
- supports multiple naming conventions.
- has Interest pipelining, congestion control, and loss recovery.
- verifies packets with a
Verifier
(fixed key or trust schema). - emits events as segments arrive.
- outputs in-order data chunks as a readable stream.
- outputs completely reassembled object via Promise.
The producer functionality:
- takes input from
Uint8Array
. - takes input from readable streams.
- takes input from files (filename in Node.js,
Blob
in browser). - generates segments of fixed size.
- generates segments of available data as Interest arrives, to minimize delivery latency.
- responds to version discovery Interests with CanBePrefix.
- responds to RDR protocol (in
@ndn/rdr
package). - generates manifest.
- supports segment numbers.
- supports byte offsets.
