Task #1205: NDNLP
NDNLP fragmentation and reassembly on Ethernet multicast face
Added by Junxiao Shi almost 11 years ago.
Updated almost 10 years ago.
Description
Add fragmentation in Ethernet sending path.
Each EthernetFace needs a single ndnlp::Slicer.
Add reassembly in Ethernet receiving path.
EthernetFace must distinguish the sender address, and create one ndnlp::PartialMessageStore per sender.
If a sender has been idle for some configuration duration, destroy its PartialMessageStore.
Modify link layer byte counters to reflect NDNLP byte counts.
In the receiving path, the byte counter should include all received NDNLP packets, even if a network layer packet could not be reassembled due to a lost fragment.
- Subject changed from NDNLP service on datagram channel to NDNLP fragmentation and reassembly on Ethernet multicast face

20140514 call decides it's not urgent because nobody is blocked on this feature.
- Blocks Task #1780: Link layer byte count in EthernetFace added

- Target version set to v0.3
20140910 conference call decides to include this feature in v0.3
Sounds good to me. Either Matteo or I will start working on this task as soon as possible.
- Assignee changed from Davide Pesavento to Matteo Sammarco
- Status changed from New to In Progress
What's the relationship between ndnlp::Slicer and the face? Should we create a new instance of Slicer for each packet that has to be fragmented, or should there be just one instance, member of EthernetFace, with the same lifetime as the face object?
Each EthernetFace needs a single ndnlp::Slicer.

Technically this feature conflicts with #2222, but I'll wait for this to merge before start implementation of #2222.
Hello Junxiao,
I didn't get you last update since on gerrit you wrote "It needs to go into ndn-cxx. This Change is blocked until then."
Thanks.

Please commit std::hash<ndn::Ethernet::Address> specialization code into ndn-cxx repository.
