[ndnSIM] [EXT] Naming in NDN

[Arif Hussain Magsi]

Dear Junxiao Shi,

Thank You for your guidance.

Is it possible if consumer sends a prefixed name i.e., NDN/vanet/incidents/

In the response, producer matches prefixed interest packet and send all the packets in single data packet?


Regards

Arif

Hi Arif

False and false.
NDN Protocol Design Principles
https://named-data.net/project/ndn-design-principles/ allow only one Data packet in reply to each Interest. It isn't possible for a producer to send multiple Data packets to one Interest.

You need a dataset synchronization protocol, such as PSync PartialSync, for this use case.

Yours, Junxiao

Dear Members,

Can you please guide me following please?

1. In NDN, a newly joining consumer wants to receive all the data packets which were shared previously. To do so, a consumer broadcast prefix interest such as:
 NDN/vanet/incidents/

In the response, a producer provides data packet in following naming structure

Ndn/vanet/incidents/sequence_No/event

Is above hypothesis correct?

2. In NDN, a consumer remains absent for certain time, during his absence many packets were shared. After rejoining, a consumer wants to receive all those packets which were shared during his absence. To solve this problem, a consumer can send a signed interest that includes consumer's timestamp and producer compares its timestamp with consumer's timestamp and send the missing content.

Is above hypothesis correct?

Looking for response please.
