[Ndn-interest] Fixed window size for interests in ndnfs or PyNDN like ndncatchunks

Hello Ishita,

In the following project, we implemented a SegmentStream which sends multiple interest for segments and assembles the received segments in order. Here is the method which responds to receiving a new segment:

It uses a utility class which represents the names in a namespace (like the names of segments) and keeps track of whether an interest was sent and the content of the received data packet.

Here is an example from that project that uses the utility to fetch a file from memoria.ndn.ucla.edu which is running NDNFS.

To optimize interest pipeline often depends on the application. For example, the NDN RTC (video streaming) has code to adjust the number of interest based on the video rate, etc.

Hi All,

Has anyone implemented the fixing of a window size for interest packet requests (rather than having one interest sent out per data packet sequentially, as is the case in ndnfs and PyNDN) like in ndncatchunks?

The ndnfs paper mentions having implemented a fixed-size pipeline mechanism in their paper, but I was unable to find any such ndnfs client on the ndnfs-port github repo. It would be great if someone has any information regarding this and can point me to any relevant information.
