And I set the cs_size of NFDrouter from 1000 to 5000. (1000,2000,3000,4000,5000).<br>

How many chunks is your video file? It might not be much more than 1000.<span class=""><br>

Maybe remove the "-v". The console output might be the performance bottleneck.<span class=""><br>

I run one of the consumer first, after it finished, I run another one.<br>
<br>
the goodput of the first consumer is 5Mbit/s, the second one is random, sometimes higher than 5Mbit/s,and sometimes lower than 5Mbit/s. I think with the cache in the middle NFDtouter, the goodput of the second client could be better all the time, but it's not.<br>
<br>
And with the increase of the cs_size, there is not linear change of the clients' goodput.<br>
<br>
BTW, the ndncatchunks in the collapse more than half time when I run, and with messy code (cause the file is a video?) in the terminal. With the file (.txt), I got ERROR (retry(3).........).<br>
