Hi ~
I'm working on reproducing your NetCache implementations. According to the code on master branch, it seems no bitmap implementations. Since the value length is 128 bytes (generated by the default python script) and the p4src/value.p4 logic just put the 128 bytes value into 32*4 register arrays.
Can you supply a bitmap implementation (including the controller logic) described in the paper ?

Hi,I am running this netcache p4 code, but I have got a question.
In the heavy_hitter count process, when the count reached at threshold, you use clone_egress_pkt_to_egress function to create a packet and send this new packet to Controller.
I thought this new packet will not enter the parser and ingress , because it is cloned to egress.
But it seems not like this, the packet marked as HOT_READ_REQUEST enter the switch from the parser, and I dot't know why.
This is different from the P4-14 specification.
Thank you.

I run the ./run_demo.sh
it start the mininet successfully , but it doesn't work well in the demo , i follow the instruction to start all the *.py in the correct host , the server and the client didn't got anything . I try to use the p1 ping p2 in the mininet , but failed.
I check the output of ./run_demo.sh I find this thing

I think it is for ['/home/ubuntu/bmv2/targets/simple_switch/sswitch_CLI', 'netcache.json', '22222']
My ubuntu environment is the P4 provided entire .ova.

I am a china student with poor english . This my email : [email protected] Thank you very much.

Did you open the source code for Tofino ASIC? Because the paper's testbed is forTofino Switch. It will be very kind of you if you could give me some advices.
