I am using a Packet Capturing and Analysis Tool named as Cisco Joy for generating network flows. Here is the link: https://github.com/cisco/joy
So Joy is a Packet capturing and analysis tool which uses a configuration file to capture Packets on a network interface and return json files as output in a directory.
I have configured Cisco Joy with AF_Packet to generate the network flows.
So I have been trying to process the network packets using tcpreplay on a virtual network interface at a speed of 3 GBPS but Joy is not receiving the packets at the same speed.
Actual: 450889 packets (397930525 bytes) sent in 1.06 seconds
Rated: 374307598.1 Bps, 2994.46 Mbps, 424122.22 pps
Flows: 12701 flows, 11947.01 fps, 450298 flow packets, 591 non-flow
Statistics for network device: vth0
Successful packets: 450889
Failed packets: 0
Truncated packets: 0
Retried packets (ENOBUFS): 0
Retried packets (EAGAIN): 0
Packets Received from Cisco Joy: 260850
So Here tcpreplay sent over 400k packets but Cisco Joy received only around 260k.
I have changed the buffer size of the length in which the packets have been captured but still I didn't find any resolution from that so anyone have any clue about this?
