Both icn packet generator client and server are are part of the +cicn-plugin for vpp. The topology should be similar to the following: + +vpp1 (PG client) <--> vpp2 (cicn-plugin) <--> vpp3 (PG server) + +vpp2 is the node that we are going to benchmark. + +The current packet generator client requests subsequent content to the packet +generator server. Interest and content name is the following: + +ccnx:/ccnxpg/<Chunk_number> + +The Chunk number (u64) is iteratively incremented after an interest is issued. + + +CONFIGURATION +Vpp1 must contain a pg interface (e.g., pg0) configured +with the IP address 192.168.128.245 and be able to forward packet to +192.168.128.1. The following configuration takes care of setting the pg +interface, setting 192.168.128.1 reachable through the pg interface and the icn +pg client. It assume that the next cicn hop answer to the ip 192.168.128.2 and +it is reachable through a local interface with the ip address +192.168.128.3. There ip addresses can be set arbitrarily, modifications must be +done in both vpp1 and vpp2. IMPORTANT: In the following example, the port 33301 +is used to pass packets to the icn pg client plugin. Modification to such port +requires to change the packet definition on the icn-pg file. + +vpp# exec <path-to>/icn-pg +vpp# set int ip addr pg0 192.168.128.245/24 +vpp# cicn pgen client port 33301 src 192.168.128.3:33301 dest 192.168.128.2:6363 + +To run the icn_pg packet generator script configure vpp as follows. + +vpp# packet-generator enable + +Following the example, Vpp2 must be set to be reachable to the ip address +192.168.128.2 and have a face +192.168.128.2:6363<-->192.168.128.3:33301. Moreover vpp2 must be able to forward +packets (and interest) to the packet generator server. + +Vpp3 configuration is simple. It must be configured to accept packets from +vpp2. The cicn packet generator plugin can be configured in this way: + +vpp# cicn pgen server port 6363 size 1200
