Detailed Description

The packet generator is made of two entities, a client and a server. The client issues interests at high speed and the server satisfy each interest it receives with the corresponding data. The packet generator is made of three nodes:

• hicnpg-interest that receives packets from a packet generator interface and manipulate them to generate interests based on the given configuration. This node runs at the client side.
• hicnpg-data that receives data packets at the client side and counts them. This is useful for statistics. The "show err" command will give the number of interest issued and data received at the client side
• hicnpg-server that recevies and interest and replies with the corresponding data. The data is generated from the interest switching the src and destination address in the packet and appending a payload to the packet.

These three nodes are inserted in the vlib graph in the following manner:

• hicnpg-interest is added as a possible next node of the pg-input node. The packet generator stream then specifies it as next node.
• hicnpg-data is added as next hop of the ip4/6-unicast node exploiting the corresponding feature and it runs before the ip4/6-inacl node. In this way, every packet that is received through an interface on which this feature is enabled is sent to this node.
• hicnpg-server is added as next hop of the ip4/6-unicast using the corresponding feature and it runs before the ip4/6-inacl node. In this way, every packet that is received through an interface on which this feature is enabled is sent to this node.

An example of how to use the pg for hicn is available in the documentation.
