Caching protocol:
A separate cache service is implemented external to MF click router and talks with the router through network socket.
The following packet types are defined:
enum PktType {
REQ_PKT, Request packet received REQ_ACK, Request ack sent out: hit or miss REQ_RESP, Cached data sent for a request DATA_PKT_C, Data packet received for caching DATA_RESP,
};
The message flow of caching is shown in the attached figure.
