help to understand cache

[server4all]

I all,
I need a little help to really understand what exactly means the data on multics cache like in this image...

requests - this are made by our peers to our server?
replies - are those the replies that peer gets from our server?
sent req - those are the request that our server makes to that peer?
sent rep - are those the request that our server gets from that peer?

i need to understand this part cause i have some peers that have a huge amount of request(1034077) and replies(1034077) and sent req (185358) and sent rep (608742)
and all of this for a 770 cache hits... This data is for 1 cache peer in high traffic day (weekend)... 1 day only

Replies is how many keys replays are came from the server
Requests is how many requests keys are made from the server

Cache lines with hude req and rep. are making huge UDP traffic
Depending from your cache configuration (CACHE SENDREQ, CACHE FORWARD and e.t.c.), cache time (in green) named ping is most important for cache this is min. time of any key that is coming from this cache line.
You can have huge req and rep numbers but do not have any hits, hits are coming from your users not from other cache lines
