DCP

Hi

Can anyone tell me the best way to link Cache 5.xx to DSM. I am
currently using DDP but I need to move one of the boxes across the
other side of a router and am told that DDP is not routable.
Also is DCP similar to DDP in the way that I can access globals on
another systems using [UCI,VGP].

Thanks

Jon

Have you considered GRE tunnelling?

DSM supports DDP over TCP/IP; I don;t know about Cache 5.xx (never used it).

I have heard that our routers (Cisco 6509) have the ability to tunnel
but this means nothing to me. Can DDP/DCP be tunnelled ?

Thanks

AFAIK the Catalyst 6500 Series are switches not routers. There may be
some layer 3 functionallity I'm not familiar with Cisco switches.

Tunneling is just a point-to-point link. A way to encapsulate
arbitrary packets inside a transport protocol.

In theory yes. Tunneling can handle AppleTalk, DECnet, and IPX so
unless there's something really peculiar about it you should be able
to do it.

DCP is similar to DDP in that respect, but keeps (up to a) 63 block local
network cache on the client, for each process. Note that the cache is not
shareable amongst other client processes. You should get greatly improved
read performance with DCP.

Note that there may be licensing costs involved depending on the existing
license types already in place.
