The components of this address are as follows:
■
The <IP hostname> is the destination client’s IP hostname.
■
The <UDPport num> is the destination UDP port number on which the client host
is awaiting data.
For example, the address of
host=cordelia,udpport=40000
specifies that data
be delivered to host
cordelia
at UDP port 40000.
The server must have available a name service (or appropriate entries in local
/etc/
hosts
and
/etc/ethers
) so that the client hostname can be resolved to the four-
byte IP address and the six-byte Ethernet address before data transmission begins.

Specifying Encapsulation
For all types of output links, you specify the encapsulation of the data for a
particular bit stream with the MSMC API ‘s
msmSetConnect()
function. You fill in
an instance of the
MsmConnect
structure before calling
msmSetConnect()
. This
structure contains an
encap
field, which holds a string. This field determines the
encapsulation that the server uses to deliver data to the client.
TABLE 7-1
lists the
strings used to specify different encapsulations.
