Virtual Server

You can designate virtual servers, e.g., a FTP, web, telnet or mail server, on your local
network and make them accessible to the outside world. A virtual server means that it is
not a dedicated server -- that is, the entire computer is not dedicated to running on the
public network but in the private network.

VPI (Virtual Path Identifier) & VCI (Virtual Channel Identifier)

A VPI is a 8-bit field while VCI is a 16-bit field in the ATM cell header. A

VPI

identifies a link

formed by a virtual path and a

VCI

identifies a channel within a virtual path. In this way,

the cells belonging to the same connection can be distinguished. A unique and separate
VPI/VCI identifier is assigned in advance to indicate which type of cell is following,
unassigned cells, physical layer OAM cells, metasignaling channel or a generic broadcast
signaling channel. Your ISP should supply you with the values.
