A set of rules applied to data transmission procedures over network. Major
Protocol
communication protocols include:
FTP: File Transfer Protocol. This is a communication protocol or protocol-
•
implemented commands to provide file transfer between a host and
clients over TCP/IP network.
DHCP: An upward compatible protocol of BOOTP. This communication
•
protocol allocates a dynamic IP address to each client machine upon
communication startup on TCP/IP network and collects the allocated IP
address when communication is completed. The server allocates one of
multiple IP addresses and notifies the setup information to a client.
BOOTP: A communication protocol to automatically load setup
•
information including IP address and a domain name from the server to a
client on TCP/IP network.
RARP: A communication protocol to request IP address information via
•
the network adaptor address (MAC address) of a client.
IPP: A communication protocol to execute remote printing between the
•
print server and clients via Internet.
TCP/IP: A standard communication protocol required to access to

Internet and other large-scale network.
Proxy Server Provides functions to store data fetched from remote servers. When a
user request to display a web page that has been displayed and stored
in the proxy, the proxy server read the stored data but does not access
the remote server where the original page is present, for efficient access
services. When a proxy server receives a URL from a PC, it searches the
file in the cache and sends it to the PC if the requested file is found. If the
requested file is not stored in the cache, it accesses the remote server of
the URL to acquire the file and, at the same time, stores the acquired file
in the cache so that the proxy server can quickly send the file at the next
request.
Redistribution module A built-in module of an application created with SDK. Applications without
this module cannot work on MEAP platform.
