Protocol Descriptions

The Blue Heat/Net Sync supports a variety of protocols. The following is a brief explanation of

each and how they are implemented.

ARP

Address Resolution Protocol, a method used to find a unit‟s Ethernet MAC address from its

Internet address.

BOOTP

Bootstrap Protocol, a protocol that allows a unit to boot from the network instead of using

information stored on the Blue Heat/Net Sync (typically in Flash memory).

DHCP

Dynamic Host Configuration Protocol, a protocol that provides a means to dynamically

allocate IP addresses to computers on a local area network. The system administrator assigns

a range of IP addresses to DHCP and each client device on the Local Area Network requests

an IP address from the DHCP server. The request and grant process uses a lease concept with

a controllable time period. The Blue Heat/Net Sync offers this as a configurable option; it

can either be turned on or the user can set a fixed IP on the unit.

HTTP

HyperText Transfer Protocol, a standardized Protocol that Web Browsers use to connect to

web pages. It is used to provide web based configuration tools on the Blue Heat/Net.

IP Internet Protocol, a common addressing scheme for modern networks. Used in conjunction

with TCP to form TCP/IP (see below)

RARP

Reverse Address Resolution Protocol, a method to find a unit‟s Internet address from a MAC

or Ethernet address.

TCP

Transmission Control Protocol, a lossless protocol, requiring a handshake to insure that data

is not lost during transmission. Used in TCP/IP to form the main data transfer pathway

between Blue Heat/Net Sync units and the host computer.

Telnet

A terminal-protocol that can be run over TCP/IP to connect to a remote unit. It is one of the

methods used to configure the Blue Heat/Net Sync unit.

TFTP

Trivial File Transfer Protocol, a protocol used to download firmware to the Blue Heat/Net.

UDP

User Datagram Protocol, a protocol used when handshake is not critical. It is used by TFTP

(see above) and for auto discovery of the units.
