Voice (VoIP) Gateway Networking Module
The Fusion Networking Module is the core component that the VoIP Terminal Adapter Module and the Router Gateway Module rely upon. Most components have a TBD value for the HEAP usage. However all of the networking modules use the heap from the networking stack. The heap setting can vary from 32 Kbytes to about 100 Kbytes depending on the application.
This module includes the following components
- DHCP Client
- DHCP Server
- DNS Resolver
- FTP Client
- FTP Server
- NAT
- PPP
- PPPoE
- SNMP V2 & V3
- SNTP
- Core Net Stack TCP/UDP/IGMP
- TFTP Client
DHCP Client
The Fusion DHCP (Dynamic Host Control Protocol) Module allows a network to automatically configure itself. The main responsibility for the DHCP Client is to obtain an IP address.
DHCP Server
The Fusion DHCP Server centralizes the allocation of IP addresses on a network or the Internet. It may also allocate other configuration options as specified in RFC 2131 and RFC 2132.
DNS Resolver
The Fusion DNS (Domain Name System) software is a resolver comprised of a library of easy-to-use routines that a client application can call to perform the domain name to IP address translation function.
FTP Client & Server
The Fusion FTP (File Transfer Protocol) client and server allows the efficient sharing of files, programs or data between diverse host systems.
NAT / Firewall
The Fusion NAT (Network Address Translation) module allows client IP hosts on a private network to access Internet hosts without having to obtain a public IP address. The NAT module also works as an effective firewall.
PPP
The Fusion PPP (Point to Point Protocol) module is designed for serial links and provides a method of transmitting datagrams over serial point to point links. PPP is also the foundation that PPPoE relies upon.
PPPoE
The Fusion PPPoE (Point to Point over Ethernet) module is designed for serial links and provides a method of transmitting datagrams over serial point to point links over Ethernet. PPoE allows broadband Internet access (DSL) via bridged Ethernet, while preserving the traditional dial-up paradigm for assigning IP addresses to clients and performing authentication and billing.
SNMP
The Fusion SNMP (Simple Network Management Protocol) Module is designed to allow for management of networked devices. SNMP is extensible -- allowing users to easily add network management functions to their existing products. SNMP separates the management architecture from the hardware architecture, which broadens the overall use of SNMP.
SNTP
The Fusion SNTP (Simple Network Time Protocol) module offers client and server services to obtain and set accurate date and time values in network-connected devices.
Net Stack TCP+UDP+IGMP IP
The Fusion Networking TCP/IP Stack provides developers a 20-year history of networking standards compliance. The Fusion Net Stack is the most widely used networking protocol stack in the world, with tens of thousands of design wins and about a billion network-enabled products shipping.
TFTP
The Fusion TFTP (Trivial File Transfer Protocol) module allows for the efficient transferring of files between diverse host systems without the extended features and potential overhead associated with FTP. TFTP is often used for remote upgrades of firmware and changing device configuration files.

*A reference design is a sample electronics circuit design that shows engineers how to utilize the latest developments in microchips in their own products. Using a reference design as a base, it is possible today for a device manufacturer to incorporate a new technology into existing designs in a few weeks, and have products available to ship not long after.
