Embodiment 1

[0067] In one embodiment of the present invention, the embedded network terminal of the present invention can be a VoIP adapter, figure 2 is the structure diagram of the adapter. The VoIP adapter includes an embedded network application module 1, a DHCP server 2, a TCP / UDP protocol processing module 3, an IP protocol processing module 4, a routing function module 5, a PPP and PPPoE module 6, an Ethernet packet processing module 7, and an ARP Protocol processing module 8, grouping distinguishing module 9, network interface card module 10 (NIC, Network Interface Card), HUB / SWITCH module 11, also includes control module 12, calculation module 13 and subscriber line interface control module 14. Among them, the control module 12 and the calculation module 13 belong to the main control calculation function part, the subscriber line interface control module 14 belongs to the subscriber line function part, and the rest belong to the network function part.

[0068] The VoIP adapter h...

Embodiment 2

[0123] In yet another embodiment of the present invention, the embedded network terminal described in the present invention can also be an IP phone, and the IP phone is a combination of an existing phone and the VoIP adapter described in Embodiment 1, Figure 4 It is a system structure diagram of an IP phone. The implementation of the network function part and the main control computing function part of the IP phone is the same as the corresponding module of the VoIP adapter described in Embodiment 1, so it will not be described in detail in this embodiment. . In the user functions section, a handset 15 and a keypad 16 are added. The keyboard 16 and the handset 15 are connected to the control module 12 in parallel, and are connected in parallel with an external common telephone.

[0124] Among them, the keyboard 16 is used to provide the user with a dialing function. The earpiece 15 is used to provide the user with a call function, and an internal speaker replaces the ringer...

Abstract

The embedded type network terminal (ENT) includes embedded type network application module, DHCP server, module for processing TCP / UDP protocol, module for processing IP protocol, route function module, PPP and PPPoE modules, Ethernet packet process module, module for processing Ethernet packet, module for processing ARP protocol, module of network interface card, HUB / SWITCH modules, and packet distinction module. The invention also discloses method for implementing the route function of ENT. ENT does not need to use the route table to maintain information of network addresses, does not need to carry out conversion of network addresses (CNA) so that ENT does not need to carry out checkout, and recalculation brought by CNA. The invention realizes transparent routing function completely, prevents problems caused by CNA. Features are: low cost, and high efficiency.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for realizing the routing function in an embedded network terminal. Background technique [0002] With the development and popularization of Internet technology, more and more home users have enjoyed the services brought by the Internet, and with the development of embedded technology, many embedded network terminals have appeared in the family, such as set-top boxes, VoIP ( Voice over Internet Protocol) adapters, home routers, etc., providing data and voice services for home users. [0003] A variety of network protocols are involved in the interconnection communication process. Among them, the Internet Protocol (IP) is a network layer protocol, which includes addressing information and control information, and enables data packets to be routed in the network. The IP protocol is the main network layer protocol in the TCP / IP protocol suite. The User Datagram Protoc...
