Embodiment Construction

[0029] The present invention will be further described below by accompanying drawings.

[0030]The overall structure of the media proxy device module of the present invention is shown in Figure 2, the structure of the media proxy general module is inside the dotted line, which can be transplanted into any system. It includes a forwarding module, an address table maintenance module, a parameter configuration module, and a registration module. The forwarding module is externally connected to the network port driver of the data link layer, and internally connected to the address table maintenance module. The address table maintenance module, The parameter configuration module and the registration module are also connected to each other respectively, the registration module is also connected to the IP protocol stack, and the parameter configuration module is also connected to the CLI module and the SNMP module externally.

[0031] The ARP spoofing module of the media proxy device ...

Abstract

The invention provides one method to realize VoIP business connection in same OLT of EPON, which sets media agent device in upper device of OLT, wherein, the media agent device realizes same OLT two ONU VoIP modules data pack transfer through ARP deception and data pack transfer type to realize VoIP business connection. The invention media agent device modifies these data composed of source MAC address and aims one to transfer the real needed data VoIP module.

Description

technical field [0001] The present invention relates to realize the VoIP (Voice over IP) service intercommunication technology of optical network unit (ONU) under the same optical line terminal (OLT) of Ethernet passive optical network (EPON), specifically relate to realizing the same OLT in EPON system Interworking of VoIP services. technical background [0002] In the EPON system, an OLT provides a Gigabit Ethernet port upstream, and provides an optical fiber downstream through an optical splitter (ODN) to separate 16 to 32 optical fibers, and each optical fiber is connected to an ONU device as an ONU Uplink port, ONU provides several 100 / 1000M Ethernet interfaces as user ports to connect VoIP module, user's computer, Ethernet switch, Ethernet router or other Ethernet devices. After the user data enters the user port of the ONU, the ONU uploads it to the OLT through the optical fiber, and the OLT does not exchange the data with other ONUs, but only sends it through the up...
