Claim Text:
1. A media gateway device, comprising: a master module, a switch module, at least one relay access module, and at least one media resource module; wherein the switch module comprises three independent Virtual Local Area Networks (VLANs): a first VLAN, a second VLAN, and a third VLAN; the relay access module, the master module and the media resource module are connected to the switch module through the first VLAN, the media resource module is further connected to the switch module through the second VLAN, and the switch module is connected to an external Internet Protocol (IP) packet network through the third VLAN; wherein the media gateway device further comprises a network layer static routing table that is configured to store: a Media Access Control (MAC) address corresponding to the second VLAN, an MAC address corresponding to the third VLAN, as well as an MAC address and an IP address corresponding to the media resource module; wherein the master module comprises a processor and a memory, wherein the processor is coupled to the memory comprising instructions which when executed by the processor cause the processor to perform a control management of the relay access module, the media resource module, and the switch module through the first VLAN; the switch module comprises a Lan Switch Chip for forwarding, through the third and second VLANs, a first data frame of the external IP packet network to the media resource module for a processing, according to the MAC address corresponding to the second VLAN, the MAC address corresponding to the third VLAN, as well as the MAC address and the IP address corresponding to the media resource module in the network layer static routing table; and wherein the media resource module comprises a digital signal processor and a memory, wherein the digital signal processor is coupled with the memory comprising instructions which when executed by the digital signal processor cause the digital signal processor to receive the first data frame and forward the first data frame to the relay access module; and to forward, through the second and third VLANs, a second data frame corresponding to the relay access module to the external IP packet network, according to the MAC address corresponding to the second VLAN, the MAC address corresponding to third VLAN, as well as the MAC address and the IP address corresponding to the media resource module in the network layer static routing table.
