20130205043 | ETHERNET-COMPATIBLE METHOD AND SYSTEM - A data transmission method compatible with an Ethernet, an Ethernet protocol translation gateway, a node server and an Ethernet-compatible communication system are provided to solve the problem of a new type of network. The new type of network is a network with centralized control function. The Ethernet protocol translation gateway can access the new type of network and obtain from a node server therein the media access control (MAC) address of the Ethernet protocol translation gateway and the MAC address of terminals bound to the Ethernet protocol translation gateway. Therefore, a data packet to be transmitted from the new type of network to an Ethernet can be forwarded to a target terminal in the Ethernet according to the MACs of the terminals, by means of the MAC of the Ethernet protocol translation gateway and the MAC of the target terminal being added to the packet. Likewise, for a data packet transmitted from the Ethernet to the new type of network, the packet can be forwarded to the new type of network according to the destination address of the new type of network in the packet by means of removing from the packet the MAC of the Ethernet protocol translation gateway and the MAC of the target terminal. Thereby, the convergence of the new type of network and the Ethernet is achieved. | 08-08-2013 |
20130201990 | METHOD AND SYSTEM OF ACCESSING NETWORK FOR ACCESS NETWORK DEVICE - A method for an access network device to access a network is disclosed, which comprises: powering on an access switch, and setting in its internal downlink protocol packet address table that all downlink protocol packets are to be oriented to a CPU module; receiving, by the access switch, a downlink protocol packet sent from a node server and orienting the downlink protocol packet to the CPU module of the access switch, and generating, by the CPU module, an uplink protocol packet and sending the uplink protocol packet to the node server, wherein the downlink protocol packet contains an access network address that is to be allocated; sending, by the node server, a network access command to the access switch, wherein the network access command contains an access network address of the access switch, and the access network address is the access network address to be allocated; and updating, by the access switch, its internal downlink protocol packet address table, as orienting only a protocol packet with a destination address being its own access network address to the CPU module. The present invention can guarantee a stable transmission rate of the data packet transmission and avoid time delay, thereby guaranteeing the quality of the network transmission. | 08-08-2013 |
20130201987 | SERVICE COMMUNICATION METHOD AND SYSTEM FOR ACCESS NETWORK APPARATUS - A service communication method for an access network apparatus. The access network apparatus comprises a source terminal and a target terminal both connected to the same access switch. The method comprises: a node server, according to a request of a current service, notifying the access switch connected to both the source terminal and the target terminal to set a downlink port of the access switch, to which a data packet of the current service is directed, in an internal data packet address table thereof; the source terminal sending an uplink data packet of the current service; and after receiving the data packet, the access switch directing the data packet to the corresponding downlink port according to the setting of the internal data packet address table thereof, and transmitting the data packet to the target terminal through the downlink port. The present invention can effectively save the bandwidth and routing resources, ensure a steady and smooth transmission path, avoid delay of multimedia services, satisfy national information security requirements, and save hardware resources, thereby ensuring network transmission quality. | 08-08-2013 |
20130188519 | COMMUNICATIONS METHOD AND SYSTEM FOR COMMUNICATIONS OF NETWORK ACCESSING EQUIPMENT - A method for communication link for an access network device. The access network device comprises: a node server, an access switch, and a terminal. The method comprises: the node server requesting for a protocol packet on the basis of a service initiated by the source terminal; acquiring a piece of communication link information of the current service, and the communication link information comprises a piece of communication port information for the node server and the access switch involved in the current service; on the basis of the communication port information for the node server, the node server setting up within an internal data packet address table the port directed by the data packet of the current service; on the basis of the communication port information for the access switch, transmitting to the corresponding accessing switch a port configuration command; on the basis of the port configuration command, the accessing switch setting up the port directed by the data packet of the current service within an internal data packet address table. By means of the present invention, the stability of a transmission channel is ensured, thereby avoiding delays for multimedia services. | 07-25-2013 |
