发明名称 Method and system of accessing network for access network device
摘要 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.

主权项 1. A method for an access network device to access a network, comprising: powering on an access switch, and setting, in a downlink protocol packet address table within the access switch, 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 according to the settings of the downlink protocol packet address table; 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 of the access switch is the access network address to be allocated in the downlink protocol packet received by the access switch; and updating, by the access switch, the downlink protocol packet address table within the access switch, as orienting, to the CPU module, only a protocol packet with a destination address being the access network address of the access switch; wherein, an address information table is further set inside the node server, in which address occupation information, device identification information and device resource information are recorded, the method further comprising: initializing the address information table when the node server is powered on, wherein the initializing comprises:filling the access network address of the node server in a blank item of the address information table, and marking the address occupation information as used;filling the device identification information as current node server; andfilling the device resource information as port information of the current node server, the method further comprising: updating the address information table according to setting of a downlink port to which each downlink protocol packet is to be oriented in a downlink protocol packet address table within the node server, wherein the updating comprises:filling an access network address, to be allocated, contained in each downlink protocol packet respectively into a blank item of the address information table, and marking the address occupation information as standby, the method further comprising: updating the address information table according to setting of a downlink port of other access devices to which a port downlink protocol packet is to be oriented, wherein the updating comprises:filling an access network address, to be allocated, contained in each port downlink protocol packet respectively into a blank item of the address information table, and marking the address occupation information as standby, the method further comprising: updating the address information table when the node server receives a network access command response sent by the access switch, wherein the updating comprises:marking the address occupation information in an item corresponding to the access network address of the access switch as used;updating the device identification information as current access switch; andupdating the device resource information as the port information of the current access switch and an access network address information of an access network device connected to a port of the current access switch, the method further comprising: updating the address information table when the node server receives a network access command response sent by a terminal, wherein the updating comprises:marking the address occupation information in an item corresponding to the access network address of the terminal as used;updating the device identification information as current terminal; andupdating the device resource information as the port information of the current terminal and an access network address information of an access network device connected to a port of the current terminal.
