Embodiment 3:

In the related art, for the lw4o6 application, the A+P information of the user-side device may be obtained by using the Option option of the DHCPv6 protocol to obtain the information, and acquiring the DHCP 4o6 method (this is actually a dynamic IPv4 address). In the allocation mode, the IPv4 configuration parameters are independent of IPv6 by encapsulating the contents of the DHCPv4 message in the DHCPv6 message. The MAP_PORT_SET attribute of the PCP protocol is used to obtain the IPv4 address and a set of ports. Among them, the DHCP 4o6 mode is simple to interact, and it can also solve the defect of using the Option (option) of the DHCPv6 protocol. It has been the preferred technology in the lw4o6 scenario.

However, in the related art, the port resources obtained by the CPE through the DHCP 4o6 are fixed and limited. As the data service on the CPE increases, the port block resources are exhausted, and the subsequent CPE service development will be affected; The embodiment of the invention provides a method and a device for acquiring and allocating port resources on demand, which can solve the problem that the port resources are exhausted when the A+P information is distributed in the application of the DHCP 4o6 protocol in the related art, and By intelligently controlling the usage of the port, the actual usage of the port is improved, and the service performance of the lw4o6 scenario is improved.

The NAPT device belongs to the user side device and is responsible for address and port conversion when data is forwarded.

The port obtaining device belongs to the user side device and periodically monitors the port usage and is responsible for port application and release. When the port usage rate exceeds the first threshold Kmax, the port request request is initiated to the server, and when the port usage rate is detected to be lower than the first threshold Kmin, the port release request is initiated to the server;

The port allocation device belongs to the server and maintains the port information of the server, accepts the application and release of the port, and performs real-time statistics on the port usage of each IP address. When receiving the port information request, the port information of a unit is delivered. When the port information is released, the port information is maintained.

In the communication system shown in FIG. 3, the user side device 1 provided by the embodiment of the present invention includes:

The port monitoring module 41 is configured to periodically monitor the port usage, and is responsible for port application and release. It is equivalent to the combination of the acquisition module 11 and the management module 14 in the embodiment shown in FIG. When it is detected that the port usage exceeds the first threshold Kmax, a port request request is initiated to the server, and when the port usage rate is detected to be lower than the first threshold Kmin, a port release request is initiated to the server.

Port Maintenance Module 42: Set to save the current port usage.

NAPT module 43: Set to address and port conversion when data is forwarded.

Tunnel encapsulation module 44: Set to data encapsulation.

As shown in FIG. 3, the lw4o6 tunnel data forwarding process according to the embodiment of the present invention includes the following steps S301 to S305:

S301: The LAN side terminal user of the CPE sends an IPv4 service request.

S302: In the process of forwarding the CPE packet, the NAPT conversion is required. The NAPT module 43 requests the port maintenance module 42 for available port information;

S303: The port maintenance module 42 allocates available ports according to the current port usage; if no port is available, no allocation is performed;

S304: The NAPT module 43 performs processing according to the request result of the available port. If no port is available, the packet is discarded. If the port is available, the source IP address and source port are modified and the mapping relationship is recorded.

S305: The tunnel encapsulation module 44 performs IPv6 encapsulation on the IPv4 packet, and the CPE sends the IPv6 encapsulated packet to the IPv6 network, and finally the IPv6 decapsulation is performed by the AFTR server, and then forwarded to the IPv4 network.

As shown in FIG. 4, the interaction process between the CPE and the DHCP 4o6 server according to the embodiment of the present invention is periodically triggered by the port monitoring module of the CPE, and includes the following steps S401 to S406:

S401: The port monitoring module 41 detects that the port usage rate is greater than Kmax, and applies for available port information.

S402: The DHCP 4o6Server allocates an available port to the CPE.

S403: The port monitoring module 41 updates the port information to the port maintenance module 42;

S404: The port monitoring module 41 detects that the port usage rate is less than Kmin, and requests to release the port information.

S405: The DHCP 4o6Server responds;

S406: The port monitoring module 41 updates the port information to the port maintenance module 42.

Optionally, in a practical application, the port obtaining device can perform real-time monitoring by using a timer, and in the timing processing, first obtain the total number of ports currently allocated, and the number of ports currently used, to obtain the current port usage rate. K; the threshold Kmax (first threshold) and Kmin (second threshold) of the port usage rate may be set by a network management or a pre-configured manner; if K>Kmax, the port acquisition process is triggered; if K<Kmin, the port is triggered. Release the process.

Optionally, for the server, when the port allocation request is received, the server collects statistics on the port usage of the multiplexed IP address, and if there is a spare port resource block, allocates. If there is no spare port resource block, the port is not allocated: when the received port is reclaimed, the server reclaims some ports and updates the port usage of the multiplexed IP address in real time.

Optionally, for the user-side device, when the port is obtained, the method includes: sending a DHCP 4o6 request to the server, encapsulating the specified option, carrying the following information: “Reuse IP address request, port resource request”, and receiving DHCP 4o6 from the server.
