no. 1 example

[0024] This embodiment provides an adaptive method for network transmission medium and rate, figure 1 is the flowchart of the method, such as figure 1 As shown, the method includes the following processing:

[0025] Step 101: Obtain all destination IP addresses of the device;

[0026] Step 102: Obtain all transmission media and transmission rates supported by the device, and send probe request messages to all destination IP addresses in all combinations of all transmission media and all transmission rates;

[0027] Wherein, in this embodiment, all transmission media and transmission rates supported by the device may be specifically acquired according to factory attribute parameters of the device itself.

[0028] In this embodiment, preferably any of the following protocols can be used to send the probe request message: ARP (Address Resolution Protocol, Address Resolution Protocol), ICMP (Internet Control Message Protocol, Internet Control Message Protocol) and BFD (Bidirecti...

no. 2 example

[0036] In this embodiment, the signaling interaction between the device and the gateway is combined with the attached figure 2 Here is a brief description of the network transmission medium and rate adaptation method provided by the present invention.

[0037] Such as figure 2 As shown, firstly, the device collects its destination IP address pool, that is, stores all its destination IP addresses in the destination IP address pool.

[0038] The device traverses all transmission media and their rates, and sends an ARP detection request message to the destination IP address pool through the gateway.

[0039] After receiving the response packet of the ARP detection request, the device records the medium and rate of the network port corresponding to the response packet, and the network port negotiation succeeds.

[0040] It should be noted that the network transmission medium and rate adaptation method provided by the present invention can use other protocols exemplified in the...

no. 3 example

[0042] In this embodiment, the specific solution of the present invention is described by using the ARP protocol to send the probe request as an example.

[0043] The adaptive method for network transmission medium and rate provided in this embodiment mainly includes the following processing:

[0044] The base station equipment generates the destination IP address pool through configuration files, etc.;

[0045] Traverse all the transmission media and their rates supported by the device, and send an ARP detection request message to the destination IP address pool.

[0046] If the device can receive the ARP response message, record the transmission medium and its rate at this time, and the port medium and rate negotiation is successful. If the traversal ends and no ARP response message is received, expand the destination IP address pool to include all IP addresses that belong to the same network segment as the IP address of the local device (excluding the local IP address), an...

Abstract

The present invention provides an adaptive method, device and equipment for network transmission medium and rate, which are used to solve the problem in the prior art that the physical connection of the equipment in actual use does not match the default parameter settings, resulting in the inability to send and receive messages normally For the problem, the method includes: obtaining the protocol IP address of the interconnection between the destination networks owned by the device; obtaining all the transmission media and transmission rates supported by the device, and using the transmission media and the transmission rate to form all Combining sending detection request messages to all the destination IP addresses; receiving detection request response messages, recording the transmission medium and transmission rate corresponding to the detection request response messages, and this scheme gets rid of the configuration of the port medium and rate. Reliance saves the manpower for configuration and the cost of base station downstation, and improves the reliability of port transmission medium and transmission rate adaptation.

Description

technical field [0001] The invention relates to the communication field, in particular to an adaptive method, device and equipment for network transmission medium and rate. Background technique [0002] There are many kinds of transmission media for current Ethernet transmission equipment. For example, there are mainly electrical ports and optical ports at present; there are also many kinds of transmission rates, which have a certain relationship with the transmission medium. The current transmission rate ranges from 10M to 10G, etc. . In Ethernet transmission, if the devices connected at both ends of the link have the same transmission medium and rate, the two can communicate normally; if the configuration parameters (media or rate) of the devices at both ends are inconsistent, the port will fail to negotiate successfully. Or there is an error in the negotiation state, resulting in an abnormality in sending and receiving packets. Some current equipment (such as base stati...
