When the synchronous serial ports of the central device and the edge device are configured to be the same link protocol, the central device and the edge device can communicate with each other, the detection and configuration work of the interface of the edge device is automatically completed, and then the work of forwarding service data and the like is undertaken.
However, in practical applications, the link protocols configured on the synchronous serial ports of the central device and the edge device may not be consistent, for example: the link protocol configured by the synchronous serial port of the central equipment is an FR protocol, while the link protocol configured by the synchronous serial port of the edge equipment newly added into the network is a PPP protocol, and the central equipment and the edge equipment cannot communicate with each other. In this case, in the prior art, the link protocol to be configured for the serial port of the edge device is generally determined manually, and then configuration is performed. If the edge devices are scattered or remote, the workload of network management personnel is increased, and the work of completing automatic interface configuration and forwarding service data by the edge devices is delayed.

Detailed Description
In order to make the purpose and technical solution of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
The basic idea of the invention is: the edge device negotiates with the central device, determines the configured link protocol of the serial port of the central device according to the negotiation result, and then determines the link protocol to be configured by the serial port of the edge device as the configured link protocol of the serial port of the central device.
Figure 1 shows a flow chart of the present invention. As shown in fig. 1, the method for determining a link protocol to be configured for a serial port of an edge device according to the present invention includes the following steps:
step 101: the edge device determines the configured link protocol of the serial port of the central device through negotiation with the central device.
Step 102: the edge device determines the link protocol configured by the serial port of the central device as the link protocol to be configured by the serial port of the edge device.
In the present invention, the methods for the edge device to negotiate with the center device are mainly divided into two types: one is that the edge device sends negotiation request message to the central device directly; another kind starts the negotiation process between the self serial port and the central device, and sends the negotiation request message in the negotiation process.
The first negotiation method is realized in detail as follows: the edge device sends a negotiation request message of a link protocol supported by a serial port of the edge device to the central device, receives a negotiation response message returned from the central device, and determines the link protocol configured by the central device according to the received negotiation response message.
For the edge device, the serial port of the edge device can generally support multiple link protocols, but only one of them is the link protocol configured by the serial port of the center device. In order to determine the configured link protocol of the central device, the edge device needs to send negotiation request messages of multiple link protocols supported by its serial port to the central device respectively. When a negotiation response message returned from the central equipment is received, the negotiation response message is respectively analyzed through a plurality of link protocols supported by the serial port of the central equipment, and if a certain link protocol is successfully analyzed, the link protocol configured by the serial port of the central equipment can be determined to be the link protocol which is successfully analyzed.
For the central equipment, whether the serial port supports various link protocols or not, the central equipment analyzes the received negotiation request message only according to the link protocol configured by the serial port, and if the analysis is successful, the central equipment returns a corresponding negotiation response message; otherwise, discarding the received negotiation request message.
The second type of negotiation method is specifically implemented as follows:
a1, edge device selects a link protocol as current link protocol in the link protocol supported by its serial port;
a2, configuring the current link protocol as the link protocol of the serial port of the current link protocol;
a3, the edge device starts the link negotiation process with the center device according to the link protocol configured by its serial port, and starts the timer;
a4, judging whether there is a negotiation response message from the central device in real time in the process of timing by the timer, if so, closing the timer, determining that the current link protocol is the link protocol configured by the serial port of the central device, and then exiting the process; otherwise, when the timer reaches the preset time value, reselecting a link protocol as the current link protocol, and then executing step a 2.
For the edge device, the edge device configures a certain link protocol for its serial port, and then starts the negotiation process with the central device. The negotiation process of each link protocol may be different, but each link protocol sends its own negotiation request message to the central device in the negotiation process, and if a returned negotiation response message is received, the edge device may determine that the link protocol currently configured by its serial port is the link protocol already configured by the serial port of the central device. If the negotiation response message is not received within the preset time period, determining that the currently configured link protocol of the serial port is not the link protocol configured by the central equipment, configuring another link protocol for the serial port, restarting the negotiation process, and the like until the negotiation response message returned from the central equipment is received.
For the central equipment, as with the first method, the central equipment still analyzes the received negotiation request message only according to the link protocol configured by the serial port of the central equipment, and returns a corresponding negotiation response message if the analysis is successful; otherwise, discarding the received negotiation request message.
In order to better explain the scheme of the present invention, the following describes a method for configuring a link protocol for an edge device serial port by using a preferred embodiment.
Example one
In this embodiment, the serial port of the edge device may support four link protocols, namely PPP, FR, HDLC and LAPB, where the PPP link protocol is designated as a default link protocol, and the other three link protocols are standby link protocols; the serial port described in this embodiment is a synchronous serial port. Of course, in practical applications, the edge device may only support any two or three combined link protocols, and may also support other link protocols, and as to which link protocols the edge device specifically supports, it will not be described in detail here.
Fig. 2 shows a flow chart of the first embodiment. As shown in fig. 2, the method for determining a link protocol to be configured for a serial port of an edge device in this embodiment includes the following steps:
step 201: the edge device configures the default link protocol as the link protocol of its own serial port, and starts the link negotiation process with the center device according to the default link protocol.
The default link protocol of the edge device serial port may be specified according to a link protocol normally configured for the center device serial port. Under the condition, if the serial port of the edge device is configured according to the default link protocol, the edge device receives the returned negotiation response message in the negotiation process with the central device, the link protocol configured by the serial port of the central device can be determined to be the default link protocol, and the negotiation response message does not need to be analyzed according to the standby link protocol, so that the link protocol to be configured by the serial port of the edge device can be quickly determined.
Of course, the edge device may not specify a default link protocol, and may not configure the serial port, and this step may be omitted.
Step 202: the edge device sends the negotiation request message of the standby link protocol to the central device.
In practical applications, the methods for sending negotiation request messages of different link protocols may be different. Such as: for the HDLC link protocol, as no negotiation process exists, the edge device only needs to send a KEEPALIVE message; for the LAPB link protocol, because of the existence of the two types of the module 8 and the module 128, the edge device needs to simultaneously send an SABM message for the module 8 and an SABME message for the module 128 to the center device; for the FR link protocol, local internetwork interface (LMI) messages need to be sent. In addition, since the LMI message has three non-standard types, namely, International Telecommunication Union (ITU), American National Standards Institute (ANSI), and CISCO, the three types of LMI message need to be sequentially transmitted.
Step 203: the edge device starts a timer.
Since a packet loss may occur during the negotiation between the edge device and the central device, a timer is usually set in the edge device. If the edge device does not receive any returned negotiation response message within the set time period, the edge device may resend the negotiation request message to the central device.
In practical application, if packet loss does not occur, the timer may not be set.
Step 204 to step 205: the edge device judges whether there is a negotiation response message from the central device in real time in the process of timing by the timer, if so, step 206 is executed; otherwise, when the timer reaches the preset time value each time, the negotiation request message of the standby link protocol is sent to the central device again, and then the step 204 is returned.
Step 206 to step 208: the edge device analyzes the received negotiation response message through the default link protocol, and judges whether the analysis is successful, if so, the edge device determines that the link protocol configured by the central device is the default link protocol, and then the step 210 is executed; otherwise, step 209 is performed.
Step 209: the edge device analyzes the negotiation response message sequentially through each standby link protocol, and determines the standby link protocol successfully analyzed as the link protocol configured by the central device.
The negotiation response message received by the edge device may be a response message returned by the central device for PPP negotiation in the PPP link negotiation process, or a negotiation response message received after the edge device sends a FR, HDLC, and LAPB negotiation request message. That is, the edge device may receive any one of the PPP, FR, HDLC, or LAPB link protocols to negotiate a response message.
If receiving PPP negotiation response message, edge device will successfully resolve PPP negotiation response message according to PPP link protocol configured by its own serial port, and confirm that central device is configured with PPP link protocol.
If other types of negotiation response messages are received, the received negotiation response messages can be analyzed by FR, HDLC and LAPB link protocols in sequence, and the negotiation response messages belonging to which link protocol are determined according to the analysis result, so that the link protocol configured by the serial port of the central equipment is determined.
Of course, if the edge device does not specify a default link protocol and does not configure the default link protocol for its own serial port, then, after receiving the negotiation response message, the edge device needs to sequentially analyze according to PPP, FR, HDLC and LAPB link protocols. The sequence of analyzing the received negotiation response message by PPP, FR, HDLC and LAPB link protocols can be determined by the user applying the scheme of the invention.
Step 210: the edge device closes the timer.
By applying the scheme of this embodiment, the edge device may send a negotiation request message of a link protocol supported by its serial port to the center device, and determine the link protocol configured by the serial port of the center device through the returned negotiation response message.
In practical application, if the edge device determines that the link protocol configured by the serial port of the central device is the same as the default link protocol configured by the serial port of the edge device, the edge device can directly perform communication.
If the edge device determines that the link protocol configured by the serial port of the central device is a certain self standby link protocol, after the timer is closed, the edge device configures the standby link protocol as the link protocol of the self serial port, so as to communicate with the central device.
Example two
In this embodiment, the serial port of the edge device may support four link protocols, namely PPP, FR, HDLC, and LAPB, where the PPP link protocol is designated as a default link protocol, and the other three link protocols are standby link protocols. Of course, in practical applications, the edge device may only support any two or three combined link protocols, and may also support other link protocols, and as to which link protocols the edge device specifically supports, it will not be described in detail here.
FIG. 3 shows a flow chart of the second embodiment. As shown in fig. 3, the method for determining a link protocol to be configured for a serial port of an edge device in this embodiment includes the following steps:
step 301: the edge device selects PPP as the current link protocol.
As in the first embodiment, the default link protocol of the edge device serial port may be specified according to the link protocol normally configured for the center device serial port. Under the condition, if the default link protocol is used as the current link protocol and the serial port of the edge device is configured, the edge device receives the returned negotiation response message in the negotiation process with the central device, the link protocol configured by the serial port of the central device can be determined to be the default link protocol, and the link negotiation process between other standby link protocols and the central device does not need to be started, so that the link protocol to be configured by the serial port of the edge device can be quickly determined.
Step 302: the edge device configures the current protocol as the link protocol of the serial port of the edge device.
Step 303: the edge device starts a link negotiation process with the central device according to a link protocol configured by the serial port of the edge device, and starts a timer.
Step 304 to step 306: the edge device judges whether a negotiation response message from the central device exists in real time in the timing process of the timer, if so, the timer is closed, the current link protocol is determined to be the link protocol configured by the serial port of the central device, and then the flow is exited; otherwise, when the timer reaches the preset time value each time, the edge device reselects a link protocol as the current link protocol, and then executes step 302.
By applying the scheme of the embodiment, the edge device starts the link negotiation process with the central device in sequence from the default link protocol until receiving the returned negotiation response message. In this embodiment, since the edge device configures the link protocol for its serial port before the negotiation, the edge device may directly communicate with the center device after determining the link protocol configured for the serial port of the center device.
In addition, in practical application, a default link protocol may not be set, but one of the four link protocols PPP, FR, HDLC and LAPB may be selected as the current link protocol, and the negotiation sequence may be determined by the user applying the scheme of the present invention, which is not described herein again.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
