Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flowchart of a link aggregation method provided by an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
step S110, collecting port configuration information of the first network element port and the second network element port.
Respectively acquiring port configuration information of a first network element port and port configuration information of a second network element port, where the port configuration information may include: port rate information, duplex mode information, and negotiation mode information, among others.
Step S120, determining whether the port configuration information of the first network element port is consistent with the port configuration information of the second network element port.
Step S130, if the port configuration of the port is not consistent with the port configuration of the local port, generating an adaptation notification message, and sending the adaptation notification message to the first network element port and the second network element port, so that the first network element port and the second network element port determine, according to the adaptation notification message, that the port configuration of the other port is consistent with the port configuration of the local port.
And/or generating an adaptation command of the port configuration, and sending the adaptation command to the first network element port or the second network element port, so that the first network element port or the second network element port modifies the port configuration of the port according to the adaptation command to adapt to the port configuration of the other port.
In this embodiment, when the port information of the first network element port is inconsistent with the port configuration information of the second network element port, the port configuration of the first network element port and the port configuration of the second network element port are adapted, so that the first network element port and the second network element port can perform link aggregation.
Specifically, on the one hand, an adaptation notification message is generated and sent to the first network element port and the second network element port. Wherein, the adaptation notification message is used to notify the network element that the port configuration of the other port is consistent with the port configuration of the port. That is, after the first network element port receives the adaptation notification message, it is determined that the port configuration of the second network element port is consistent with the port configuration of the local terminal according to the adaptation notification message. And after the second network element port receives the adaptation notification message, determining that the port configuration of the first network element port is consistent with the port configuration of the port according to the adaptation notification message. Briefly, a first network element port and a second network element port are made to consider the port configurations of each other as consistent by sending an adaptation notification message to the first network element port and the second network element port.
And on the other hand, generating an adaptation command of the port configuration, and sending the adaptation command to the first network element port or the second network element port. The adaptation command is used for controlling the network element port to adapt and modify the configuration of the network element port. After receiving the adaptation command, the first network element port modifies the port configuration of the first network element port to adapt to the configuration of the second network element port; and after receiving the adaptation command, the second network element port modifies the port configuration of the second network element port to adapt to the configuration of the first network element port.
It follows that the adaptation described in this embodiment involves two implications: first, by sending notification messages to two network element ports, the two network element ports are made consistent for each other's port configuration. And secondly, the configuration of the first network element port and the second network element port is adapted by issuing an adaptation command.
Step S140, the first network element port and the second network element port are interconnected to form a group port in link aggregation.
Through step S130, the port information of the first network element port and the second network element port is adapted, and at this time, the first network element port and the second network element port can perform link aggregation, and the first network element port and the second network element port are interconnected to form a pair of group ports in link aggregation.
According to the link aggregation method provided by the embodiment, port configuration information of a first network element port and port configuration information of a second network element port are collected and compared, if the port configuration information of the first network element port is inconsistent with the port configuration information of the second network element port, the first network element port and the second network element port consider that the port configurations of the first network element port and the second network element port are consistent or directly adapt the port configurations of the first network element port and the second network element port by means of issuing an adaptation notification message and/or issuing an adaptation command, so that the first network element port and the second network element port are adapted, the two adapted network element ports are interconnected, and a group of ports in link aggregation is formed. The method adapts the configuration of two incompatible network element ports, and the two network element ports after adaptation become a group of ports which can share service in link aggregation, thereby realizing the link capacity expansion of a non-differential uninterrupted network, reducing the condition of adding link aggregation between different ports of different equipment, and solving the problem that the two incompatible network element ports in the prior art can not form a group of ports in link aggregation; meanwhile, the mode does not need to replace equipment or board cards, is easier to implement, does not need to cut services, and ensures that the services are not interrupted.
Fig. 2 shows a flowchart of a link aggregation method according to another embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
step S210, collecting port configuration information of a first network element port and a second network element port, where the port configuration information includes: port rate information, duplex mode information, and negotiation mode information.
Step S220, determine whether the port configuration information of the first network element port is consistent with the port configuration information of the second network element port.
Respectively judging whether the port rate information of the first network element port is consistent with the port rate information of the second network element port; judging whether the duplex mode information of the first network element port is consistent with the duplex mode information of the second network element port; and judging whether the negotiation mode information of the first network element port is consistent with the negotiation mode information of the second network element port.
Step S230, if the port rate information is not consistent, generating an adaptation notification message, and sending the adaptation notification message to the first network element port and the second network element port, so that the first network element port and the second network element port determine, according to the adaptation notification message, that the port rate of the other port is consistent with the port rate of the port.
If the port rates of the first network element port and the second network element port are not consistent, generating an adaptation notification message, sending the adaptation notification message to the first network element port, and determining that the rate of the second network element port is consistent with the rate of the first network element port by the first network element port according to the adaptation notification message; and the second network element port determines that the rate of the first network element port is consistent with the rate of the port according to the received adaptation notification message. Briefly, a first network element port and a second network element port consider port rates of each other to be consistent by sending an adaptation notification message to the first network element port and the second network element port.
For example, the rate of the port of the first network element is 100M, the rate of the port of the second network element is 1000M, and the rates of the two are not the same. Then a first notification message for notifying that the rate bandwidth of the second network element port is 100M is generated and sent to the first network element port, and after the first network element port receives the first notification message, it is determined that the rate of the second network element port is also 100M and is consistent with the rate of the port. And generating a second notification message for notifying that the rate of the first network element port is 1000M and sending the second notification message to the second network element port, wherein after the second network element port receives the second notification message, the rate of the first network element port is also 1000M and is consistent with the rate of the port.
Step S240, determining a target bandwidth utilization rate according to the port rate of the first network element port and the port rate of the second network element port, generating a notification message of the target bandwidth utilization rate and sending the notification message to the network element port with a higher port rate, so that the network element port with the higher port rate sets the highest bandwidth utilization rate thereof as the target bandwidth utilization rate according to the notification message.
And determining the target bandwidth utilization rate according to the rate of the first network element port and the rate of the second network element port, generating a notification message of the target bandwidth utilization rate, sending the notification message to the network element port with higher rate, and setting the highest bandwidth utilization rate of the network element port with higher rate as the target bandwidth utilization rate according to the notification message.
Alternatively, the target bandwidth utilization is equal to the quotient of the value of the lower-rate bandwidth and the value of the higher-rate bandwidth. Following the above example, the maximum bandwidth utilization X1 of the first network element port is set as the default 100% in advance, and the maximum bandwidth utilization X2 of the second network element port is set as the default 100%, the rate bandwidth of the first network element port is 100M, the rate bandwidth of the second network element port is 1000M, and the target bandwidth utilization X is 100M/1000M is 10%. The notification message of the target bandwidth utilization rate X is sent to the second network element port (the network element port with the higher rate), and the second network element port sets the highest bandwidth utilization rate X2 to 10% according to the notification message, so as to prevent the situation that the utilization rate of the second network element port exceeds 10%, which results in the utilization rate of the second network element port exceeding 100%. And sending a notification message of the highest bandwidth utilization rate X1 (100%) to the first network element port. It can be seen that the present embodiment is directed to the rate of the network element port, and the high rate port is adapted to the low rate port.
Step S250, if the duplex mode information is inconsistent, and one of the first network element port and the second network element port is in a full duplex mode, and the other network element port is in a half duplex mode, generating a duplex mode modification command, and sending the duplex mode modification command to the half duplex mode network element port, so that the half duplex mode network element port can modify the half duplex mode into the full duplex mode according to the duplex mode modification command.
If the duplex mode of the first network element port is inconsistent with that of the second network element port is judged, and the duplex mode of one network element port is determined to be the full duplex mode and the duplex mode of the other network element port is determined to be the half duplex mode according to the collected duplex mode information, a duplex mode modification command is generated and sent to the network element port in the half duplex mode, and the network element port in the half duplex mode is modified into the full duplex mode according to the received modification command. Briefly, for the duplex mode, the embodiment forces the half-duplex mode to issue the full-duplex mode.
Step S260, if the negotiation mode information is inconsistent, and one of the first network element port and the second network element port is in the auto-negotiation mode, and the other network element port is in the full duplex mode, generating a port adaptation command, and issuing the port adaptation command to the network element port in the auto-negotiation mode, so that the network element port in the auto-negotiation mode adapts the network element port in the full duplex mode according to the port adaptation command.
If the negotiation mode information of the two network elements is not consistent, one network element port is determined to be in an auto-negotiation mode according to the negotiation mode information, and the other network element port is in a full duplex mode, a port adaptation command is generated and issued to the network element port in the auto-negotiation mode, and the network element port in the auto-negotiation mode adapts the port configuration of the network element port in the full duplex mode according to the port adaptation command. Briefly, this embodiment is directed to a network element port in auto-negotiation mode, and the port configuration of the network element port is adapted to a network element port in full duplex mode.
It should be noted that, the adaptation process for the three different port configurations may be performed serially according to a predetermined sequence, or may be performed in parallel, which is not limited by the present invention.
According to the link aggregation method provided by the embodiment, port information including a port rate, a duplex mode, a negotiation mode and the like, which is obtained by interconnecting a first network element and a second network element, is collected; by controlling the high-rate port to adapt to the low-rate port, the auto-negotiation mode to adapt to the full-duplex mode and the half-duplex mode to forcibly send the full-duplex mode, port link aggregation under different rates, duplex modes and negotiation modes between two network elements is realized, link capacity expansion without difference and network interruption is realized, and interruption of important services such as financial services and security services can be guaranteed.
