Fig. 2 is a flowchart illustrating a method for switching a monitoring traffic forwarding path according to the present application; as shown in fig. 2, the method includes:
in step 205, the new primary monitor notifies each monitoring switch to switch the monitoring traffic forwarding path.
Fig. 3 is a schematic diagram of an embodiment of switching a monitoring traffic forwarding path by a virtual supervisor provided in the present application, so as to automatically switch an uplink of the network monitoring switch shown in fig. 1.
In fig. 3, monitor 1 and monitor 2 interact their initial device priorities through VRRP protocol, monitor 1 receives the initial device priority of monitor 2, determines the device priority lower than that of the device, and sets the role of the device as the master monitor role, monitor 2 receives the initial device priority of monitor 1, determines the device priority higher than that of the device, and sets the role of the device as the slave monitor role.
The monitor 1 sends a protocol message, such as a gratuitous arp (address resolution protocol) message, to the monitoring switches 3 and 4, and notifies that the MAC address of the IP address of the virtual monitor is the MAC address of the monitor 1. The monitoring switches 3 and 4 receive the protocol message, learn the MAC address of the virtual monitor to the port connected to the monitor 1, and send the uplink audio and video traffic to the virtual monitor to the monitor 1 through the port connected to the monitor 1.
The monitor 1 calculates delay and packet loss rate monitoring according to the received uplink audio and video traffic, and determines whether the session is abnormally failed. The monitor 1 monitors the failed sessions and counts the number of failed sessions. When the number of newly added fault sessions counted by the monitor 1 reaches a predetermined increment value, for example, 20 newly added fault sessions (the predetermined increment value is not limited in the present application, and the predetermined increment value may be increased or decreased according to the network and service sensitivity requirements); and modifying the device priority according to a predetermined decrement value (which is not limited in the application), and reducing the device priority of the device.
And when the monitor 1 and the monitor 2 interact with the VRRP protocol message, sending the modified equipment priority. The monitor 2 transmits the initial device priority of the present device.
The monitor 1 receives the initial device priority of the monitor 2, determines the modified device priority lower than the device, and then keeps the device role as the master monitor role, and the monitor 2 receives the modified device priority of the monitor 1, determines the device priority higher than the device, and then keeps the device role as the slave monitor role.
Fig. 4 is a schematic diagram of another embodiment of switching a monitoring traffic forwarding path by a virtual monitor according to the present application;
the monitor 1 continues to receive upstream audio and video traffic, monitor for failed sessions, and count the number of failed sessions. When the number of newly added failure sessions counted by the monitor 1 by the number of failure sessions reaches the predetermined incremental value 20 again, the monitor 1 modifies the device priority according to the predetermined incremental value, and lowers the device priority of the present device.
And when the monitor 1 and the monitor 2 interact with the VRRP protocol message, sending the modified equipment priority. The monitor 2 transmits the initial device priority of the present device.
The monitor 1 receives the initial device priority of the monitor 2, determines that the modified device priority of the device is equal to the device priority of the opposite side, and then keeps the device role as the role of the master monitor, and the monitor 2 receives the modified device priority of the monitor 1, determines that the modified device priority is equal to the device priority of the device, and then keeps the device role as the role of the slave monitor.
Fig. 5 is a schematic diagram of another embodiment of switching a monitoring traffic forwarding path by a virtual monitor according to the present application. The monitor 1 continues to receive upstream audio and video traffic, monitor for failed sessions, and count the number of failed sessions. When the number of newly added failure sessions counted by the monitor 1 by the number of failure sessions reaches the predetermined incremental value 20 again, the monitor 1 modifies the device priority according to the predetermined incremental value, and lowers the device priority of the present device.
And when the monitor 1 and the monitor 2 interact with the VRRP protocol message, sending the modified equipment priority. The monitor 2 sends the initial device priority.
The monitor 1 receives the initial device priority of the monitor 2, determines the modified device priority higher than the device, and switches the device role of the device to be the slave monitor role, and the monitor 2 receives the modified device priority of the monitor 1, determines the device priority lower than the device, and switches the device role of the device to be the slave monitor role.
The monitor 2 sends gratuitous ARP messages to the monitoring switches 3 and 4, informing the MAC address of the IP address of the virtual monitor to be the MAC address of the monitor 2. The monitoring switches 3 and 4 receive the protocol message, learn the MAC address of the virtual monitor to the port connected with the monitor 2, and switch to the forwarding path connected with the monitor 2 through the uplink audio and video flow sent to the virtual monitor.
The monitor 2 is used as a main monitor of the virtual monitor, and automatically modifies the priority of the device according to the embodiments of fig. 3 to 5, and the uplink forwarding path switching for automatically switching the monitoring traffic can be realized after the number of fault sessions is increased. It should be noted that, if the priority of the two devices of the virtual monitor is alternately lowered due to too many fault sessions, so that after the master monitor and the slave monitor are switched many times, when the priorities of the two devices are both at a sufficiently low value (zero or a predetermined minimum value), it indicates that there is a fault that needs to be eliminated in the network, and the network administrator only needs to perform troubleshooting, and then the switching is not performed according to the above embodiment.
The method and the device have the advantages that the automatic adjustment of the priority of the equipment of the VRRP protocol message is triggered after the monitoring of the increase of the fault session is finished, so that the automatic switching of the master monitor and the slave monitor of the virtual monitor is carried out, the monitoring switch automatically switches the uplink forwarding paths of the uplink audio and video flows, and the problem of manual switching is avoided.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
