As can be seen from the above steps, in the prior art, the IP signal cross scheduling management method only targets at one switch, and multiple switches need to be managed independently through multiple cross point scheduling, and cross-switch scheduling cannot be performed.
In order to solve the above technical problem, an embodiment of the present invention provides an IP signal cross point scheduling apparatus, as shown in fig. 2, where the IP signal cross point scheduling apparatus is applied to a leaf-spine network, where the leaf-spine network includes a spine switch and a plurality of leaf switches, the IP signal cross point scheduling apparatus is capable of selecting any leaf switch in the leaf-spine network as a source switch and a destination switch, and the source switch and the destination switch may be the same leaf switch or different leaf switches, so as to implement source and destination selection across switches.

In this embodiment, the IP signal cross point scheduling apparatus 300 further includes a user interaction interface through which a user can operate the functional modules of the IP signal cross point scheduling apparatus. As an example, the user interaction interface provided by the IP signal cross point scheduler is shown in fig. 4.
As shown in FIG. 4, different functional areas are provided in the user interface, each of which includes one or more controls therein. Briefly, the user interaction interface comprises an operation area and a display area, wherein the operation area comprises different function controls, the display area is used for displaying available switch ports, source signals and destination signals, the function areas are operated to perform screening display, the destination switch and the source switch exceed the display range of the interface and can be quickly selected through tabs, and a light beam is operated by a mouse in a cross point interface and points to the current source switch and the current destination switch. The established intersection is displayed within the interface and the intersection of the enabled destination lock is labeled with an icon.
And setting an active signal selection functional area in the user interaction interface, and setting an active switch selection control, a port selection control and a source flow selection control in the active signal selection functional area. The user can screen out the required source signal by operating the source switch selection control, the port selection control and the source flow selection control. When a user operates the source switch selection control, the port selection control, and the source flow selection control, the source signal determination module 301 can detect the user operation and determine a source switch from a plurality of leaf switches in the leaf network in response to the user operation.
And a destination signal selection functional area is arranged in the user interaction interface, and a destination switch selection control, a port selection control and a destination flow selection control are arranged in the destination signal selection functional area.

The destination switch and the source switch may be the same switch or different switches. If the user's requirement is that the IP signal scheduling needs to be performed for one switch, the source switch and the destination switch can be the same switch by operating in the source signal selection functional area and the destination signal selection functional area. If the user needs to perform IP signal scheduling for different switches, the source switch and the destination switch can be different switches by operating in the source signal selection functional area and the destination signal selection functional area.
After determining the source switch and the destination switch, the route determination module 302 is then required to determine a first route from the source switch to the spine switch and a second route from the spine switch to the destination switch.

The routing link rule may be flexibly set according to an application scenario, and the present invention is not limited herein. As an example, the routing link rule may be: determining the number of IP signals in each available first link, and taking the available first link with the number of IP signals meeting a preset condition as a first route, for example, taking the available first link with the minimum number of IP signals as the first route; and determining the number of the IP signals in each available second link, and taking the available second link with the number of the IP signals meeting the preset condition as a second route, for example, taking the available second link with the minimum number of the IP signals as the second route.

The routing link rule may also be: determining the number of IP signals and the broadband usage amount in each available first link, and taking the available first link with the number of the IP signals and the broadband usage amount meeting preset conditions as a first route, for example, taking the available first link with the number of the IP signals smaller than a first threshold value and the broadband usage amount smaller than a second threshold value as the first route; and determining the number of the IP signals and the broadband usage amount in each available second link, and taking the available second link with the number of the IP signals and the broadband usage amount meeting preset conditions as a second route, for example, taking the available second link with the number of the IP signals smaller than a third threshold value and the broadband usage amount smaller than a fourth threshold value as the second route.

Nat (network Address translation) refers to network Address translation.
The embodiment of the invention only occupies one bandwidth by copying the IP signals on the source exchanger and the spine exchanger, and can dispatch the IP signals to the target equipment from the spine exchanger when a plurality of target equipment need to share the same IP signal, thereby saving the routing bandwidth.

When the IP signal cross point scheduling device detects that a user clicks a target lock control, the IP signal cross point scheduling device locks a source switch and a target switch which are connected with the cross point, protects the cross point connection, does not allow switching or disconnecting the flow of the target switch, and performs other operations only by releasing the cross point locking function. And when the IP signal cross point scheduling device detects that the user clicks the search control, the IP signal cross point scheduling device searches the source switch and the destination switch selected by the user and displays a search result.
