Problems solved by technology

[0003] However, since the switching access part and the edge switching part, and between the edge switching part and the central switching part are interconnected by high-speed duplex SerDes serial links, each link is interconnected, due to the influence of physical factors , there is a large delay difference
When this type of delay difference is not considered, when a new switching unit is added to the switching access part, edge switching part or central switching part, the links between the switching unit and the newly added switching unit are not fully connected. In this case, it will exchange data with the newly added switching unit, so that the switching unit will have more data in and less out in a certain period of time.
However, the buffer absorption capacity of each level of switching units in the switching system is limited, so the asymmetrical congestion problem of more inflows and less outflows will be caused due to the delay difference, and then the newly added switching unit, or the newly added The switching unit connected with the link between the switching units sends a back pressure signal to other switching units in the switching system to block the ingress flow, thereby affecting the normal data exchange of the switching system

Embodiment 1

[0053] This embodiment provides a congestion management method for a switching network, such as image 3 As shown, the method includes the following steps:

[0054] Step 101: Calculate a first difference between the current time and the time when the second switching unit receives the latest first route broadcast message sent by the first switching unit.

[0055] The first route broadcast message refers to the confirmation that the first switching unit sends to the second switching unit through the link after confirming that any link between the first switching unit and the second switching unit is connected. Link up message. The first switching unit and the second switching unit are routers, and the first switching unit and the second switching unit belong to the same distributed routing cluster system, that is, a cluster router. In this embodiment, the first switching unit is used to restart, and after the newly added or existing first switching unit in the switching syste...

Embodiment 2

[0128] Based on the same inventive concept as the foregoing embodiments, this embodiment provides a congestion management device for a switching network, such as Figure 5 As shown, the device includes: at least one processor 20 and a memory 21 for storing computer programs that can run on the processor 20; wherein, Figure 5 The processor 20 shown in the figure is not used to indicate that the number of processors is one, but only used to indicate the positional relationship of the processor relative to other devices. In practical applications, the number of processors can be one or more a; similarly, Figure 5 The memory 21 shown in FIG. 3 also has the same meaning, that is, it is only used to refer to the positional relationship of the memory relative to other devices. In practical applications, the number of the memory may be one or more.

[0129] Wherein, when the processor 20 is used to run the computer program, the following steps are performed:

[0130] calculating a...

Embodiment 3

[0169] The present embodiment will be described in further detail below through a specific example, Image 6 It is a schematic diagram of the restart of the switching unit. When the switching access unit A1# is restarted, as shown in Image 6 As shown by the bold dotted line with two-way arrows in , the switching access unit A1# performs route transfer with the edge switching units B1# and B2# respectively, so as to establish a route to the edge switching units B1# and B2 respectively in the switching access unit A1# The routing path of #, and set up the routing path towards switching access unit A1# in edge switching unit B1# and set up the routing path towards switching access unit A1# in edge switching unit B2#; Then, edge switching unit B2 #Respectively carry out routing transmission with switching access unit A2#, switching unit C3# and switching unit C4#, so that switching access unit A2#, switching unit C3# and switching unit C4# update the information to switching acce...

Abstract

The invention discloses a method for managing congestion in a switching network. The method includes: calculating a first difference between the current time and the time when the second switching unit receives the latest first route broadcast message sent by the first switching unit; When it is determined that the first difference satisfies the first time threshold, based on the first route broadcast message received up to the current time, update the routing table of the second switching unit between the second switching unit and the Routing paths between the first switching units. The invention also discloses a congestion management device and a computer storage medium of the switching network at the same time.

Description

technical field [0001] The invention relates to the congestion management technology of the switching network, in particular to a congestion management method, device and computer storage medium of the switching network. Background technique [0002] The switching system is a key component of the packet switching equipment, and it usually consists of a three-level switching part, a switching access part, an edge switching part and a central switching part. Among them, between the switching access part and the edge switching part, between the edge switching part and the central switching part are all connected by high-speed duplex serial deserializer (SerDes, Serializer-Deserializer) serial links to transmit physical data. [0003] However, since the switching access part and the edge switching part, and between the edge switching part and the central switching part are interconnected by high-speed duplex SerDes serial links, each link is interconnected, due to the influence...
