Detailed Description
The terminology used in the embodiments of the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein is meant to encompass any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. Depending on the context, moreover, the word "if" may be used to be interpreted as "at 8230; \8230when" or "when 8230; \8230when" or "in response to a determination".
In a blade box networking environment, a MonitorLink function is usually configured on an interconnection module, so that when an uplink fails, the flow is quickly switched to a standby link.
When a certain uplink fails, the uplink1 state changes, and when the exchange module monitors that the uplink1 state is down through the MonitorLink, the exchange module sets the downlink port down in a linkage manner, and a first MEZZ card port directly connected with the downlink port is also down, so that the operating system is started to switch the service on the first MEZZ card port to a second MEZZ card port. At this time, the traffic running on the other virtual port on the physical port is also affected and switched accordingly.
Link switching imposes normal traffic flow. Since the link switching is a whole physical line, the failed service may only be an uplink on one virtual port, and other uplinks through the virtual port of the physical line are not failed, so that the traffic flows running on other virtual ports on other physical ports are also switched.
In view of the above, the present disclosure provides a link switching method, a link switching apparatus, an electronic device, and a machine-readable storage medium to solve the problem of switching links between multiple services when a link of one service fails.
The specific technical scheme is as follows.
In one embodiment, the present disclosure provides a link switching method applied to a management unit of a knife box device, including: acquiring the state of each uplink port of an uplink port group of a virtual link; if the states of the uplink ports are off-line, marking the uplink port group of the virtual link as an off-line state; and if the state of the uplink port group of the virtual link is offline, marking all the virtual links which are the same as the downlink ports of the virtual link as offline states.
Specifically, as shown in fig. 1, the method comprises the following steps:
step S11, the state of each uplink port of the uplink port group of the virtual link is obtained.
And step S12, if the states of the uplink ports are all offline, marking the uplink port group of the virtual link as an offline state.
Step S13, if the state of the uplink port group of the virtual link is off-line, all the virtual links same as the downlink ports of the virtual link are marked as off-line states.
When all physical uplink ports associated with a certain virtual link are offline, it is indicated that the virtual link cannot work normally, and other virtual links identical to the virtual downlink ports of the virtual link belong to a service, and at this time, the service has function loss on the physical link, so all virtual links of the service are marked as offline for switching, and at this time, other virtual links not in the service are not affected.
In one embodiment, the upstream port group includes a plurality of upstream ports, and the upstream ports are physical ports.
In one embodiment, the virtual links of the same downstream port are included in the same virtual link set, and the virtual link set is associated with one service.
In one embodiment, if a virtual link of a virtual link set is marked as down, then the link of the traffic associated with the virtual link set is switched and only switched.
And performing linkage between the MEZZ card virtual port on the computing node and the uplink port of the interconnection module. When the uplink fails, all affected virtual links (computing nodes, MEZZ cards, physical ports and virtual ports) can be quickly positioned, so that the failed virtual links can be quickly and accurately switched under the condition that other normal virtual links of the same physical link are not affected.
The management unit of the knife box can sense the configuration and the state of all nodes and interconnection modules of the knife box.
A plurality of virtual links are constructed through the configuration of nodes and interconnection modules, each virtual link is marked by 1 uplink port group and 1 virtual downlink port, and the virtual downlink ports can be determined by node IDs, mezz card IDs, physical port IDs and partition IDs. That is, 1 virtual link can be uniquely determined by 5 elements of an uplink port group, node ID, mezz card ID, physical port ID, and partition ID.
All virtual links with the same virtual downlink port are defined as a virtual link set. That is, all the virtual links in a virtual link set are different in uplink port group, and the virtual downlink ports are the same.
In the uplink port group, if any uplink port is in an on-line up state or no uplink port exists, the marking state is up, otherwise, the marking state is down.
When the uplink port group state of a certain virtual link is up, marking the virtual link state as up, otherwise, marking the virtual link state as down.
When at least one virtual link in a certain virtual link set corresponding to one service is down, all other virtual links in the virtual link set are marked as down.
And controlling the state switching of the whole virtual link by changing the state of the uplink port group and using the instruction of the Mezz card to control the state of the virtual port.
That is, the management unit scans the states of all the upstream ports and the virtual links at a certain period, and updates the states of the upstream ports and the virtual links according to the above rules. When all the virtual links of the virtual link set corresponding to a certain service are marked as down, the link of the service is switched, and the links of other services are not switched, so that the problem that a plurality of services switch the links when one service link fails is solved.
