Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The inventor finds after deliberation, be provided with a multi-core CPU in the existing route device on interface board, multi-core CPU comprises a main core and a plurality of physics core, if main core monitors any one physics nuclear state in same multi-core CPU when being down state, master control borad determining interface board status in router is abnormal, and interface board is no longer processed business.Yet this moment, other states were that the physics of upstate endorses to satisfy the service operation requirement.If interface board is not processed business, can increase the traffic load of the normal interface board of state, reduced traffic rate and resource utilization, even can cause communication failure.
In order to address the above problem, the embodiment of the present invention provides a kind of interface board state detection method, the method flow diagram of the embodiment of the present invention as shown in Figure 1, described interface board state detection method comprises:
S101: monitoring is positioned at the state of each physics core of same multi-core CPU in router, determines that state is that the physics core of upstate is available physical core.Wherein:
The state that monitoring is positioned at each physics core of same multi-core CPU in router is to receive by periodicity the logon message that physics core sends, and whether receives in read-around ratio is preset in judgement that logon message realizes.If receive logon message in default read-around ratio, determine that the state of physics core is upstate, physics core is defined as available physical core.If do not receive logon message in default read-around ratio, determine that the state of physics core is down state, physics core is defined as unavailable physics core.Default read-around ratio can be 3 times or other values, can determine according to the different application scene, and this is not limited.
Physics core send logon message mode can for: each physics core arranges the heartbeat inspecting timer that an inside is provided with the time interval, and each physics core sends logon message every the time interval.The time interval can be set as different values according to the different application scene, and this is not limited.
S102: the Reconfigurations relation mapping table, described configuration relation mapping table is used for recording the corresponding relation of Logic Core and available physical core, and in the configuration relation mapping table after renewal, Logic Core is checked with available physical successively and is answered.
The configuration relation mapping table is set up when interface board starts at every turn, is used for recording the corresponding relation of Logic Core and available physical core, and wherein, the number of Logic Core is identical with physics core number in multi-core CPU.When starting, giving tacit consent to all physics cores is available physical core, therefore, initial configuration relationship map table record be the corresponding relation of Logic Core and all physics cores, and be one to one.
The renewal of configuration relation mapping table can any one physics nuclear state changes to down state or real-time update when the upstate monitoring, namely monitoring any one physics nuclear state when upstate changes to down state or change to upstate from down state, real-time update configuration relation mapping table.
In configuration relation mapping table after renewal, Logic Core is checked with available physical successively and is answered.As: a multi-core CPU has physics core 1, physics core 2, physics core 3 and physics core 4.The corresponding physics core 1 of Logic Core 1, the corresponding physics core 2 of Logic Core 2, the corresponding physics core 3 of Logic Core 3, the corresponding physics core 4 of Logic Core 4 in the configuration relation mapping table when initial.Be down state when monitoring 1 Status Change of physics core, Reconfigurations relation mapping table is with the corresponding physics core 2 of Logic Core 1, the corresponding physics core 3 of Logic Core 2, the corresponding physics core 4 of Logic Core 3.If the Status Change that again monitors physics core 2 is down state, Reconfigurations relation mapping table again is with the corresponding physics core 3 of Logic Core 1, the corresponding physics core 4 of Logic Core 2.If the Status Change that monitors again physics core 1 is upstate, the Reconfigurations relation mapping table is with the corresponding physics core 1 of Logic Core 1, the corresponding physics core 3 of Logic Core 2, the corresponding physics core 4 of Logic Core 3.
