A kind of apparatus structure schematic diagram for the treatment of message that Fig. 2 provides for the embodiment of the present invention.
Detailed description of the invention
The scheduler that the embodiment of the present invention provides is independent of processor.For example, scheduler can be the chip independent of processor.Scheduler and processor also can be the different hardware circuit of same chip.The processor that the embodiment of the present invention relates to can be single core processor, also can be polycaryon processor.
A kind of method flow diagram for the treatment of message that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the method that the present embodiment provides comprises:
102: the type of new message determined by scheduler, according to the type of message and the corresponding relation of priority, determine the priority of described new message.
Scheduler is used for Trigger processor and processes message.Scheduler is the parts in the network equipment.The network equipment can be router, switch, fire wall or load equalizer.New message can be the message that the network interface card of the network equipment receives.After network interface card receives new message, can by new packet storage in the internal memory of the network equipment.After network interface card receives new message, the mark of new message can be sent to scheduler by network interface card.For example, the mark of new message can be the physical address of new packet storage in internal memory or logical address.In addition, after network interface card receives new message, new message can be sent to scheduler by network interface card.Network interface card and scheduler can be physically separated devices.Network interface card and scheduler also can be integrated in a device.
After scheduler receives the mark of new message, new message can be obtained according to the mark of new message, and new message is resolved, thus determine the type of new message.In addition, after scheduler receives new message, directly can resolve new message, thus determine the type of new message.Such as, when new message is Internet protocol (Internet Protocol, IP) during grouping, scheduler can resolve the IP head in new message, and judge whether the type of new message is transmission control protocol (Transfer Control Protocol according to agreement (Protocol) field in IP head, TCP) message or User Data Protocol (User Data Protocol, UDP) message.After the type of new message determined by scheduler, according to the corresponding relation of the type of message and priority, the priority of new message can be determined.Such as, the type of message and the corresponding relation of priority can specify that the priority of TCP message is the highest, and the priority of UDP message is minimum.Priority is used to indicate the processed sequencing of dissimilar message.Priority is relevant to the type of message.The message that the message that priority is high is low prior to priority is processed.
104: described scheduler compares the height of the priority of the first message and described new message, described first message is the message that pre-treatment worked as by processor.
First message is the message that pre-treatment worked as by processor.For example, the first message can be the message of the last instruction processorunit process of scheduler.Scheduler can by sending mode instruction processorunit process first message of the first message to processor.Scheduler also can by sending mode instruction processorunit process first message of the mark of the first message to processor.Processor can obtain the first message by the mark of the first message.The mark of the first message can be the physical address of the first packet storage in internal memory or logical address.
