Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
Fig. 1 is the schematic diagram of the network system of the embodiment of the invention, as shown in Figure 1, the network system of present embodiment comprises the network equipment 1 and the network equipment 2, and the network equipment 1 is connected with the network equipment 2 by Ethernet interface, for example, can the port of Ethernet interface with the network equipment 2 be linked to each other with netting twine.
Wherein, the Ethernet interface default configuration of the network equipment 1 can be become a specific operating rate mode m odel1, gigabit pattern for example, default configuration mode during power-up initializing can for example can be configured to model1 10,000,000 patterns, 100,000,000 patterns, gigabit pattern etc. by flexible operating, and notes this model1.
The network equipment 1 obtains the operating rate mode m odel2 of the port that is connected with the network equipment 2 by Ethernet interface, then model2 and model1 are compared, if model2 is consistent with model1, the port butt joint that Ethernet interface can be connected with the network equipment 2 was described, then do not change model1, if model2 and model1 are inconsistent, then that Ethernet interface is current operating rate mode m odel1 is revised as model2, be about to model1 2 assignment and give model1, the operating rate pattern of port of the network equipment of the operating rate pattern of Ethernet interface and access is consistent, guarantees that Ethernet interface normally sets up butt joint with the port of the network equipment that links to each other.
Then, the network equipment 1 is waited for netting twine plug next time again, the current operating rate mode m odel1 of the operating rate mode m odel2 of the port of the network equipment that other after the plug is connected and the network equipment 1 relatively, do like this is for the state after plugging each time can both be compared with last state, if promptly model2 and model1 are inconsistent, so just reconfigure the MAC layer working method of Ethernet interface according to model2, be about to model1 2 assignment and give model1, if model2 is consistent with model1, so just represent that the model2 of the new network equipment that connects of the network equipment 1 is the same with before operating rate pattern, does not just need to reconfigure.
Wherein, the network equipment 1 comprises: controller (CPU), medium access control (MAC) layer equipment and physical layer equipment (PHY), the MAC interface of MAC layer equipment can connect and compose Ethernet interface by style interfaces such as MII, GMII, SGMII and physical layer equipment (PHY), and PHY can be connected with the network equipment 2 by netting twine.When power-up initializing, CPU can be preconfigured to a certain specific operating rate pattern to the operating rate mode m odel1 of the MAC interface of MAC layer equipment, for example gigabit pattern, 100,000,000 patterns, 10,000,000 patterns etc., and write down this operating rate mode m odel1.
Wherein, PHY obtains the operating rate mode m odel2 of the port that is connected with the network equipment 2, and physical layer equipment PHY can produce a successful connection interruption simultaneously, and CPU is delivered in this interruption, and model2 is carried in this interruption.PHY preferably can select gigabit PHY for use.In addition, PHY is configured to adaptive model, have only when physical layer equipment PHY under adaptive model just can and connecting object to carry out code stream mutual.
CPU catches in this and has no progeny, the state model2 that the physical layer equipment PHY of Ethernet interface is obtained inquires about comparison immediately, if model2 is the same with model1, the port working rate mode model2 that shows the connecting object that the Ethernet interface of the network equipment 1 is current is consistent to the operating rate mode m odel1 of MAC layer equipment disposition in advance with CPU, so just need not the MAC interface is operated; If model2 is different with model1, then CPU carries out network interface unloading on the software to MAC layer equipment, and then the operating rate pattern of the MAC interface of the model2 configuration MAC layer equipment that arrives according to interrupt trap again, is about to the model2 assignment and gives model1.
Be example with the base station in the WIMAX system below, describe application example of the present invention in detail.
For performance and the throughput that improves the R6 mouth, preferably the MAC layer operating rate pattern configurations with the R6 mouth becomes the gigabit pattern, because no matter consider that the performance of gigabit pattern all is better than 100,000,000 and 10,000,000 patterns far away from transmission rate, transmission delay, transmission capacity various aspects.Therefore, must consider that a kind of mode is made a return journey dynamically, the operating rate pattern of the MAC layer equipment of configure R6 network interface in real time, make it when being connected the maximum performance advantage of performance, and when 100,000,000 link to each other with 10,000,000 ports, also can communicate normally with gigabit port.
Meanwhile, the PHY that links to each other with the MAC layer equipment of R6 mouth generally all has adaptation function, the operating rate pattern of the physical layer equipment PHY that obtains peer end of the connection alternately that it can be by code stream between the bottom hardware.Therefore, can utilize this characteristic of physical layer equipment PHY, allow PHY serve as a connected mode state capture person's role.Capture as PHY when between the port that is connected state variation taking place, remove to tell CPU on one's own initiative, CPU and then according to the state that it captures comes neatly the MAC layer equipment of R6 mouth is provided with.
Fig. 2 is the schematic diagram according to the application example of network system of the present invention.The base station 108 of this application example is equivalent to the above-mentioned network equipment 1 among the figure, for example can be the base station of the PICO indoor type of WIMAX system, and the CPU in the base station is integrated with MAC layer equipment, MAC layer equipment disposition two gigabit MAC interfaces.One of them MAC interface 103 connects one 100,000,000 PHY 105,100,000,000 PHY105 link to each other with PC in order to the debugging base station by netting twine, another MAC interface 102 connects a gigabit PHY 104, then gigabit PHY 104 connects R6 mouth as the base station by RJ45 connector, promptly be connected with switch by netting twine, switch is connected with IAD.
Should mainly be to realize when base station R6 mouth connects external switch equipment 107 with example, can be according to different switch device types, the state self-adaption of R6 mouth is arrived optimization model.When the port type of switch 107 was 100M, the R6 mouth can be arranged to 100,000,000 patterns automatically, when the netting twine that pulls out the R6 mouth, the R6 mouth was linked on the gigabit mouth of switch 107, and the R6 mouth can self adaptation be arranged to the gigabit pattern.
For example, in the PICO of WIMAX project, used the PPC series CPU8313 of Freesacle (Freescale company is to produce semi-conductive company) on the network time dissemination system TPS10, this CPU has carried two gigabit Ethernet mouths, i.e. MAC interface.Its MAC interface 1 has connected networked physics layer equipment PHY971, and MAC interface 1 is set as the MII interface modes, links to each other with CPU and debugs the base station; Its MAC interface 2 connects networked physics layer equipment PHYM88E1111 (the gigabit physical layer equipment that horse Weir company produces), MAC interface 2 is arranged to the gmii interface pattern, PHY88E1111 dynamically removes to learn the port status of its connecting object in the network connection procedure, feed back to CPU, make CPU dispose the state of MAC interface 2 in real time, exactly.Like this, in actual applications, can use this gigabit mouth of CPU neatly, at connecting object is under the situation of gigabit mouth, can bring into play the advantage of its gigabit mouth to greatest extent, and if connecting object is 100,000,000 mouthfuls, also can be with tsec (three-speed Ethernet controllers, three fast ethernet controllers) automatically adjust to 100,000,000, realize connecting normally.
