Fig. 1 is a kind of flow chart of the transmitting method of COM1 provided in an embodiment of the present invention.Communication ends shown in Fig. 1 The transmitting method of mouth can be in the case where the first COM1 be passed through virtual machine, by the level of first COM1 The second COM1 in connection equipment automatically passes through virtual machine.This method comprises the following steps.
Step S11, when the first COM1 of host is passed through into virtual machine, the first of the first COM1 of extraction Port information.
Wherein, method provided by the invention can apply to be provided with the host of virtual machine, and host can be electricity The equipment such as brain, interchanger or router.At least there is a COM1 on host, COM1 can be USB port, when So, or other kinds of port.
The port information of COM1 can be different information according to different situations.If for example, on host The Bus number of all COM1s is identical, then the port information of COM1 can be port numbers.And for example, if on host That the Bus number of a COM1 differs with the Bus number of another port be present, then the port letter of COM1 Breath can include Bus number and port numbers.
In the case of the Bus number identical of all COM1s on host, by the first COM1 of host When passing through virtual machine, the first port information of extraction is port numbers.For example, it is assumed that there are 3 COM1s on host, point Not Wei port x1, port x2 and port x3, wherein, port x1 port numbers are p1, and port x2 port numbers are p2, port x3's Port numbers are p3, and virtual machine A is provided with host.When the port x1 of host is passed through virtual machine A by user, host Need extraction port x1 port numbers p1.
In the case of being differed on host in the presence of the Bus number of a COM1 with the Bus number of another port, So when the first COM1 of host is passed through into virtual machine, it is necessary to extract the first end message of the first COM1 Breath, now, first port information includes Bus number and port numbers.For example, it is assumed that there are 3 COM1s, respectively on host For port x1, port x2 and port x3, wherein, port x1 port numbers are p1, and port x1 Bus number is b1, port x2 end Slogan is p2, and port x2 Bus number is b2, and port x3 port numbers are p3, and port x3 Bus number is b3, is set on host It is equipped with virtual machine A.When the port x1 of host is passed through virtual machine A by user, then host needs to extract port x1's Bus number is b1 and port numbers p1.
First COM1 is the COM1 on host, and the first COM1 refers to passing through on host virtually The COM1 of machine, the quantity of the first COM1 are at least one.For example, it is assumed that there are 3 COM1s on host, point Not Wei port x1, port x2 and port x3, virtual machine A is provided with host, if port x1 is passed through virtual machine by user A, then the first COM1 is port x1；If port x1, port x2 and port x3 are passed through virtual machine A by user, then First COM1 is port x1, port x2 and port x3.
Method provided by the invention can apply in different technology scenes.For example, method provided by the invention can be with In the scene interacted applied to user with host.And for example, method provided by the invention can also be applied to network controller with In the interaction scenarios of the network equipment, wherein, the network equipment is host.
In the scene that user interacts with host, if user needs the first COM1 of host passing through void Plan machine, then user can utilize input equipment to input the instruction that the first COM1 is passed through to virtual machine to host.In place Main frame receive user using input equipment to host input when the first COM1 is passed through into the instruction of virtual machine, place First COM1 can be passed through virtual machine by main frame according to the instruction, so that virtual machine can monopolize the first COM1.
In the interaction scenarios of network controller and the network equipment, network manager can control net by network controller Network equipment.If network manager needs the first COM1 of the network equipment passing through virtual machine, then network manager Network controller can be utilized to send the instruction that the first COM1 is passed through to virtual machine to the network equipment.Received in the network equipment To network manager using network controller to the network equipment send when the first COM1 is passed through into the instruction of virtual machine, First COM1 can be passed through virtual machine by the network equipment according to the instruction, so that virtual machine can monopolize the first communication ends Mouthful.
Step S12, the port information of each COM1 in host is obtained.
Wherein, after the first port information that host extracts the first COM1, host also needs to obtain host The port information of each COM1 in machine.Each COM1 refers to all COM1s on host in host.
For example, it is assumed that when port information is port numbers, there is 3 COM1s, respectively port x1, end on host Mouthful x2 and port x3, wherein, port x1 port numbers are p1, and port x2 port numbers are p2, and port x3 port numbers are p3, place Virtual machine A is provided with main frame.When the port x1 of host is passed through virtual machine A by user, then host needs to extract Port x1 port numbers p1.Then, host also needs to obtain port numbers p1, p2 and p3 of each COM1 in host.
Step S13, determined in the port information of all COM1s of host and first port information match Second port information, the second COM1 corresponding to second port information are the communication ends of the cascade device of the first COM1 Mouthful.
Wherein, after the port information of each COM1 during host obtains host, host is needed all The second port information with first port information match is determined in the port information of COM1.Second port information refers to It is the port information with first port information match, the quantity of the second COM1 is at least one.
If the second COM1 is cascaded on the first COM1, then the port of all COM1s on host The second port information of the second COM1 can be included in information, and second port information can have one with first port information Fixed similitude.For example, when port information is port numbers, then first port information is first end slogan, and second port is believed Cease for second port number, it is assumed that first end slogan is p1, and second port number is p1.3, it is identical in that first end slogan and second The prefix part of port numbers is p1, and distinctive points are that second port number has suffix portion .3, and first end slogan is without after Sew part.
Therefore, method provided in an embodiment of the present invention can inquire and first in the port information of all COM1s The prefix part of port information it is identical and with suffix portion second port information, now, can with learn second port believe Second COM1 corresponding to breath is the COM1 of the cascade device of the first COM1.
Due to determining the second port information with first port information match in the port information of all COM1s A variety of concrete implementation modes be present, two ways is briefly described below.Certainly, it is not limited to following two modes.
First way, when the port information of COM1 is port numbers, in the port information of all COM1s It is determined that it may comprise steps of with the second port information of first port information match：First, in all COM1s The port numbers of prefix part identical the 3rd with first end slogan are determined in port numbers.Then, determine to contain in the 3rd port numbers There is the second port number of suffix portion.
Below by the implementation procedure of for example bright first way.For example, it is assumed that port information is port numbers, host There are 3 COM1s on machine, respectively port x1, port x2 and port x3, wherein, port x1 port numbers are p1, port X2 port numbers are p2, and port x3 port numbers are p3, and virtual machine A is provided with host.Assuming that user connects on the x1 of port Meet a cascade device USB hub, and there is 2 ports, respectively port x4 and port x5 on the USB hub USB hub, Port x4 port numbers are p1.1, and port x5 port numbers are p1.2.The port x1 of host is passed through into virtual machine A in user When, host needs to extract port x1 port numbers p1.Then, host also needs to obtain each COM1 in host Port numbers p1, p2, p3, p1.1 and p1.2.Now, host determines in all port numbers p1, p2, p3, p1.1 and p1.2 With port numbers p1 prefix part p1 identical port numbers p1, p1.1 and p1.2.Then, in port numbers p1, p1.1 and p1.2 It is determined that second port p1.1 and p1.2 containing suffix portion.
The second way, when the port information of COM1 includes port numbers and Bus number, in all COM1s Determine to may comprise steps of with the second port information of first port information match in port information：First, all The 4th port information of the Bus number with first port information is determined in the port information of COM1.Then, at the 4th end The prefix part identical fifth port information with the port numbers of first port information is determined in message breath.Finally, at the 5th end The second port information containing suffix portion is determined in the port numbers of message breath.
Below by the implementation procedure of for example bright second way.For example, it is assumed that port information include Bus number and Port numbers, there is 3 COM1s, respectively port x1 and port x2 on host, wherein, port x1 port information includes Port numbers p1 and Bus number b1, i.e. b1-p1；Port x2 port information includes port numbers p1 and Bus number b2, i.e. b2-p1, place Virtual machine A is provided with main frame.Assuming that user is connected to a cascade device USB extended line, and cascade device on the x1 of port There is 1 port on USB extended lines, be port x3, port x3 port information includes port numbers p1.1 and Bus number b1, i.e., b1-p1.1.When the port x1 of host is passed through virtual machine A by user, host needs to extract port x1 port information b1-p1.Then, host also needs to obtain port information b1-p1, b2-p1 and b1- of each COM1 in host p1.1.Now, host is determined in all port information b1-p1, b2-p1 and b1-p1.1 with port information b1-p1 Bus number b1 port information b1-p1 and b1-p1.1.Secondly, host is determined in port information b1-p1 and b1-p1.1 and Port information b1-p1 port numbers p1 prefix part p1 identical port informations b1-p1 and b1-p1.1.Finally, host exists The port information b1-p1.1 containing suffix portion .1 is determined in port information b1-p1 and b1-p1.1 port numbers p1 and p1.1.
