PrivateNavigate to the corresponding network port, according to the private network bandwidth B that comprises in the instruction
Private, utilize ACL (Access Control List (ACL)) with the private network flow restriction of fictitious host computer at B
PrivateNumerical value, be equivalent to IP thus
PrivateWith B
PrivateBind together, this moment, main frame can be with speed B
PrivateThe visit internal network;
103, the user can be to a public network address IP of control platform application at bandwidth device place inside and outside the management and control
Public, and be this public network address application public-network bandwidth B
Public, the inside and outside bandwidth device of management and control this moment need not switch or NAT device are sent instruction; Arrive IP in user applies
PublicAnd B
PublicAfter, by with above-mentioned platform alternately can be with IP
PublicBe tied on the fictitious host computer;
Control platform in above-mentioned 103 is existing part of the prior art, and because the user is same as the prior art to the process of this platform application public network address and bandwidth, namely belonging to is the application process of public network resilient ip address, therefore its process is not done narration more at this.
104, the inside and outside bandwidth device of management and control sends IP to NAT device
PublicBe converted to IP
PrivateInstruction, make fictitious host computer can pass through IP
PublicThe visit public network;
Because existing public network address all is deployed on the NAT device (from the embodiment of the invention 103 in can also be like this), and finishes public network address to the conversion of private net address by NAT device, thus in present embodiment 104 NAT device specifically with IP
PublicBe converted to IP
PrivateProcess do not give unnecessary details.
105, the public network flow velocity of the inside and outside bandwidth device control of management and control NAT device restriction fictitious host computer is at public-network bandwidth B
PublicScope in.
Particularly, the inside and outside bandwidth device of management and control comprises IP at least to the instruction of the public network flow velocity of NAT device transmission restriction fictitious host computer in this instruction
PublicAnd B
PublicAfter NAT device is received this instruction, according to IP
PublicFind the inside and outside bandwidth device of management and control to want the public network address of limited flow rate, and follow-up comprising B
Public, the ACL table that utilizes on it storage with the public network flow restriction of fictitious host computer at B
PublicNumerical value, be equivalent to IP thus
PublicWith B
PublicBind together.
At this moment, fictitious host computer can be with B
PublicAnd B
PrivateThe speed of smaller value visit external network among both.
Preferably, consider in actual applications that ordinary priority guarantees external network traffic speed, in embodiments of the present invention, because the bandwidth device all can be known for public-network bandwidth and the private network bandwidth of virtual unit inside and outside the management and control, therefore can also comprise the steps:
The inside and outside bandwidth device of management and control is the B of fictitious host computer relatively
PublicAnd B
PrivateSize, work as B
PublicGreater than B
PrivateThe time, whether the remaining bandwidth that detects the physical host at fictitious host computer place is not less than B
PublicIf determine that remaining bandwidth is less than B
Public, then to the user feedback error message; If determine that remaining bandwidth is not less than B
Public, then the switch to the fictitious host computer opposite end sends the instruction of adjustment private network flow velocity, comprises IP in the instruction at least
PrivateAnd B
PublicAfter switch is received instruction, according to IP
PrivateNavigate to the network port, again according to the B that comprises in the instruction of private network flow velocity
Public, utilize ACL that the flow velocity of private network bandwidth is adjusted to B
PublicNumerical value.
When the user with public network address IP
PublicWhen being tied to other main frames, further, in the present embodiment, this method also comprises:
The inside and outside bandwidth device control of management and control NAT device configuration address transformation rule, this address translation rule is used for IP
PublicBe converted to the private net address of above-mentioned another fictitious host computer application.
Because in the prior art, namely be to finish public network address to the conversion of private net address by NAT device, therefore only need in the present embodiment when public network address is tied on the new fictitious host computer, the inside and outside bandwidth device of management and control sends instruction notification NAT device configuration address transformation rule and gets final product.And then can realize that public-network bandwidth can move the technique effect that uses between different main frames.

In addition, in the present embodiment, if run into the situation that to revise bandwidth at certain IP address, also provide following scheme: need to prove: because this scheme is IP for what revise
PublicBandwidth or IP
PrivateBandwidth all be suitable for, therefore when introducing following proposal, do not do special differentiation.
The inside and outside bandwidth device of management and control receives the request of revising IP address bandwidth, comprises IP address, preceding former bandwidth and amended new bandwidth, i.e. the target bandwidth of modification that needs are revised in this request; The inside and outside bandwidth device of management and control according to this IP address detected its whether in corresponding equipment (if former IP address is IP
Public, this corresponding equipment is NAT device; If former IP address is IP
Private, this corresponding equipment is switch) on the bandwidth of existing binding whether; If no, then directly former bandwidth is revised as new bandwidth; If have, check then whether the remaining bandwidth on the corresponding device is not less than new bandwidth, if remaining bandwidth is enough, then the former bandwidth (associated bandwidth) with this IP address binding is revised as new bandwidth, if remaining bandwidth less than new bandwidth, is then revised failure, return the response of revising failure and give the user.
Further, present embodiment discharges under the situation of IP address at needs, following scheme is provided: the inside and outside bandwidth device of management and control receives the request that discharges the IP address, comprises the IP address of needs release in this request. and the bandwidth device checks that whether this IP address has the bandwidth of binding at NAT device or switch inside and outside the management and control; If no, then directly delete this IP address, if the bandwidth of binding is arranged, then return the response of release failure and give this user.
The embodiment of the invention can be carried out speed limit respectively to public network and VPN traffics according to the type of IP address, therefore can be free for user's virtual machine or the private network bandwidth of at a low price open q.s, and to public-network bandwidth, then can limit as required or charge, can satisfy public-network bandwidth simultaneously and between different main frames, move the requirement of using.
