When business number of requests exceedes the reasonable quantity of service RRN in the unit interval, the quantity of service limits the initiated access of module 138 and limits
Function, within service request quantity to be limited to the reasonable quantity of service RRN in the unit interval.Specifically, when in UPnP network
When the service request quantity at the UPnP control points of access in radio exceedes reasonable quantity of service RRN1 in the unit interval, by input and output
The service request quantity of interface is limited to the UPnP numbers of control points of the RRN1 × input/output interface connection；When in UPnP network
When the service request quantity at the UPnP control points of wireless access exceedes reasonable quantity of service RRN2 in the unit interval, according to MAC ground
Location obtains the position at UPnP control points, and the service request quantity at the UPnP control points of the wireless access is limited to into the unit interval
Within interior reasonable service request amount R RN2.
Fig. 3 is seen also, Fig. 3 is the flow chart of the better embodiment of service request control method one of the present invention.
Step S301, the number of control points that the detecting of number of control points detecting module 132 is coupled with router 100.Specifically
Ground, when UPnP control points are connected by wired mode with router 100, by inquiring about DynamicHost agreement is arranged（Dynamic
Host Configuration Protocol, DHCP）In lease list obtain current IP address discharging quantity, wherein often
One IP address correspondence, one UPnP control points.In other embodiments, can be by inquiring about bridge（Bridge）In address list
Obtain the access quantity at the UPnP control points of access in radio to the router 100 in UPnP network.
When UPnP control points are wirelessly connected with router 100, the UPnP control points of wireless access are both needed to lead to
Crossing certain authentication mechanism could connect router 100, so as to router 100 can obtain the basic letter of wireless access control point
Breath such as MAC Address.The router 100 can be according to wireless access in the acquisition of information UPnP network such as MAC Address or IP address extremely
The access quantity at the UPnP control points of the router 100.
The UPnP network access control point total amount is the access quantity and wireless access at the UPnP control points of access in radio
The access quantity sum at UPnP control points.
Step S302, the quantity of service computing module 134 is according to number of control points and service request response Time Calculation list
The reasonable service request quantity at control point in the time of position.Specifically, the reasonable quantity of service in the unit interval（Reasonable
Request Number/second, RRN）=access control point total amount（Total Number of control points,
TNCP）× 1 second/ most slow-response times（Most slow Response time, ms）× ambient parameter（Environment
Value, EV）.The quantity of service computing module 134 calculates respectively access in radio control point and wireless access control in UPnP network
Reasonable quantity of service RRN1 and RRN2 in the unit interval of system point, and RRN=RRN1+RRN2.Ambient parameter EV receives Netowrk tape
Width, routing capabilities of router etc. affect.Wherein ambient parameter can be turned down in the environment of rarely needed UPnP services.
Step S303, the control point service request quantity in the detecting unit interval of quantity of service detecting module 136 and service
Request source.Specifically, the quantity of service detecting module 136 detects the service at access in radio UPnP control points in the UPnP network
Number of requests and the service request quantity at wireless access UPnP control points, and obtain the clothes in the unit interval of all UPnP control points
Business number of requests.The quantity of service detecting module 136 also distinguishes access in radio UPnP by the IP address of query service request
The service request at control point and the service request at the UPnP control points of wireless access.
Step S304, judges whether the service request quantity in the unit interval exceedes the reasonable service number in the unit interval
Amount.Specifically, whether the service request quantity at access in radio UPnP control points in the unit interval is judged more than RRN1, and during unit
Whether the service request quantity at interior wireless access UPnP control points is more than RRN2.When access in radio UPnP controls in the unit interval
When the service request quantity at point or wireless access UPnP control points exceedes the reasonable quantity of service in the unit interval, execution step
S305.When within reasonable quantity of service of the service request quantity in the unit interval within the unit interval, execution step S303.
Step S305, the quantity of service limits the initiated access limitation function of module 138, and service request quantity is limited to into list
Within reasonable quantity of service RRN in the time of position.Specifically, when the service at the UPnP control points of access in radio in UPnP network please
When asking quantity to exceed reasonable quantity of service RRN1 in the unit interval, the service request quantity of input/output interface is limited to into RRN1
The UPnP numbers of control points of × input/output interface connection；When the service at the UPnP control points of wireless access in UPnP network please
When asking quantity to exceed reasonable quantity of service RRN2 in the unit interval, the position at UPnP control points is obtained according to MAC Address, and should
The service request quantity at the UPnP control points of wireless access is limited in the unit interval within reasonable service request amount R RN2.
Using above-mentioned service request control system and its control method can according to number of control points and service response when
Between reasonable service request quantity in the unit of account time, and control point service request quantity is limited to into reasonable service request quantity
It is interior, so as to plug and play network can be avoided to be subjected to the paralysis sexual assault of Connection Service request.
Above example is only unrestricted to illustrate technical scheme, although with reference to preferably implementing to the present invention
Be described in detail, it will be understood by those within the art that, technical scheme can be modified or
Equivalent, without deviating from the spirit and scope of technical solution of the present invention.
