Port status does not change determination module for a long time, be used to obtain the running status transformation period and equipment current running time last time of described port, determine the state variation the time threshold whether difference of current running time of equipment and port running status last time transformation period is set greater than state variation time threshold setting module, in this way, determine that port status does not change for a long time.
Whether the present invention changes for a long time by Port Management state, port running status, port running status is comprehensively judged, thereby can determine the idle condition of port efficiently and accurately.
Description of drawings
Fig. 1 is the flow chart of the device free port decision method of the specific embodiment of the invention.
Embodiment
Contrast accompanying drawing and the present invention is elaborated below in conjunction with embodiment.
Inventive concept of the present invention mainly is: factors such as whether port controlled state, running status, running status do not change for a long time comprehensively judged, thus judgment device port idle port whether efficiently and accurately.
With the broadband access equipment be below example the present invention will be described, it will be appreciated, of course, that decision method of the present invention is not limited to broadband access equipment, can be applied to other network equipments equally.
As shown in Figure 1, the idle port decision method flow process of the specific embodiment of the invention comprises:
S101, obtain the controlled state of a certain port of equipment.The Port Management state for example obtains by the Port Management interface in the webmaster.
S102, this Port Management state is judged.If the controlled state of this device port is forbidden, then this port of decidable is an idle port, can set up an idle port tabulation to make things convenient for checking of idle port, and after judging that port is idle port, then flow process is carried out step S109; Otherwise,, then carry out next step if the device port controlled state is enabled.
S103, obtain the running status of port.As hereinafter, the port running status can be recorded in the field of NMP equally, only need read corresponding define field, can get access to the port running status.
S104, this port running status is judged.If presence, then this port of decidable is busy port, and flow process is carried out step S110.Otherwise port is an off-line state, then carries out next step.
S105, the equipment that obtains current running time, equipment current running time can be by SNMP (Simple Network Management Protocol, Simple Network Management Protocol) definition of the field sysUpTime in the agreement is also therefrom obtained, and refers to that the equipment self-starting is to come the current time.
S106, obtaining running status transformation period last time of port, also is the final online time of port, can and therefrom obtain by the ifLastChange Field Definition of interface management information table in the snmp protocol.
The execution sequence that is appreciated that step S105 and S106 can exchange mutually.
S107, port running status last time transformation period and equipment are compared current running time, deduct port running status last time transformation period, the difference of current running time of the equipment that obtains and port running status last time transformation period current running time with equipment.
S108, the state variation time threshold is set in equipment, this threshold value can be determined by a large amount of experiments, whether the difference of current running time of judgment device and port running status last time transformation period is greater than this state variation time threshold, if greater than, judge that then this port is an idle port, carry out next step, otherwise carry out step S110.
S109, idle port is joined in the idle port tabulation.
Whether the port on S110, the judgment device has traveled through, if do not have, then turns back to step S101 and repeats above-mentioned steps, to obtain the idle condition of other port on the equipment.Otherwise if port has traveled through, then flow process finishes.
Can write down the port numbers of idle port in the idle port tabulation, and statistics idle port quantity, for checking.Certainly, the scene of also can adopting reports mode, judges that promptly a port is an idle port, then reports the port numbers of this idle port to webmaster, and then the port traversal finishes, and reports idle port quantity to give webmaster.
The present invention also discloses a kind of decision maker of device free port, comprises device port first identifying unit, device port second identifying unit, device port the 3rd identifying unit:
Device port first identifying unit is used to obtain the controlled state of device port, is forbidding as controlled state, determines that then this port is an idle port; Controlled state is transferred to device port second identifying unit and is judged for enabling else if;
Device port second identifying unit is used to obtain the running status of described port, is online as running status, determines that then this port is busy port; Running status is an off-line else if, transfers to device port the 3rd identifying unit and judges;
Device port the 3rd identifying unit is used for determining whether state does not change described port for a long time, in this way, determines that this port is an idle port.
Wherein, device port the 3rd identifying unit comprises:
State variation time threshold setting module is used for set condition transformation period threshold value;
Port status does not change determination module for a long time, be used to obtain the running status transformation period and equipment current running time last time of described port, determine the state variation the time threshold whether difference of current running time of equipment and port running status last time transformation period is set greater than state variation time threshold setting module, in this way, determine that port status does not change for a long time.
Adopt the present invention, can judge idle port efficiently and accurately and count idle port quantity,, thereby can save unnecessary purchase cost therefore for next step the buying of equipment operator provides accurate foundation.Adopt the present invention, whether comprehensive Port Management state, running status, running status not combined factors judgement such as variations for a long time, under the port off-line state, only need the last state update time of current running time of fetch equipment and device port, with regard to this port of decidable idle port whether, whole decision method is simple and easy to do, take resource few, take a short time, can save system resource and development cost.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, but this example of just lifting for ease of understanding should not think that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can make various possible being equal to and change or replacement, these changes or replacement all should belong to protection scope of the present invention.
