Cheng Tu, network management computer 1 software detects the on off operating mode of communication link in real time, when, after certain link down, writing down current
Time, when communication link is normal, it is judged that the time of interrupted communication link, if the link down time was more than 1 hour, the most standby
Part bandwidth is available free, then the carrier bandwidths interrupting data link is adjusted to protection bandwidth, after protection bandwidth uses 1 hour,
Be adjusted to normal bandwidth, discharge protection bandwidth, leave for other channels broken down use, when two sections of protection bandwidths all
After taking, prompting has not had available bandwidth, when carrier wave adjusts, first adjusts the departure carrier wave of remote station, then adjusts entering of central station
Border carrier wave.
4. NMS uses the mode of detection communication link quality of reception parameter, and automatic decision is the need of to logical
Transmission communication earth station in letter link is transmitted level and adjusts, and adjusts when needing the transmission level to sending communication earth station
Time, automatically control transmission communication earth station level and adjust, and communication link quality of reception parameter after adjusting is compared, according to
Comparison result selects to adjust stepping, is automatically adjusted sending communication earth station transmission level.4. the embodiment present invention walks
In Zhou, webmaster computer 1 is timed monitoring to the Eb/No's of communication link, when detecting that Eb/No value is beyond communication link just
Often during working range, start the transmission level adjustment order sending communication earth station, after adjustment, continue monitoring communication link Eb/
No, when Eb/No value falls in communication link normal range of operation, the transmission level stopping sending communication earth station adjusts.
5. NMS uses automatic regular polling mode, detects communication link on off operating mode, in communication link occurs
Time disconnected, switched by satellite channel, two kinds of routing states of landline phone net and the timing of communication link on off operating mode detects, to master
Standby link automatically switches.In the embodiment present invention 5. step, active/standby link switchover functional realiey remote station defends logical link
And the handoff functionality between dial-up link, complete with unattended station monitoring computer 2 and webmaster computer 1, with reference to figure
3, Fig. 3 is main/slave link automatic switching program workflow diagram of the present invention.Remote station adds when electrically activating, and monitoring computer 2 of standing opens
Dynamic link switching demons, the communication link of timing detection our station and central station is the most normal, if link communication interrupts super
Spend 1 minute, then by the route handoff of this station router to dial-up link, wait and stay in dialing status.Webmaster computer 1 detect each far
The communication link of end station, when finding certain remote station link down more than 2 minutes, detects current dial-up link the most idle,
If available free link, then by the corresponding remote station route handoff of central station router to dial-up link.When defending logical link-recovery
Time, user can select to switch back into from dial-up link to defend logical link, remote station dial-up routing corresponding for central station router is deleted
Remove, disconnect dial-up link and connect.
6. NMS uses to the monitoring downloaded of satellite communication earth station, updates monitoring software, controls
The mode that monitoring software runs, is updated satellite communication earth station monitoring software, runs and safeguards.The embodiment present invention
