For setting terminal IP sets up the tc filter, the device that the packet of mark is filtered.
The present invention utilizes the tc among the iproute2 that rule is set in the router of local area network (LAN), guarantees that setting terminal IP exclusively enjoys the part bandwidth, has overcome when competing shared bandwidth by free terminals all in the local area network (LAN) at present, can not satisfy the deficiency of crucial terminal needs.
Below through combining specific embodiment and accompanying drawing that the present invention is further explained.
Description of drawings
Accompanying drawing 1 is the embodiment of the invention 1 flow chart.
Embodiment
As shown in Figure 1, present embodiment is provided with rule through the tc among the iproute2, and kernel is guaranteed for the terminal IP (trust ip) that sets provides the predetermined network bandwidth according to the rule of appointment.
According to the percentage that takies of bandwidth total value that is provided with and trust ip, the minimum bandwidth that trust ip is set takies percentage for the bandwidth total value multiply by, and maximum bandwidth is a WAN mouth physics maximum rate; The maximum value bandwidth that non-trust ip is set is the minimum bandwidth that actual total bandwidth deducts trust ip, and minimum bandwidth is 60Kbps.The speed that can guarantee trust ip like this can reach the physics maximum rate, and being unlikely to other IP has not again had flow.Flow chart is as shown in Figure 1:
1. obtain actual bandwidth (being assumed to be CKbps), trust ip (being assumed to be 192.168.1.99), reserved bandwidth (be assumed to be A Kbps, A < C)
2. set up root qdisc formation
tc?qdisc?add?dev?br0?root?handle?1:?htb?default?21
3. set up classification
1) root classification, it is 100Mbit that minimum-rate is set, maximum rate is 100Mbit:
tc?class?add?dev?br0?parent?1:?classid?1:1?htb?rate?102400Kbit?ceil?102400Kbit
2) Trust ip subclassification, it is user defined value A that minimum-rate is set, and maximum rate is 100Mbit, and priority is for the highest: tc class add dev br0 parent 1:1 classid 1:11 htb rate A ceil 102400Kbit prio 0
3) non-trust ip subclassification, it is 600Kbit that minimum-rate is set, and maximum rate is (C-A), and priority is low slightly: tc class add dev br0 parent 1:1 classid 1:21 htb rate 600Kbit ceil (C-A) prio 1
4. set up the sfq formation of trust ip subclassification.

Implementation effect
(total bandwidth is that 12Mbps, trust ip keep 6Mbps, uses same downloaded resources)
1. open and quicken before the function
| The PC numbering | 1 | 2 | 3 | 4 |
| The IP address | 192.168.1.2 | 192.168.1.4 | 192.168.1.3 | 192.168.1.5 |
| Trust ip | Not | Be | Not | Not |
| Speed | 4Mbps | 2Mbps | 3Mbps | 2Mbps |
From on can find out before open not quickening function do not have tangible strengths and weaknesses between 4 computers below the router, just belong to the free competition state.
2. open and quicken after the function
| The PC numbering | 1 | 2 | 3 | 4 |
| The IP address | 192.168.1.2 | 192.168.1.4 | 192.168.1.3 | 192.168.1.5 |
| Trust ip | Not | Be | Not | Not |
| Speed | 1Mbps | 8Mbps | 1.2Mbps | 0.3Mbps |
Open to after the acceleration function of specific IP, the speed of trust ip obviously improves.
