Abstract
The invention provides a method for detecting network bandwidth of network equipment, the main steps comprising: firstly, initializing the network equipment to produce a prearranged bandwidth value which is carried to a bandwidth upper range value in network equipment for an automatic detection process, then counting the data packet flow transmitted by the network equipment in a rated time to calculate the transmitting bandwidth value and further to obtain an estimated bandwidth value; if the estimated bandwidth value exceeds the bandwidth upper range value recorded previously by the network equipment, the estimated bandwidth value is carried to the bandwidth upper range value to update the bandwidth upper range value recorded previously by the network equipment. Therefore, detection for the network bandwidth can be made dynamically without special port, to increase the convenience of the network equipment applying on the network bandwidth.
Description
Technical field
The present invention does not need specific endpoints can dynamically carry out the network bandwidth and detects relevant for a kind of network bandwidth detection method of the network equipment, to increase the convenience of the network equipment on the network bandwidth is used.
Background technology
The network equipment now, for example: broadband router or wireless network wideband Wireless Router, for network traffics, allocated bandwidth and limitation function employing network bandwidth management (the Quality of Service of equipment itself; QOS) and COS (Type of Service; TOS) mechanism, and utilize the priority technology to carry out the distribution of bandwidth and the setting of restriction for the flow or the flow of specific endpoints of various different agreements.In addition, the allocated bandwidth of these network equipments and limitation function must learn in advance that the higher limit of external bandwidth could do the operation of pro rate bandwidth at various flows.
Yet most users do not have relevant knowledge background for the setting network parameter; Moreover the user also not necessarily knows own present employed network bandwidth higher limit.So known upload bandwidth value of the general network equipment except requiring user's fan-in network ISP (ISP) to be provided also had a bandwidth detection technology in the meeting certainly, with the operation of doing for the network bandwidth to detect.
Known bandwidth detection technology is for the specific endpoints transfer data packets, and performs mathematical calculations to obtain the discreet value of bandwidth by the turnaround time of packet.But, network state in the network equipment and the specific endpoints, path length and end points survival condition all can have influence on the turnaround time of packet, will make the discreet value of bandwidth produce sizable error range, its error also may be greater than more than 20%, and lacks accuracy.Even if specific endpoints is can't the response data bag, and whole detection technique is uploaded bandwidth with complete failure and can't calculate.In addition, the network equipment that has uses a packet turnaround time technology (Round Trip Time) the estimation network bandwidth, for example send packet, and estimate bandwidth with the time difference of receiving the response data bag at specific endpoints (for example: DNS or NTP server).
But above-described known technology network bandwidth detection method all can lose efficacy because of specific endpoints, and can't calculate amount of bandwidth.Perhaps, because come network condition between source endpoint and the specific endpoints,, and can't correctly be assigned to actual bandwidth so that the bandwidth value of estimating produces significantly change.For example: when network congestion, may estimate lower bandwidth (the 2Mbps bandwidth only estimates the 1Mbps bandwidth), then QoS mechanism adopts this lower bandwidth value (1Mbps) to carry out the distribution and the restriction of bandwidth, will cause the user can only use the situation of 1Mbps bandwidth, and then the waste that causes bandwidth to use.Otherwise, if estimate higher bandwidth value (the 2Mbps bandwidth but estimates the 3Mbps bandwidth), when QoS carries out allocated bandwidth with restriction, suppose to give high priority and distribute 2Mbps, and low priority distributes 1Mbps, then have the 1Mbps will be occupied by low priority among the flow bandwidth 2Mbps of high priority, will make that high priority is the highest when fully loaded transmission can only have the 1Mbps flow bandwidth.So, the situation that will cause actual bandwidth not distribute according to original preset proportion.
Summary of the invention

Embodiment
See also Fig. 1, be the flow chart of network bandwidth detection method one preferred embodiment of the network equipment of the present invention.Network bandwidth detection method of the present invention can be applicable to a network equipment, and can detect actual network bandwidth size dynamically, and then the network equipment can carry out the function of allocated bandwidth and restriction smoothly according to detected bandwidth higher limit.
As shown in the figure, network bandwidth detection method of the present invention, its key step comprises as follows: at first, when the network equipment comes into operation, in the network equipment detection of dynamic bandwidth resident program will the initialization network equipment in a preset bandwidth value (Default Bandwidth; DBW), shown in step 111.And preset bandwidth value is written into the network equipment one bandwidth higher limit (Upper Limit Bandwidth; ULBW) in, shown in step 112.Then, enter an automatic testing process 130.
And this data packet flow (B) that will collect is divided by this time rating, to calculate a transmission bandwidth value (Transmission Bandwidth; TBW), such as formula (1) calculating:
TBW＝(B×8)/5 (1)
Whereby, will obtain with bps (bits per second) is the transmission bandwidth value (TBW) of unit, shown in step 132.
Certainly, also can consider and adjust time length above-mentioned time rating, for example: will obtain a transmission bandwidth value (TBW) more accurately long more time rating for the accuracy that network traffics detect.In addition, data packet flow (B) is the unit of measurement except that above-mentioned selection with bit (bits), in addition can select with byte (bytes) or is unit of measurement with k byte (Kbytes).
Continue, shown in step 133, will compare the size of transmission bandwidth value (TBW) and this preset bandwidth value (DBW), if transmission bandwidth value (TBW) greater than preset bandwidth value (DBW), then carry out step 134.Otherwise transmission bandwidth value (TBW) then returns to step 131 less than preset bandwidth value (DBW), continues to collect data packet flow (B).
Then, shown in step 134, when transmission bandwidth value (TBW) greater than preset bandwidth value (DBW), with transmission bandwidth value (TBW) substitution one bandwidth classification equation (2):
E
STBW＝[(TBW+64K)mod?128K]×128K (2)
To calculate an estimated bandwidth value (Estimate Bandwidth; E
STBW).The bandwidth hierarchical approaches that this bandwidth classification equation (2) is used always for current the Internet services supplier, and the mod function in the equation (2) to be division in the mathematics formula get the quotient computing, and present embodiment is with the bandwidth stratum classification of 128K as a unit.In other words, after calculating, bandwidth classification equation (2) can obtain 0K, 128K, 256K, 384K, 512K, 640K ... estimated bandwidth value (the E of (stratum's mode by that analogy)
STBW).Certainly, can different unit amounts in another embodiment of the present invention as the classification of bandwidth stratum, for example: 32K, 64K or 256K etc., to make the estimated bandwidth value (E of different bandwidth stratum for the network bandwidth
STBW).
Again, shown in step 135, the estimated bandwidth value (E that bandwidth classification equation (2) is calculated
STBW) with the present network equipment in the bandwidth higher limit (ULBW) that write down carry out size relatively, as if estimated bandwidth value (E
STBW) greater than bandwidth higher limit (ULBW), then carry out step 136.Otherwise, estimated bandwidth value (E
STBW) less than bandwidth higher limit (ULBW), then return to step 131, continue to collect data packet flow (B).
If, shown in step 136, this moment estimated bandwidth value (E
STBW) the original bandwidth higher limit (ULBW) that writes down of the network equipment, then estimated bandwidth value (E have been surpassed
STBW) will be written in the bandwidth higher limit (ULBW), with the bandwidth higher limit (ULBW) that replaces and more new network device was write down.
Whereby, through above-mentioned steps flow chart, even the network equipment is connected on the network line of other different bandwidths, and the user of network does not know the bandwidth higher limit (ULBW) of network line, the dynamic upper limit bandwidth value (ULBW) of setting network equipment still is to make things convenient for the setting in network bandwidth allocation and the restriction.
Moreover, the bandwidth upper limit when network bandwidth detection method of the present invention can detect the bandwidth upper limit when network is uploaded or network download.Therefore, the bandwidth higher limit (ULBW) that sets in the network equipment will select to include higher limit (the Uplink Upper Limit Bandwidth that a bandwidth is uploaded; UULBW), higher limit (the Downlink Upper Limit Bandwidth of bandwidth download; DULBW) and the combination one of them.
Again, network bandwidth detection method of the present invention does not need to make data packet delivery for a specific endpoints, just can carry out the network bandwidth and detect.In other words, this detection method can be carried out the action that the network bandwidth detects immediately for the network endpoint that the present network equipment connected.So, network bandwidth detection method of the present invention will be close to the situation that network uses, and increase the convenience of the network equipment on the network bandwidth is used.
Again, the network equipment of the present invention includes at least one cable network interface (for example: 802.3 second are socket too) and/or at least one wireless network interface (for example: 802.11a, 802.11b/g), so that network bandwidth detection method of the present invention can be applicable to be detected on a cable network (ADSL, Cable) or a wireless network (Wireless WAN, WIFI, WiMAX), to meet the demand of variety of network systems.
In addition, the automatic testing process 130 of network bandwidth detection method of the present invention has a sense cycle (for example: 5 seconds, 10 seconds or 1 minute), with cycle detection by every sense cycle, the a pair of outer network that dynamically carries out moving in the network equipment system (for example: last download bandwidth line Internet) or a pair of in network (for example: the renewal of last download bandwidth Local Area Network) finally can obtain the bandwidth higher limit of entity circuit accurately.
See also Fig. 2, be the flow chart of another embodiment of network bandwidth detection method of the network equipment of the present invention.Network bandwidth detection method of the present invention remove to be selected with automatic testing process 130 detection of dynamic amount of bandwidth, provides one to set up flow process 120 on their own and allow user's operating and setting voluntarily certainly in addition.And, will include a user interface in the network equipment of present embodiment.
As described in Figure 1, when the network equipment comes into operation, a detection of dynamic bandwidth resident program in the network equipment
A preset bandwidth value (DBW) in will the initialization network equipment is shown in step 111.And preset bandwidth value (DBW) will be loaded in the network equipment one bandwidth higher limit (ULBW), shown in step 112.
Then, resident program will check whether the user sets bandwidth value (Set Bandwidth by the user interface input one of the network equipment; SBW).If the user will set bandwidth value (SBW) really and be input in the network equipment system, will enter one and set up flow process 120 on their own, otherwise, then enter automatic testing process 130, as step 121.
Set up flow process 120 on their own when the network equipment enters, the setting bandwidth value of being imported by the user interface (SBW) will be written in the bandwidth higher limit (ULBW), as step 122.
Then, enter step 123, resident program will check whether the user makes renewal or modification for bandwidth higher limit (ULBW).Upgrade or modification bandwidth higher limit (ULBW) if having really, will return to step 121, check whether the user sets bandwidth value (SBW) by the input of user interface.Otherwise, do not have any modification action and then maintain step 123 inspection state.
Whereby, the network bandwidth detection method of present embodiment will provide a setting means that sets up flow process 120 and automatic 130 two kinds of bandwidth higher limits of testing process (ULBW) on their own, to increase the selectivity of user on the network equipment bandwidth upper limit is set.
