However, the above-mentioned conventional network bandwidth detection method cannot calculate the bandwidth because a specific endpoint fails. Or, because of the network condition between the source endpoint and the specific endpoint, the estimated bandwidth value is greatly changed and cannot be correctly allocated to the actual bandwidth. For example, when the network is congested, it is possible to estimate a lower bandwidth (only 1 Mbps is estimated for 2 Mbps bandwidth). Then the q〇s mechanism uses this lower bandwidth (1 Mbps) for bandwidth allocation and The limitation will cause the user to use only 1 Mbps bandwidth, which will result in waste of bandwidth usage. Conversely, if a higher bandwidth value is estimated (2 Mbps bandwidth is estimated to be 3 Mbps bandwidth), when QoS performs bandwidth allocation and limitation, it is assumed that a high priority allocation is given to 2 Mbps, and a low priority is given to allocate 1 Mbps. A priority of 1Mbps in the traffic bandwidth of 2Mbps will be occupied by low priority, which will make 200939696 high priority. At full load transmission, the maximum σ can only be 1Mbps. Such a situation will result in the fact that only the actual bandwidth of the actual boat is not allocated according to the original set ratio. [Summary of the Invention]

To this end, the present invention provides a network bandwidth detection side of the network device, the main steps include: initializing a predetermined bandwidth value, and loading the predetermined bandwidth value into a bandwidth upper limit value; An automatic detection process ^step ς 6 200939696 The packet stream collects a packet flow every time; the collected frequency of the transmission 疋 time 'to calculate the transmission bandwidth value; wider than the wide value The value between the value and the preset bandwidth value is calculated to estimate the frequency [Embodiment] Ο Ο Method 1 is a flow of the network bandwidth price measurement method of the network device of the present invention.

Bandwidth allocation and limiting features. Step = None of the network bandwidth method described in the present invention, which is mainly prepared for -7 First, when the network device starts to operate, the network setting - detecting frequency rabbit resident program will initialize the network device Show the default bandwidth (DBW), such as step 1 π limit (u and the preset bandwidth value will be loaded on the bandwidth of the network device shown. _Γ Limit Bandwidth; ULBW), Step 112 'and then' enters an automatic detection process 130. The automatic detection process 130' described at the beginning includes the following steps: Set 2 Under I: Collect a packet flow rate within a rated time', for example, as shown in Fig. 131 every 5 seconds. Prepare all external or internal packet traffic (B), as in step 'Separate the collected packet traffic (8) by the rating (4) to calculate 7 200939696 a Transmission Bandwidth (TBW), as in the following formula ( 1) Calculated: &gt; TBW-(Bx8)/5 (1) By this, 'the transmission bandwidth value (TBW) in bps (bits per second)' will be obtained as shown in step 132. Of course, the above rated time can also be adjusted for the accuracy of network traffic detection. For example, the longer the rated time, the more accurate the transmission bandwidth value (TBW). In addition, the packet flow rate (B) is selected in units of bits in addition to the above selection, and may alternatively be in units of bytes or k-bytes. Continuing, as shown in step 133, comparing the size between the transmission bandwidth value (TBW) and the preset bandwidth value (DBW), if the transmission bandwidth value (TBW) is greater than the preset bandwidth value (DBW), Then proceed to step 134. Conversely, if the transmission bandwidth value (TBW) is less than the preset bandwidth value (DBW), then return to step 131 ’ to continuously collect the packet traffic. Next, as shown in step 134, when the transmission bandwidth value (TBW) is greater than the preset bandwidth value (DBW), the transmission bandwidth value (TBW) is substituted into a bandwidth grading equation (2): EST BW=[(TBW) + 64K) mod 128Κ]χ128Κ (2) will calculate the estimated juice bandwidth value (Estimate Ban (jwidth; EST BW). This bandwidth classification equation (2) is the bandwidth commonly used by today's Internet service providers. Hierarchical mode, and the m〇d function in equation (2) is the division quotient operation in the mathematical formula, and this embodiment uses 128κ as a unit of bandwidth hierarchy classification. In other words, the bandwidth classification equation 8 200939696 (2) After the calculation, it is possible to obtain an estimated bandwidth value (ESTBW) of 〇κ, 128κ, 256Κ, 384K, 512K, 64〇Κ·. (hierarchical way and so on). Of course, in another embodiment of the present invention Different unit values can be used as the classification of the bandwidth level, for example: 32K, 64 or 256 feet, etc., to calculate the estimated bandwidth value (EST BW) of different bandwidth levels for the network bandwidth. 135 shows the estimated bandwidth value (EST BW) calculated by the bandwidth grading equation (2) and the current network. The upper frequency limit (ULBW) recorded in the device is compared by size. If the estimated bandwidth value (Est Bw) is greater than the upper bandwidth limit (ULBW), step 136 is performed. Otherwise, the estimated bandwidth value (ESTBW) If it is less than the upper bandwidth limit (ULBW), return to step U1 ' to continuously collect the packet traffic (B). If 'as shown in step 136', the estimated bandwidth value (EstBW) has exceeded the frequency previously recorded by the network device. The upper limit value (ULBW), the estimated bandwidth value (estbw) will be loaded into the upper bandwidth limit (ULBW) to replace and update the upper bandwidth limit (ULBW) recorded by the network device. 'After the above steps, even if the network device is connected to other network lines with different bandwidths, the users of the network do not know the bandwidth limit of the network line (ULBW)' can still dynamically set the network device. The upper limit bandwidth value (ULBW) is used to facilitate the setting of the network bandwidth allocation and the limitation. Furthermore, the network bandwidth debt measurement method of the present invention can detect the upper limit of the bandwidth when the network is uploaded or when the network is downloaded. The upper bandwidth limit. Therefore, the upper bandwidth limit (ULBW) set in the network device will be selected to include There is one of the Upper Limit Upper Limit Bandwidth (IJULBW), a 200939696 Frequency Down Upper Limit Bandwidth (DULBW), and one of the combinations thereof. The network bandwidth measurement method can perform network bandwidth detection without packet transmission for a specific endpoint. In other words, the detection method can immediately perform network bandwidth detection for the network endpoint to which the network device is connected. As such, the network bandwidth detection method of the present invention will be close to the use of the network and increase the convenience of the network device in the application of the network bandwidth. In addition, the network device of the present invention includes at least one wired network interface (for example, an 802.3 Ethernet interface) and/or at least one wireless network interface (for example, 802.11a, 802.11b/g), so that The network bandwidth measurement method of the invention can be applied to a wired network (Adsl,

In addition, the automatic detection process 130 of the network bandwidth detection method of the present invention has a detection period (for example, 5 seconds, 1 second or i minutes) to detect the loop through the parent detection period. The download bandwidth of an external network (for example, connected to the Internet) running in the road device system or the update of the download bandwidth of the internal network (for example, a regional network), and finally an accurate physical line can be obtained.

Of course, a self-setting process 120 is provided for the user to operate the settings. Moreover, a network device will be included in the network device of the embodiment of this embodiment. As shown in Figure 1, when the network device starts operating, a dynamic detection bandwidth resident program in the network device will initialize the network device - the preset bandwidth value (DBW) as shown in step 111. And the preset bandwidth value (DBW) will be loaded into the network device first bandwidth upper limit (ULBW), as shown in step 112. The resident program will then check to see if the user has entered a set bandwidth (Set Bandwidth; SBW) through the user interface of the network device. If the user does enter the set bandwidth value (SBW) into the network device system, the user enters a self-setting process 120. Otherwise, the automatic browsing process 130 is entered, as in step 121. When the network device enters the self-setting process 120, the set bandwidth value (SBW) input through the user interface will be loaded into the upper bandwidth limit (ULBW), as in step 122, and then proceeds to step 123, where the resident program will Check if the user has updated or modified the bandwidth upper limit (ULBW). If the bandwidth upper limit (ULBW) is indeed updated or modified, it will return to step 121' to check if the user inputs the set bandwidth value (SBW) through the user interface. Otherwise, the operation status is maintained in step 123 without any modification action. Therefore, the network bandwidth detection method of the present embodiment provides a self-setting process 12 and an automatic detection process 130 two bandwidth upper limit values (ULBW) setting mode to increase the user's network. The selectivity of the device's upper bandwidth limit setting. 11 2009 39696 The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the practice of the present invention, that is, the shape, structure, features and spirit of the scope of the patent application of the present invention are The specialization should be included in the patent application of the present invention. =equal change and modification 'all' [Simplified description of the drawings] Fig. 1 is a flow chart of an embodiment of the network for injury of the present invention.
