uplink total bandwidth is used. Downlink bandwidth: The maximum download speed limit and minimum download speed are guaranteed by the WAN port, and the total downlink bandwidth is used when the maximum bandwidth is 0. The matching order of the rules is to match the IP address + port first, then match the port, and finally match the IP address. The following is an example of a pattern (for simple description, the unit of bandwidth is Mbps): ID address segment Port segment mode uplink bandwidt

FTTH as the final development goal of the entire telecommunication network access part, has become a relationship between the telecommunications operators in the future network and technology business transformation of important areas, for this reason, China Telecom has started in Shanghai, Guangdong, Hubei, Beijing four planned FTTH pilot, in order to lay a solid foundation for future scale business. As the world's leading FTTH overall solution provider, the

than or equal to 3, we do not directly delete it to 2 Instead of first deleting it to the nearest (3m+2), then if K is exactly divisible by 3, then we go directly to k-1, and if K is divided by 3 + 1, then it becomes k-2. The advantage of this is that 3m+2 repeats can be most efficiently removed by substituting m characters. So let's take a look at the specific steps, first we figure out more than 20 of th

Permanent Generation size Another rule is that the initial and maximum values of the permanent band (-xx:permsizeand the-xx:maxpermsize) should be permanent with the active object size1.2to the1.5times. In the aboveFULLGCafter that, the permanent occupancy space is2M. Therefore, the recommended size for a permanent generation is2.4Mto the3M,that can be set to-xx:permsize=3m-xx:maxpermsize=3m (1.5Times). 2.

Use the early prototypes, try them out in a similar situation, and discover some of the major design problems early on, so that you don't find the problem until after it's done. Finally, the author gave an interesting example, if you were in a laboratory with a lot of electronic equipment, suddenly found in the clothes pocket 2 The candy melts, what will you do with it?
