I. CAR overview CAR is the most widely used method in the Cisco environment. It marks data packets at the network edge Entry and Exit. CAR can implement one of the two functions. Function 1: speed limit; function 2: sets classified data packets by using IP priority and QOS groups; 2. Syntax: rate-limit {input | output} [access-group [ra

Most users believe that the high-speed download of the Thunderbolt will occupy too high a CPU occupancy rate, which is completely committed to the empirical error. In fact, the thunderbolt can be achieved high-speed, efficient and exist, the overall reduction of CPU occupancy rate.
First, traces of the Thunder Why can reduce CPU occupancy rate
1. Deep understan
Today, in training the network to change a learning strategy to try, so re-study the various learning strategies offered in the Caffe, here and you talk about my use of some of the lessons.
Let's take a look at the parameters related to the learning rate strategy, and the following are from Caffe.proto:
The learning rate decay policy.
The currently implemented learning
Oracle DatabaseIt can be said that the database industry occupies a very important position and leads the development of the database. This article is about Oracle Database debugging andOptimizationThis article mainly introduces Oracle DatabaseHit rateRelated issues, including performance comparison between different algorithms.
Computing of various hit rates in Oracle and related Tuning
1) hit rate of Library Cache:
Calculation formula: Library Cache
such as the Cisco 2960x-24ps-l (24,000 Gigabit Port 4,000 gigabit), forwarding bandwidth 108Gbps, switching bandwidth 216Gbps, packet forwarding rate 71.4Mpps, according to the non-clogging line speed forwarding to calculate, exchange capacity of 2*28*1gbps=56gbps, The nominal 216Gbps is much higher than this, why? Is it due to the different design of the switch matrix? How did he figure out the 216Gbps? Again, for example: its packet forwarding
True positive (true, TP) is predicted as positive samples by the model;
True negative (true negative, TN) is a negative sample predicted as negative by the model;
False Positive (false positive, FP) is predicted as positive negative samples by the model;
False Negative (false negative, FN) positive samples predicted as negative by the model;
True positive rate (true rate, TPR) or sensitivity)TPR = TP/(TP +
The baud rate of usart set in the stm32 library is multiplication and division, and the initialization code can be used directly, but the code efficiency should be improved,Enter the immediate Number of fractional division values to the BRR register and change the baud rate.
So I wrote the following macros. I hope they will be useful.
/* Macro of the fractional division value of the baud
Bounce rate is an important concept, it mainly reflects the popularity of the page, and whether or not to solve the problem of users, high bounce rate is not a good phenomenon, the general representative of your site, not too in line with the needs of users, when the search user came in, did not go down to try to browse, and directly close your Web page, High search bounce

The rate of the article is very important to the success of a website, take the author I engaged in the medical industry, the medical industry because the core keywords are basically the large medical portal occupied, such as our hospital website. Only from the long tail of the number of keywords to win, so if there is no good rate of inclusion, the site is basically obsolete. I would like to tell you the 5
Measurement of a website user experience is the most important criterion is the site bounce rate, high bounce rate for a lot of reasons, such as users can not find valuable reference content, server instability, page loading speed too slow, web file is too large and so on, if these problems can not be resolved in a timely manner, the user experience even for the entire site optimization is very unfavorable,
Hello everyone, I am the Phantom of the Rain. For the optimization of the site, back and forth has been more than ten, for the optimization of the site really more or less have some experience, experience is not hidden in the heart of the secret, experience is to be taken out to share. For the optimization of the site sometimes we really can not simply use the keyword ranking to illustrate the problem, these are not the key, because sometimes keyword ranking is good, and does not necessarily hav
The so-called CAR refers to the guaranteed access rate. the inbound and outbound traffic rates of a port or sub-port are classified according to a certain standard ceiling and different QoS priorities are defined, it can only work on IP packets and does not work on non-IP traffic.
1. to control traffic, we need to first identify data packets and then control the traffic. We need to control the data packet type, the bandwidth usage of the throttling us
The website traffic adhesion rate is becoming an important data to measure the quality of website.
Domestic Internet Development 10, I do not know when to assess the quality of a website has been a Third-party statistical platform for a number of figures and graphs of the decision, a number of webmaster every day for that several numbers and rushing to work. Although with the development of this field, more and more people no longer use Alexa data as
