sent from the client to the server cannot be greater than this value.
In actual transmission, both parties usually take the minimum value of the two as the maximum package size sent by both parties.
Based on the above communication process, we will analyze the above two packet capture content:
Packet Capture 1:
The client sends a SYN packet, indicating that the maximum acceptable MSS value is 1460. The Server Load balancer device responds with an acceptable MSS value of

For a complete IPv6 address, need to write 128 bits, has been divided into 8 paragraphs, 4 characters each, that is, the complete representation of a IPV6 address, need to write 32 letters, which is quite long, and easy to confuse and error, so IPv6 in the representation of the address, is fastidious, so far, IPV6 addresses are represented in three ways, namely:1. Preferred format2. Compression representation3.ipv4 embedded in the IPV6The following are details of these three IPv6 address represe
As one of the world's most famous PC manufacturers, Dell released VostroV13 ultra-thin business laptop, which is Dell's first ultra-low price notebook dedicated to enterprise users. The starting price of the Low-configuration version is USD 449 (about RMB 3000). It uses the Intel saiyang 743ULV processor and pre-installs the UbuntuLinux operating system; the standard version starts with $649 (about $4400) and uses Intel Core2DuoSU7300, SU3500 processor, pre-installed Window

Microsoft launched its own Windows 8 x86 tablet SurfacePro, which will sooner or later steal the business of other PC manufacturers. Many hardware manufacturers have begun to plot countermeasures. Dell's countermeasure is to embrace Linux. Dell has just launched Ubuntu XPS13, pre-loaded Ubuntu12.04PrecisePangolin, for $1,449, $50 cheaper than Windows. XPS is mainly intended for the consumer market, but recently DellUSA once again announced

system is measured; recall is the ratio of the number of related documents retrieved and the number of related documents in the document library, which is measured by the recall of the retrieval system.
In general, precision is the number of items retrieved (such as documents, Web pages, etc.) that are accurate, and recall is how much of the exact entries have been retrieved.
The correct rate, recall rate and F value are the important evaluation indexes of the target in the mixed environ
The accuracy rate, recall rate, and F value are important evaluation indicators of the target in a mixed environment. In this paper, these three indicators are favored.
Let's take a look at the definition of these indicators first:
Accuracy Rate = Total number of correctly recognized individuals/total number of identified individuals
Recall rate = Total number of correctly recognized individuals/total number of individuals in the test set
F value = accuracy * recall rate * 2/(accuracy rate +
In the database, a null value is used to indicate that the actual value is unknown or meaningless. In a table, if a column in a row has no value, it is called NULL ). A null value can be returned for any data type column as long as the non-NULL or primary key integrity restriction is NOT used. In practical applications, ignoring the existence of null values may cause unnecessary troubles.
For example, in the following employee table (EMP), the employee name (ENAME) is KING's Row, because KING i

Example: There are 1400 carp, 300 shrimp and 300 turtles in a pond. Now for the purpose of catching carp. Sprinkle a big net, caught 700 carp, 200 shrimp, 100 turtle. So, these indicators are as follows:
Accuracy = 700/(700 + 200 + 100) = 70%
Recall rate = 700/1400 = 50%
F value = 70% *
correct message bar/sample extracted
The value is between 0 and 1, the closer the value is to 1, the higher the precision or recall.
3. F = Correct rate * Recall rate * 2/(correct rate + recall rate) (f value is the correct rate and recall rate of the harmonic mean)
Take this example: there are 1400 carp, 300 shrimp and 300 turtles in a pond. It is now for the purpose of catching carp. 700 Carp, 200 shrimp and 100 turtles were caught in a large net.
(such as documents, Web pages, etc.) is accurate, recall is the number of all accurate entries have been retrieved.
The correct rate, recall rate and F value are the important evaluation indexes to select the target in the mixed environment. Take a look at the definition of these indicators first:
Correct rate = number of correct message strips/extracted information strips
Recall rate = Number of information in the correct Information Bar/sample extracted
The value is between 0 and 1, the close
The correct rate, recall rate and F value are the important evaluation indexes of the target in the mixed environment.Consider the definition of these indicators first:Correct rate = number of individuals correctly identified/number of individuals identifiedRecall rate = Number of individuals correctly identified/total number of individuals present in the test setF value = correct rate * Recall rate * 2/(correct rate + recall rate)Example: There are 1400
:
1. Correct rate = The correct number of messages extracted/the number of extracted information bars
2. Recall rate = The correct number of information to be extracted/the number of information bars in the sample
The two values are between 0 and 1, the closer the value is to 1, the higher the precision or recall.
3. F value = correct rate * Recall rate * 2/(correct rate + recall rate) (f value is the harmonic mean of correct rate and recall rate)
