Handshake package: the simplest package, in the following format: Sync + PID (note that each package has a different type, USB defines ten packages, for details, see question 5) (3) Transactions: There are three major transactions: in transactions, out transactions, and setup transactions, each transaction is composed of three

Principle 1: major projects are divided into several milestone important stages. There is a buffer time between stages, but there is no separate product maintenance. Microsoft usually adopts the "synchronization-stable product development method ". The life cycle of a typical project consists of three phases: the planning phase: the description of the completion function and the final formulation of the schedule. Development Phase: Write complete sour

Standby, sleep (suspend-to-Ram), and hibernation (suspend-to-disk) use different stages. Before entering the next stage, you must call the callback function of this stage for each device. Not all bus and device classes support all these callbacks, and not all drivers use these cal

4.3.2 Working Principle of pppoe ProtocolThe pppoe protocol workflow consists of two phases: discovery and session. The discovery phase is stateless to obtain the Ethernet MAC address of the pppoe end (on the local ADSL device, and create a unique pppoesession_id. After the discovery stage ends, it enters the standard PPP session stage. When a host wants to start a pppoe session, it must first perform the discovery phase to identify the local Ethernet

is the so-called PPP frame header compression. 2. Four phases of PPP session Since we need to explain the PPP protocol in detail, we must understand the four stages of the PPP protocol. A complete PPP session consists of four phases: the link establishment phase, the link quality phase, the Network Layer Control Protocol phase, and the link termination phase 2 ). (1) link establishment phase: both parties

models (evolutionary model)Primarily for software development that does not have a complete definition of requirements in advance. Users can give the core requirements of the system to be developed, and when the core requirements are realized, they can effectively provide feedback to support the final design and implementation of the system. Software developers based on the needs of users, the first development of core systems. When the core system is put into operation, the user tries to finis

larger perspective (i.e., continuous delivery), not just from the automated deployment process (although this is important). First, let's look at the typical process from code to final service in software production (e.g.).As you can see, writing code from developers to service end users is a lengthy process that can be divided into three phases:1. From code to Product library (ARTIFACT): This phase of the development of the developer's code to conti

, packet encapsulation at the IPSec virtual tunnel interface eliminates the need for additional encapsulation of GRE headers or L2T for incoming tunnel traffic compared to IPSec over GRE or IPSec over L2TP tunnel encapsulation The P-header reduces the level of packet encapsulation and saves bandwidth.More flexibility in business applications: IPSec virtual Tunnel interface in the implementation of the clear areas of the "pre-encryption" and "post-encryption" two

Analysis of early and second phases As mentioned above, you may not be so unfamiliar with the relationship. The following is a detailed analysis. The following figure shows the images of the hexagrams:9th: Do not use Qianlong My friends who have read the previous a

1. The bandwidth is 4 kHz., If 8 differentThe physical status indicates data, and the signal-to-noise ratio is 30db. therefore, the maximum data transmission rate is calculated based on the neeness criterion and Shannon theorem. ① c = 2 F log2n = 2*4 K * log28 = 24 kbps ② dB calculation is: 10lgs/N, that is, this article entitled: 10lgs/n = 30 then: s/N = 103c = f log2 (1 + s/n) = 4 K * log21001 = 40 kbps 2. For a 6 MHz channel, if four different States are used to represent data, what is the ma

setting. For example, you may build a library and an application linked to the library (the same workspace ). Xcode can discover this relationship and automatically build this library first. However, if you want to link a version of the library instead of one built in the workspace, you can create a definite dependency in build settings, which will overwrite implicit dependency.

Set up an IPSec VPN for Strongswan in CentOS 6.3 I. Software Description IPsec is a type of Virtual Private Network (VPN) used to establish an encrypted tunnel between the server and the client and transmit sensitive data. It consists of two phases: the first phase (Phrase 1, ph1), the exchange key to establish a connection, the use of Internet Key Exchange (ike) protocol; the second phase (Phrase 2, ph2 ), after the connection is established, data is

Structure Description Figure 4. EMPs Structure Description The brain chart is relatively simple. For details, refer to brain Chart "extended attributes Scheme". Here is a brief description: LStatic Structure In general, the static structure is relatively simple and mainly divided into two layers. The underlying layer is the abstract attribute metadata provision subsystem, while the other layer is the EMPs core built on the former: extended attribute subsystem during runtime. Ab

(specifically, two-phase commit mainly guarantees the atomicity of distributed transactions: that is, all nodes are either completely or completely ). The so-called two phases refer to the preparation and submission phases. Figure 2.

This function must accept the event object as its unique parameter and cannot return any results, as shown in the following example: access modifier fu
