These concise tutorials allow you to gain valuable hands-on experience, which you can then use as a basis for your implementation.Second, the introduction 1.

approach is divided into two different situations:(1) Asynchronous duplex: Receive and send in the same program, two different sub processes are responsible for sending and receiving(2) Asynchronous Simplex: receiving and sending is done with two different programs.2, synchronizationMessage sending and receiving is synchronous, both message sending and waiting for receiving return message. The synchronization method generally needs to consider the ti

bandwidth alone, so they do not need to compete with other devices. When node A sends data to node D, Node B can send data to node C at the same time, and both transmission enjoy all the bandwidth of the network and all have their own virtual connections. If a 10 Mbps Ethernet switch is used here, the total traffic of the switch is 2*10 Mbps = 20 Mbps. When a 10 Mbps shared HUB is used, the total traffic of a HUB does not exceed 10 Mbps. In short, a vswitch is a network device that can encapsul

to simply hosting workflows, we can also use the WCF duplex channel to return events from the workflow to the client as the user. This is very beneficial in terms of the "expenditure report" because the solution relies on clients to perform service round-robin to implement regular data updates. However, these clients can also receive notifications directly from the service department. To do this, we must: Define a callback convention. Bi

conflict is identified as a frame verification sequence (FCS) error in the primary network segment. possible causes of this error include:1. nonstandard use of cables, such as exceeding the maximum transmission distance or using an incorrect cable type.2. Abnormal NIC (physical damage or driverProgram).3. incorrect port duplex mode configuration, such as Duplex mismatch. The following are the reasons why

First of all, we need to understand how the map is refresh and how to call back the map. Before proceeding, we will introduce an interface in. net Framwork. System. Web. UI. ICallbackEventHandler, which is an interface for implementing page refreshing in. net, and ArcServer does not need to be refreshed by this interface.Th

The message exchange pattern (Messages Exchange PATTERN:MEP) is an important concept in SOA. The MEP defines a template for the participants to exchange messages, which is a very abstract definition. Actually, we can understand that. MEP: The Message exchange pattern (MEP) represents a series of templates that define the order in which messages are transmitted to each other by the sender and receiver of the message. Message exchange modes include: Datagram Mode (DATAGRAM), request/reply mode (re

In Linux, if you run the ifconfig XYZ command, you will get a lot of information, but there is no such information as the speed and duplex status of the XYZ network interface. Is this reasonable? If you are familiar with windows, you will feel that the output of this command is indeed missing, but can windows ipconfig get this information? No. The speed duplex information of the Windows Nic is displayed aft

node count and half-duplex and full-duplex communication2.1 Node pointsThe so-called number of nodes, that is, each RS-485 interface chip driver can drive the number of standard RS-485 load. According to the regulation, the standard RS-485 interface input impedance is ≥12kω, the corresponding standard drive node number is 32. To accommodate more nodes, the input impedance of some chips is designed to be 1/

twisted pair wires (two signal lines), and the voltage difference between the two lines is used to represent digital signals. For example, if one of the twisted wires is labeled a (positive) and the other is labeled B (negative), when a is a positive voltage (usually + 5 V ), when B is a negative voltage (usually 0), it indicates the signal "1"; otherwise, A is a negative voltage, and B is a positive voltage, it indicates the signal "0 ". RS485/422 allows a communication distance of 1200 meters

First, in the Word2007 quickly realize double-sided printing Word is currently the most common Office software, in Word2007 to achieve double-sided printing is very simple. Click the Office Button, click Select Print in the Drop-down menu, click the Manual Duplex option in the Print dialog box (Figure 1), and then click the Print button to print. Word will first put 1, 3, 5 ... The contents of a single page are sent to the printer for printing, after

connections are often used for frequent operation, point-to-point communication, and the number of connections cannot be too much.Each TCP connection requires a three-step handshake, which takes time, and if each operation is connected first, then the processing speed is much lower.So after each operation is kept open, the next time processing directly send packets on the OK, do not have to establish a TCP connection. For example, a database is connected with a long connection,If frequent commu

Ethernet traffic control technology The data link layer is divided into Logical Link Control Sub-layer, MAC control sub-layer, and Media Access Control (MAC) Sub-layer. The MAC control sub-layer is an optional sub-layer, which specifies a universal full-duplex traffic control structure framework. The carrier listens for Multi-Channel Access/conflict detection (CSMA/CD) the algorithm implements half-

a service for WCF and made a small demo to demonstrate the creation of WCF, which was developed using attribute annotations and is fairly straightforward to define.Next we have a detailed discussion of the message pattern. WCF provides three message patterns, one-way mode, request/answer mode, and duplex mode, and three modes that support client-side sending of messages to the server. The difference is that one-way mode only supports message delivery

of host C. SWA when a reply data frame is received, the map of the source MAC address and interface of the frame is added to the MAC address table. If this mapping relationship already exists in the MAC address table, it will be refreshed. The SWA then queries the MAC Address table and forwards this data frame from G0/0/1 after locating the corresponding forwarding port based on the destination MAC address of the frame.The early Ethernet mode of operation was 10M half-

hundreds of millions of clients to web sites with short connections saves some resources. If persistent connections are used and there are thousands of users at the same time, if every user occupies a connection, you can imagine it. Therefore, a large amount of concurrency is required, but each user needs to be connected in a short connection without frequent operations. In short, the choice of persistent connection and short connection depends on the situation. Sending and receiving Method
