This article describes how to use the socket interface to manage the Buffer Queue in a Linux user space and send and receive two threads. The Code includes the following points: 1) Use two threads to manage the sending and receiving queues, and

Non-blocking I/O includes non-blocking input operations, non-blocking output operations, non-blocking receiving foreign connections, non-blocking initiating outgoing connections. The functions included are: Read, Readv, recv, Recvfrom, Recvmsg,

Kernel version: 2.6.34 UDP packet ReceptionThe reception of UDP message can be divided into two parts: the protocol stack receives the UDP message, inserts the corresponding queue; the user calls Recvfrom () or recv () system call to take out the

Recently, someone often mentions how Exchange's multiple domain names are implemented, simply collating a document and communicating with everyone. By default, the default policy for Exchange Server 2010 is to send and receive mail using the same

Abstract: This paper discusses how to use the serial port with FIFO to reduce the number of received interrupts, and gives the frame packing method through a custom communication protocol format, and then introduces a special serial port data

transmission rate, including 8 gbabit Fiber Channel and 10GbE. Introduced the SFP + module version of optical fiber and copper core, Compared with the Xenpak, X2, or XFP version of the module, the SFP + module retains some circuits on the main board, rather than in the module. SFP type SFP transceiver has a variety of different sending and receiving types. You can select an appropriate transceiver

choose excellent performance.Of course, some manufacturers also associate extended distance support with multimode optical fiber 1300 nm transceiver, such as 1000base-lx. As no 1300 nm source conditions are specified in any standard, multiple methods for producing such transmitters may form the activation of various multimode optical fibers.Therefore, these claims must indicate various possibilities for sp

fibre port is connected successfully. Cascade of Switch Fibre ports Similarly, when a backbone switch is connected to a core switch, the transceiver port of the fiber must also be crossed. The connection between the core switch and the backbone switch. Fibre jumper and switch fibre port type Fiber jumpers are divided into single mode fiber and multimode fiber. Switch fibre ports, jumpers must be consistent with the type of fiber used in the integ

depends on the path or mode. The initial path is determined by the transmitter's enabling conditions. Full bandwidth is generally used for laser transmitters over 155 Mb/s. The minimum bandwidth capacity is low because the conditions for enabling these transmitters vary greatly, generally, there is no overflow condition. RML bandwidth also suffers from the same problem. The study of the rml experiment developed concluded that it is only applicable to 62.5 μm optical fibers and is valid only whe

both ends of the fibre jumper are connected to "collect" or "send", the LED on the port is not lit, indicating that the connection failed. The LED is turned green only if the switch fibre port is connected successfully. Cascade of Switch Fibre ports Similarly, when a backbone switch is connected to a core switch, the transceiver port of the fiber must also be crossed. Connectivity of core switches to backbone switches Fibre jumper and switch fibre

this analysis, we found that the difference between Category 5 and Category 6 options is the same as that between 10 Mbps Ethernet, because NIC and switch are identical. Currently, when purchasing any Ethernet NIC, they usually automatically sense 10/100 Mbps. In this analysis, we also considered multimode optical fiber, because it is a feasible Mbps Ethernet medium. Currently, 100 Base-SX (short wave length) and 100 Base-LX (long wavelength) NICs ca
