1. Packet forwarding rate of the switch The packet forwarding rate of the switch marks the size of the switch forwarding packet capability. Unit General bit BPS (packet per second), the packet forwarding rate for general switches ranged from dozens of kpps to hundreds of MPPs. Packet forwarding rate is the number of packets (MPPs) that the switch can forward per second, that is, how many packets the switch can forward at the same time. Packet forwarding rate reflects the exchange capability of

Before giving you a detailed introduction to the optical fiber access technology, let us first understand the features of China's FTTH target market, and then fully introduce the importance of the FTTH technology risks, avoid blindly requiring full-service access. The existing FTTH technology mainly includes Passive Optical Network-PON (Passive Optical Network) Access Technology and Active Optical Network-A

Currently, passive labels use the following four cycle bands: 1) less than kHz 2) 13.56 MHz 3) UHF Band (860 ~ 960 MHz) 4) 2.45 GHz As shown in table 4, the labels of these weekly wave bands have different characteristics. 1) less than kHzPassive tags are powered by the reader, so the IC circuit cannot obtain a large current. In the era when low power and high cycle circuits cannot be developed, passive

Each of the three digits has different meanings.

established state, completes three times handshake. Handshake process in the packet is not included in the data, three times after the handshake, the client and the server began to transfer data officially. Ideally, once a TCP connection is established, the TCP connection is maintained until either side of the communication actively closes the connection. Confirmation Number: Its value is equal to the sender's send ordinal number +1 (the next serial number that the receiver expects to receive).

is a very common ha solution. But there are some serious problems with this solution.The first problem is overhead, especially when you want to run a large number of MySQL replication environments. The heartbeat +DRBD is a primary/standby solution, and therefore requires a passive (standby) master that does not handle any application traffic. Passive servers cannot be used for read extensions. Typically, y

If you do not understand the network, you can learn and explore it together. If you have any questions, you can add QQ or YY. (QQ: 914560310, YY: 283755973) "//" is not a command output or description.This time we will talk about the RIP version1 passive interface and unicast upd

FTP description: FTP is short for file transfer protocol. It refers to the file transfer protocol. The main function is to complete the file copy from one system to another. Like HTTP, HTTP is a widely used protocol on the Internet. The FTP protocol uses two TCP connections. One is the command link used to transmit commands between the FTP client and the server, and the other is the data link used to upload or download data. ============= First understanding ======== The FTP protocol can work in

message with a SYN flag to the server. This is the message 1 in the three-time handshake process.(2) server-side response to the client, this is the 2nd message in the three handshake, the message with both an ACK flag and a SYN flag. So it represents the response to the client's SYN message, and it also flags the SYN to the client and asks the client if it is ready for data communication.(3) The customer must again respond to the service segment an ACK message, which is the message segment 3.2

connection is established, the connection is called an FTP control connection. 2) Data Connection After the FTP control connection is established, you can start transferring files. The file transfer connection is called an FTP data connection. FTP data connection is the process of FTP data transmission. It has two transmission modes: Active Transmission Mode (port) and passive transmission mode (PASV ). In active transmission mode, the FTP server

Broadly speaking, FPGA configuration includes programming the FPGA device using the download cable, programming the external EEPROM and flash, programming the FPGA device using MPU, and programming the device using the external EEPROM and flash. FPGA Devices are configured in three categories: Active configuration, passive configuration, and JTAG configuration. Active configuration: the configuration process is guided by FPGA Devices.

other ports, even if some ports are connected to IPX or DECnet workstation. In this way, the bandwidth of non-TCP/IP nodes will be negatively affected. Even if the same TCP/IP node has the same subnet as the workstation that sent the broadcast packet, then they will receive some network broadcasts irrelevant to them for no reason, and the efficiency of the entire network will be greatly reduced. LAN switching devices have emerged since 1990s. From the perspective of network switching products,
