SBS-PFSK165-3BSE027778R1-VP74201-933CW07 交換機在端口上接受計算機發(fā)送過來的數(shù)據(jù)幀
以太網(wǎng)交換機是基于以太網(wǎng)傳輸數(shù)據(jù)的交換機,SBS-PFSK165-3BSE027778R1-VP74201-933CW07以太網(wǎng)采用共享總線型傳輸媒體方式的局域網(wǎng)。以太網(wǎng)交換機工作于OSI網(wǎng)絡(luò)參考模型的第二層(即數(shù)據(jù)鏈路層),是一種基于MAC地址識別、完成以太網(wǎng)數(shù)據(jù)幀轉(zhuǎn)發(fā)的網(wǎng)絡(luò)設(shè)備。
以太網(wǎng)交換機的結(jié)構(gòu)是每個端口都直接與主機相連,并且一般都工作在全雙工方式。交換機能同時連通許多對端口,使每一對相互通信的主機都能像獨占通信媒體那樣,進行無沖突地傳輸數(shù)據(jù)。
以太網(wǎng)交換機的工作原理是交換機在端口上接受計算機發(fā)送過來的數(shù)據(jù)幀,根據(jù)幀頭的目的MAC地址查找MAC地址表然后將該數(shù)據(jù)幀從對應(yīng)端口上轉(zhuǎn)發(fā)出去,從而實現(xiàn)數(shù)據(jù)交換。交換機分割沖突域,每個端口獨立成一個沖突域。每個端口如果有大量數(shù)據(jù)發(fā)送,則端口會先將收到的等待發(fā)送的數(shù)據(jù)存儲到寄存器中,在輪到發(fā)送時再發(fā)送出去。
以太網(wǎng)交換機應(yīng)用最為普遍,價格也較便宜,檔次齊全,因此,應(yīng)用領(lǐng)域非常廣泛。從幾個到幾十個端口都有,實質(zhì)上就是一個多端口的網(wǎng)橋。另外,它的端口速率可以不同,工作方式也可以不同。
此外,SBS-PFSK165-3BSE027778R1-VP74201-933CW07還有快速以太網(wǎng)交換機、千兆以太網(wǎng)交換機和萬兆以太網(wǎng)交換機等,這些交換機采用不同的協(xié)議標準或傳輸介質(zhì),但它們的基本工作原理和以太網(wǎng)交換機類似。
總之,以太網(wǎng)交換機是局域網(wǎng)中非常重要的網(wǎng)絡(luò)設(shè)備之一,它能夠?qū)崿F(xiàn)數(shù)據(jù)的高速傳輸和交換,提高網(wǎng)絡(luò)的性能和可靠性。

Ethernet switch is based on Ethernet data transmission switch, SBS-PFSK165-3BSE027778R1-VP74201-933CW07 Ethernet using the shared bus transmission media mode of the local area network. Ethernet switch works at the second layer (data link layer) of OSI network reference model. It is a network device based on MAC address identification and Ethernet data frame forwarding.
The structure of the Ethernet switch is that each port is directly connected to the host, and generally works in full-duplex mode. The switch can communicate with many pairs of ports at the same time, so that each pair of hosts communicating with each other can transmit data without conflict as if they were exclusive communication media.
The working principle of Ethernet switch is that the switch accepts the data frame sent by the computer on the port, searches the MAC address table according to the destination MAC address of the frame header, and forwards the data frame from the corresponding port to achieve data exchange. The switch divides conflict zones and creates an independent conflict zone for each port. If a large amount of data is sent to each port, the port will first store the received data waiting to be sent to the register, and then send out when it is the turn to send.
Ethernet switches are the most widely used, the price is also cheaper, the grade is complete, therefore, the application field is very wide. From a few to dozens of ports, it is essentially a multi-port bridge. In addition, its port rate can be different, the way it works can also be different.
In addition, SBS-PFSK165-3BSE027778R1-VP74201-933CW07 also has fast Ethernet switches, Gigabit Ethernet switches and ten Gigabit Ethernet switches, etc. These switches use different protocol standards or transmission media, but their basic working principle is similar to Ethernet switches.
In short, Ethernet switch is one of the most important network equipment in local area network, which can realize high-speed data transmission and exchange and improve the performance and reliability of the network.
