style="text-indent:25px">集線器的發(fā)展產(chǎn)生了一種叫非管理型交換機的設備。它能實現(xiàn)消息從一個端口到另一個端口的路由功能，相對集線器更加智能化。非管理型工業(yè)交換機能自動探測每臺網(wǎng)絡設備的網(wǎng)絡速度。另外，它具有一種稱為"MAC地址表"的功能，上海工業(yè)交換機品牌排行榜，能識別和記憶網(wǎng)絡中的設備，上海工業(yè)交換機品牌排行榜。換言之，如果端口2收到一條帶有特定識別碼的消息，此后交換機就會將所有具有那種特定識別碼的消息發(fā)送到端口2。這種智能避免了消息，提高了傳輸性能，相對集線器是一次巨大的改進。然而，非管理型交換機不能實現(xiàn)任何形式的通信檢測和冗余配置功能，上海工業(yè)交換機品牌排行榜。以太網(wǎng)已經(jīng)成為工業(yè)控制領域的主要通信標準。工業(yè)交換機是以太網(wǎng)的重要組成。上海工業(yè)交換機品牌排行榜</p><div

style="text-indent:25px">絕大多數(shù)管理型工業(yè)交換機通常也提供一些高級功能，如用于遠程監(jiān)視和配置的SNMP(簡單網(wǎng)絡管理協(xié)議)，用于診斷的端口映射，用于網(wǎng)絡設備成組的VLAN(虛擬局域網(wǎng))，用于確保優(yōu)先級消息通過的優(yōu)先級排列功能等。利用管理型交換機，可以組建冗余網(wǎng)絡。使用環(huán)形拓撲結構，管理型交換機可以組成環(huán)形網(wǎng)絡。每臺管理型交換機能自動判斷較優(yōu)傳輸路徑和備用路徑，當優(yōu)先路徑中斷時自動阻斷(block)備用路徑。可網(wǎng)管交換機可以通過以下幾種途徑進行管理:通過RS-232 串行口(或并行口)管理、通過網(wǎng)絡瀏覽器管理和通過網(wǎng)絡管理軟件管理。江蘇萬兆工業(yè)交換機直銷同等功能的工業(yè)交換機要比商業(yè)交換機貴。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

交換機級聯(lián)。路口運用層采用了百兆光口匯聚，上行至監(jiān)控中心層使用千兆光口，這種梯度式帶寬設計，有效的解決了上行擁堵的問題，保證了整個網(wǎng)絡高效、高速的運行，使視頻更加順暢。并且此方案在監(jiān)控中心采用的是多光口的千兆設備，整個網(wǎng)絡采用星型拓撲結構，有效的減少了故障節(jié)點對整個網(wǎng)絡造成的影響。而且通信網(wǎng)絡主要采用光纖進行傳輸，避免了電磁干擾等對整個系統(tǒng)造成的影響，保證了系統(tǒng)的穩(wěn)定可靠運行。</p><p
