packet broadcast
解釋
分封廣播-
On the internet, multimedia services such as streaming media, video / audio conference, voice over ip and video on demand, become more and more important, end - to - end data transmission or unicast ca n ' t be competent for the task which have the characteristic of one - to - many transmission. if we use unicast, the server has to offer the packet with same context for each connection, which will consume too much bandwidth. then the broadcast is alternative selection for us to deliver data in the lan, as we known, when broadcast technology used, all the pcs in the lan will receive the broadcast packets regardless that you would like to or not
點對點傳輸的單播方式不能適應此業務的傳輸特性（單點發送多點接收） ，這使得服務器必須為每一個接收者提供一個相同內容的ip報文拷貝，並在網路上重復地傳輸相同內容的報文，這必然佔用大量網路資源。雖然ip廣播允許一個主機把一個1p報文發送給同一個網路的所有主機，但是由於不一定是所有的主機都需要這些報文，這又可能浪費大量網路資源。 -
In this way, flooding of service requests is avoided. however, gsd causes much packet redundancy since that one unicast request packet is sent to each candidate node. two technologies, fnc ( forward node combination ) and bsu ( broadcast simulated unicast ), are proposed to improve gsd
雖gsd存在明顯的問題，但其基於組的服務需求包智能轉發技術是非常值得借鑒的，為此本文提出了轉發節點集中技術和單播通信廣播模擬技術以彌補gsd的問題。 -

The network activity display shows critical network utilization and broadcast information graphed against a packet traffic reference line. this display can show you the health of a lan at a glance and can warn of impending slowdowns due to broadcast or multi - cast storms
網路活動顯示網路活動顯示表示關鍵的網路利用率和廣播信息，繪制為分組話務參考線。此顯示表明 -
You can broadcast to your local subnet by sending a packet to 255. 255. 255. 255 ; or, you can use the directed broadcast address, which is the network portion of an internet protocol address with all bits set in the host portion
可以通過將數據包發送至255 . 255 . 255 . 255來廣播到本地子網；或者，也可以使用定向廣播地址，該地址為主機部分設置了所有位的internet協議（ ip ）地址的網路部分。 -
For internet protocol version 4, you can broadcast to your local subnet by sending a packet to 255. 255. 255. 255 ; or you can use the directed broadcast address, which is the network portion of an internet protocol address with all bits set in the host portion
對于internet協議版本4 ，可通過向255 . 255 . 255 . 255發送數據包來向本地子網廣播；也可以使用定向廣播地址，即internet協議（ ip ）地址的網路部分，同時所有位都在主機部分設置。 -
In computer networks, a packet switched system at the university of hawaii which uses radio broadcast techniques
美國夏威夷大學開發的一種使用無線電廣播技術的分組交換計算機網。 -
The traditional unicast and broadcast ca n ' t meet the demand of point to multi - points communication for cooperative design, ip multicast is the novel transport protocol to solve this question. it permits that a source in the network once delivers a packet to an arbitrary number of receivers. so it can retrench the network resources and enhance the transmission efficiency
傳統的點到點通信和廣播通信不能適應協同設計中這種點到多點的通信需求， ip多播正是針對此類問題提出的一種新型網路傳輸方案，它允許一個ip節點將一個報文一次發送給網路上的一組特定節點，可以節省網路資源，有效提高網路傳輸效率。
