audio bandwidth 中文意思是什麼
-
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。 -
