Free Loop

基本解釋

One limitation that applies to hubs and switches alike is that an Ethernet network must be loop-free.
集線器和交換機(jī)有同一個侷限，即以太網(wǎng)網(wǎng)絡(luò)必須是無路由循環(huán)的。
OSPF detects changes in the topology, such as link failures, very quickly and converges on a new loop-free routing structure within seconds.
OSPF探測在拓?fù)溲e的變化，如鏈路失敗。非常迅速地，幾秒內(nèi)便在新的自由環(huán)路（loop-free）路由結(jié)搆裡滙聚。

Based on the analyses of traditional routing schemes proposed for satellite networks, a discrete time based loop-free routing algorithm (DTRA) for LEO satellite networks was developed.
在分析傳統(tǒng)衛(wèi)星網(wǎng)絡(luò)路由算法的基礎(chǔ)上，提出一種基於分時的LEO衛(wèi)星網(wǎng)絡(luò)無環(huán)路由算法（DTRA）。

The firm maintains that it had been pitching its patented noise cancellation to Apple in periodic meetings between 2007 and 2010, only to watch as 1 Infinite Loop used Audience's technology for the iPhone 4 instead -- and supposedly handed some of Noise Free's work to a competitor.
