波長二次重用的雙向WDM星形單跳網(wǎng)

Bidirectional WDM star single-hop networks with reusing wavelengths twice

  • 摘要: 針對有限的數(shù)據(jù)信道波長數(shù)對波分復(fù)用星形單跳網(wǎng)容量的限制問題,文章提出了一種波長二次重用、單纖雙向傳輸和多耦合器內(nèi)連相結(jié)合的組網(wǎng)擴(kuò)容解決方法.與常規(guī)波分復(fù)用星形網(wǎng)相比,該方法不但將網(wǎng)絡(luò)所支持的節(jié)點數(shù)增加了兩倍;而且網(wǎng)絡(luò)的所有數(shù)據(jù)信道波長都得到二次重用,網(wǎng)絡(luò)最大吞吐量也增加了兩倍;在網(wǎng)絡(luò)節(jié)點數(shù)不變的條件下,不但可節(jié)省一半的光纖,而且通過波長的二次重用,可大大減小網(wǎng)絡(luò)中通信節(jié)點的排隊時延,緩和各通信節(jié)點對數(shù)據(jù)信道波長使用權(quán)的競爭矛盾,有效地改善網(wǎng)絡(luò)性能。
    Abstract: For enlarging the capacities of WDM star networks free from the number of limited wavelengths, a scheme of reusing wavelengths twice is proposed in this paper. According to the scheme, not only the number of nodes can be increased twice, but also all the data wavelengths can be reused twice in the network and the throughput of the network is increased twice. Under the same number of nodes, not only half of fibers can be saved, but also the delay of network can be greatly lowered and the properties of the network can be efficiently improved.
