中文摘要 | 同步光纖網路正在被廣泛地佈建作為光纖傳輸之標準基礎架構,用以支援現有之寬頻電路交換服務,以及未來包括利用小封包之新式服務。現今之服務以及網路設備是專為對稱性交通而設計。隨著政策之發展,視訊服務已逐漸顯現成為電信業者將來一新興市場所在。視訊服務將會耗用網路上相當大的頻寬,但其雙向流量本質上卻極不對稱。具備非對稱特性的同步光纖網路設備可預見的將會很快出現於市場上。本篇論文描述各種不同的網路結構,並對於這些結構如何能用於支援非對稱交通及對稱性交通做一比較,同時藉由簡單範例來說明適切的網路設計對於整體網路成本能產生相當大的影響。 |
英文摘要 | SONET is being widely deployed as the standard fiber optic transport infrastructure for existing wideband and broadband circuitbased services and for new and future broadband services including cell-based services. Current services as well as network equipment are based exclusively on symmetric traffic. As the regulatory climate changes, video services have gradually emerge as a new source of increasing future revenues for telecommunications carriers. Video services will consume large amounts of bandwidth across broadband networks, but are highly asymmetric in nature. It is expected that new SONET equipment with asymmetric characteristics to appear on the market soon. This paper describes different network architectures and how they cab be used for the asymmetric transport, in comparison to the current symmetric use. A simple example tries to illustrate that proper network design has a tremendous impact on capital spent on the network. |
