The global mobile backhaul market space from 9.7 billion in 2009 to 11.7 billion in 2011. The fastest-growing fiber optic Ethernet solution, annual growth rate of more than 185%; 2009 is the cultivation period, the market space of 410 million (including PTN / LSW / Router); in 2010 the market space is 1 billion; in 2011 began to scale, market Space is 1.6 billion. Other means (DSLAM, ME, PON) benefit the vast majority of the old current network / fixed network resources, due to less new investments of mobile.HUAWEI TECHNOLOGIES CO., LTD.

Main region of PTN Swap
Our MSTP stock market has gone beyond the ALU, occupy the first position of the world. In China, Middle East and other regional sales rank well. And a slight decline in the CIS market. 1SDH technology is mature, Huaweis huge stock market will continue to contribute to profits. 2CIS,Mexico, South Africa, South Asia, Europe is still ALU and the NSN site, huaweis market share is less than other vendors 3Global SDH stock market is about 50 billion U.S. dollars, nearly 5 billion a year of the replace opportunities.HUAWEI TECHNOLOGIES CO., LTD.

Philosophy Compare of PTN VS Router
Mesh topology, Mesh traffic
Ring/Tree topology Aggregation traffic
PTN is more suitable for backhaul network where the traffic is aggregated to RNC and topology is fiber ring or microwave links.
