最近，ACG Research公布了Y最新的全球交換機和路由器市場份額的資料。比薩餅大概如上圖所示。Cisco還是老大，Juniper還是千年的老二。任部華為名列第五。

這種marketing數據其實有許多噱頭。通過不同的細分，或者產品規模，讀者可以得到許多不同的圖表。

總的來說，Cisco的ASR9000很拉風，是主力產品，拉動Edge的巨大市場。整了2端口的100G的線卡。更是笑傲江湖。

從蘋果與西紅柿的角度，J的相應產品是Trio based MX960系列；H是ME80等。目前來看，華為最缺的還是自己的chipset。VRP應該是有不錯的基礎了，在老吳的鞭子下：－）。Forwarding要加油呀：－（

Concerns over the high level of global government debt, especially in Europe and slower economic growth in the US, Europe and emerging countries, which may stumble into a recession, are impacting the Worldwide Carrier Routing & Switching markets. The global market decreased 4.3% sequentially and grew slightly 1.8% year over year, according to ACG Research. The Total Worldwide Carrier Routing & Switching market grew revenue $2.8B in Q3/11. Core Routing revenues were down 3.9% q/q but up 4.2% y/y. Edge Routing and Switching revenues were down 4.4% q/q but up 1.1% y/y.

With 54.5% of the total market share, Cisco, the market leader, is capitalizing on the trend of its customers simplifying the way their networks work and how next-generation Internet can be more visual, mobile and virtual. The company has posted 3.9% growth in edge routing, largely attributed to successful ASR 9000 momentum. Juniper holds the number two spot with 18.1% and continues to gain traction with its strategy of capitalizing on mobile, Internet and cloud computing and solutions portfolio. Alcatel-Lucent, which is benefiting from the market momentum for 100G IP/optical as well as providers replacing and leveraging 100GE and IPv6 transition technologies has 16.5% of the total market share.

According to Ray Mota, managing partner, “Many carriers are letting emotions get in the way of fundamentals regarding the economy. Carriers need to understand that volatility in markets is normal, and they must understand what is driving the volatility in order to make sound investment decision for expansion of networks or development of new services.” They need to control emotions and look at economic fundamentals, for example, the US GDP grew 2.5% in Q3, the UK grew 0.5%, and India grew 7.7%. So, focus on fundamentals, allow expansion and promote cautious growth by controlling cost on the operational side and expanding into new services related to enterprise-productive services, such as mobility and video/CDN experience enhancements.”
