对CRS-1的看法

对CRS-1得看法既然HFR对於CISCO解决其现在公司内部技术架构有重大意义，我们就来把HFR作为一 个CASE STUDY来调查一下，试图从中发现一些CISCO过去的痛苦和对将来的期盼。 我们先来看一下一个CISCO HFR(HUGE FASTR ROUTER) 方面的新闻。 2004年5月25日，CISCO终於公布了其姍姍来迟的最高真个ROUTER。www.lightreading.com是 这样发布评论的。 连接LINKhttp://www.lightreading.com/document.asp?doc_id=53319 Cisco Systems Inc. (Nasdaq: CSCO - message board) unveiled its next-generation core router today, a move that some analysts believe could herald the overhaul of Cisco&＃39;s entire product line, even down to enterprise boxes (see Cisco Launches HFR ). The long-awaited HFR is a multichassis "terabit" router meant to compete with boxes from Avici Systems Inc. (Nasdaq: AVCI - message board; Frankfurt: BVC7), Chiaro Networks Inc., Hyperchip Inc., Juniper Networks Inc. (Nasdaq: JNPR - message board), and Procket Networks Inc. After more than four years in development, the box is *** its debut today under its real name: the Carrier Routing System, or CRS-1 (no word on whether rapper KRS-ONE has been tapped as a spokesman). The CRS-1 truly is huge and fast, with a capacity of 640 Gbit/s in a 7-foot rack. It scales to 72 shelves rather than the 18 reported by sources, for an unreal 46 Tbit/s maximum capacity, or 1,152 OC768 ports. (Cisco reports this as 92 Tbit/s, using its usual convention of counting ingress and egress capacity separately.) But CRS-1 wasn&＃39;t intended to be just a big router, says Mike Volpi, senior VP and general manager of Cisco&＃39;s Routing Technology Group. Rather, Cisco wanted to start afresh to build an IP box that would suit telecom carriers&＃39; needs for years to come. The software is engineered to produce the "permanent and continuous operation" demanded in the voice network, Volpi says. "It&＃39;s designed to be Class 5-like in its carrier manageability." 读者请留意： (1)。 分析职员以为HFR将带来CISCO所有产品线(包括ENTERPRISE企业方面的OVERHUAL(全 面检查，或全面结构性的考察)。笔者註：通常我们说一个产品是设计给TELCOM/CARRIER的 或给ENTERPRISE的。这两方面是很不同的对产品的要求。) (2) 「Long-awaited" HFR...为什麼说」期待已久的「HFR？期待了多久？做了4年 半！只有4。5年吗？从开始规划到5/25/04，6年都有了。几乎每个从CISCO出来的或 在那里的都知道这个项目。一个太重要，太不可能完成的项目了。 HFR或CRS-1仅仅是一个高速的ROUTER吗？不是，不仅仅是。HFR而且是CISCO的下一 代完整的操纵系统。我们下面再来读一下这方面的摘要。 」......Most significantly, the CRS-1 deviates from Cisco&＃39;s Internetwork Operating System (IOS), the software that runs on nearly all its platforms. The new software is called IOS XR, but it&＃39;s been built from scratch. The transition is analogous to Microsoft Corp. (Nasdaq: MSFT - message board) moving from DOS-based operating systems to Windows NT, says analyst Stephen Kamman of CIBC World Markets. Just as NT did, IOS XR could begin trickling down to lower-level systems, eventually permeating Cisco&＃39;s e        1/4 1234下一页尾页
