下面是在Networkers大会上思科和50个CCIE对于此项目的讨论摘要，当然这些并不是最终的认证情况，仅供参考。
Some of the engineers felt strongly that a current CCIE should be a prerequisite for the CCDE. However, an equal number disagreed, including myself. Cisco really sees the CCIE as a technology certification - how to make the actual equipment work. The CCDE, and the subsequent Architecture certification, is focused on network design, not necessarily making equipment work. The analogy given by one of the CCIEs summed it up well - "an architect of a home isn’t the general contractor; he doesn’t actually build the home. He just needs to know how the pieces interact (fit).”
Many people offered ideas for the format of the "performance oriented scenario test". The goal is to make it just as hard as a CCIE lab is, but it's not a lab. Thoughts about responding to an RFP were tossed about.
The tentative timeline is to have the "scenario test" ready by March or April of next year for beta testing. The Architecture certification would come much later, perhaps a year or more. The written exam is available in two weeks for the beta testers to attempt. Most people agreed this is a good timeline.
While the format and rules of the new certification were strongly debated, everyone in the room agreed there is a need for this type of certification and were very excited. I'm sure people will be eager to take the beta written exam in a few weeks. The consensus was this is a good thing for the certification program, a benefit to the industry, and good for professional development.
Some other quick notes of comments made:
- People seemed to want to talk about the Architect certification more than CCDE.
- Need to create CCDE numbers. Initial group also wanted recognition as the pioneers of this credential.
- Make is multi-vendor (or vendor co-existent).
- Keep it standards based, perhaps even partner with a standards board.
- Allow people to take the CCDE "scenario" and attend Architect board via Telepresence and/or WebEx.
- Possibly use a team format for the CCDE scenario, like used in MBA programs.
- PLEASE be selective. Screen applicants, particularly beta candidates.
- Must create industry awareness. This is key to employer support and showing candidates the benefits of achieving the certifications. 现在已经有了针对此项目的Beta笔试，不过是需要邀请才能参加的，思科的目标是有200个人参加后再进行项目的完善，据说笔试的大纲有6页之多，从路由到Tunneling到安全，当然通过这个考试也算CCIE再认证之列。由于NDA的原因，目前参加此beta考试的人没有更多的消息透漏。

在目前的CCIE认证系列当中已经覆盖了路由交换方向，网络安全方向，运营商方向，存储方向和语音方向，而作为Design的设计方向是唯一没有的涉及的。早在2001年的时候思科就准备了一个面向设计方向的CCIE认证，但是最终没有落实，而近一段时间这个想法又开始提出，某些CCIE可能已经收到了思科的电子邮件，询问其对一系列新的认证的看法，涉及名称为Cisco Certified Master Internetwork Architect, Cisco Certified Master Network Architect, Cisco Certified Design Expert, Cisco Certified Network Architect, Cisco Certified Network Infrastructure Architect, 和 Cisco Certified Internetwork Expert – Design。思科的发言人也公开承认思科正在考虑设计方向的CCIE。据说2001年版本之所以失败是因为关于Lab考试的处理问题上，怎么通过动手实验的方式来测试网络设计呢？不过据说目前的版本已经解决了通过某种手段解决了此问题，不过思科没有公布具体的内容。下面根据参加了此项目的内部人士的报料来看看这个新认证。
首先是思科Beta Team发给CCIE的邮件内容：
This will be a collaborative effort with the Cisco CCIE and Network Design Professional community. Not only will it include complex network design principles, theory, and analysis, it will include multi-vendor high availability design and strategic infrastructure architecture concepts. At the highest level, this credential is intended to focus "beyond the network" where network design and architecture are leveraged to help grow an organization's respective business.
在Networkers大会上的部分讨论内容
Cisco has identified a need for certifying individuals with a high degree of experience and expertise in designing and architecting large-scale networks (over several hundred routers) at the routing layer.
The CCIE, while an extremely well respected certification, focuses on the device level configuration and operation of Cisco equipment. Network design is not part of those tests. Furthermore, for experienced design engineers and architects, the CCIE tracks do not fit their roles and needs anymore, yet the CCIE is the only avenue for industry recognition for people at their level. The concept for this certification came about because some of Cisco's earliest CCIEs are no longer interested in the CCIE's product and configuration focus since that is not part of their job anymore.
The new CCDE will be on par with the existing CCIE programs. It will have a written exam and then a "performance oriented scenario test which assesses a practitioner's advanced network design skills". The "scenario" format or process has not been developed yet. The intent is not to make it a "lab", but focus it on design. Thoughts about responding to an RFP or project plan were presented as options during the Q&A. The goal of the CCDE is to provide incentives for experienced network design practitioners to continue professional development.
The Network Infrastructure Architect (which is not officially named yet) will be feature a board review. Candidates to the board would have already completed the CCDE. The board would be made up of industry experts; likely Cisco employees, but not required. A candidate would have to present and defend a network design and architecture to the board. The expectation is the board review would be extremely rigorous, only for the most experienced engineers.

富源面馆是我第一次在银川时候旁边的一个面馆，主要是小揪面和羊脖子，生意很火。今天是在银川的最后一天，虽然下雨了但是还是去了一趟富源面馆。生意还是很火，内容还是揪面和羊脖子。一小碗揪面和小份羊脖子就把我撑的够呛，想着是最后一顿了，还是摸着圆肚皮继续吃下去。晚上就要回北京了，据说北京的项目会持续比较长的时间，虽然一直想安定的待在北京，但是真正要停下来的时候心里还是有点奇怪，也许在外面的日子太多了，我就是一个背着家的人，行李箱就是我的家。
大学毕业时候的梦想是在沙滩上摸着肚皮晒太阳，上网。现在发现摸着肚皮吃面的日子反而过的更舒服，希望回北京能发现更舒服的生活目标。
哦，今天是070809，挺有意思的日子，hehe

Viacom's Net Income Falls Slightly Following Year-Earlier Tax Benefit
By Kevin Kingsbury
Word Count: 519 | Companies Featured in This Article: Viacom, Sony
Viacom Inc.'s second-quarter net income slipped 0.8% following a year-earlier tax benefit and earnings from discontinued operations. Earnings surged at the company's movie business ahead of the July 2 release of "Transformers."
The owner of various cable networks and the Paramount and DreamWorks movie studios reported net income of $434 million, compared with $437.3 million a year earlier. However, per-share earnings rose to 63 cents from 61 cents as shares outstanding fell 4.6%.
The latest quarter's results include a $94 million gain from selling MTV's investment in Russia, partially offset by a $22 million charge to write off its investment ...

思科近日宣布要对其设计方向的CCDP专业认证进行更新，以提高目前面向服务网络（Service-Oriented Network）的设计和实施能力。现有的网络已经不是单纯的提供连通性，所以在网络设计上也要更多的面向服务，针对不同的应用，提高网络的智能性，设计一个高效的，高可用性的低成本的网络。
新版的CCDP使用的培训教程是Designing Cisco Network Service Architectures，也就是ARCH v2.0，目前是ARCH 1.2，考试号也变为642-873.目前是642-871.新版内容中据说有90%都是新的，用来反映当前思科的产品和解决方案。
新的ARCH课程的大纲都还没有提供，思科声称9月3日才有，新版的考试从10月11日开始可以注册考试，原来的871考试的最后考试日期为12月14日。
