不要忘记你加州大学的网络计划

第一个VOIP部署以来,工程师和建筑师在绩效管理中挣扎。而“扔带宽问题”是一个可行的解决方案只有敏感的应用程序时的声音,引入视频作为加州大学方程式的一部分,再加上增加其他延迟敏感交通意味着一个成功的加州大学实现需要密切关注网络性能指标包括延迟和抖动。现在简单的“服务质量”是发展到一个新的术语——应用程序交付优化(ADO),这不仅包括优先级的流量,而且包工具,如缓存、流控制、压缩和速率塑造为网络管理人员提供一套全面的管理工具处理整个网络上的应用程序。工程网络应用程序交付是富有挑战性的,因为目标不断移动。几年前,主要可能是关注移动文件,或优化的前景/交换流量,当今的企业正在迅速走向更新的和难以理解的水域。新的应用程序正在迅速,许多需要大量的带宽和实时性能。他们是高度可见的用户(没有什么比滚动视频的质量,例如),因为应用程序是新的合作模式和客户服务的关键,他们不是可选的。新的架构和应用极大地改变性能需求包括语音IP (VoIP),语音和视频会议、和其他协作工具;数据中心整合;软件即服务(SaaS); and desktop virtualization. Moreover, organizations need not just capacity and conditioning but control: the ability to ensure capacity is going to applications according to their priority. They must prioritize traffic in fairly granular ways, especially with media sharing a continuing concern and recreational use of bandwidth-intensive social media and other sites still on the rise. Video conferences should not suffer because there is a new hot video on YouTube. Access to critical SaaS applications must take priority over basic Web browsing or even over other, less-critical SaaS services. And there’s a cost component. With 21% of organizations paying IT for WAN bandwidth, at an average of $60/Kbps—the business lines have a strong incentive to demand the best performance for their money. They will press for meaningful performance guarantees in their SLAs, and so IT staffs will have ever-stronger incentive not only to deliver the performance but to be able to verify they are doing so for any and all applications (i.e. that the network is not the problem, if there is one). To deliver new services to users in an evolving branch and telework environment, IT may need to compress traffic to conserve bandwidth, but must condition network traffic to guarantee acceptable performance. The organization must also control traffic to ensure capacity goes to applications according to their organizational priority, and not to recreational or social media sites. As business lines increasingly have to pay IT for their bandwidth, IT having visibility into traffic, control over it, and the ability to condition traffic will be essential not just to meeting user expectations but also business line SLAs. Now is the time for organizations to take a close look at their application optimization systems and plans. They should: -Evaluate new application requirements and performance to gauge the suitability of current WAN and optimization. -Be prepared to upgrade, replace, or supplement current solutions for new use cases or traffic types. -Expect an increase in real-time and fault-intolerant traffic, if not an increase in bandwidth. -Optimize for the shift in traffic flows as a result of IT centralization and data center consolidation. -Optimize for the shift of traffic associated with desktop virtualization. -Control, monitor, secure, and optimize traffic with SaaS providers and other direct-to-Internet branch traffic. -Plan on providing optimization and security to progressively more numerous and smaller endpoints: big branches become mini branches become teleworkers. Cheap hardware or robust, affordable soft clients are key.
