在网络中集成应用程序的价值
现代商业对网络的要求比以前更多。当今的网络需要支持各种媒体类别——包括数据，语音和视频——去增强商业通讯和降低运营成本。当成千上万的新设备通过无线或者有线连入网络时，访问方式已经发生了变化。
为解决日益紧迫的挑战，企业需要他们的网络具有智能化的，并在易于管理的安全应用中扮演一个积极地角色。智能化网络集成了很多高级应用到一个能够自适应、无所不在的和共同协助的系统中。
集成安全性：在当今的环境中，一个混合的单点产品解决方案不再是充分的保护措施。网络安全必须被广泛地集成到网络架构的每个组织。网络成为一个抵御和响应来自内部和外部安全威胁的主要管控点。一种集成的策略包括多种保护的类型，其中令人关注的是有关网络对于识别、防御和适应安全威胁的改善增加。这样的系统可以帮助增强信息隐私、抵御威胁和控制公司资源访问。
IP通讯：语音、视频和其他数据类型被整合到一个网络中。IP通讯——包括：具有有短信和语音信箱的IP电话；客户联系程序；音频，Web和多媒体会议工具——显示了智能网络的力量。与基础架构紧密集成意味每个新的应用——视频，Web或者电话——与其说是一种新的媒体类型还不如说一个完整的不同的通讯系统。应用程序本身能够在基础架构智能化通讯以满足不断变化的系统需求。
无线：无线不能被看作是一个独立的应用，特别是当无线接入点增加到成百上千时。一个智能化的网络提供了这样架构，这个架构提供给无线局域网解决方案所能获益的现有的有线网络架构中的工具、知识和资源去引导解决无线局域网安全、部署和控制等问题。
基于IP的语音、无线和安全是在高级应用中最重要的，因为这些应用正强烈地改变着商业运作的方式。企业必须关心怎样才能最好的利用他们现有的网络，以便他们的公司能持续地从新的应用获益，并快速的、便于得到安全化、有效进行管理的达到其商业的目标。

The Value of Integrating Applications in the Network
Businesses today demand more from their networks than ever before. Networks today now need to support all forms of media——including data, voice, and video——to enhance business communications and lower operating costs. Access has also changed, as thousands of new devices connect to the network via wireless and wired connections.
To solve these pressing challenges, organizations need their networks to contain intelligence and play an active role in securely integrating applications in a way that is easy to manage. Intelligent networks integrate many advanced applications into an adaptable, pervasive, and collaborative system.
Integrated Security: In today's environment , a mix of point-product solutions is no longer sufficient protection. Network security must be pervasive and integrated into the fabric of the network infrastructure itself. The network becomes the main point of control for preventing and responding to security threats from internal and external sources. An integrated strategy includes multiple types of protection and dramatically improves the ability of networks to identify, prevent, and adapt to security threats. Such systems help to ensure information privacy, protect against threats, and control access to corporate resources.
IP Communications: Voice, video, and other types of data are woven into a converged network. IP Communications—which includes IP telephony as well as unified messaging and voicemail; customer contact applications; and audio, Web, and rich-media conferencing tools—demonstrates the power of an intelligent network. Tight integration into the infrastructure means that each new application—video, Web, or telephony—is just another media type rather than an entirely different communications system. The applications themselves can intelligently communicate with the infrastructure to meet the constantly changing needs of the system.
Wireless: Wireless cannot be viewed as an isolated application, especially when wireless access points scale into the hundreds or thousands. An intelligent network provides the framework that enables a wireless LAN solution to take full advantage of existing tools, knowledge, and resources of the wired infrastructure to address critical wireless LAN security, deployment, and control issues.
IP-based voice, wireless, and security are only the first in a new wave of advanced applications that are beginning to powerfully change the ways in which businesses operate. Organizations must consider how they can best enable their networks today so that their companies can continuously take advantage of new applications quickly, secure them easily, and manage them efficiently in pursuit of their business goals. |
