Agora

问题：A)为了降低成本和提高效率，公司越来越多地使用视频会议（VC）进行部门会议、培训、面试和会见客户。公司希望通过将新的、具有成本效益的、基于软件的解决方案与现有的硬端点（终端内部摄像机、麦克风和视频显示器）相结合，以经济地增强风险投资能力。B)公司现有的硬风险投资设备和基础设施（专用的风险投资服务器）是昂贵的（服务，维护，IT支持和培训），而且不够灵活，无法满足不断变化的需求。c)公司内部和外部公司/个人使用的所有风险投资系统（硬和软）之间的完全互操作性是必不可少的。然而，存在许多不同的VC系统（20+），它们之间的互操作性有限，导致严重的可靠性问题。D)为了支持各种不同端点的互操作性，需要对视频通话中涉及的所有VC系统进行外部管理和控制。然而，这是由安全系统，如防火墙和代理服务器用于保护企业网络阻止。这是所有VC管理公司面临的主要问题。*项目将如何解决问题：本项目将创建一个Agora的原型，这是一个软件应用程序，它将使UCi2i能够穿越防火墙和代理服务器，在应用程序编程接口（API）级别上控制视频通话中涉及的所有VC设备。Agora将使：A)公司通过增加新的灵活的软端点来增强风险投资能力，而不存在与现有设备的兼容性问题。B)公司使用他们现有的VC设备，而不需要昂贵的专用网络来支持它。c)未注意到的设备故障和不正确的VC设置导致大多数视频通话失败（UCi2i, 2012）。Agora将允许UCi2i远程监控设备并调整视频通话中使用的所有VC端点的设置，以确保可靠性和互操作性。

*The Problem:A) To reduce costs and increase efficiency companies are increasingly using VideoConferencing (VC) for departmental meetings, training, interviews and meeting customers.Companies want to enhance VC capabilities economically by combining new, cost-effective, software based solutions with existing hard endpoints (endpoints house camera, microphone and video display).B) Companies existing hard VC equipment and infrastructure (dedicated VC servers) isexpensive (service, maintenance, IT support & training) and not flexible enough to meetchanging needs.C) Complete interoperability is essential between all VC systems (hard and soft) both within a company and those used by external companies/individuals. However many different VC systems (20+) exist with limited interoperability between them, causing serious reliability issues.D) To support the interoperability of a wide range of different endpoints, externalmanagement and control of all VC systems involved in a Video Call is required. However,this is prevented by security systems such as firewalls and proxy servers used to protectcorporate networks. This is a major problem facing all VC management companies.*How project will address the problem:This Project will create a prototype of Agora, a software application that will enable UCi2i totraverse firewalls and proxy servers to control, at an Application Programming Interface(API) level, all VC equipment involved in a video call. Agora will enable:A) Companies to enhance VC capabilities by adding new flexible soft endpoints, withoutcompatibility issues with existing equipment.B) Companies to use their existing VC equipment without needing an expensive dedicatednetwork to support it.C) Unnoticed equipment failure and incorrect VC settings cause most video call failures(UCi2i, 2012). Agora will allow UCi2i to remotely monitor equipment and adjust settings ofall VC endpoints used in a Video Call to ensure reliability & interoperability.
