    • A wireless access point may be configured to advertise, to mobile user devices, multiple wireless networks available through the wireless access point. For example, service set identifiers (SSIDs) may be specified within an information element (IE) of a communication such as, for example, an 802.11 beacon, broadcasted to mobile user devices. Such an IE may utilize the capability provided by IEEE 802.11 itself to use additional and flexible numbers of information elements within a beacon. Accordingly, networks that would otherwise remain hidden due to limitations of known wireless access points are made visible to mobile user devices. Configuring a wireless access point to advertise multiple available wireless networks, for example, by firmware upgrades, may serve as a viable and cost-effective interim solution and/or alternative to replacing a wireless access point with a wireless access point configured to implement virtual wireless access points.
    • 无线接入点可以被配置为向移动用户设备通告通过无线接入点可用的多个无线网络。 例如,可以在广播到移动用户设备的通信例如802.11信标的信息元素(IE)内指定服务集标识符(SSID)。 这样的IE可以利用由IEEE 802.11本身提供的能力来使用信标内的附加和灵活数量的信息元素。 因此,由于已知无线接入点的限制而否则将保持隐藏的网络对于移动用户设备是可见的。 配置无线接入点以发布多个可用的无线网络,例如通过固件升级,可以作为一种可行和具有成本效益的临时解决方案和/或替代无线接入点的替代方案,该无线接入点配置为实现虚拟无线 接入点

    • A system and method for ensuring that machines having invalid or corrupt states are restricted from accessing network resources are provided. A quarantine server located on a trusted machine in a network provides a bill of health to a quarantine agent located on a client computer that wishes to gain access to network resources administered by an organization. The quarantine agent requests bill of health from the quarantine server, and receives a manifest of checks that the client computer must perform. The quarantine agent then sends a status report on the checks back to the quarantine server. If the client computer is in a valid security state, the bill of health is issued to the client. If the client computer is in an invalid state, the client is directed to install the appropriate software/patches to achieve a valid state. When a client requests the use of network resources from a network administrator, the network administrator requests the client's bill of health. If the bill of health is valid, the client is admitted to the network. If the bill of health is invalid, or if the client does not have a quarantine agent, the client is placed in quarantine, in which the only network resources accessible to the client are those necessary to install the quarantine agent and requisite software/patches to achieve a valid state.
    • 提供了一种用于确保具有无效或损坏状态的机器被限制访问网络资源的系统和方法。 位于网络中的受信任计算机上的隔离服务器为位于客户端计算机上的隔离代理提供健康清单,希望访问组织管理的网络资源。 隔离代理从隔离服务器请求健康状况,并收到客户端计算机必须执行的检查清单。 然后,隔离代理将检查的状态报告发送到隔离服务器。 如果客户端计算机处于有效的安全状态,则会向客户端发送健康证明。 如果客户端计算机处于无效状态,客户端将被指示安装相应的软件/修补程序以实现有效状态。 当客户端请求网络管理员使用网络资源时,网络管理员请求客户的健康状况。 如果身体健康状况有效,客户可以进入网络。 如果健康状况无效,或客户端没有隔离代理,则客户端将被隔离,客户端可访问的唯一网络资源是安装隔离代理程序和必需的软件/修补程序所必需的网络资源 达到有效状态。

    • The generation and delivery of key frames to clients of a video conference are performed in response to a need for a synchronization point. Instead of automatically sending a key frame periodically to each of the clients in the video conference, a key frame is sent to one or more clients upon the occurrence of an event in the video conference. For example, a key frame may be sent to a client when the client joins the video conference. A key frame may also be sent to a client that has packet loss, upon the request of a client, a speaker change within the video conference, when a new stream is added by the client, and the like. The clients in the video conference that are not affected by the event continue to receive predicted frames.
    • 响应于对同步点的需要,执行视频会议的客户端的关键帧的生成和传送。 视频会议中的每个客户端周期性地自动发送关键帧,而不是在视频会议中发生事件时将关键帧发送给一个或多个客户端。 例如,当客户端加入视频会议时,关键帧可以发送给客户端。 当客户端添加新流时,关键帧也可以被发送到具有分组丢失的客户端,根据客户端的请求,在视频会议内的扬声器改变。 视频会议中不受事件影响的客户端继续接收预测帧。
