    • A system and method of performing device detection and service discovery in a mobile ad hoc communications network, each network node storing a local application directory. One of the network nodes is selected to be a directory server node that stores a combined application directory. The directory server node sends an inquiry message to a listening node when the listening node enters the coverage area of the directory server node. The listening node sends a notification message to the directory server node that includes the local application directory stored in the listening node. The directory server node compares the received local application directory to the combined application directory and updates the combined application directory accordingly. The directory server node sends an update message to each network node by sending an update portion of the combined application directory. Each network node updates the local application directories accordingly.
    • 一种在移动自组织通信网络中执行设备检测和服务发现的系统和方法,每个网络节点存储本地应用目录。 其中一个网络节点被选择为存储组合应用程序目录的目录服务器节点。 当监听节点进入目录服务器节点的覆盖区域时,目录服务器节点向侦听节点发送查询消息。 监听节点向目录服务器节点发送包含存储在侦听节点中的本地应用目录的通知消息。 目录服务器节点将接收到的本地应用程序目录与组合的应用程序目录进行比较,并相应地更新组合的应用程序目 目录服务器节点通过发送组合的应用目录的更新部分向每个网络节点发送更新消息。 每个网络节点相应地更新本地应用程序目录。

    • A computer system, method, and computer program product for locating target devices that support a required service in an ad-hoc communications network. The ad-hoc communications network connects devices and support services. Each target device is one of the devices and the required service is one of the services. The method comprises conducting an inquiry of the ad-hoc communications network to discover nearby devices. If the inquiry indicates that the nearby devices may include a middleware layer, the method further comprises creating a connection to each of the nearby devices and confirming whether each of the nearby devices includes the middleware layer. For each of the nearby devices that includes the middleware layer, the method further comprises sending a service discovery request, and receiving a response that includes distributed information. The distributed information includes associations between the services such as the required service, and the devices such as the target devices.
    • 一种用于定位在自组织通信网络中支持所需服务的目标设备的计算机系统,方法和计算机程序产品。 自组织通信网络连接设备和支持服务。 每个目标设备是其中一个设备,所需的服务是其中一个服务。 该方法包括进行自组织通信网络的查询以发现附近的设备。 如果查询指示附近的设备可以包括中间件层,则该方法还包括创建到每个附近设备的连接并且确认每个附近的设备是否包括中间件层。 对于包括中间件层的每个附近设备,该方法还包括发送服务发现请求,以及接收包括分布式信息的响应。 分布式信息包括诸如所需服务的服务之间的关联以及诸如目标设备的设备之间的关联。

    • An advanced traffic shaper is provided for shaping real-time traffic in an IP-based network while simultaneously providing keep-alive bandwidth for best-effort traffic. The traffic shaper comprises a packet classifier coupled to receive an incoming packet from the network and to classify the incoming packet as one of a real-time packet and a best-effort packet; a packet discarding block coupled to perform traffic shaping of the incoming packet from the packet classifier and discard the incoming packet in accordance with traffic shaping parameters; connection queues coupled to temporary store real-time packets and best-effort packets from the packet discarding block, respectively; and a packet scheduling block coupled to send the real-time and best-effort packets from the connection queues to an outgoing device in accordance with the traffic shaping parameters.
    • 提供先进的流量整形器,用于在基于IP的网络中整形实时流量,同时为尽力而为的流量提供保持活动的带宽。 流量整形器包括分组分类器,其耦合以从网络接收输入分组,并将输入分组分类为实时分组和尽力而为分组之一; 一个分组丢弃块,用于对来自分组分类器的入局分组进行流量整形,并根据流量整形参数丢弃该分组; 连接队列分别耦合到临时存储来自分组丢弃块的实时分组和尽力而为的分组; 以及分组调度块,其被配置为根据流量整形参数将来自连接队列的实时和尽力分组发送到输出设备。
