Abstract: A link device facilitating communication between a wireless communication terminal and a resource-constrained device. According to an aspect, the link device receives messages from the wireless communication terminal on a wireless path according to a first protocol, converts the messages into a second protocol, and forwards the converted messages in the second protocols to the resource-constrained device on a wired path connecting the link device to the resource-constrained device. In an embodiment, the first protocol corresponds to HTTP protocol and the second protocol corresponds to a simpler protocol which requires relatively lesser processing and memory resources.

Abstract: Setting up a group of virtual circuits using a single set up message request. In an embodiment, fewer than all of the virtual circuits in the group are immediately provisioned, and the remaining virtual circuits are placed in an inactive status by appropriate configuration of all the devices in the path of the group of virtual circuits. Each of the inactive virtual circuits can be activated (complete provisioning) as and when required. The bandwidth overhead on the networks is reduced as fewer signaling messages would be used in provisioning several virtual circuits. The parsing overhead is reduced on the devices processing the signaling messages as a result.

Abstract: A switch may be configured to support a point-to-multi-point PVC which can be used to support a point to multi-point application. The signaling overhead is reduced due to the use of PVC, and the available bandwidth is used efficiently due to the use of the point-to-multi-point connection. Another aspect of the present invention minimizes the resources required while providing such point-to-multi-point virtual connections. A switch may minimize allocation of resources to branches that are not active. For example, a switch may determine that a branch is inactive based on the absence of reception of OAM cells in a specified duration and delete the forwarding information for the inactive branch. The switch may thus scale to support many point-to-multi-point virtual circuits having many branches.

Abstract translation: 交换机可以被配置为支持可以用于支持点到多点应用的点对多点PVC。 由于使用PVC，信令开销降低，并且由于使用点到多点连接，可用带宽被有效地使用。 本发明的另一方面使提供这种点对多点虚拟连接所需的资源最小化。 交换机可以将资源的分配最小化到不活跃的分支。 例如，交换机可以基于在指定持续时间内不存在OAM小区的接收来确定分支是不活动的，并且删除非活动分支的转发信息。 因此，交换机可以缩放以支持具有许多分支的许多点到多点虚拟电路。

Abstract: An access point communicates with a wireless station based on a point-to-point channel, to determine time instances of future communication to be received from the wireless station. In intervals between such future communications, the access point powers down at least some portions of a circuit contained within the access point for at least a partial duration between such future communications. In an embodiment, the powered-down portions include the receiver portions of the access point. The access point may be battery-powered, and the powering-down of the receiver portions enables reduction of power consumption in the access point.

Abstract: A wireless station (A) is operated in a power-save mode, in which the station is alternately in power-ON and power-OFF states to reduce power consumption. Wireless station (A) computes at least some future time instances at which another wireless station (B) is expected to start transmitting control messages. Wireless station (A) is ensured to be in the power-ON state in corresponding time intervals encompassing durations of at least some of such future transmissions of control messages by wireless station (B), and is thereby enabled to receive the control messages. In an embodiment, the control messages correspond to group key message updates in which values of a decryption key are transmitted, wireless station (A) being a wireless client, wireless station (B) being an access point, with wireless stations (A) and (B) operating in a wireless network consistent with IEEE 802.11 specifications, and communication between wireless stations (A) and (B) being encrypted.

Abstract: The services offered (e.g., bandwidth) by a PVC can be changed, potentially as and when desired. An end system (of a PVC) may send a request to initiate a change of a service. Each intermediate system may first determine whether the service change can be supported, and passes the request to the next system in the path until the request is received by the other end system of the PVC. Assuming the other end system also can support the change, an acceptance response is propagated in the reverse direction of the same path. Each system may effect the service change upon receiving the acceptance response.

Abstract translation: 由PVC提供的服务（例如，带宽）可以根据需要进行改变。 一个PVC的终端系统可以发送一个请求来启动服务的更改。 每个中间系统可以首先确定是否可以支持服务改变，并且将该请求传递到路径中的下一个系统，直到PVC的另一端系统接收到该请求。 假设另一端系统也可以支持改变，则接收响应在相同路径的相反方向上传播。 每个系统可能在接收到接受响应后影响服务改变。

Abstract: An edge router receives datagrams to be forwarded an SVC. If the SVC is not already set up, the edge router buffers the datagrams until the SVC set up is complete. The buffered datagrams are forwarded once the SVC set up is complete. According to another aspect of the present invention, different buffering requirements are supported for different user applications. A policy table may be configured by a service provider specifying the requirements associated with potentially each flow (e.g., combination of source/destination IP addresses, source/destination port number), and the datagram on each flow may be buffered accordingly.

Abstract translation: 边缘路由器接收要转发SVC的数据报。 如果尚未设置SVC，则边缘路由器会缓冲数据报，直到SVC设置完成。 SVC设置完成后，缓存的数据报将被转发。 根据本发明的另一方面，不同的用户应用支持不同的缓冲需求。 策略表可以由服务提供商配置，其指定与潜在的每个流相关联的要求（例如，源/目的地IP地址的组合，源/目的地端口号），并且可以相应地缓冲每个流上的数据报。

Abstract: A network device (e.g., network access server or home gateway) providing different QOS (quality of services) to different layer-3 datagrams when transporting on tunnels. A tunnel may be implemented to provide different QOS to different packets depending on the packet header. The network device examines the header of each datagram to determine the specific QOS to be provided. At least the data portion in the datagram is encapsulated for transportation on the tunnel. The encapsulated data portion in turn is encapsulated in the form of one or more packets, with the packet format to reflect the QOS determined for the datagram. When the tunnel is implemented on UDP/IP and the datagram is an IP (Internet protocol) datagram, the TOS/Precedence bits of the IP datagram may be copied into the precedence/TOS bits of the UDP/IP packet(s).

Abstract translation: 当在隧道上运输时，向不同的第三层数据报提供不同的QOS（服务质量）的网络设备（例如，网络接入服务器或家庭网关）。 可以实现隧道以根据分组报头向不同的分组提供不同的QOS。 网络设备检查每个数据报的头部以确定要提供的具体QOS。 至少数据报中的数据部分被封装以在隧道上传输。 封装的数据部分依次以一个或多个数据包的形式进行封装，分组格式反映了为数据报确定的QOS。 当隧道在UDP / IP上实现并且数据报是IP（因特网协议）数据报时，IP数据报的TOS /优先级位可以被复制到UDP / IP数据包的优先级/ TOS位。

Abstract: An aspect of the present disclosure enables an access point (AP) to conveniently provision multiple wireless devices. In an embodiment, the AP may normally operate in a secure mode to disregard non-secure provisioning requests from wireless devices. However, upon receipt of a request to accept provisioning requests from multiple wireless devices, the AP permits multiple wireless devices to be provisioned via the AP, in response to corresponding provisioning requests received from the respective wireless devices. The request to accept may be generated upon pressing of a push button provided on the AP, which may be referred to as a group provisioning button since multiple wireless devices are provisioned in response to pressing of that button.

Abstract translation: 本公开的一个方面使得接入点（AP）能够方便地配置多个无线设备。 在一个实施例中，AP可以通常以安全模式操作以忽略来自无线设备的非安全供应请求。 然而，在接收到接收来自多个无线设备的供应请求的请求时，AP响应于从相应的无线设备接收到的相应的供应请求，允许通过AP来供应多个无线设备。 可以在按下设置在AP上的按钮时产生接受请求，该按钮可以被称为组配置按钮，因为响应于该按钮的按压提供了多个无线设备。
