    摘要: An end device in a network is designed to operate consistent with multiple versions of the internet protocol. The end device determines which version of the internet protocol, according to which the network is operative, by monitoring a set of packets on the network. Based on the determination of the version of internet protocol, the end device loads in an internal volatile memory only those instructions and data required for operation according to the determined version. Instructions and data required for operation according to other version(s) are not loaded into the volatile memory. Size requirements of the volatile memory are thereby reduced.

    摘要: 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.

    摘要: An end device operates as an access point to setup communication with a wireless station. Once the communication has been setup, the end device exchanges data packets with the wireless station while operating as an access point. The end device and the wireless station are included in a WLAN network according to IEEE 802.11 standards. Operation as an access point enables the end device to communicate with a large number of wireless stations. Such communication can be the basis for implementation of various management applications on wireless stations. In an embodiment, the end point includes a blood pressure sensor, and transmits (while operating as an access point) blood pressure measurements to a mobile phone operating as a wireless station.

    摘要: 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.

    摘要: A router providing differentiated services while transporting Internet Protocol (IP) packets on an asynchronous transfer mode (ATM) backbone. A network administrator may specify multiple precedence values (in the type of service (TOS) portion of an IP header) associated with each SVC (set up with desired QOS). IP packets with the specified precedence values are transported on the associated SVC. By associating different precedence values with different SVC and configuring different SVCs with different QOS, differentiated services may be provided to IP packets.

    摘要: An aggregation device providing different QOS to different point-to-point sessions. Multiple virtual circuits, each to provide different QOS, may be provisioned. The aggregation device may be configured to indicate the desired QOS for each point-to-point session and the data related to each point-to-point session may be assigned to a virtual circuit providing the closest matching QOS. Alternatively, a service provider may statically specify the specific virtual circuit on which the data related to a specific point-to-point session is to be transmitted. Each point-to-point session receives a QOS provided by the assigned virtual circuit. As the content of each datagram received on a point-to-point session may not need to be examined for the purpose of assignment to a virtual circuit, an aggregation device may forward datagrams quickly.

    摘要: A WiFi-enabled embedded device boots as a first access point. The WiFi-enabled embedded device communicates with a first wireless station to receive configuration parameters while continuing to operate as an access point. The WiFi-enabled embedded device then applies the configuration parameters internally to cause the WiFi-enabled embedded device to operate as a second wireless station. In an embodiment, the first wireless station discovers a configuration service advertized by the WiFi-enabled embedded device using mDN/DNS-SD, and automatically provides the configuration parameters to the WiFi-enabled embedded device. Convenient provisioning of the WiFi-enabled embedded device is thus made possible.
