Abstract:
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.
Abstract:
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.
Abstract:
The bandwidth of a virtual circuit is changed when the aggregate bandwidth available on path(s) to an adjacent ATM device (through which the VC is provided) changes. The change of bandwidth may be implemented by changing the QoS parameters associated with the virtual circuits. Thus, for example, when one of the paths becomes non-operational, the bandwidth of a virtual circuit may be reduced in a fair manner.
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:
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.
Abstract:
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.
Abstract:
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.

Abstract:
Several keep-alive messages of point to point (PPP) sessions received from a remote system are aggregated into a single packet in an aggregation device (e.g., network access server). The aggregated packet is sent to a peer aggregation device (e.g., home gateway) at the other end of the PPP session. The peer aggregation device may send the status of the sessions in a single packet. As a result, the data traffic on a communication backbone due to keep-alive status checks may be reduced. Without waiting for the peer aggregation device to provide the status information, a proxy reply may be generated from the aggregation device.
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.
