Abstract: A central management system polls a lighting node in a mesh lighting network, sending a command message for the node to measure a link quality indication (LQI) of the received command message. The node returns a status message, including in its payload the measured LQI. The management system computes from the node's status messages, a statistical characterization of the link quality of the node and compares it with a threshold quality value. If the comparison indicates sufficient degradation in link quality, the management system automatically transmits a disconnect command to the node. In response, the node disconnects and enters a discovery mode to find a better quality link to rejoin the network. In example embodiments, the lighting node may also report its illumination and operational status in the payload of the status message, along with the LQI, enabling the management system to determine whether illumination by the node is failing.

Abstract: Destination endpoints can use in-band signaling to adjust TCP parameters, to adjust entries in history and profile tables, to initialize a transition to an in-band communication mode, or to communicate short flows and/or alerts to a mobile device. A destination endpoint achieves in-band singling by embedding sequence number patterns in acknowledgement (ACK) messages, or by transmitting ACK messages (duplicates or otherwise) in accordance with an ACK sequence pattern. The sequence number or ACK sequence pattern can be pre-associated with any in-band communication message, such as a request to adjust TCP parameters, the reporting of a network or triggering condition, a request to adjust entries in a history or profile table, an indication to transition from a normal communication mode to an in-band communication mode, etc.

Abstract: Selectively ignoring congestion conditions may allow for more efficient transmission control protocol (TCP) communication in instance where reducing the transmission rate for a flow will not meaningfully mitigate congestion in the network or is otherwise undesirable. By way of example, congestion conditions may be ignored when a specific type of traffic flow is being communicated (e.g., short flows, high priority flows, etc.), when a traffic flow is being communicated at a low transmission rate, when a traffic flow is destined for certain type of network (e.g., a wireless network, etc.), or during any other situation in which reducing the transmission rate is undesirable. In some networks, a transmission rate is maintained until a certain number of duplicate ACKs are received (e.g., three duplicate ACKs, etc.) in order to ensure that congestion is indeed present before reducing quality of service (QoS).

Abstract: Transport control protocol (TCP) parameters can be dynamically selected to increase communication network performance. The TCP parameters may be selected before usage or at start-up such that a TCP connection is dynamically configured/re-configured prior to transporting the traffic flow over the network. The TCP connection parameters may be selected in accordance with a traffic characteristic, a network characteristic, a history of traffic activity, expected loads, desired throughput and latency or some other selection criteria. TCP parameters may also be selected after beginning to transport traffic flows over the network. More specifically, transportation of a traffic flow over the network may begin immediately using default TCP parameters, with the TCP parameters being updated or selected only upon the occurrence of a congestion or triggering condition. Further, multiple clients may share a set of persistent time-shared TCP connections.

Abstract: A system and method wherein mobile nodes scan both 802.16 and 802.11 radio channels for neighbor access points. A mobile node reports both WiMax and WiFi neighbor access points to its parent access point.

A parent WiMax AP can direct a mobile node to roam to a neighbor WiFi access point that has a lighter load or offers enhanced services. As an option, a location tracking protocol is used to determine the location of a mobile node and the mobile node's parent AP advertises neighbor APs that offer services in the mobile node's location.

Abstract: Supporting communication sessions at a mobile node includes determining at a mobile node an address for one or more interior network elements of a network system. A interior network element is distinct from an edge network element of the network system, and is operable to establish a communication session. An address for an interior network element is inserted into packets. The packets are sent from the mobile node to the interior network element to communicate directly with the interior network element. The communication session is established using the interior network element.
