Abstract: An example method involves, when a first quality of service parameter for a failed logical circuit is equal to or less than a second quality of service parameter for a logical failover circuit, rerouting data from the failed logical circuit to the logical failover circuit without requiring authorization from a customer to communicate the data at the second quality of service parameter. When the second quality of service parameter for the logical failover circuit is a lower level of quality than the first quality of service parameter for the failed logical circuit: a customer is prompted for an authorization to communicate the data via the logical failover circuit at the second quality of service parameter; when the authorization is received, the data is rerouted from the failed logical circuit to the logical failover circuit; and when the authorization is denied, the data is not rerouted to the logical failover circuit.

Abstract: Disclosed is a multicast system and a multicast method using a shortened address and an apparatus applied to the same. The multicast system using the shortened address according to the present disclosure has a address configuration for supporting a multicast in an IEEE 802.15.4 MAC (Medium Access Control) layer. Accordingly, when a device processes a multicast through an address configuration of the MAC layer, the device receives the multicast through a simple scheduling such as receiving a beacon signal of a coordinator device only when there is a broadcast of a group including the device. As a result, the device can efficiently perform the multicast in a power managing process or a power processing process.

Abstract: Some embodiments provide a method for encoding video pictures captured by a mobile device having at least first and second cameras. The method identifies a first rate controller parameter that is based on at least a first value that quantifies one characteristic of the first camera. The method uses the first rate controller parameter to configure a set of rate controllers to adjust a bit rate for encoding video pictures captured by the first camera. The method identifies a second rate controller parameter that is based on at least a second value that quantifies the same characteristic of the second camera. The first and second values are different, and the difference causes the first and second rate controller parameters to be different. The method uses the second rate controller parameter to configure the set of rate controllers to adjust a bit rate for encoding video pictures captured by the second camera.

Abstract: A method for detection of a network address translation (NAT) device in a network is described herein. An edge network device detects a first packet at an edge port of the edge network device. A second packet is detected at the edge port of the edge network device. It is determined whether a time to live (TTL) value associated with the first packet is different from a TTL value associated with the second packet. Where the TTL value associated with the first packet is different from a TTL value associated with the second packet, it is determined that a NAT device is connected to the edge port. Where the TTL value associated with the first packet is the same as a TTL value associated with the second packet, it is determined that a NAT device is not connected to the edge port.

Abstract: Systems and methods for improving data transmission rates in communication networks are disclosed. In an 802.11 wireless communication network, where a source node of the wireless network transmits TCP data to a destination node of the wireless network, the destination node does not transmit TCP acknowledgments (ACKs) for the TCP data if 802.11 ACKs indicate that the destination node received the TCP data. If a source outside the wireless network transmits TCP data to the destination node within the wireless network through an intermediate device, such as an access point, the destination node suppresses transmitting TCP ACKs. The intermediate device transmits TCP ACKs as proxy for the destination node to the source. The intermediate device also suppresses TCP ACKs where a source node within the wireless network sends the TCP data to a destination node outside of the wireless network.

Abstract: A data processing section selects either base station mode or terminal mode and executes communication. A control section controls operations relating to the base station mode and the terminal mode. A receiving section receives an instruction to switch to the base station mode from other wireless device set in the base station mode, in the case where communication is set in the terminal mode. An AP switching section switches to the base station mode in accordance with the instruction. An instructing section instructs other wireless devices set in the terminal mode to switch to the base station mode, after a predetermined period is passed from the time when the mode is switched to the base station mode. An STA switching section switches to the terminal mode after giving the instruction.

Abstract: A technique for performing layer 2 processing is described. In a method implementation of this technique, at least one first RLC SDU is created from one or more first RLC PDUs. It is assumed here that the first RLC SDU belongs to an incomplete RLC SDU set that is to comprise at least one second RLC SDU, and that the second RLC SDU is to be created from at least one second RLC PDU not yet available. In a next step, a first PDCP function is applied to the first RLC SDU to create a data packet. The RLC function is only performed after the second RLC PDU has become available (or after an RLC time-out). Then, after the RLC function has been performed, the data packet is released to a second PDCP function.
