Abstract: The disclosure is related to a method for constructing hybrid network spanning trees, a method of redundancy, and a control system thereof. The method and system are adapted to a hybrid network system including at least one software-defined network (SDN) and at least one non-SDN network. In the method, a controller of the SDN is employed to collect network packets over the hybrid network. After analyzing the information carried in the network packets, the information relating to the topology can be obtained. Therefore, all the possible spanning trees can be constituted according to the topology. As well, the path delay and path bandwidth respectively for the SDN and non-SDN can also be obtained. The information allows the system to render utility function for every spanning tree. The most suitable spanning tree over the hybrid network system is applied. A mechanism of redundancy is also provided.

Abstract: Intersection signaling method for bearer management in a communication network with transporting bearer resource request message of both the UE and RN via Base station to managing entity of RN within EPC, as a signaling message over uplink channel referred to as ‘Union of Resource Request (UR Request)’ message. The bearer resource response message from one of the managing entity of UE or managing entities of UE and RN within EPC are transported as a signaling message to Evolved Packet Edge (EPE) via Base station over the downlink channel referred to as ‘Intersection of Admission Response (IA Response)’. This manages bearer setup signaling as a single loop, by transportation of ‘UR Request’ signaling message and receiving one “IA Response” signaling message over uplink and downlink channels respectively. EPE is a conglomeration of network nodes.

Abstract: A system and method which improve the performance of a wireless transmission system by intelligent use of the control of the flow of data between a radio network controller (RNC) and a Node B. The system monitors certain criteria and, if necessary, adaptively increases or decreases the data flow between the RNC and the Node B. This improves the performance of the transmission system by allowing retransmitted data, signaling procedures and other data to be successfully received at a faster rate, by minimizing the amount of data buffered in the Node B. Flow control is exerted to reduce buffering in the Node B upon degradation of channel qualities, and prior to a High Speed Downlink Shared Channel (HS-DSCH) handover.

Abstract: Session continuity may be maintained when communication devices transition from communicating through network infrastructure (e.g., through a cellular network) to direct mode communications (e.g., a communication path directly between two communication devices). For example, in switching from an infrastructure mode communication path to a direct mode communication path, a method may include: determining a public-facing address corresponding to the infrastructure path; replacing, for a packet that is to be transmitted over the direct mode communication path to a second communication device, a source address field of the packet with the determined public-facing address; and encapsulating the packet with source and destination address fields corresponding to the first and second communication device through the direct mode communication path respectively.

Abstract: A linear wireless sensor network includes network nodes having monotonically varying network node identifiers along each branch of the network. The network identifiers enable the nodes to forward network packets without use of routing tables. Low duty cycle wireless communication protocols enable network packets to be routed to all nodes of very large networks while consuming very little electrical power. Broadcast, rather than unicast, transmissions between nodes take advantage of favorable signal propagation conditions to forward messages using largest possible hops, skipping over nodes when possible, as well as automatically adapting to time- or spatially- varying conditions. A group of network packets is broadcast and forwarded by a most distant receiving node that received all packets of the group. A receiving node's clock is automatically adjusted, based on which packet(s) of a group of packets was received. A sending node synchronizes near-by receiving nodes.
