User equipment (UE), such as a mobile device, identifies data congestion and transmits a recommended data rate modification wireless signal (e.g., a recommended reduced data rate) to the base station that is transmitting data to the UE. The base station may reduce the data rate of the down link (DL) to the reduced data rate. The UE may then receive data from the base station at the reduced data rate. Therefore, flow control may be implemented at the base station side (e.g., sometimes referred to as the Network (NW) side) based upon the reduced data rate modification determined and transmitted by the UE to the base station. In this way, the data rate transmission to the UE can be reduced to allow the UE to successfully process received data and successfully perform its functions. | 12-09-2010 |

The algorithm involves: first determining what should be considered a very high or a very small value for a RTT sample. If a new RTT sample is in an acceptable range, then the network device performs a relatively basic smoothing. If the new RTT sample is much higher than a current RTT value, then the network device ignores the value of this RTT sample a few times. If the network device still detects this large value after ignoring that value for some time, then the network device factors this value into the current RTT value using an additive increase. Similarly, if the value of the new RTT sample is much lower than current RTT value, the network device ignores the value of the new RTT sample a few times. If the network device still sees this small/low value after ignoring that value for sometime, then the network device factors this value into the current RTT value using a multiplicative decrease.

| 20120155274 | DENIAL OF SERVICE (DoS) ATTACK PREVENTION THROUGH RANDOM ACCESS CHANNEL RESOURCE REALLOCATION - A system and method to substantially prevent Denial of Service (DoS) attacks due to Random Access Channel (RACH) overload in cellular wireless networks.

| 20160165479 | MULTI-CHANNEL MESH NODES EMPLOYING STACKED RESPONSES - Rather than using a large number of transceivers (transmitter/receiver pairs) operating in parallel, Access Points with multiple channels are used to aggregate, or stack, transmitted response communications, e.g., transmitting multiple acknowledgements (ACKs) in a single packet to one or more sources of received packets. The method includes sending on a plurality of channels, by each of a plurality of respective first nodes, a communication to a second node, receiving on the plurality of channels, by the second node, the communication from each of the plurality of first nodes and sending, by the second node, a transmission that contains a response to each communication that was successfully received from each of the plurality of first nodes. The response to each of the plurality of first nodes is part of a single message sent by the second node. | 06-09-2016 |
| 20160165481 | DATA TRANSMISSION METHOD AND APPARATUS - Embodiments of the present disclosure provide a data transmission method and an apparatus. The method includes: receiving, by user equipment UE, indication information sent by an access node of a cellular access network, where the indication information includes a filtering condition, and the indication information is used to instruct the UE to transmit, by using a wireless local area network WLAN, a traffic flow that meets the filtering condition; determining, by the UE according to the indication information, that a first traffic flow meets the filtering condition; and transmitting, by the UE, the first traffic flow by using the WLAN. Therefore, according to an indication of the access node of the cellular access network, the UE may choose to transmit the traffic flow by using the WLAN, thereby improving data transmission efficiency. | 06-09-2016 |

| 20160191402 | Reduction of Network Congestion - A technology is provided for reducing network congestion. A data loss rate pertaining to a datastream between a client and a server may be determined. The datastream may comprise data packets sent and received between the client and the server. The client and the server may send to and receive from each other data packets encoded using random linear network coding (RLNC) in response to determining that the data loss rate is higher than or equal to a threshold. | 06-30-2016 |
| 20160192233 | CONGESTION CONTROL FOR A MULTIMEDIA SESSION - Congestion control is achieved by assigning flow identifiers to media flows sharing source and destination addresses. Performance measurements between a sender and a receiver and/or routers are performed and used to detect a congestion state for a flow route in a transport network. A media flow, a media rate to adapt to combat the congestion state, is identified based on the assigned flow identifiers and mapping information defining a mapping between flow routes and flow identifiers. | 06-30-2016 |

| 20160380909 | PROVIDING QUALITY OF SERVICE FOR CONTAINERS IN A VIRTUALIZED COMPUTING ENVIRONMENT - An example method is provided for a computing device to provide quality of service (QoS) for a container in a virtualized computing environment. The method may comprise receiving a traffic flow of packets from a virtual machine and identifying a container from which the traffic flow originates based on content of the received traffic flow of packets. The container may be supported by the virtual machine. The method may further comprise retrieving a QoS policy configured for the identified container. For example, the QoS policy may specify a network bandwidth allocation for the container. The method may further comprise forwarding the received traffic flow of packets according to the QoS policy. | 12-29-2016 |
| 20160381594 | METHODS, SYSTEMS AND APPARATUS FOR MANAGING AND/OR ENFORCING POLICIES FOR MANAGING INTERNET PROTOCOL ("IP") TRAFFIC AMONG MULTIPLE ACCESSES OF A NETWORK - Methods, systems and apparatus for managing and/or enforcing one or more policies for managing internet protocol (“IP”) traffic among multiple accesses of a network in accordance with a policy for managing bandwidth among the multiple accesses are disclosed. Among the methods, systems and apparatus is a method that may include obtaining performance metrics associated with the multiple accesses. The method may also include adapting one or more rules of one or more the policies for managing IP traffic among the plurality of accesses based, at least in part, on the performance metrics and the policy for managing bandwidth among the plurality of accesses. The method may further include managing IP traffic associated with at least one wireless transmit and/or receive unit (“WTRU”) among the plurality of accesses responsive to the adapted rules. | 12-29-2016 |
| 20160381596 | INTELLIGENT MULTI-BEAM MEDIUM ACCESS CONTROL IN KU-BAND FOR MISSION-ORIENTED MOBILE MESH NETWORKS - A MAC design for Ku-band mobile wireless mesh network with multi-beam smart antennas is disclosed. This MAC includes an overlay control that separates the collision domain. It also has lower layer CSMA-like scheme. The disclosed design includes an enhanced PCF and an enhanced DCF for two purposes: (1) exploiting multi-beam concurrent communication capability (2) supporting QoS and mission-based communications. An efficient time synchronization scheme is also disclosed to ensure all beams can concurrently send data to the star node. Finally, ARMA or HMM based prediction schemes are disclosed to predict future traffic profile in each beam. This helps the star node to better prepare the queue content and schedule information. | 12-29-2016 |
