Systems and methods provide communications between applications in terminal nodes and applications agents in access nodes. The APP-agent cooperative communications can be used to improve quality of experience for users or the terminal nodes. An access node may, for example, have a parameterized scheduling system that incorporates information from the APP-agent cooperative communications in determining scheduling parameters. An application at a terminal node may, for example, modify requests for communication based on information about communication capabilities received from an access node. For APP-agent cooperative communications for multiple applications, an access node may include a master application agent to facilitate and coordinate communications to specific application agents that address APP-agent cooperative communications for specific applications. Similarly, a terminal node may use a master application and specific applications for APP-agent cooperative communications.

Systems and methods can use client-side video buffer occupancy for enhanced quality of experience in a communication network. The systems and methods provided herein can drive changes in the communication system using control responses. Example control responses include responses for scheduling of packets under capacity constrained conditions. An access node, such as a base station, may transmit video from a server to a client in a user device. The access node can estimate client-side video buffer occupancy and predict video playback stalls. The client-side video buffer occupancy can be estimated by emulating behavior of the client. The buffer occupancy can be used to enhance quality of experience for the user. For example, when the buffer occupancy is low, the access node may increase scheduling priority of packets conveying the video.

This disclosure provides a system and method for secure communications. The method can enable secure machine-to-machine communications within discrete security groups having two or more communication nodes using a zero knowledge authentication process and related cryptography. A first node in the security group can encrypt payload data using a synchronized data set known to the member nodes of the security group and a parameter data set. A second node in the security group can decrypt the payload data using the seed and the parameter data set. The seed can be provisioned within each node of the security group. The seed can also be provided or changed by a node or another entity to modify the security group membership. Member nodes of the security group can be added or removed as needed. Nodes not having the SDS cannot communicate securely with security group member nodes.

Secure communications using organically derived synchronized processes

This disclosure provides a system and method for secure communications. The method can enable secure machine-to-machine communications within discrete security groups having two or more communication nodes using a zero knowledge authentication process and related cryptography. A first node in the security group can encrypt payload data using a synchronized data set (SDS) known to the member nodes of the security group. The SDS can have a seed. A second node in the security group can decrypt the payload data using the seed. The seed can be provisioned within each node of the security group. The seed can also be provided or changed by a node or another entity to modify the security group membership. Member nodes of the security group can be added or removed as needed. Nodes not having the SDS cannot communicate securely with member nodes.

A method for predicting available bandwidth for a candidate flow on a link in a distributed network includes obtaining information about a plurality of flows carried by the link, the information including a current bandwidth consumption for each of the flows carried by the link; identifying whether each of the flows carried by the link has a local constraint or a remote constraint; and computing the available bandwidth for the candidate flow based at least in part on the information about the flows carried by the link and the identification of whether each of the flows carried by the link has a local constraint or a remote constraint. The predicted available bandwidth can be used to predict bandwidth consumption for active flows. The predicted available bandwidths can be used in selecting file block placement options.

File block placement in a distributed network

Pipelines for distributing file block in distributed file system network can be determined using a crawler algorithm. The crawler algorithm can iteratively identify links in a pipeline from for a starting node to one or more data storage nodes. In each iteration the pipeline can be extended based on the costs associated with the links on the pipeline with the resulting cost propagated as the pipeline is extended. The link costs indicate congestion on the links. Costs may also be back propagate from the data storage nodes.

Organically Derived Synchronized Processes provide encryption parameter management in a certificate-less system. A first node generates a parameter data set containing multiple values; uses a seed value stored at the first node to select values from a random parameter data set to form a parameter subset; generates encryption parameters using the subset; encrypts user data using the encryption parameters; generates a signature based at least on the parameter data set; and transmits a start frame including the parameter data set, the encrypted user data, and the signature. A second node receives the start frame; uses a seed value stored at the second node to select values from the received parameter data set to form a parameter subset; generates decryption parameters using the subset; decrypts the user data using the decryption parameters; and verifies the received signature. The encryption and decryption parameters are then applied to further payload data.

Systems and methods for optimizing system performance of capacity and spectrum constrained, multiple-access communication systems by selectively discarding packets are provided. The systems and methods provided herein can drive changes in the communication system using control responses. One such control responses includes the optimal discard (also referred to herein as 'intelligent discard') of network packets under capacity constrained conditions. The systems and methods prioritize packets and make discard decisions based upon the prioritization. Some embodiments provide an interactive response by selectively discarding packets to enhance perceived and actual system throughput, other embodiments provide a reactive response by selectively discarding data packets based on their relative impact to service quality to mitigate oversubscription, others provide a proactive response by discarding packets based on predicted oversubscription, and others provide a combination thereof.

Systems and methods provide communications between applications in terminal nodes and applications agents in access nodes. The APP-agent cooperative communications can be used to improve quality of experience for users or the terminal nodes. An access node may, for example, have parameterized scheduling system that incorporates information from the APP-agent cooperative communications in determining scheduling parameters. An application at a terminal node may, for example, modify requests for communication based on information about communication capabilities received from an access node. For APP-agent cooperative communications for multiple applications, an access node may include a master application agent to facilitate and coordinate communications to specific application agents that address APP-agent cooperative communications for specific applications. Similarly, a terminal node may use a master application and specifications for APP-agent cooperative communications.

Systems and methods for cooperative applications in communication systems

Systems and methods for uplink (UL) and downlink (DL) communications can improve channel capacity between one or more access nodes and one or more terminal nodes. The communications may utilize, for example, multi-user multiple-input multiple-output techniques with cooperation between access nodes. A network node may determine an ordering combination and associated pre-weighting values, provide the pre-weighting values to one or more terminal nodes, receive signals transmitted from the terminal nodes using the pre-weighting values; and process the received signals using the ordering combination and the pre-weighting values. Two constraints can be jointly used: a minimum performance constraint and a maximum transmit power constraint. Example systems search all possible ordering combinations to find a best combination, for example, the ordering combination that maximizes communication rates. The ordering combination may be used with combinations of full or partial successive interference cancellation in receivers and full or partial iterative pre-cancellation pre-coding in transmitters.

Enhanced pre-ordered pre-weighted transmission

A network node, and a method for operating a network node, such as a base station, may transmit multiple video streaming sessions from servers to clients in terminal nodes and can estimate client-side video buffer occupancy levels associated with the streaming sessions. To estimate a client-side video buffer occupancy level, the network node analyzes packets communicated with the terminal nodes to identify application layer messages and extract transaction information, determine payload types associated with objects conveyed in the packets identified with application layer messages, and associate the objects conveyed in the packets identified with application layer messages with one of the streaming sessions. The network node may use the estimated video buffer occupancy levels to determine scheduler parameters for use in scheduling packets for transmission to the terminal nodes. Packet scheduling may also be based on quality of experience considerations associated with streaming session clients in the terminal nodes.
