Abstract: An edge computing system comprises: a cloud computing system; an edge processing function; a connection between the edge processing function and the cloud computing system; a backend server within the cloud computing system. An assessment module is configured to receive information about processing goals, and processing capabilities of the backend server and the edge processing function. The assessment module derives a set of possible interfaces and corresponding functionality splits defining a division of processing activity between the backend server and the edge processing function. Based on a received measurement of bandwidth and/or of latency on the connection, the assessment module selects an interface and corresponding functionality split, and downloads them to the edge processing function and the backend server.

Abstract: An edge computing system comprises an application store, an edge server and a cloud computing system comprising a backend server. The edge server is configured to receive an application from the application store with additional information defining capabilities of the edge server that are required for the application to run on the edge server and/or capabilities of devices connected to the edge server. The edge server determines whether the application can run, and indicates the result to the application store. The edge server keeps a record of applications that can start to run and/or continue to run, when the edge server is or becomes disconnected from the cloud computing system. The application store keeps records of successful application downloads, and of edge servers that indicated they could not run applications.

Abstract: A network entity is provisioned to support cloud services for a mesh network that includes at least one edge node. The network entity comprises: a processor, operably coupleable to a content store; and a content agent registry coupled to the processor and configured to identify content to be delivered to the at least one edge node. The content agent registry records at least one attribute against the content to be delivered based on a characteristic of the content.

Abstract: A communication device that transmits data segments over an interface, wherein the communication device comprises transmission management logic. After receipt of a data segment for transmission over the interface, the transmission management logic determines a sequence number of a data segment to be transmitted and compares the sequence number of the data segment to be transmitted with at least one pending sequence number of a previous data segment. Based on the comparison, the transmission management logic either discards the data segment to be transmitted if the sequence number of the data segment matches the at least one pending sequence number of the previous data segment; or adds the sequence number of the data segment to the at least one pending sequence number and transmits the data segment if the sequence number of the data segment does not match the at least one pending sequence number.

Abstract: An apparatus, method, and computer-readable medium encoded with executable instructions for Transmission Control Protocol (TCP) flow control in a communication system are provided. According to embodiments of the invention. TCP flow control includes determining delay in a transmit buffer of the system; and modifying TCP window size based on the determined delay and a target transmit buffer delay. An indication of a modified TCP window size is sent to a TCP server of the system in an acknowledge packet. Embodiments of the invention are particularly suitable for TCP flow control in wireless communication systems (e.g., UTRA) systems, and has the advantage that RTT (i.e., the latency of the system) can be substantially guaranteed, irrespective of the throughput that a user is allocated.
