A telecommunications edge cloud (TEC) element deployed between a client and a packet network includes a TEC hardware layer including storage resources, networking resources, and computing resources, wherein the computing resources include a plurality of processors. A TEC operating system (TECOS) is coupled to the TEC hardware layer and configured to control and manage the storage resources, the networking resources, and the computing resources, wherein the TECOS is executed by one of the processors, a TEC application layer coupled to the TECOS, wherein the TEC application layer is configured to process a request from the client using the TECOS, wherein the computing resources are configured to provide a service to the client when the request is a service request, and wherein at least one of the networking resources and the storage resources is configured to provide data to the client when the request comprises a data request.

A system and method for network virtualization and resource allocation, including storing one or more received network requests in a request table, and updating at least one of a flow table, a waiting list table, or a candidate group map based on the one or more received network requests. The updating includes monitoring a transmission progress of each of one or more flows in a network of interconnected computing devices and moving completed flows from the flow table to a success list, moving requests in the waiting list table which have reached an attempt threshold from the flow table to a fail list, and compiling any residual requests in the waiting list with new requests to generate a new request table. A deterministic request allocation and/or an optimizing request allocation is performed based on the new request table.

A system and method for management of network traffic flow for one or more networks of interconnected computing devices, including predicting one or more types of network traffic data flows using a Machine Learning (ML) classifier, and updating the ML classifier according to identified changes in the network traffic data flows.

Methods and systems for variable rate control include determining a new communications rate in response to measured data traffic patterns. A receive change message is transmitted to a receiver that triggers the receiver to wait for an end of transmission (EoT) message and to set a new communications rate. A transmit change message is transmitted to a transmitter that triggers the transmitter to send the EoT message to the receiver, to set the new communications rate, and to send a start of transmission (SoT) message to the receiver before resuming data communications.
