Disclosed are systems and methods for an optimal transmission rate for large quantities of data over a network using gambler strategies. The gambler strategies can include initiating a gambler of a generation including a plurality of gamblers and transmitting one or more packets for the gambler over a network at a transmission rate specified by the gambler. In response to a determination the gambler is finished the network to discharge. In response to a determination the generation is finished, determining a gain-loss of the generation and the plurality of gamblers can be adjusted to be inline with an inherent network data loss rate.

A control method executed by a control device includes detecting a notification to inform that switching of a line used for transferring packets by a first transfer device and a second transfer device is to be occurred; transmitting, to the first transfer device and the second transfer device, an instruction for requesting to transfer the packets to the control device; storing the packets received from the first transfer device and the second transfer device; transmitting, to the first transfer device and the second transfer device, a transfer rule for designating a line after the switching as an output destination of the packets to be transferred by the control device, when the switching occurred; reading the stored packets; and transmitting the read packets to the first transfer device and the second transfer device at a speed at which the read packets is transferable by using the line after the switching.

Various example embodiments for supporting deterministic communications in communication networks may be based on use of a hybrid Programming Protocol-Independent Packet Processor (P4) deterministic switch. The hybrid P4 deterministic switch may include an electronic communication element configured to compensate for the jitter of incoming traffic to match a desired level of jitter for end-to-end deterministic communication of the incoming traffic and an optical communication element configured to support optical propagation of deterministic traffic received from the electronic communication element. The electronic communication element may include electronic packet queues, programmable electronic schedulers serving the electronic packet queues, and a P4 control element, where the electronic packet queues, the programmable electronic schedulers, and the P4 control element cooperate to support end-to-end deterministic communication of traffic based on control plane programming of the programmable electronic schedulers to serve the electronic packet queues in a manner providing end-to-end deterministic communication of the traffic.

The embodiments described herein provide a router control system for routing data streams from a plurality of input ports to a plurality of output ports using at least one video router. Each router in the system comprises a backplane including a plurality of backplane connections, at least one line card and at least one fabric card. Each line card comprises a plurality of input ports and output ports, each input port and output port being coupled to a respective external signal through the backplane, and a line card cross-point switch having a plurality of input switch terminals and a plurality of output switch terminals, wherein a first plurality of input and output switch terminals are coupled to a respective plurality of input and output ports and a second plurality of input and output switch terminals are coupled to a respective plurality of backplane connections. Each fabric card comprises a fabric card cross-point switch having a plurality of input switch terminals and a plurality of output switch terminals, wherein the plurality of input and output switch terminals are coupled to a respective plurality of backplane connections. For each of the one or more video routers, the one or more configuration signals are configured to instruct selective coupling of one or more input switch terminals of a corresponding cross-point switch of one or more line or fabric card to one or more corresponding output switch terminals, and selectively control the operation of the corresponding one or more line or fabric card.

A system, process, and computer-readable medium for updating an application cache using a stream listening service is described. A stream listening service may monitor one or more data streams for content relating to a user. The stream listening service may forward the content along with time-to-live values to an application cache. A user may use an application to obtain information regarding the user's account, where the application obtains information from a data store and/or cached information from the application cache. The stream listening service, by forwarding current account information, obtained from listening to one or more streams, to the application cache, reduces traffic at the data store by providing current information from the data stream to the application cache.

Embodiments are disclosed for traffic engineering in support of real-time applications. A user equipment (UE) can detect a real-time application running on the UE, assess a link health corresponding to the real-time application, and transmit a payload including the link health to a peer device via WiFi communications. To detect the real-time application, the UE can receive traffic symptoms or application indications, and monitor corresponding traffic flows. To assess the link health, the UE can receive link quality metrics of a link corresponding to the link health, and determine an intra basic service set (BSS) clear channel assessment (CCA) percentage. The UE can initiate a Rapport session with the peer device, activate a keep-alive timer, and transmit updated information to the peer device according to the keep-alive timer.
