A controller is provided for use with a CD, a WAN, and a service provider server, the HNC includes: a memory; and a processor configured to execute instructions stored on memory to cause the HNC to: establish a priority time period; associate the priority time period with a first application; establish a first service flow queue having a first QoS during priority period; establish a second service flow queue having a second QoS; receive first upstream packets and second upstream packets; assign the first upstream packets to a first upstream queue during the priority time period; assign the second upstream packets to a second upstream queue; receive first downstream packets and second downstream packets; assign the first downstream packets to a first downstream queue during the priority time period; and assign the second downstream packets to a second downstream queue.

The described technology is generally directed towards a transport protocol for latency sensitive applications. The disclosed transport protocol is “semi-reliable” in that it allows for specification of an importance of data being transmitted, thereby allowing important data to be sent reliably, while other data can be dropped if necessary, e.g., under bad network conditions. A deadline can be specified for such other data, and if the other data cannot be sent prior to the deadline, it can be dropped. Furthermore, the disclosed transport protocol can allow for early discovery of network jitter. A client device can send regular acknowledgments which identify most recently received data packets as well as a number of “heartbeat transmissions” received at the client device. A server device can use the acknowledgments to discover and respond to jitter.

A discrimination method to be executed by a discrimination device that discriminates an application, includes collecting packet data and first flow data that satisfy a predetermined rule, analyzing the packet data and generating a signature that associates the application and an IP address with each other, generating second flow data from the packet data, calculating first feature amount information that is a statistical feature amount for each IP address for the first flow data, and calculating second feature amount information that is a statistical feature amount for each IP address for the second flow data, attaching a label to the second feature amount information with use of the signature, and causing a discriminator to learn discrimination of the application by using the first feature amount information and the second feature amount information as learning data.

Technology related to application deployment across network devices including smart network interface cards. In one example, a method includes distributing an application across a plurality of locally connected computing subdomains. The subdomains can include a mixture of general and special purpose computing subdomains, such as for example, a main computer and an associated smart network interface devices or systems, such as for example a smart network interface card (NIC). The subdomains can each run hypervisors that are bridged to allow a single virtual machine to operate across the subdomains. The application can include multiple portions. For example, an application can be split by different functionalities. The application portions can be tagged to indicate which subdomain they are to be executed within. If the chosen subdomain has available the requisite resources, the application can be detached and distributed to the chosen subdomain.

Aspects of the present disclosure include a content delivery network (CDN) for delivering content associated with a plurality of different types of applications/devices. Using a CDN flow application, a plurality of network flow parameters are generated for content delivery unique to different types of applications or devices. The network flow parameters include customized data transmission rates. The network flow parameters include predetermined settings for transmission control protocol (TCP) connections between the CDN and devices using a TCP flow control mechanism. Upon receiving a content request, the CDN fulfills the content request based upon first network flow parameters. The network flow parameters may be adjusted for each of the plurality of different types of applications/devices. The network flow parameters may be generated based upon requests or based upon the performance of each of the plurality of applications/devices.
