  • Patent number: 11451481
    Abstract: A data collection unit of an NW controller (6) collects, from an L2SW (5) constituting an L2NW (4), uplink observation data indicating traffic volume of a session request packet addressed to an application server 2 and downlink observation data indicating traffic volume of a session response packet transmitted from the application server 2, which are acquired by observing packets input to the L2SW (5). A control unit changes shaping rate of the packets addressed to the application server (2) through the L2SW (5) included in the L2NW (4) based on a ratio between the traffic volume indicated by the uplink observation data and the traffic volume indicated by the downlink observation data, or a ratio between an increment of the traffic volume acquired from the uplink observation data and an increment of the traffic volume acquired from the downlink observation data.

  • Patent number: 11411872
    Abstract: The centralized control capability of Software Defined Networking (SDN) presents a unique opportunity for enabling Quality of Service (QoS) routing. For delay sensitive traffic flows, a QoS mechanism efficiently computes path latency and minimizes a controller's response time. At the core of the challenges is how to handle short term network state fluctuations in terms of congestion and latency while guaranteeing the end-to-end latency performance of networking services. The disclosed technology provides a systematic framework that considers active link latency measurements, efficient statistic estimate of network states, and fast adaptive path computation. The disclosed technology can be implemented, for example, as an SDN controller application, and can find optimal end-to-end paths with minimum latency and significantly reduce the control overhead.
