Patent number: 11943126Abstract: Using a traffic monitoring service to detect traffic pattern shifts can include obtaining netflow data and routing data for core routers. Based on the netflow data and the routing data, an augmented traffic matrix can be generated. A router-level analysis can be performed on the augmented traffic matrix to identify a pair of core routers that are associated with a traffic pattern shift in the network. An entity-level analysis can be performed on the pair of core routers to identify an entity that is responsible for the traffic pattern shift in the network. Traffic shift data that identifies the pair of core routers and the entity that is responsible for the traffic pattern shift in the network can be output.Type: GrantFiled: October 26, 2022Date of Patent: March 26, 2024Assignee: AT&T Intellectual Property I, L.P.Inventors: Carlos Oliveira, Harpreet Ahluwalia, Tzuu-Yi Wang

Publication number: 20220038374Abstract: Systems, methods, and apparatuses provide a scalable framework for analyzing queuing and transient congestion in network switches. The system reports which flows contributed to the queue buildup and enables direct per-packet action in the data plane to prevent transient congestion. The system may be configured to analyze queuing in legacy network switches.Type: ApplicationFiled: October 14, 2021Publication date: February 3, 2022Inventors: Yaron Koral, Simon Tse, Steven A. Monetti, Tzuu-Yi Wang, Jennifer L. Rexford, Xiaoqi Chen, Shir Landau Feibish

Publication number: 20220007234Abstract: The technologies described herein are generally directed to centralized management of wireless relay node equipment in a fifth generation (5G) or other next generation networks. In accordance with one or more embodiments, a method described herein can include facilitating identifying a connection between first network equipment and second network equipment, the first network equipment being connected to a user equipment and the second network equipment. In embodiments, the method can further include facilitating monitoring the connection between the first network equipment and the second network equipment, resulting in monitoring data, wherein the second network equipment is communicatively coupled to backhaul network equipment, and with the user equipment being communicatively coupled to the backhaul network equipment via the second network equipment. Further, based on the monitoring data, adjusting, by the centralized controller system, a characteristic of the connection, in accordance with embodiments.Type: ApplicationFiled: March 9, 2021Publication date: January 6, 2022Inventors: Kartik Pandit, Shweta Vachhani, Tzuu-Yi Wang, Steven A.

Patent number: 11025519Abstract: Methods, systems, and computer-readable media for measuring packet delays are provided. An input port of a network device is tapped to duplicate an input packet stream having a first packet. An output port of the network device is tapped to duplicate an output packet stream including the first packet. The duplicated input packet stream and the duplicated output packet stream is transmitted to a programmable device. The first packet in the first input packet stream is matched to the first packet in the first output packet stream. An arrival time and a departure time for the first packet is measured. The difference between the departure time of the first packet and the arrival time of the first packet is determined and the value is reported to an external collector.Type: GrantFiled: April 10, 2019Date of Patent: June 1, 2021Assignees: AT&T Intellectual Property I, L.P., The Trustees Of Princeton UniversityInventors: Yaron Koral, Tuan Duong, Steven A.
