  • Publication number: 20240089750
    Abstract: An architecture related to notifying user equipment of communication transportation functionality and/or facility shifts between a wired communication transportation framework and a wireless communication transportation framework. A method can comprise determining a decrease in a number of data packets flowing through a wireline network interface over a defined period of time, based on the number of data packets, determining that the wireline network interface is failing, generating a notification comprising a data record comprising a field representing a state associated with the failing wireline network interface, and sending the notification to a user equipment.

  • Publication number: 20230254283
    Abstract: Distributed firewalls in a network are disclosed. Example firewall controllers disclosed herein are to instruct a first network node of a software-defined network to implement a first firewall instance of a distributed firewall, the first network node to implement the first firewall instance with a first virtual machine. Disclosed example firewall controllers are also to configure a second network node of the software-defined network to route network traffic through the first firewall instance and, after at least some of the network traffic is dropped by the first firewall instance, instruct the second network node to implement a second firewall instance of the distributed firewall, the second network node to implement the second firewall instance with a second virtual machine.

  • Publication number: 20230179469
    Abstract: Architectures and techniques are presented that provide an improved mechanism for a subscriber entity to report to a network provider a network issue that affects the performance of an application that uses a service provided by the network provider. The improved mechanism can enable fine granularity with respect to the network issue by identifying the issue on a per-session basis. In response to feedback data that is reported by the subscriber entity, the network provider can perform self-healing or other upgrade techniques to rapidly remedy the network issue.

  • Publication number: 20220385552
    Abstract: Architectures and techniques are presented that record bi-directional traffic flows of a network such as a software defined network, that result from execution of a specified application. This recorded traffic data can be generated prior to a network change and can be anonymized in various ways to maintain security and privacy. After applying the network change, the traffic data can be replayed to test performance of the specified application in a manner that realistically represents actual use of the specified application.

  • Publication number: 20220337336
    Abstract: Maximizing throughput on a variable bandwidth communication interface is presented herein. A first device, based on information that was received from a second device via a communication link communicatively coupling the first device to the second device, determines a rate of change of data packet loss of first data packets that have been transmitted, based on a first data transmission rate via the communication link, from the first device to the second device; and in response to the rate of change of data packet loss being determined to satisfy a defined condition that is based on a defined state of a group of defined states corresponding to respective data transmission rates comprising the first data transmission rate, modifies the first data transmission rate to obtain a second data transmission rate, and transmits, based on the second data transmission rate, second data packets to the second device.

  • Patent number: 10623373
    Abstract: Methods and apparatus to provide a distributed firewall in a network are disclosed. An example method includes identifying, at a control plane, a network traffic rule to implement in a network, and determining a first firewall of a distributed firewall in the network to enforce the network traffic rule. Example methods also configure a first software-defined network node to route network traffic to the first firewall. The first firewall is instantiated by a first firewall instance at a second software-defined network node and by a second firewall instance at a third software-defined network node. In response to determining at least some of the network traffic forwarded by the first software-defined network node to the second and third software-defined network nodes is being dropped at the first and second firewall instances, example methods also cause the first software-defined network node to implement a third firewall instance.
