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.

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.

Abstract: In one example, the present disclosure describes a device, computer-readable medium, and method for providing estimated bandwidth ranges to network-attached entities such as applications, user endpoint devices, and customer premises equipment. For instance, in one example, a method performed by a processing system including at least one processor includes collecting performance data for a communications network from a plurality of sensors distributed throughout the communications network, calculating based on the performance data, an estimated lower limit of an available bandwidth in the communications network and an estimated upper limit of the available bandwidth in the communications network, receiving a query from a network attached entity for the available bandwidth in the communications network, and providing, in response to the query, the estimated lower limit and the estimated upper limit to the network attached entity.

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; determining, at the control plane, a distributed firewall for a first firewall in the network to enforce the network traffic rule; instructing, using the control plane, a first software-defined networking node to instantiate the first firewall of the distributed firewall; configuring a second software-defined networking node to route network traffic through the first firewall; and instructing the first software-defined networking node to enforce the network traffic rule.

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.

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.
