Abstract: Wireless networks may have thousands of configurable parameters, so manual tuning is infeasible. A self-organizing network (SON) can provide automation. However, automated algorithms are not designed to interact with a wireless network, and network experimentation can jeopardize reliability. To address the former, a SON facilitator of a wireless network management node exposes an API that can translate network configuration information for consumption by a SON enhancer, which may implement an AI algorithm for network tuning. The SON facilitator can also transform output from the SON enhancer into directions for controlling a test scenario, including generating a DL SON message describing the test to a UE. To further increase reliability during the test scenario, the UE can be provisioned with two wireless connections. A first connection is unchanged by the test scenario for stability, and a second connection is used for testing.

Abstract: Devices with low or no security are often added to networks. These devices have the ability to utilize the network and, accordingly, may pose a security risk. Systems and methods herein enable a device to be added to a network and, if the resulting new traffic matches a template, the device is established on an automatically created virtual local area network (VLAN) used solely for the new device. A router is automatically configured to allow traffic that matches the type of device that was newly added, but if other traffic is detected, the device may be treated as a threat and managed accordingly.

Abstract: Renewably-sourced biodegradable polyolefin packaging, utensils, and containers include a renewably-sourced polyolefin (for example, polyethylene and polypropylene) and a biodegrading agent. The renewably-sourced biodegradable polyolefin packaging is made from plant materials typically by polymerizing olefins that are made from reducing alcohols created by fermenting plant materials. An example of a suitable plant material is sugarcane and its derivatives. The biodegrading agent accelerates the biodegradation of polyolefin packaging even in anaerobic and dark (i.e., absent of ultraviolet light) environments. Such a packaging is particularly useful for packaging frozen food that is to be microwaved in the packaging. The package is also particularly usable as packaging for frozen comestibles, which are often stored at dry-ice temperatures.
