Abstract: The same prefix segment identifier (SID) may be configured and/or used for either (A) more than one prefix within an interior gateway protocol (IGP) domain, or (B) one prefix with more than one path computation algorithm within the IGP domain by: (a) receiving, by a node in the IGP domain, an IGP advertisement including both (1) a prefix SID and a segment routing global block (SRGB) slice identifier; (b) determining whether or not the SRGB slice identified by the SRGB slice identifier is provisioned on the node; and (c) responsive to a determination that the SRGB slice identified by the SRGB slice identifier is not provisioned on the node, not processing the prefix SID included in the received IGP advertisement, and otherwise responsive to a determination that the SRGB slice identified by the SRGB slice identifier is provisioned on the node, (1) processing the prefix SID and SRGB slice to generate a unique, per SRGB slice, MPLS label for the prefix, and (2) updating a label forwarding information base (LFIB) for the node using the unique, per SRGB slice, label for the prefix and the prefix.

Abstract: Techniques are described for automatically configuring one or more settings of wireless radios within access point (AP) devices at a site based on wireless radio configuration settings for wireless radios within AP devices at manually tuned sites, i.e., “golden sites.” The techniques may automatically configure channel bandwidth settings of the wireless radios within the AP devices to optimize performance of wireless networks at the site. A system monitors operational parameters of the wireless radios within the AP devices at a site, identifies a class of wireless radios within AP devices at the golden sites that have similar operational parameters as one or more wireless radios within a particular AP device at the site, and automatically configures the settings of the wireless radios within the particular AP device at the site based on the settings associated with the identified class of wireless radios within AP devices at the golden sites.

Abstract: Methods and apparatus for processing and using signals transmitted by a device, e.g., a low cost beacon transmitter device, to facilitate making location determinations with regard to the transmitting device and/or making a decision of when or how to use location information generated based on received signals are described. In accordance with some features the processing performed on the received signal strength measurements is based on whether or not the device from which the signals are received is in motion. The size of a sample period used as a processing window when determining device location is based, in some embodiments, on the rate of motion. When and/or how to use location determinations are performed is also based on motion in some embodiments. Machine learning updates of location determination parameters, based on received signals, are disabled when the signals are from devices determined to be in motion.

Abstract: An example network system includes processing circuitry and one or more memories coupled to the processing circuitry. The one or more memories are configured to store instructions which cause the system to obtain telemetry data, the telemetry data being associated with a plurality of applications running on a plurality of hosts. The instructions cause the system to, based on the telemetry data, determine a subset of applications of the plurality of applications that run on a first host of the plurality of hosts. The instructions cause the system to determine a subset of firewall policies of a plurality of firewall polices, each of the subset of firewall policies applying to at least one respective application of the subset of applications. The instructions cause the system to generate an indication of the subset of firewall policies and send the indication to a management plane of a distributed firewall.

Abstract: The disclosure relates to computer networking and, more specifically, to service chaining a containerized network function (CNF) using a containerized router, the CNF and containerized router both deployed to the same server. In an example, a method comprises executing, with a computing device: a containerized network function; a virtual router to implement a data plane for a containerized router; and a containerized routing protocol daemon to implement a control plane for the containerized router, wherein the containerized network function and containerized routing protocol daemon execute on the same computing device, and wherein a first virtual network interface of the computing device enables communications between the containerized network function and the virtual router; and forwarding, by the virtual router, based on a static route, traffic destined for a prefix to the first virtual network interface to send the traffic to the containerized network function.
