Abstract: Symmetric networking techniques disclosed herein can be applied by gateway routers in cloud networks. The techniques can ensure that both outbound traffic received at a cloud from a branch device and return traffic directed from the cloud back to the branch device are processed by a same gateway router. The gateway router can use network address translation to insert IP addresses from an inside pool and an outside pool assigned to the router.

Abstract: Devices, networks, systems, methods, and processes for determining receiver performance metric of a network device are described herein. A device may utilize one or more error patterns associated with the network device to retrieve one or more symbol errors from the one or more error patterns. The device can determine an error threshold for a segment based on a predefined Bit Error Rate (BER) level for the segment. The device may generate a performance metric for the segment based on the error threshold and the retrieved symbol errors. The device can generate a receiver performance metric based on performance metrics of segments. The device may determine a Code Error Ratio (CER) and can predict a Frame Loss ratio (FLR) associated with the network device based on the CER.

Abstract: Techniques, which may be embodied herein as systems, computing devices, methods, algorithms, software, code, computer readable media, or the like, are described herein for comparing a set of metrics generated during a simulated user interaction with a website to metrics generated by observing real user interactions with the website. Simulated user interactions with a website can be used to diagnose a website's performance issues, but it can be difficult to determine whether the simulated interactions reflect the experience of real users. In addition, the simulated user interactions can be challenging to contextualize because the number of observed real user interactions may significantly outnumber the simulated interactions. A graphical user interface can help with the interpretation of these website interactions by using the real user interactions to properly contextualize the simulated results.

Abstract: A network infrastructure component determines a risk measurement associated with a wireless client device's use of a device address, and provides an advisory with respect to an address rotation strategy of the wireless client device based on the risk measurement. In some embodiments, the risk measurement is based on one or more of an exposure, by the wireless client device, of information on the wireless network that identifies the wireless client device and/or a characterization of a security of the wireless network environment in which the wireless client device operates.

Abstract: Access Point ranging and placement on a floorplan may be provided. A host AP may range each neighbor AP of the host AP. One or more neighbor APs that failed ranging with the host AP may be categorized in a failed neighbor AP list. The host AP may re-range each of the one or more neighbor APs in the failed neighbor AP list with a modified ranging parameter. At least one neighbor AP of the one or more neighbor APs may be categorized in the failed neighbor AP list that succeeded in re-ranging with the host AP in an extended range neighbor AP list.
