Aspects are described that utilize a distributed network of measurement points to detect sources of lag in a network, but are not so limited. Sources of lag can be detected at particular locations in a network or multiple networks using a plurality of distributed measurement points. Each measurement point can be configured to monitor network conditions at a particular network location using a measurement client to perform a network testing procedure with a measurement stream. Each measurement point can also include a measurement server configured to receive a measurement stream from at least one measurement client. A controller is configured to manage and control one or more of the plurality of measurement clients using a secure connection. Aspects are configured to detect one or more sources of lag of a distributed network of devices and/or cause procedures to be implemented to mitigate identified sources of lag.

Identifying and mitigating sources of lag in a network

Aspects of the present disclosure provide for the detection and/or use of countermeasures to prevent and/or limit unauthorized devices from accessing and/or using another's communication network. An exemplary system includes a cloud controller and a gateway device that communicate via the infrastructure provided by a service provider communication network, wherein the gateway device operates in part to execute a device discovery algorithm to detect devices that are connected to a network facilitated by the gateway device and/or employ countermeasures to thwart further access by any unauthorized device. An exemplary method executes a device discovery algorithm to apply one or more of a plurality of device discovery protocols to detect devices that are connected to a network facilitated by a gateway device and/or implement countermeasures to block further access. Other aspects are described in detail herein.

System to detect and/or prevent unauthorized access to a communication network

A secure connection to a router web UI is provided. In one implementation, responsive to a client request to securely connect to a router web server (RWS), the RWS generates and sends a certificate signing request (CSR) to a remote-security certificate server (R-SCS). Upon validation of the RWS, the R-SCS signs and transmits a router web UI certificate (RWUIC) to the RWS to present to the client. In another implementation, the router includes a local-SCS (L-SCS) that periodically obtains a short-lived intermediate certification authority (ICA) certificate from the R-SCS. Responsive to a client request for secure access to the RWS, the RWS generates and sends a CSR to the L-SCS for the RWUIC. The L-SCS signs the RWUIC and passes the ICA certificate and RWUIC to the RWS, which presents the certificate(s) to the client. Upon validation of the certificate(s), a secure channel between the client and RWS is established.
