Capturing an installation of a network device provides a user with critical information that otherwise would be lost after an installation is completed. An installation audit trail system provides an accurate, reliable, secure, and immutable audit trail associated with a network device. The installation audit trail system can capture one or more input interfaces, one or more inputs associated with the one or more input interfaces, or both as one or more configuration parameters provided during the installation of a network device. The audit trail can be associated with a network device, an authenticated user, or both so as to provide historical information as well as provide security and immutability of the audit trail. The audit trail can be stored, for example, encrypted, at a repository. Associating the audit trail with a user can maintain a chain-of-custody for the audit trail.

A METHOD FOR MONITORING USAGE AND OUTGOING TRAFFIC OF AT LEAST ONE APPLICATION EXECUTED WITHIN AN OPERATING SYSTEM OF AN ELECTRONIC DEVICE
Gathering customer information from the field is crucial for operators to be proactive and enhance customer experience. More particularly, it is of interest for an operator or for a multimedia content provider to collect information regarding the use of streaming applications executed on an electronic device. Some operating systems provide means for obtaining some information regarding applications usage. However, information obtained is usually fragmented and limited. However, it is not possible based on this monitoring to determine wheter or not the multimedia content being played is provided by an authorized content provider, making it difficult to disrupt unauthorized content providers. The proposed technique is directed towards determining whether or not a multimedia content is provided by an unauthorized content provider, and implementing counter-measures against such an unauthorized content provider based on information collected during the monitoring the applications.

MULTI-MODAL APPROACH TO A SECURE AND CLOSED SOLUTION FOR PROVIDING INTELLIGENT NOTIFICATIONS
An intelligent notification system provides an intelligent notification to a client device associated with a user so as to improve the quality of service to a user. Rather than send a user monotonous or routine reminders that do not reflect current or timely information, the intelligent notification is based on user data associated with the user. By aggregating user data associated with a schedule of the user, the intelligent notification system can generate an intelligent notification that provides information to the user that is useful and pertinent. For example, a user may have already completed a regularly schedule and as such no reminder is necessary. The intelligent notification can, in lieu of a reminder, send the user an encouraging or informative intelligent reminder. In this way, a user is not inundated with stale reminders but rather receives accurate, relevant and informative intelligent notifications.
The present disclosure relates to a method for configuring an IPv6 address, a medium, a program product, and a gateway device. The method includes: determining, by a gateway device, whether a source address of a router advertisement (RA) message is the same as a link local address on a local area network (LAN) side of a gateway device, wherein both a network address translation (NAT) client and a non-NAT client are connected to the gateway device, wherein the gateway device enables the NAT client to communicate with an external network through network address translation, and wherein the gateway device does not provide network address translation for the non-NAT client to communicate with an external network; and in response to determining that the source address of the RA message is different from the link local address on the LAN side of the gateway device, sending, by the gateway device, the RA message to the non-NAT client to cause the non-NAT client to configure its IPv6 address according to the RA message. Through the above technical solution, the non-NAT client connected to the gateway device together with the NAT client can operate under IPv6, thereby enhancing network connectivity and improving communication performance.

These solutions usually look at certain types of known problems and try to detect if that problem exists in the end- user's network, and from that they conclude that the end-user might be impacted. The method according to an embodiment of the invention enables to proactively identify that an end-user is actually experiencing an event impacting the Qo E in his home network. The proposed solution enables the detection of event affecting an end-user's network, regardless of the type of the network and without looking for specific issues. This knowledge may be a valuable asset of an Internet Service Provider which may fix issues quicker or mitigate end-users' dissatisfaction.
