Abstract: A cloud gateway outage risk detector can receive, by an event listener module, user session data associated with a plurality of user sessions over a cloud gateway. The event listener module can store the data in a database. A run-time collection module can obtain at least a portion of the data. The run-time collection module can provide the portion of the data to a run-time risk criteria evaluation module that can determine, based upon the portion of the data, a run-time outage risk criteria for the cloud gateway. A baseline risk criteria evaluation module can obtain historical data from the database. The baseline risk criteria evaluation module can determine, based upon the data, a baseline outage risk criteria for the cloud gateway. The run-time risk criteria evaluation module can determine whether the run-time outage risk criteria meets or exceeds an outage risk threshold.

Abstract: Concepts and technologies directed to network fault originator identification for virtual network infrastructure are disclosed herein. Embodiments can include a control system that is communicatively coupled with network infrastructure. The control system can include a processor and memory that, upon execution, causes the control system to perform operations. The operations can include determining, based on a source ticket, a network fault condition associated with the network infrastructure. The operations can further include identifying, from the source ticket, a trap set and an alarm set that are associated with origination of the network fault condition. The operations can include the control system collecting network event data from the network infrastructure prior to a polling time of a fault reporting schedule; determining that a qualified source ticket should be created; and generating the qualified source ticket based on the network event data.

Abstract: A system can collect, from an address resolution protocol (“ARP”) cache of a managed virtual network function (“VNF”), at least one active entry corresponding to at least one active element of a plurality of virtual local area network (“VLAN”) networks. The system can check the ARP cache for an entry associated with at least one of the plurality of VLAN elements. The system can determine whether an entry associated with at least one of the plurality of VLAN elements was found. In response to determining that an entry associated with at least one of the plurality of VLAN elements was not found, the system can send an ARP request to the plurality of VLAN elements, wait for an ARP response, and, in response to determining that an ARP response has not been received, generate a notification that VLAN connectivity has been lost.
