Abstract: Systems and methods for data path retention during control plane failures in a Multiprotocol Label Switching (MPLS) network include, in a network element, operating an MPLS service on a data path in the MPLS network in an initial stage with both a control plane and a data plane operating normally; responsive to a failure affecting only the control plane, switching the MPLS service to an Ethernet Line (ELINE) service which is configured on the data path; and, responsive to a recovery of the control plane, switching the ELINE service back to the MPLS service.

Abstract: To detect an attack of a network connection, detection of a message containing a sequence number that is within a valid sequence number range is performed, where the message is intended to cause reset of the network connection. The message is dropped, and a counter is incremented to track a number of occurrences of receiving the message in response to detecting that the sequence number in the message is within the valid sequence number range.

Abstract: In accordance with one or more aspects of the electronic coupon tracking, a record of an electronic coupon that has been distributed to a user is maintained. An indication that the electronic coupon has been redeemed at a retailer via a mobile device is received, and redemption of the electronic is recorded. Additionally, an indication can be received that the electronic coupon has been redeemed by the user. In response to receipt of this indication, a rewards account corresponding to the user is credited with one or more points.
