Abstract: Call spoofing in a Voice over Internet Protocol (IP) system may be detected and/or prevented. A device may receive a call request to initiate a VoIP call. The device may analyze marker information in the call request to determine whether the call request is valid. The device may also analyze the call request, based on call pattern information of a quantity of other calls, to determine whether the call request is suspicious; and complete the call based on the determination of whether the call request is valid and the determination of whether the call request is suspicious.

Abstract: A router policy server may include a policy engine. The policy engine may receive, from a first router, a request for whether to accept or reject routing information received from a second router and determine whether a policy, associated with the second router, allows the second router to advertise the routing information. The policy engine may further instruct the first router to accept the routing information when the policy allows the second router to advertise the routing information and may instruct the first router to reject the routing information when the policy does not allow the second router to advertise the routing information or when no policy exists for the second router in association with the policy engine.

Abstract: A method for providing security measures on a network device, such as a router, is disclosed. In one embodiment, a method includes receiving a request for a network resource. The method further includes determining a classification of the request, and generating, based on the determined classification of the request, a security measure corresponding to the determined classification of the request for authentication of the request. The method also includes permitting access to the network resource when a correct response is received to the security measure corresponding to the determined classification of the request.

Abstract: An approach provides micro-facilities for network recovery. An outage condition is detected, and is associated with one of a plurality of service provider facilities forming a service provider network. A router of the service provider network is determined to be capable of reaching the one service provider facility, wherein the provider router is resident within a customer facility. Bandwidth is allocated to one or more links for re-directing traffic over the provider router to the one service provider facility.

Abstract: A method may include forwarding, by a mobile device, a request for identification information associated with a user of the mobile device. The method may also include receiving, from an identification provider, the identification information, and displaying, by the mobile device, at least some of the identification information.

Abstract: A network device may receive a packet, determine whether the packet includes two or more headers of a same type, modify the packet to correct for the two or more headers of the same type when the packet includes the two or more headers of the same type, determine whether the packet includes out-of-sequence headers, and modify the packet to correct for the out-of-sequence headers when the packet includes the out-of-sequence headers.

Abstract: A device receives subscriber information associated with user devices provided in a network, receives network information associated with the network, and receives user device information associated with the user devices. The device also determines content to cache based on the received information, and requests the determined content from a content provider device. The device further receives the determined content from the content provider device, and stores the determined content in a cache device.

Abstract: A security card may include a printed portion that includes printed data fixed to a first portion of an outer surface of the card, an interface configured to receive digitally signed information from an external device, and a display located on a second portion of the outer surface of the card and configured to display a digital image based on the received digitally signed information.

Abstract: A method performed by a device may include exchanging encryption information with a security card, generating validation information based on the exchanged encryption information with the security card and transmitting the validation information to the security card for display.

Abstract: A security card may include a printed portion that includes printed data fixed to a first portion of an outer surface of the card, an interface configured to receive digitally signed information from an external device, and a display located on a second portion of the outer surface of the card and configured to display a digital image based on the received digitally signed information.
