  • Patent number: 9871765
    Abstract: Various exemplary embodiments relate to a method performed by a DIAMETER network node, the method including: receiving a first DIAMETER message; determining that the first DIAMETER message is not trusted; and rejecting the first DIAMETER message.
    Type: Grant
    Filed: September 4, 2012
    Date of Patent: January 16, 2018
    Assignee: Alcatel Lucent

  • Patent number: 9602382
    Abstract: A method for dynamic reaction to DIAMETER routing failures is disclosed. The method for dynamic reaction to DIAMETER routing failures includes receiving a DIAMETER message, calculating a statistic associated with the route of the message, testing if the message is an unable_to_deliver message type, and if it is, testing the calculated statistic against a criterion. In the event the statistic exceeds the criterion, an action pertinent to the route which had a delivery failure is taken. The method for dynamic reaction to DIAMETER routing failures provides for dynamic management of routes at the node level in response to delivery failures. The method for dynamic reaction to DIAMETER routing failures is particularly useful for overcoming bandwidth usage in terms of delivery failures known in the art.

  • Patent number: 8964529
    Abstract: Various exemplary embodiments relate to a method performed by a network node, the method including: receiving a connection request from a peer network node including a peer identifier; determining that the received peer identifier matches an identifier of an existing peer; sending a verification message to the existing peer; setting a timer; when a response the verification message is received before the timer expires: cancelling the timer; and rejecting the received connection request; when the timer expires: closing a connection to the existing peer; and accepting the new connection from the new peer.

  • Patent number: 8787382
    Abstract: A method for per-peer request delivery timeouts includes receiving a DIAMETER message at a DIAMETER Routing Agent, testing if the DIAMETER message is a request message destined for an associated peer, and if said test is affirmative, then retrieving a preset timeout associated with that peer; initiating a timeout timer with said preset timeout; and forwarding the DIAMETER request message to said peer. The disclosure provides additional steps with respect to stopping the timer in the event that a response message is received prior to the timer expiring; or alternatively, either resending the request or providing an unable_to_deliver response in the event the timer does expire. The method for per-peer request delivery timeouts provides for fine tuning timeout periods according to the networks to which the DIAMETER peers are connected. The method is particularly useful for reducing the amount of time waiting for response messages which will not be forthcoming.
