  • Communications methods and apparatus for minimizing and/or preventing message processing faults
    Patent number: 12009967
    Abstract: The present invention relates to methods and apparatus for detecting, minimizing and/or preventing message processing faults and in particular message processing fault avalanches at a single processing device and among a cluster of message processing devices. An exemplary method embodiment includes: enabling message blocking at a Session Border Controller (SBC) for Session Initiation Protocol (SIP) messages including a first key value in response to a first threshold number of SIP messages including the first key value having caused a SIP message processing failure; receiving, at the SBC, a SIP message including at least one key value; determining if message blocking is enabled for one or more key values included in the SIP message; and dropping by the SBC the SIP message in response to determining that message blocking is enabled for one or more key values included in the SIP message, but otherwise processing the SIP message by the SBC.
