  • Extensible attribute summarization
    Patent number: 9235447
    Abstract: In one embodiment a method includes at first a network device, identifying an attribute of the first network device, selecting a function that defines how the attribute is to be summarized together with a same attribute of a second network device, generating a message that comprises a set of information comprising an identification of the attribute and the function, and sending the message to, e.g., a next higher node in a network hierarchy of which the network device is a part. Multiple such messages may be received at an aggregation node that then summarizes the attributes according to respective functions, and sends or publishes a summarized version of the attributes to a still next higher node in the network hierarchy.
