  • Patent number: 9014013
    Abstract: Improved debugging capabilities for network packet path tracing. Embodiments trace both the control and data planes. During control plane operations each switch appends its identity to the payload, providing a full trace of the control plan path. SNMP Trap commands containing the forward path payload are provided back at each hop. The data plane is monitored by setting traps along the control plane path, with SNMP Trap commands at each hop being provided that indicate a given switch has been used.
    Type: Grant

  • Patent number: 8892717
    Abstract: A network management device which registers for any state change notifications from the devices in the network. The network management device updates its status and values of the devices associated with each state change notification by querying the device. In this manner the management device can make a more timely update for a particular device and need not keep querying devices that have not changed, thus eliminating many unnecessary transactions. In certain embodiments polling is still performed. As a result, the management device is both more current in its displayed data and has fewer network transactions.
