  • Publication number: 20190273653
    Abstract: A software-defined network controller (SDN controller) defines a first network flow to be selectively implemented by a networking device according to a first network operation profile. The SDN controller defines a second network flow to be selectively implemented by the networking device according to a second network operation profile. A memory device of the networking device may store at least first and second network operation profiles for selective implementation based on network packet characteristic matching and/or a “trigger alarm” event. The first network operation profile is implemented when an incoming network packet matches a pre-defined and/or customizable network packet characteristic match template. The second network operation profile is implemented when a “trigger alarm” event is received. A network operation profile may execute a write action to latch, or otherwise trigger, a physical alarm of a networking device or associated device.

  • Publication number: 20190273717
    Abstract: The present disclosure pertains to systems and methods of monitoring communication devices and communication links in a software-defined network (SDN). Network packets may be colored or tagged for routing to a packet analyzer. A VLAN bitmask may be added to a packet to identify the packet for inspection and, optionally, provide origin information identify a switch and/or port of origin. Port mirroring may be utilized and/or eventual routing of network packets to their original destination may ensure that network traffic is not disrupted. In one example, a most significant bit of a VLAN bitmask may be used by a match rule to identify packets intended for a packet analyzer without regard to original packet routing instructions and/or packet content.

  • Publication number: 20190173754
    Abstract: A software-defined network controller (SDN controller) defines a first network flow to be selectively implemented by a networking device according to a first network operation profile. The SDN controller defines a second network flow to be selectively implemented by the networking device according to a second network operation profile. The first and second network operation profiles are stored within a memory of the networking device to be selectively implemented based on the status of a profile selection input on the networking device. The profile selection input is a contact input in some embodiments. When the contact input is de-asserted, the networking device implements the first network flow according to the first network operation profile. When the contact input is asserted, the networking device implements the second network flow according to the second network operation profile.
