    Abstract: Disclosed herein are methods of forwarding packets on a network, such as a leaf-spine network having leaf devices and spine devices. The methods may include receiving a packet at an ingress leaf device, and determining based, at least in part, on a header of the packet whether the packet is to be transmitted to a spine device. The methods may further include ascertaining based, at least in part, on a header of the packet whether to perform encapsulation on the packet, encapsulating the packet according to a result of the ascertaining, and then transmitting the packet to a spine device according to a result of the determining. Also disclosed herein are network apparatuses which include a processor and a memory, at least one of the processor or the memory being configured to perform some or all of the foregoing described methods.

    IPC: H04L12/26

    Abstract: Disclosed is a method for continuous in-line monitoring of data-centric traffic to guarantee application performance. The method includes, in each switch of a plurality of switches in a network fabric, grouping all packets entering each respective switch of the plurality of switches based on either 5-tuple applications or EPG based applications, collecting performance statistics at every hop in the network fabric across all flows in-line in a flow table maintained in each respective switch and periodically exporting the performance statistics to analysis module.

    Abstract: Systems, methods and computer-readable storage devices each provide, for a given flow entry in a flow table associated with a packet flow, a first atomic counter associated with a first color and a second atomic counter associated with a second color. The system, for a first coloring interval, marks traffic in the packet flow from a tenant to a fabric as the first color and increments the first atomic counter. At a conclusion of the first coloring interval and for a second coloring interval, the system marks the traffic in the packet flow from the tenant to the fabric as the second color and increments the second atomic counter. The system compares first packet counts associated with the first color at an ingress point with second packet counts associated with the first color at an egress point to the fabric.
