Abstract: Methods, systems, and computer programs are presented for networking communications. One method includes an operation for receiving a packet in a first format by a virtual driver providing a communications interface of a first type (CI1), the first format being for CI1. Further, the method includes an operation for encapsulating the packet in a second format by a processor, the second format being for a communications interface of a second type (CI2) different from CI1. In addition, the method includes an operation for sending the encapsulated packet in the second format to a switch module. The switch module includes a switch fabric, one or more CI1 ports, and one or more CI2 ports, and the switch module transforms the packet back to the first format to send the packet in the first format to a CI1 network via one of the CI1 ports in the switch module.

Abstract: Systems, methods, and computer programs are presented for managing network traffic. A network switch includes a switch fabric and a resource coherency and analytics engine (RCAE) coupled to the switch fabric. The RCAE includes one or more virtualizable resource groups (VRGs) for managing network traffic flow across a plurality of network switches on the network. Further, the RCAE is operable to add network entities to each VRG, add flows to each VRG, and add other VRGs to each VRG. A virtualizable resource control list (VRCL), associated with each VRG, identifies which network entities in the VRG can communicate with each other, which network entities in the VRG can communicate with network entities in other VRGs, and a guaranteed bandwidth for the VRG associated with the VRCL. Furthermore, the RCAE is operable to exchange messages with other RCAEs in other network switches to implement traffic policies defined by each VRCL.

Abstract: In general, the invention relates to a network device that includes a port configured to receive a packet and a packet processor (PP) configured to receive the packet from the port, in response to receiving the packet, make a first determination that a trigger condition exists, and in response to the first determination, issue a configuration action, where the configuration action, when performed by the network device, modifies a configuration of a component on the network device.

Abstract: In general, in one aspect, the invention relates to a network device, including: an input port; an output port; a switch fabric including a primary fabric, an auxiliary fabric, and a controller; and a distributor configured to obtain, from the input port, a first data unit, provide the first data unit to the primary fabric, determine, after the first data unit is transmitted to the primary fabric, that the primary fabric is congested, send, in response to determining that the primary fabric is congested, a request to the controller to establish a data path through the auxiliary fabric, obtain, from the input port and after sending the request, a second data unit, provide the second data unit to the auxiliary fabric, where the auxiliary fabric transmits the second data unit to the aggregator through the data path in the auxiliary fabric.

Abstract: A system that includes a switch fabric and a resource coherency and analytics engine (RCAE). The RCAE includes a virtual traffic shaper (VTS). The VTS includes virtual output queues (VOQs), where each VOQ is associated with a virtualizable resource group (VRG)-OP pair. The VTS includes functionality to receive a first packet, make a first determination that the first packet is to be sent to a first OP, make a second determination that the first packet is associated with a first VRG, and store, based on the first and second determinations, the first packet in a VOQ associated with a first VRG-OP pair. The VTS also includes functionality to schedule the first packet for transmission from the VOQ to the switch fabric.
