摘要： 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.

摘要： 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.

摘要： Methods, systems, and computer programs are presented for managing network switching. A network device operating system (ndOS) program includes instructions for exchanging switching policy regarding switching network packets in a plurality of ndOS devices having ndOS programs. The first ndOS program is executed in a first ndOS device, and the switching policy is exchanged with other ndOS programs via multicast messages. Further, the ndOS program includes instructions for exchanging resource control messages with the other ndOS devices to implement service level agreements in the switching fabric, where the ndOS switching devices cooperate to enforce the service level agreements. Further yet, the ndOS program includes instructions for receiving changes to the switching policy, and instructions for propagating the received changes to the switching policy via message exchange between the ndOS programs. The ndOS devices are managed as a single logical switch that spans the plurality of ndOS devices.

摘要： Methods, systems, and computer programs are presented for managing a network in the presence of layer-2 loops. One method includes an operation for detecting, by a network device, a loop at a layer 2 of a network. The network device is configured to execute a network device operation system (ndOS), where network devices executing ndOS share a global switch table. The method further includes an operation for blocking ports associated with the loop where incoming packets received at the blocked ports are discarded except for loop-probe packets. Further, the method includes operations for sending loop-probe packets by one or more network devices executing ndOS through one or more ports, and for unblocking a first port of the blocked ports based on the loop-probe packets when a lack of receipt of a loop-probe packet within a predetermined amount of time is detected for the first blocked port which indicates that the first blocked port is not part of the loop.

摘要： 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.
