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： 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.
