20130215754 | Servers, Switches, and Systems with Switching Module Implementing a Distributed Network Operating System - One networking device includes a switch module, a server, and a switch controller. The switch module has ports with a communications interface of a first type (CI1) and ports with a communications interface of a second type (CI2). The server, coupled to the switch module via a first CI2 coupling, includes a virtual CI1 driver, which provides a CI1 interface in the server, defined to exchange CI1 packets with the switch module via the first CI2 coupling. The virtual CI1 driver includes a first network device operating system (ndOS) program. The switch controller, in communication with the switch module via a second CI2 coupling, includes a second ndOS program controlling, in the switch module, a packet switching policy defining the switching of packets through the switch module or switch controller. The first and second ndOS programs exchange control messages to maintain a network policy for the switch fabric. | 08-22-2013 |
20130223438 | Methods and Systems for Managing Distributed Media Access Control Address Tables - Methods, systems, and computer programs are presented for switching a network packet. One method includes operations for receiving a packet having a media access control (MAC) address, and for switching the packet by a first packet switching device (PSD) when the MAC address is present in a first memory. Further, the method includes operations for transferring the packet to a second PSD when the MAC address is absent from the first memory and present in a second memory associated with the second PSD, and for transferring the packet to a third PSD when the MAC address is absent from the first memory and the second memory. | 08-29-2013 |
20130235870 | Methods, Systems, and Fabrics Implementing a Distributed Network Operating System - Methods, systems, and computer programs are presented for managing a switching layer fabric. A network device operating system (ndOS) program includes program instructions for exchanging switching policy regarding a switching of network packets in a plurality of ndOS switching devices having respective ndOS programs executing therein. The first ndOS program is executed in a first ndOS switching device, and the switching policy is exchanged with other ndOS programs via multicast messages. Further, the ndOS program includes program instructions for exchanging resource control messages with the other ndOS switching devices to implement service level agreements in the switching layer fabric, where the ndOS switching devices cooperate to enforce the service level agreements. Further yet, the ndOS program includes program instructions for receiving changes to the switching policy, and program instructions for propagating the received changes to the switching policy via message exchange between the ndOS programs. The ndOS switching devices are managed as a single logical switch that spans the plurality of ndOS switching devices. | 09-12-2013 |
20130238885 | Network Switch, Systems, and Servers Implementing Boot Image Delivery - Methods, systems, and computer programs are presented for providing a program to a server. One method includes an operation for receiving a request by a switching device from a first server, the request being for a boot image for booting the first server. In addition, the method includes operations for determining if the boot image is available from non-volatile storage in the switching device, and for forwarding the request to a second server when the boot image is absent from the non-volatile storage. Further, the method includes an operation for sending the boot image to the first server from the switching device when the boot image is available from the non-volatile storage. | 09-12-2013 |
20130242983 | Servers, Switches, and Systems with Virtual Interface to External Network Connecting Hardware and Integrated Networking Driver - 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. | 09-19-2013 |
20150071292 | METHOD AND SYSTEM FOR PROCESSING PACKETS IN A NETWORK DEVICE - Systems are presented for processing packets in a network switch. One network device includes a processor, an Ethernet switch, a PCIe switch, and a packet processor. The processor is for executing a controller program, and the Ethernet switch is for switching packets among a ports. Further, the PCIe switch is coupled to the processor and the Ethernet switch, and the packet processor, coupled to the Ethernet switch and the PCIe switch, is operable to modify an application header of an incoming packet and send the incoming packet to one of the ports. The controller program is operable to configure the Ethernet switch and the packet processor to define processing of packets. The controller program is operable to send a first configuration rule to the Ethernet switch, the first configuration rule defining that packets of a network flow requiring header modification be forwarded to the packet processor. | 03-12-2015 |

20110314473 | SYSTEM AND METHOD FOR GROUPING MULTIPLE PROCESSORS - A distributed multi-processor out-of-order system includes multiple processors, an arbiter, a data dispatcher, a memory controller, a storage unit, multiple memory access requests issued by the multiple processors, and multiple data units that provide the results of the multiple memory access requests. Each of the multiple memory access requests includes a tag that identifies the priority of the processor that issued the memory access request, a processor identification number that identifies the processor that issued the request, and a processor access sequence number that identifies the order that the particular one of the processors issued the request. Each of the data units also includes a tag that specifics the processor identification number, the processor access sequence number, and a data sequence number that identifies the order of the data units satisfying the corresponding one of the memory requests. Using the tags, a distributed arbiter and data dispatcher can execute the requests out-of-order, handle simultaneous memory requests, order the memory requests based on, for example, the priority, return the data units to the processor that requested it, and reassemble the data units. | 12-22-2011 |
