Scott S. McDaniel - Villa Park CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03M 13/09

US Classification:

714776

Abstract:

Systems and methods that protect heading information using a dedicated cyclic redundancy check (CRC) are provided. In one embodiment, a method that transmits a data packet may include, for example, one or more of the following: creating a header CRC by performing a CRC process on header information, the header information indicating where to place data information; separately creating a data CRC by performing the CRC process on the data information; and forming a data packet including, for example, the header information, the header CRC, the data information and the data CRC.

Abstract:

Aspects of the invention may provide TCP offload, which may include acquiring TCP connection variables from a host and managing at least one TCP connection using the acquired TCP connection variables. At least a portion of the acquired TCP connection variables may be updated and at least some of the updated TCP connection variables may be transferred back to the host. In an aspect of the invention, the TCP connection variables may be variables that are independent of bandwidth delay product. At least a portion of the updated TCP connection variables may be utilized by the host to process the TCP connection or another TCP connection. The host may push the variables onto the stack and the TOE may pull the variables from the stack. Also, updated TCP connection variables may be pushed on the stack by the TOE and pulled from the stack by the host.

G06F 15/16
H04L 12/56

US Classification:

709232, 709236, 370419

Abstract:

Aspects of the invention may comprise receiving an incoming TCP packet at a TEEC and processing at least a portion of the incoming packet once by the TEEC without having to do any reassembly and/or retransmission by the TEEC. At least a portion of the incoming TCP packet may be buffered in at least one internal elastic buffer of the TEEC. The internal elastic buffer may comprise a receive internal elastic buffer and/or a transmit internal elastic buffer. Accordingly, at least a portion of the incoming TCP packet may be buffered in the receive internal elastic buffer. At least a portion of the processed incoming packet may be placed in a portion of a host memory for processing by a host processor or CPU. Furthermore, at least a portion of the processed incoming TCP packet may be DMA transferred to a portion of the host memory.

Broadcom Corporation - Irvine CA

International Classification:

H04L 12/66

US Classification:

370463, 370419

Abstract:

Systems and methods that interface with a management system are provided. In one embodiment, a system and a method may provide a command protocol and format for communication between a network interface card (NIC) and a management device such as, for example, an intelligent management device (IMD). An interface may be adapted to allow the management device to merge its traffic with that of the NIC to provide a fully integrated management solution. The fully integrated management solution may be implemented, for example, without additional network connections.

US Classification:

709250

Abstract:

Systems and methods that handle frames in multiple stack environments are provided. In one embodiment, a system may include, for example, a non-offload protocol stack and an offload protocol stack, the offload protocol stack being coupled to the non-offload protocol stack. The non-offload protocol stack may include, for example, one or more partially processed frames. The one or more partially processed frames may be sent to the offload protocol stack to complete processing in the offload protocol stack.

Abstract:

Methods and apparatus for providing a bus interface are disclosed. An example method for providing a bus interface includes operating first circuitry using a first power supply voltage in a normal operating mode, where the first circuitry includes at least a portion of datapath circuitry of the bus interface. The example method further includes powering down the first circuitry in a low power operating mode and operating second circuitry using the first power supply voltage in the normal operating mode. The example method also includes operating the second circuitry using a second power supply voltage in the low power operating mode. The second circuitry includes a power management control circuit adapted to receive a power management event indication signal. Responsive to the power management event indication signal, the control circuit provides at least one of an in-band power management indication and an out-of-band power management indication to one or more devices in a computing system. In the example method, the first and second power supply voltages may be provided by a single power supply or, alternatively, by multiple power supplies.

Abstract:

Certain aspects of a method and system for interlocking data integrity for network adapters are disclosed. Aspects of one method may include executing a plurality of interlocking checks within a network adapter. Each interlocking check may comprise receiving a plurality of input check values associated with a plurality of input data packets corresponding to a first protocol. A plurality of check values may be generated which are associated with the plurality of input data packets and a plurality of output data packets corresponding to a second protocol. The data integrity of the plurality of input data packets and the plurality of output data packets may be validated based on one or more comparisons between one or more of the generated plurality of check values and one or more of the received plurality of input check values.
