Abstract:

An example network system includes a plurality of endpoint computing resources, a business policy graph of a network that includes a set of the plurality of endpoint computing resources configured as a security domain, a set of policy enforcement points (“PEPs”) configured to enforce network policies, and a network management module (“NMM”). The NMM is configured to receive an indication of a set of network policies to apply to the security domain, automatically determine a subset of PEPs of the set of PEPs are required to enforce the set of network policies based on physical network topology information readable by the NMM that includes information about the location of the endpoint computing resources and the set of PEPs within the network, and apply the network policies to the subset of PEPs in order to enforce the network policies against the set of endpoint computing resources of the security domain.

Appl. No.:

09/760686

Inventors:

Sanjay Agarwal - Santa Clara CA, US

International Classification:

G06F001/26
G06F001/28
G06F001/30

US Classification:

713/324000

Abstract:

A method for power management and energy conservation in computer networking equipment uses the information on network traffic intensity. The cooling and ventilation provided is directly proportional to network traffic intensity. The traffic intensity information is conveyed to the power management processor, which uses pulse width modulation (PWM) to control cooling and ventilation fans in the equipment. Traffic intensity is proportional to the switching activity in integrated circuits. Switching activity in integrated circuits is proportional to the heat generation in integrated circuits. Higher traffic intensity results in higher heat generation, which correspondingly results in higher cooling and ventilation requirements. The cooling and ventilation should adapt dynamically to the requirements of the system. This adaptation and optimal application of cooling and ventilation in networking equipment provides reduction in power usage in the system equipment. The function of power management processor can be outside of the existing integrated circuits electronics or alternatively can be designed within one of the existing integrated circuits. Control of cooling and ventilation system will also provide reduction in noise levels within the networking equipment facility. This power management invention can also be applied to Storage Area Network (SAN) networking equipment and wireless networking equipment, which is part of the network computing system. The invention can also be deployed in a heterogeneous network comprising of a combination of wired networking, storage area network, and wireless network.

International Classification:

US Classification:

712/035000, 712/221000

Abstract:

A method for implementing coprocessors for control processors uses synchronous logic design method to achieve low cost and high performance in control processors. The coprocessor comprising of signed two's complement multiplication, signed divide, shift left and shift right, and normalization comprises of most of the math functions required for implementing digital signal processing algorithms. The processor coprocessor architecture uses data dependency to compute the time duration required to perform the math computation. This results in efficient implementation of DSP algorithms and eventually translates to better system level performance. The technique described to implement math computations uses a register file interface, existing instruction set, and existing legacy software development infrastructure to implement DSP systems.

US Classification:

713/320000

Abstract:

Industrial electronics and many consumer applications need lower cost, lower power consumption, control processing, and some DSP function capability. The technique described implements a system design with industrial and consumer applications in mind. The processor coprocessor architecture with freeze state method to implement power management also provides efficient software programming. Higher number of DSP computations can be programmed as hardware coprocessors functions. Recognizing the completion of DSP computation and implementing power management based on that can be a hardware function. This method of combining DSP computations and power management results in system that can find widespread use in industrial and consumer applications. The technique of using freeze state and implementing power management can also be used in non-battery applications in which power conservation is required.

H04L 29/06

Abstract:

A trained model may be deployed to an Internet-of-Things (IOT) operational environment in order to ingest features and detect events extracted from network traffic. The model may be received and converted into a meta-language representation which is interpretable by a data plane engine. The converted model can then be deployed to the data plane and may extract features from network communications over the data plane. The extracted features may be fed to the deployed model in order to generate event classifications or device state classifications.
