Methods and systems are provided. A method includes managing, by a software defined network (SDN) controller, OpenFlow rules stored on an OpenFlow network device having a ternary content addressable memory (TCAM). The OpenFlow rules include unreachable OpenFlow rules and reachable OpenFlow rules. The managing step includes querying at least one OpenFlow rule from among the unreachable OpenFlow rules and the reachable OpenFlow rules on the at least one OpenFlow network device. The managing step further includes determining whether any of the OpenFlow rules are reachable or unreachable from indicia used to mark the OpenFlow rules as reachable or unreachable. The managing step also includes causing a removal of the unreachable OpenFlow rules from the OpenFlow network device.

Management of unreachable openflow rules

Techniques for power savings in communications equipment are provided. The computer-implemented method can comprise identifying, by an electronic device operatively coupled to a processing unit, one or more connectivity requirements of one or more servers associated with a data center. The computer-implemented method can also comprise determining, by the electronic device, a defined graph that satisfies the one or more connectivity requirements. The computer-implemented method can further comprise powering down, by the electronic device, one or more elements of the data center that are not required by the defined graph; and powering up, by the device one or more nodes of the data center, which are in any state other than power up, that are required by the defined graph.

Method and apparatus for power savings in communications equipment

Systems, methods and apparatus, including computer program products, are disclosed for regulating access of consumers (e.g., applications, containers, or VMs) to resources and services (e.g., storage). In one embodiment, this regulation occurs through the movement of consumers between different providers of a resource or service, such as a cloud service provider. Moving consumers includes, for example, determining the cost of moving the consumer from a first provider to a second provider. According to various embodiments, the cost of moving the consumer is compared to performance criteria associated with moving the consumer from the first provider to the second provider.

Systems, apparatus and methods for cost and performance-based movement of applications and workloads in a multiple-provider system

Systems, apparatus and methods are disclosed which are directed to computer program products for managing multiple instances of an application or other entities, including managing instances of an application or other entities across multiple environments, in each case while assuring application performance to the extent possible given the resources available. The disclosed management software and/or processes may also be used to ensure that an application is running in multiple geo localities (e.g., discrete and/or physically separated geographical locations).

Management of unreachable OpenFlow rules

Systems, methods and apparatus, including computer program products, are disclosed for management of resources and services (e.g., storage, registers, memory, ternary content-addressable memory (TCAM) tables) to route packet sequences in a software-defined networking (SDN) environment. In one embodiment, this management occurs through the use of supply chain economics to manage utilization of TCAM resources.

Systems, apparatus and methods for managing resources in computer systems

A method and system are provided. The method includes automatically transferring configuration information from at least one network device to at least one software defined networking controller. The automatically transferring step includes retrieving configuration information associated with the at least one network device, converting the configuration information into a format usable by the at least one software defined networking controller, and configuring the at least one software defined networking controller with the converted configuration information.

Automated configuration of software defined network controller

A downstream element in a pipeline processing a network flow receives a first request and executes an indexing function to compute an index into a control block for storing state information associated with the data packet. The downstream element transmits a request to an upstream element to include the index as a tag in one or more subsequent data packets that comprises the plurality of network fields and the associated values. Subsequent data packet may be received at the downstream element with the tag having the index information. The downstream element may process the subsequent data packet based on the tag without having to execute the indexing function on the subsequent data packet.
