20090279562 | Content-aware dynamic network resource allocation - Network resources allocated for particular application traffic are aware of the characteristics of L4+ content to be transmitted. One embodiment of the invention realizes network resource allocation in terms of three intelligent modules, gateway, provisioning and classification. A gateway module exerts network control functions in response to application requests for network resources. The network control functions include traffic path setup, bandwidth allocation and so on. Characteristics of the content are also specified in the received application network resource requests. Under request of the gateway module, a provisioning module allocates network resources such as bandwidth in optical networks and edge devices as well. An optical network resource allocation leads to a provisioning optical route. Under request of the gateway module, a classification module differentiates applications traffic according to content specifications, and thus creates and applies content-aware rule data for edge devices to forward content-specified traffic towards respective provisioning optical routes. | 11-12-2009 |
20100217854 | Method and Apparatus for Intelligent Management of a Network Element - A network element (NE) includes an intelligent interface (II) with its own operating environment rendering it active during the NE boot process, and with separate intelligence allowing it to take actions on the NE prior to, during, and after the boot process. The combination of independent operation and increased intelligence provides enhanced management opportunities to enable the NE to be controlled throughout the boot process and after completion of the boot process. For example, files may be uploaded to the NE before or during the boot process to restart the NE from a new software image. The II allows this downloading process to occur in parallel on multiple NEs from a centralized storage resource. Diagnostic checks may be run on the NE, and files, and MIB information, and other data may be transmitted from the II to enable a network manager to more effectively manage the NE. | 08-26-2010 |
20140012991 | GRID PROXY ARCHITECTURE FOR NETWORK RESOURCES - A Grid Proxy Architecture for Network Resources (GPAN) is proposed to allow Grid applications to access resources shared in communication network domains. GPAN bridges Grid services serving user applications and network services controlling network devices through its proxy functions such as resource data and management proxies. Working with Grid resource index and broker services, GPAN employs distributed network service peers (NSP) in network domains to discover, negotiate and allocate network resources such as bandwidth for Grid applications. An elected master NSP is the unique Grid node that runs GPAN and represents the whole network to share network resources to Grids without Grid involvement of network devices. GPAN provides the Grid Proxy service (GPS) to interface with Grid services and applications, and the Grid Delegation service (GDS) to interface with network services to utilize network resources. Resource-based XML messaging is employed for the GPAN proxy communication. | 01-09-2014 |

Grid Proxy Architecture for Network Resources (GPAN) bridges Grid services serving user applications and network services controlling network devices through proxy functions. At times, GPAN employs distributed network service peers (NSP) in network domains to discover, negotiate and allocate network resources for Grid applications. An elected master NSP is the unique Grid node that runs GPAN and represents the whole network to share network resources to Grids without Grid involvement of network devices. GPAN provides the Grid Proxy service (GPS) to interface with Grid services and applications, and the Grid Delegation service (GDS) to interface with network services to utilize network resources. In some cases, resource-based XML messaging can be employed for the GPAN proxy communication. | 02-26-2015 |

20130011704 | Redox Flow Battery System with Multiple Independent Stacks - A redox flow battery system is provided with independent stack assemblies dedicated for charging and discharging functions. In such a system, characteristics of the charging stack assembly may be configured to provide a high efficiency during a charging reaction, and the discharging stack may be configured to provide a high efficiency during a discharging reaction. In addition to decoupling charging and discharging reactions, redox flow battery stack assemblies are also configured for other variables, such as the degree of power variability of a source or a load. Using a modular approach to building a flow battery system by separating charging functions from discharging functions, and configuring stack assemblies for other variables, provides large-scale energy storage systems with great flexibility for a wide range of applications. | 01-10-2013 |
20140057141 | PRESSURE BALANCING OF ELECTROLYTES IN REDOX FLOW BATTERIES - Methods and apparatuses are disclosed for mitigating electrolyte migration in a redox flow battery system. A first parameter of a first electrolyte in a first flow path of a redox flow battery cell block may be measured. The first flow path may have an inlet to and an outlet from the redox flow battery cell block. A second parameter of a second electrolyte in a second flow path of the redox flow battery cell block may be measured. The second flow path may have an inlet to and an outlet from the redox flow battery cell block. The first parameter may be detected to be greater than the second parameter. A first device coupled to the redox flow battery cell block in the second flow path may be operated to increase the second parameter in the second flow path. | 02-27-2014 |
20140186731 | Operating A Redox Flow Battery With A Negative Electrolyte Imbalance - Loss of flow battery electrode catalyst layers during self-discharge or charge reversal may be prevented by establishing and maintaining a negative electrolyte imbalance during at least parts of a flow battery's operation. Negative imbalance may be established and/or maintained actively, passively or both. Actively establishing a negative imbalance may involve detecting an imbalance that is less negative than a desired threshold, and processing one or both electrolytes until the imbalance reaches a desired negative level. Negative imbalance may be effectively established and maintained passively within a cell by constructing a cell with a negative electrode chamber that is larger than the cell's positive electrode chamber, thereby providing a larger quantity of negative electrolyte for reaction with positive electrolyte. | 07-03-2014 |
