Based on the assessed load, the PSN in some embodiments also has one or more SSNs added to or removed from its SN group. To add or remove an SSN to or from the service node group, the PSN in some embodiments directs a set of controllers to add (e.g., instantiate or allocate) or remove the SSN to or from the SN group. Also, to assess the load on the service nodes, the PSN in some embodiments receives message load data from the controller set, which collects such data from each service node. In other embodiments, the PSN receives such load data directly from the SSNs. | 2016-03-31 |
20160094390 | DYNAMIC DATA ACCESS CONFIGURATION - One or more techniques and/or systems are provided for dynamic data access configuration. For example, a mapping may be maintained for compute nodes of a distributed processing system. The mapping may comprise access permission assignments of at least some compute nodes to shared data segments (e.g., read access and/or write access permissions). The mapping may be updated based upon configuration changes for the distributed processing system (e.g., addition of a new compute node, failure of a compute node, granting or removal of access to a shared data segment for an existing compute node, etc.). The updated mapping may be applied to the distributed processing system during operation of the distributed processing system (e.g., access may be granted to original instances of shared data segments based upon the configuration change; compute nodes and/or the distributed processing system may be kept online and operational while applying the configuration change; etc.). | 2016-03-31 |
20160094391 | AUTOMATED COMPUTING SYSTEM PERSONALIZATION - The personalization of the functionality of a computing system. In response to identifying the user to personalize its functionality to, the computing system self-personalizes by automatically requesting personalization information for the identified user from a remote personalization engine. The resulting received personalized information is then applied to the computing system to at least partially personalize the functionality of the computing system to the identified user. | 2016-03-31 |
20160094392 | Evaluating Configuration Changes Based on Aggregate Activity Level - Disclosed are various embodiments for computing and using an aggregate activity level for a computing system. Activity level metrics are obtained from a corresponding plurality of components in a data center. A current aggregate activity level request is received. An aggregate activity level is computed from the activity level metrics. The aggregate activity level is compared to a baseline aggregate activity level. In response to the request, an indication is provided as to whether the aggregate activity level falls within a predefined range of the baseline aggregate activity level. | 2016-03-31 |
20160094393 | MANAGEMENT APPARATUS, METHOD OF MANAGING A NETWORK AND STORAGE MEDIUM - A management apparatus that manages a network apparatus having a packet control function, wherein the network apparatus has configuration information that sets the control function, and wherein the management apparatus has: parameter information that manages settings of the control function of the network apparatus; and an inconsistent data detection module that obtains the configuration information from the network apparatus, and upon comparison of the configuration information with the parameter information, detects, as inconsistent data, information that does not match. | 2016-03-31 |
20160094394 | ZERO TOUCH CONFIGURATION AND SYNCHRONIZATION OF A SERVICE APPLIANCE IN A NETWORK ENVIRONMENT - An example method for zero touch configuration and synchronization of a service appliance in a network environment includes receiving, at an appliance port on a service appliance, an indication that a switch port on a switch changed from an inactive status to an active status, the appliance port being connected over a network to the switch port, starting a bootstrap protocol, including by receiving at the service appliance from the switch, a bootstrap message from a service executing in the switch, creating, by the service appliance, an empty port channel at the service appliance, adding, by the service appliance, the appliance port to the port channel, and associating, by the service appliance, the service to the port channel in a cache. | 2016-03-31 |
