One method includes collecting wireless network performance parameters at a location of the network, observing at least one of activities and conditions of the wireless network over the period of time, and correlating the wireless network performance parameters with at least one of the activities and conditions of the wireless network. The wireless network performance parameters can be collected by one or more test devices operating at nodes or clients within the wireless network. | 10-09-2008 |
20080291929 | Providing connectivity between subnets of a wireless network - A method of providing connectivity between subnets of a wireless network is disclosed. The method includes each gateway of each subnet selecting less than all gateways of each other subnet of the wireless network. An adjacency is formed between each gateway and each of the less than all selected gateways of each other subnet. | 11-27-2008 |
20100202397 | Wireless Routing Based On Data Packet Classfication - Apparatuses and methods of using multiple radios of a wireless access node of a wireless network are disclosed. One method includes selecting a 4.9 GHz radio exclusively for public safety data packets, selecting other radios for other types of data packets, and selecting other radios for public safety data packets depending upon specification by a network operator. | 08-12-2010 |
20110188402 | Adaptively Capping Data Throughput of Client Devices Associated with a Wireless Network - A methods and apparatuses of adaptively capping data throughput of client devices associated with a wireless network are disclosed. One method includes monitoring an air-time per bit efficiency of each client device associated with the wireless network. A data throughput cap for each client device is adaptively determined based on the air-time per bit efficiency of the client device. | 08-04-2011 |
20140310408 | HANDLING CHANGES IN A DISTRIBUTED NETWORK MANAGEMENT SYSTEM THAT USES A LOGICAL MULTI-DIMENSIONAL LABEL-BASED POLICY MODEL - A change to a state of a particular managed server within an administrative domain is processed. The administrative domain includes a plurality of managed servers that use management instructions to configure management modules so that the configured management modules implement an administrative domain-wide management policy that comprises a set of one or more rules. A first description of the particular managed server is modified to indicate the particular managed server's changed state, thereby specifying a second description of the particular managed server. The unmodified first description is compared to the second description, thereby specifying a description change. A determination is made, based on the description change, regarding whether to update management instructions previously sent to the particular managed server. | 10-16-2014 |
20140310415 | DISTRIBUTED NETWORK MANAGEMENT USING A LOGICAL MULTI-DIMENSIONAL LABEL-BASED POLICY MODEL - Management instructions for a particular managed server within an administrative domain are generated according to an administrative domain-wide management policy that comprises a set of one or more rules. The administrative domain includes a plurality of managed servers. A determination is made regarding which rules within the set of rules are relevant to the particular managed server. Function-level instructions are generated based on the rules that were determined to be relevant. A determination is made regarding which managed servers within the plurality of managed servers are relevant to the particular managed server. The function-level instructions and information regarding the managed servers that were determined to be relevant are sent to the particular managed server. The particular managed server uses the function-level instructions and information regarding the managed servers to configure a management module so that the configured management module implements the administrative domain-wide management policy. | 10-16-2014 |
20140373091 | Distributed Network Security Using a Logical Multi-Dimensional Label-Based Policy Model - A managed server (MS) within an administrative domain is quarantined. The administrative domain includes multiple MSs that use management instructions to configure management modules so that the configured management modules implement an administrative domain-wide management policy that comprises a set of one or more rules. The quarantined MS is isolated from other MSs. A description of the MS is modified to indicate that the MS is quarantined, thereby specifying a description of the quarantined MS. Cached actor-sets are updated to indicate the quarantined MS's changed state, thereby specifying updated actor-sets. A determination is made regarding which updated actor-sets are relevant to an other MS, thereby specifying currently-relevant updated actor-sets. A determination is made regarding whether the currently-relevant updated actor-sets differ from actor-sets previously sent to the other MS. Responsive to determining that the currently-relevant updated actor-sets are identical to the previously-sent actor-sets, no further action is taken. | 12-18-2014 |
20150127832 | Pairing in a Distributed Network Management System that Uses a Logical Multi-Dimensional Label-Based Policy Model - A server is paired. A pairing request that includes a pairing key is received from an unpaired server. A determination is made regarding whether to approve or reject the pairing request. Making the determination comprises attempting to validate the pairing key in the pairing request. Responsive to determining to approve the pairing request: the unpaired server is notified that the unpaired server is now a managed server; a description of the managed server is generated, wherein the managed server description includes a set of one or more labels that describe the managed server; management instructions are generated for the managed server based on the managed server description and based on an administrative domain-wide management policy that includes a rule that refers to managed servers using a label; and the management instructions are sent to the managed server. | 05-07-2015 |
20150128211 | AUTOMATED GENERATION OF ACCESS CONTROL RULES FOR USE IN A DISTRIBUTED NETWORK MANAGEMENT SYSTEM THAT USES A LABEL-BASED POLICY MODEL - An access control rule authorizing communication between a plurality of managed servers within an administrative domain is determined. Communication information describing past communication between the plurality of managed servers is obtained. A subset of managed servers from the plurality of managed servers is identified by grouping the plurality of managed servers based on the obtained communication information. A group-level label set is determined to associate with the subset of managed servers. Role labels are determined for managed servers in the subset of managed servers. A managed server is associated with one role label. Based on the group-level label set and the role labels, an access control rule is generated authorizing communication between a first managed server of the subset of managed servers and a second managed server. The access control rule is stored as part of an administrative domain-wide management policy. | 05-07-2015 |
