One method includes collecting and measuring application level key performance indicators, detecting user actions by monitoring network side user traffic in a network, correlating the user actions with the application level key performance indicators in order to evaluate and quantify a quality of experience (Qo E) of the user, and correlating poor Qo E with network side key performance indicators in order to determine an underlying root cause of the poor Qo E. | 2016-03-03 |
| 20160065420 | INCREASING THE ACCURACY OF SERVICE QUALITY MANAGEMENT METRICS - According to embodiments of the present invention, one or more computer processors determine a source for a performance indicator of a target service element is known. The one or more computer processors select, at run time, a source for the performance indicator that has a least amount of information gaps. The one or more computer processors determine information associated with the performance indicator from the source. The one or more computer processors determine whether the determined information associated with the performance indicator is more current than a quality indicator periodicity value that is associated with the target service element. In response to determining that the determined information associated with the performance indicator is more current than a quality indicator periodicity value that is associated with the target service element, the one or more computer processors selecting the performance indicator. | 2016-03-03 |
| 20160065421 | SERVICE LEVEL AGREEMENT (SLA) COGNIZENT SELF-MANAGING DATABASE CONNECTION POOLS IN A MULTI-TENANT ENVIRONMENT - Embodiments of the invention provide a method, system and computer program product for SLA cognizant database connection management for multi-tenant environments. In an embodiment of the invention, a method for SLA cognizant database connection management for multi-tenant environments includes receiving different requests for data in a database from different application instances executing in memory of a host computing system supporting a multi-tenant computing environment and determining a priority for each of the requests. The method also includes selecting for each request a particular portion of a database connection pool of a multiplicity of database connections to the database, in that the particular portion is associated with a corresponding priority of the request, and each portion of the database connection pool includes one or more of the database connections. Finally, the method includes processing each of the requests through a respectively selected one of the portions of the database connection pool. | 2016-03-03 |
| 20160065422 | BANDWIDTH ON DEMAND IN SDN NETWORKS - Bandwidth-on-Demand (BoD) as a network service (BoD-as-a-Service) is integrated into applications that end-users can flexibly purchase when and for however long they need it. A centralized Software Defined Networking (SDN) controller and distributed SDN controller agents that may be seen in a Service Provider, Enterprise or distributed computing environment with remote and mobile end-users is provided. The end-user initiates the BoD request using an application via desktop, cloud, smartphone or tablet. The BoD Service Provider, Enterprise, has a controller-based centralized view of the complete SDN service topology. On receiving the request, the BoD provider dynamically computes the optimal end-to-end path through the SDN topology that best suits the end-user requested traffic types and service level requirements. It then translates that optimal path into flow computations that are dynamically pushed down to the controller agents to provision the BoD network path in real-time. An on-demand and real-time bandwidth service for consumers are herein provided where it was previously too costly or too time consuming to set up. | 2016-03-03 |
| 20160065423 | Collecting and Analyzing Selected Network Traffic - A tracking system is described herein for investigating the behavior of a network. In operation, each switch in the network (or each switch in some subset of switches) may determine whether each original packet that it processes satisfies one or more packet-detection rules. If so, the switch generates a mirrored packet and sends that packet to a load balancer multiplexer, which, in turn, forwards the mirrored packet to a processing module for further analysis. The packet-detection rules hosted by the switches can be designed to select a subset of packets that are of greatest interest, based on any environment-specific objectives. As a result of this behavior, the tracking system can effectively and quickly pinpoint undesirable (and potentially desirable) behavior of the network, without being overwhelmed with too much information. | 2016-03-03 |
| 20160065424 | Network Congestion Analysis - A network monitoring and network congestion analysis can be performed based on a comparison of data packets at multiple different network nodes installed at different locations on a communication path. A downstream network node may be installed at a user location while an upstream network may be installed at an access router further up the network. A network congestion analyzer may receive data packet information including timestamps from both network nodes, and may compare the data packet information to group the data packets into application flows and match the corresponding packets from the different network nodes. Based on the data packet matching, the network congestion analyzer may calculate packet loss, packet delay, packet delay variation, and perform other network congestion analysis techniques for the application flows corresponding to a user's various devices and the applications executing on those devices. | 2016-03-03 |
| 20160065425 | VISUAL REPRESENTATIONS OF STATUS - An example device in accordance with an aspect of the present disclosure is to generate a visual representation of a status of a metric. The visual representation is to be updated according to the granularity during at least a portion of a time period. The visual representation is to depict passage of time along a first dimension, and is to separate the time period into a plurality of time blocks to be depicted as being stacked along a second dimension of the visual representation. | 2016-03-03 |
