A method, system, and computer program product for monitoring service tickets for information technology (IT) service providers to ensure that levels of service regarding resolving problems identified by a customer are met is provided. In one embodiment, a monitoring server inspects a service ticket in a database to determine a deadline for when a problem associated with the service ticket must be resolved. The server then determines a deadline approaching alert time. This deadline approaching alert time is a time at which a help desk user must be notified that the deadline for resolving the problem must be met is approaching. The server then alerts the help desk user that the deadline for resolving the problem is approaching when the deadline approaching alert time is reached. If the problem is not resolved by the deadline, the server periodically alerts the help desk user when times for status updates, which have been specified by a level of service agreement for updating the customer of the status of resolution of problems that have past deadline, are approaching, thereby ensuring that the IT provider meets its obligations to the customer.

A method and system is provided intelligent network dispatchers that are capable of routing requests to one or more servers (e.g., LDAP servers) based on the requested application or the identity of the requester. The servers may be grouped into virtual clusters so that a particular cluster may service requests associated with a particular application or based on a type of customer (e.g., preferred or general customer) in order to grade levels of service. Also, a system resource monitor may provide continual monitoring of servers in virtual clusters to determine when one or more servers are overburdened or under burdened based on statistical performance data. As a servers performance changes, the system resource monitor may advise the intelligent network dispatcher causing a change in the rate of requests to the overburdened / under burdened server. The server may be temporarily removed from the virtual cluster until performance levels normalize. Further, servers may be re-assigned to other virtual clusters on demand to provide increased capacity to a virtual cluster.

A method and apparatus for adaptively targeting advertisements to a specific client computer from a server within a distributed data processing system is provided. As a user of the client browses the World Wide Web, the material that is downloaded to the client constitutes a datastream. At some location during the routing of the datastream, either on the server or at the client, the datastream is scanned to generate a list of keywords that are present within the datastream. The datastream may be analyzed in real-time or cached and analyzed on a delayed basis. The generated list of keywords represents a summary of the content that appears to be the focus of interest of the user. The keywords are compared against a database of advertisements, and the server selects an advertisement that matches the user's area of interest in comparison to the analysis of the user's browsing history. The selected advertisement is then inserted into the datastream to be routed to the client. In consideration for viewing targeted advertisements and to entice a Web viewer to allow the monitoring of a datastream so that targeted advertisements may be placed into the datastream, a Web viewer may receive online connection service for free, for a reduced cost, at a premium level of service, or for other some other value, such as frequent viewer credits that may be exchanged for goods and services.

By abstracting the Cloud services, the dynamic Cloud services registry creates a modular package of different services from different Cloud service providers based on the query and requested priority for services. The dynamic Cloud registry is dynamically updated based on the level of services that the provider has available. The dynamic registry determines what service best matches the requirements from a Cloud service request (CSR) and returns a personalized set of matching services.

A dynamic upstream bandwidth allocation scheme is disclosed, i.e., limited sharing with traffic prediction (LSTP), to improve the bandwidth efficiency of upstream transmission over PONs. LSTP adopts the PON MAC control messages, and dynamically allocates bandwidth according to the on-line traffic load. The ONU bandwidth requirement includes the already buffered data and a prediction of the incoming data, thus reducing the frame delay and alleviating the data loss. ONUs are served by the OLT in a fixed order in LSTP to facilitate the traffic prediction. Each optical network unit (ONU) classifies its local traffic into three classes with descending priorities: expedited forwarding (EF), assured forwarding (AF), and best effort (BE). Data with higher priority replace data with lower priority when the buffer is full. In order to alleviate uncontrolled delay and unfair drop of the lower priority data, the priority-based scheduling is employed to deliver the buffered data in a particular transmission timeslot. The bandwidth allocation incorporates the service level agreements (SLAs) and the on-line traffic dynamics. The basic limited sharing with traffic prediction (LSTP) scheme is extended to serve the classified network traffic.
