摘要： An output stage comprising a current mode line driver, a voltage mode line driver, and a center-tapped transformer for coupling data provided by the line drivers to a transmission line is provided herein. The output stage is configured to operate in a backwards compatible Ethernet communication device. For example, the Ethernet communication device is configured to support 10G Ethernet and legacy Ethernet modes of 10BASE-T, 100BASE-T, and 1000BASE-T. The current mode line driver can be utilized while operating in the 10G Ethernet mode to provide high linearity. The voltage mode line driver can be utilized while operating in legacy mode to conserve power. In order to accommodate the use of two different line drivers, a switch and/or a voltage regulator is used to couple/decouple a dc voltage to a center-tap of the transformer based on which of the two different line drivers is currently active.

摘要： A method and system for adjudicating measurement data in real time and re-adjudicating a segment of an input measurement data stream upon submission of a new adjudication instruction in a service level evaluation system. An adjudication instruction associated with a service level is received. Measurement data including a first measurement data point is received. The received adjudication instruction is applied in real time to the first measurement data point to generate a first adjudicated measurement data point. A service level is evaluated based on the first adjudicated measurement data point. To re-adjudicate the data stream segment, a new adjudication instruction is received and the segment is identified. The input data stream's adjudication is suspended and the stream is queued into storage. The segment of measurement data is retrieved and re-adjudicated by applying the new adjudication instruction. The input data stream's adjudication is resumed afterwards from the queued input stream.

摘要： A method for facilitating compliance testing in an information technology (IT) environment is provided. The method includes defining each IT component of an enterprise as a set of attribute value pairs represented as a configuration item (CI) and defining relationships among the CIs. Configuration Standards for the CIs are defined to include scope identifying CIs to which the Configuration Standards apply and restrictions defining requirements for compliance. Compliance testing is performed for IT components of the enterprise against a selected Configuration Standards by determining, depending on the scope and the restrictions of each of the selected Configuration Standards, which of the IT components within the scope of the selected Configuration Standards fails to meet the restrictions of respective ones of the selected Configuration Standards; and by outputting results as a list, which includes each of the IT components that failed to meet respective ones of the selected Configuration Standards.

摘要： Methods, apparatus and computer program products decompose a service process into service process operations; filter the service operations based on at least one pre-determined criterion; identify at least one different service process operation to be used to replace an existing service process operation; and replace the existing service process operation with the at least one different service process operation. The service process can be decomposed using specific service features derived from reference service processes. The pre-determined criterion used to filter the service operations can constitute a service level; a service category; or a service process feature. A service process feature describes core functionality of the service.

摘要： The present invention relates to the problem of scheduling work for employees and/or other resources in a help desk or similar environment. The employees have different levels of training and availabilities. The jobs, which occur as a result of dynamically occurring events, consist of multiple tasks ordered by chain precedence. Each job and/or task carries with it a penalty which is a step function of the time taken to complete it, the deadlines and penalties having been negotiated as part of one or more service level agreement contracts. The goal is to minimize the total amount of penalties paid. The invention consists of a pair of heuristic schemes for this difficult scheduling problem, one greedy and one randomized. The greedy scheme is used to provide a quick initial solution, while the greedy and randomized schemes are combined in order to think more deeply about particular problem instances. The invention also includes a scheme for determining how much time to allocate to thinking about each of several potential problem instance variants.
摘要翻译：本发明涉及在帮助台或类似环境中调度员工和/或其他资源的工作的问题。员工具有不同的培训水平和可用性。由于动态发生的事件而发生的作业由链优先级排序的多个任务组成。每项工作和/或任务带有罚款，这是完成它所需的时间的一个阶段功能，作为一个或多个服务级别协议合同的一部分，谈判达成的期限和处罚。目标是尽量减少所支付的罚款总额。本发明由一对启发式方案组成，用于这个困难的调度问题，一个是贪心的，一个是随机的。贪心的方案用于提供一个快速的初步解决方案，而贪心和随机的方案是相结合的，以便更深入地思考特定的问题实例。本发明还包括一种用于确定分配多少时间以考虑几个潜在问题实例变体中的每一个的方案。
