• Duration: Nov 07 – Feb 2010
• Performance management is an important aspect of total systems management. To achieve an effective performance management strategy, it is important for the systems administrator and capacity planner to address two fundamental concerns:
• The ability to perform long-term planning and trend analysis.
• Performance Management provides the tools to extract performance data and present it in a spreadsheet format, making it possible to see trends that have occurred over long periods of time and to compare one machine with another. Performance Management comprises four components that present computer usage and performance data in an easy-to-comprehend, graphical form.
• Performance Configuration
• Lets you configure Performance Agents and Performance data gathering policies (profiles) across your enterprise.
• Performance Scope
• Provides a real-time view of performance for the components of managed systems.
• Performance Trend
• Facilitates capacity management by providing historical performance and usage information in a spreadsheet where it can be displayed and analyzed.
• Chargeback
• Allocates resource accounting data obtained from heterogeneous platforms across the enterprise to “real-world” charge groups.
• Performance Management employs the Performance Agent to collect performance-related data on the distributed systems. The agent collects information from a variety of systems and database resources for many platforms, including Linux/Unix, and Windows. The performance information collected varies by environment.
• Technologies: C++, C, JSP and JAVA, LINUX, AIX, Solaris and Windows, MSSQL server and Multi-Threading. Achieved a part of ownership of the module.
• I have handled a Change Request from client.
• I was able to successfully solve most of the critical issues in the Agent, Scope, Trend and Configuration.

• Description: This project is to provide MDF (Multimedia Description Framework) plugins On OMAP 2420 platform (Confidential: for a leading mobile company phone).
• OMAP 2420 chip, provided by TI consists of
• i) Arm11 processor on which Symbian OS will be running.
• ii) DSP processor for audio functioning
• iii) And IVA (image video accelerators) which boosts the performance of video image processing like encoding and decoding.
• The aim is to implement the four hardware devices
• 1) Preprocessor HW device
• 2) Encoder HW device
• 3) Decoder HW device
• 4) Postprocessor HW device.
• These plug-ins are implemented using Symbian client server framework with extensive use of Asynchronous programming, Shared memory usage across processes (chunk memory) and object oriented programming.
• Module Description: Postprocessor HW Device
• Postprocessor takes an uncompressed video data as input from a decoder or directly and performs post processing operations like scaling, rotation, clipping, deranging, de-blocking, mirroring and color conversions and gives the output to either screen or memory out.
• Technologies : Symbian, C++, Symbian Client Server Frame work and Multi-Threading application.; I have served as team member responsible for Design and Implementation of the Postprocessor HW Device.
• Achieved a part of ownership of the module and met all requirements in extremely demanding schedules.
• I have handled a Change Request from client.
• I was able to successfully solve most of the critical issues in the video playback.

• Enhanced QoS Multicast routing Protocol (EQMRP) (Linux)
• Many internet multicast applications have quality-of-service (QoS) requirements .The requirements can be additive (end-to-end delay), multiplicative (loss rate).A new enhanced QoS multicast routing protocol (EQMRP) that has very small communication over head and requires no state outside the multicast tree. Its early warning mechanism (EW) helps to detect and route around the real bottlenecks in the network, which increases the chance of finding feasible paths for additive QoS requirements. EQMRP minimizes the system requirements, it relays only on the local state stored at each router.
• EQMRP shares the adaptive path branching idea of QMRP, but eliminates the temporary use of per-group-per-join routing state. In QMRP, each new member initiates a search tree, which grows towards the multicast tree. The search tree is per join state information. In EQMRP, the multicast tree grows towards the new members. The protocol does not require storing any extra routing state other than the multicast tree itself. It not only gets rid of per join routing state but also allows the dynamic aggregation of multiple join requests, where a singletree branch may grow toward multiple new members. By eliminating the search tree, EQMRP removes the state machine in QMRP that governs the construction of the search tree, and therefore simplifies the implementation. EQMRP uses a novel early-warning (EW) mechanism that takes the additive nature of the delay requirement into account and attempts to identify the most appropriate point to explore alternative paths in order to maximize the chance of success.
