1 WebNMS Case Study Industry: Highlights: Broadband Service provider Seamless integration with applications and network elements such as Alcatel 1648 SM, Nortel Networks S/ DMS OC 48 Transport Node, etc. Business Challenge: To provide a highly-scalable and integrated network management platform for effectively managing s heterogeneous infrastructure consisting of multi-vendor/ multi-technology network elements and management applications. Unified platform that encompasses the entire infrastructure Integrated and comprehensive fault and performance management functions Highly-scalable and flexible architecture that allows deployment flexibility and ease of integration Solution: Engineers at built a truly unified management application, Quality Management System (QMS ), using the carrier class management platform Web NMS Framework. Comprehensive inventory repository Unified client for consistent and easy visualization of alerts and performance data Benefits: The responsiveness of the AdventNet support was without doubt, commendable. Chih Wei Chang Project Senior Researcher, QMS eliminates the need for expensive infrastructure forklifts to unify the network operations. Operators can proactively monitor service-affecting metrics and resolve them beforehand. Intuitive display schemas enable operators to manage the infrastructure effectively and efficiently ZOHO Corporation WebNMS is a trademark of ZOHO Corporation All other trademarks are property of their respective owners.

2 Business Challenge: provides high-performance telephony, broadband, data communication, Internet, and wireless services to over 20 million subscribers in Taiwan and the offshore islands. relies fully on its network infrastructure for its day-to-day operations. s infrastructure is an expansive heterogeneous transmission network composed of network elements and management applications from established vendors, such as Nortel Networks, Alcatel, and NEC among others. The infrastructure is managed by a diverse set of standard protocols such as SNMP, TL1, and CLI as well as proprietary protocols. Enabling interoperability and tight integration in such networks is a daunting challenge. Streamlining operations that involve interactions between multi-vendor multi-technology entities has been traditionally achieved by introducing protocol and function specific adapters. However, as the number and complexity of network elements increase, this model becomes prohibitively expensive and complex. was looking for an integrated and highly-scalable platform to enable management across various elements and management applications. AdventNet supported us through a dedicated offshore engineering team ensuring the completion of the design, development, and deployment of QMSTM ahead of our ambitious schedule.

3 Solution: selected WebNMS s carrier class network management platform, Web NMS, for its management software development project. The engineers at rapidly developed the Quality Management System (QMS ), a management solution that seamlessly integrates applications and Network Elements (NEs) such as Alcatel 1648 SM, Nortel networks S/DMS OC48 Transport Node, etc, and effectively manages s complex network infrastructure. The carrier environment at companies, such as Chunghwa Telecom, is continually growing in size and complexity, which drives the need for greater control through more automated management and centralized operations. The Web NMS product provides an essential management platform for ensuring the effective delivery of services, enabling to remain competitive. Sridhar Vembu, CEO AdventNet Inc. WebNMS Framework provided hooks for all the requirements of and facilitated rapid development of the application with its out-of-the-box FCPS functionalities, open standard northbound interfaces, scalable n-tier architecture, inventory management, provisioning, and intuitive GUI. Using Web NMS, we were able to achieve a closely-knit infrastructure at a fraction of the cost and time compared to other alternatives. With this approach, our network architects and operations personnel can increasingly focus on their core tasks network planning and design, evolution and operations to extract the highest quality, reliability, availability and performance from our networks, and maximize the ROI from our infrastructure investment Ms. Li Hsiou Wu, Chief Researcher at 3

4 Key benefits: Business Benefits and Sustained Value Addition With the seamless integration of existing applications and network components, s QMS eliminates the need for expensive infrastructure forklifts to unify the network operations and opens a low-cost path to integrate new NEs and the associated management applications. The unified platform for managing the network enables s management team to plan and harvest the long-term benefits of an optimally designed network infrastructure that scales with the growing network. Effective and Predictive Operations Management Armed with an informed perspective of service-affecting conditions, Chunghwa Telecom s operations personnel are now empowered to proactively monitor the serviceaffecting metrics and initiate preemptive measures to resolve them beforehand. Monitoring the transmission network comprehensively for critical metrics enables the operations personnel to predict possible recurrences of identified network faults, resulting in a resilient network infrastructure.
