It also: • Describes implementation of the communication network for the Connected Pipeline System and guidance for supporting Supervisory Control and Data Acquisition (SCADA) communication from the Pipeline Network to the Control Center. • Documents best practices from real world implementations, detailing the designs and architectures that are mapped back to the customer use cases. • Addresses real-life customer deployment scenarios by providing a solution that supports implementation of a scalable, secure, and redundant operational network supporting both industrial and multiservice applications. • Details support for implementing redundancy and security for SCADA communication in the Connected Pipeline System. • Specifies topology for high availability, security services, and network management services implementations. • Documents suggested equipment and technologies, system level configurations, and recommendations. • Describes caveats and considerations that pipeline operators should understand as they implement best practices. Document Objective and Scope In this initial release, Cisco has partnered with Schneider Electric to provide architecture, design, and technologies for the Control Centers, Operational Telecoms Network, and the pipeline stations. Cisco provides infrastructure expertise with its unified compute and networking security platforms while Schneider Electric provides the Pipeline Management System (PMS) leadership with its OASyS Dynamic Network of Applications (DNA) SCADA system hardware and software. This document focuses on the pipeline communications network and security architectures to support pipeline operators. It is recommended that the reader become familiar with the following joint Cisco/Schneider Electric white papers: • Integrated Enterprise SCADA System Architectures for Safe and Efficient Pipeline Operations at the following URL: – http://www.cisco.com/c/dam/en/us/solutions/collateral/industry-solutions/dlfe-683318406.pdf Operational Telecom Network for the Connected Pipeline System Implementation Guide v Preface Contributors • Converged Telecommunication Architectures for Effective Integrated Pipeline Operations at the following URL: – http://www.cisco.com/c/dam/en/us/solutions/collateral/industry-solutions/dlfe-683318407.pdf As with any architecture and design program, functional requirements, use cases, and architectures evolve. Therefore, this CVD will evolve and will be updated in future phases.

Operational Telecom Network for the Connected Pipeline System vi Implementation Guide CHAPTER 1 Implementation Overview This chapter includes the following major topics: • Solution Architecture, page 1-3 • Connected Pipeline Network Overview, page 1-4 Cisco has designed an Operational Telecom Network architecture to satisfy communication requirements between the Pipeline Network and the Control Center in the Oil and Gas industry. This is in partnership with Schneider Electric and uses their Programmable Logic Controllers (PLCs) in various pipeline stations such as terminal, pump, and block valve stations. These PLCs provide real-time measurements of the pipeline segment such as temperature and pressure. These measurements have to be reliably communicated to the Control Center, which may be located along the pipeline or situated remotely. Schneider's Enterprise Pipeline Management (ePLM) solution helps operators in Control Centers receive real-time data from the pipeline segment. A Pipeline Management System combines operational SCADA with oil and gas industry-specific real-time applications, host-based leak detection, and historical flow measurement. A well-designed pipeline network architecture provides secure and reliable communication infrastructure. Such an infrastructure uses hardware and software that allows functions to be mobile, scalable, flexible, and robust. The communication infrastructure must provide real-time sharing and collection of pipeline data to the Control Center in safe and efficient manner. Figure 1-1 provides a brief overview of different stations located along the length of a pipeline segment. Some of these stations include: • Terminal Stations—Usually mark the start or end of the pipeline segment for a product. Such

  • The Telecommunication Industry: Cisco and Lucent's Supply Chains
    The Telecommunication Industry: Cisco and Lucent’s Supply Chains by Yishai Boasson M.Eng. Massachusetts Institute of Technology © 2005 Yishai Boasson All rights reserved The author hereby grants to MIT permission to reproduce and to distribute publicly paper and electronic copies of this thesis document in whole or in part. The Telecommunications Industry: Cisco and Lucent’s Supply Chains by Yishai Boasson Abstract This work aims at describing the current trends in supply chain management prevalent in the telecommunications industry. This is done through looking at the telecommunications industry (telephony and data communications), its history and the factors shaping what it currently is. In addition, two companies – Cisco Systems Inc. and Lucent Technologies Inc. are used as two case studies. Looking at these two companies enables us to dive deeper into actual supply chain practices, trying to understand current best practices. As we analyzed these two companies’ supply chains, we used a framework delineated by the belief that excellent supply chain management is a collection of business processes supporting operational goals, which in turn should enable an overall business strategy. Our initial perception of current supply chain practices was shaped by available literature as well as by the image projected by telecommunications companies in forums and publications concerning their supply chain management practices. However, the opportunity to look closely and intimately at one of Cisco’s supply chains has revealed a slightly different picture, where supply chains are not necessarily used as a means to gain sustained competitive advantage. In addition, marked differences in the two companies’ 2 practices might be attributed not only to differing strategies, but also do differing histories.
