BPL Networking Basics, Deployment, and Operations Dial.not Lance Rosen Founder & Partner, Electric Broadband V: 845-348-3194 Email: [email protected] Topics Strategy: Business & Technology BPL Network Design and Architecture Implementation: Deployment & Integration Operating a BPL Network Source: John Patrick, Internet Attitude Goals and Objectives need to be defined during the strategy phase Business Strategy Business Model Technology Strategy Platform Choice(s) Market Demand and initial Deployment Strategy & reach for Broadband Costs Services Applications Systems and Network Integration Financials Operations Strategy: Business & Technology While the overall value chain associated with a BPL business has many components, cooperative utilities have multiple structural options BPL Vendor BPL Strategy BPL Integrator Network Ops Service Provider Design, Integration, and Operations phases Landlord Model Developer Model Service Provider Model Strategy: Business & Technology Electric Utility A powerline network can be thought of as being comprised of three critical pieces that create a seamless broadband infrastructure Source: Ambient Corp. BPL Network Design and Architecture This infrastructure uses the internet suite of protocols based on the ISO - OSI seven-layer model of networking. BPL architectures utilize the OSI model Layer Application Presentation Session Transport Network Datalink Physical OSI Layered Model Function Telnet, HTTP, SMTP, FTP, Gopher, etc... Formating, translation Login, authentication Multiplexed packets (TCP, UDP) End-to-End addressed datagrams (IP) Packets (ethernet, token ring, Frame Relay) Raw bits, coding (coax, UTP, wire, fiber, RF) BPL Applications TCP IP Ethernet Power Line BPL product and software designers implement the OSI model and in some instances have added “additional” control layers The important thing to note in the system architecture is ‘IP’ as the network layer. This allows everything above the network layer to operate independently of the type of link used. BPL Network Design and Architecture While in the design phase, specific network questions are considered Strategic Initiative Interconnecting Broadband Services Network Enabled Applications Network Efficiency How can we beat the competition? How do we interconnect disparate infrastructures? Are Wholesale and Retail Broadband Services to be marketed as part of the business plan? Are Utility Applications implemented and managed? Is Performance Monitoring part of the SLA? Network Administration Who fulfills Network Administration functions (Billing, SLA, Reporting, ...)? Logical Network Management Who provides the Network Operations Center services – 24x7? Physical Network Management What organization monitors and manages the physical Network Elements – 24x7? Hardware Assets What are the differential qualities of the BPL Vendors? Physical Network Who designs and plans the utility Infrastructure, backhaul, and last mile components? BPL Network Design and Architecture And a number of other components must also be designed into the implementation Platform identification and selection BPL architecture design Network engineering Backhaul and Internet connectivity Security (authentication, spamming, pop-ups, etc...) Fault tolerance and redundancy Site Survey data Utility applications? Construction/resource management systems Maintenance and Emergency repair Trouble Management Since BPL is a “hybrid” networking technology it requires at least one type of interface to a backhaul network (fiber, copper, satellite, wireless) BPL Network Design and Architecture What resources are required during the design phase? Technical staff Utility (Substation, Distribution Plant, Operations, Engineering) Telecom (Outside Plant, NOC, Operations) IS (Network Operations, Systems Integration, System Design) If partnering, the consortium of value chain partners is taken under advisement Financial (Business Dev, accounting, revenues (credit, billing), financial analysts) BPL vendor involvement Line crews Site survey teams BPL Network Design and Architecture What is involved with a BPL deployment? Network design Project teams with management authority Line crew involvement and interactivity Tools required for installation Coordination with Partners (ISP, integrators, s/w developers) Testing Implementation: Deployment & Integration And there is a recursive risk mitigation methodology utilized during the deployment phase to help insure avoiding a “death march” Design Develop Deploy Project Management Risk Assessment Change Readiness Results Measurement Network Construction Project Management Tools Required Site Surveys Systems Integration Equipment configuration Network Integration Testing and Acceptance Back Office Integration FCC Part 15 compliance Implementation: Deployment & Integration So what can go wrong during the deployment phase? Short cutting to make budget and time constraints Inadequate installation/user training and support Technical failure (e.g. hardware failures, programming bugs, operational problems) Technical success, business failure (e.g. benefits not achieved) Lack of support from upper management Poor interfaces with existing systems Lack of resources during start-up Unanticipated situations Scope changes Implementation: Deployment & Integration Operating a BPL Network Network Operations Center Network element management Backbone management Help Desk: customer management Customer acquisition and activation (provisioning) Accounting, billing, and reporting Process and roles definition O&M Managing Service Level Agreements (SLA) OSS Asset and element management Operating a BPL Network Monitoring Network Performance Monitoring Network Performance (e.g., SNMP, CPU Loads) Fault Monitoring MIB Browser IP Address Management Diagnostic Tools Security Tools Operating a BPL Network Depending on the BPL model chosen, resources will vary Maintenance NOC Operator Customer Support Billing Operations Utilities can choose their level of involvement based on risk, in-house expertise, and financial condition. Also, value chain partners will play a prominent role in managing and mitigating risk. Operating a BPL Network What’s Next...
