1 An Integrated Network Management System for SDH Broadcasting Networks Geneva, June 19th, 2007 EBU NMC Seminar Network 2007-To IP and beyond Speaker: Raffaele Ferrari
2 Rai Radiotelevisione Italiana Company profile RAI RADIOTELEVISIONE ITALIANA TV Production RADIO Production NEWS Rai Trade Rai Sat Rai Net Rai Click Rai Way Rai Way is one of the associate companies of the group in charge of managing the network infrastructure in order to provide the entire national territory with broadcasting services.
3 Rai Radiotelevisione Italiana Rai Way network and services Rai Way Network RAI Way, through its network Waynet, reaches 99 percent of Italy and connects the 21 major Italian cities where television and radio programs are produced. The company manages 2,300 locations throughout Italy. RAI Way also has more than 60 other access points to its transmission network for connecting broadcasting units outside the country. The main broadcasting services which can be provided are as follows : analog terrestrial TV, digital terrestrial TV (DVB-T), analog radio, in Frequency Modulation (FM), in Medium Wave (MW) and Short Wave (SW), at international, national, regional and local levels; terrestrial digital radio (DAB-T); satellite analog and digital TV (DVB-S) via Hot Bird 1 and 2; Isoradio FM service in isofrequency (103.3 MHz) for drivers
4 Transport requirements of broadcasters TV contribution and distribution networks Contribution: transport of high-quality video/audio streams (mainly real-time) between different sites (Regional Sites, Production Centres, etc.) Point-to-point or point-to-multipoint Frequent network re-configurations Variable source and destination points High video quality and network reliability Low latency Primary distribution: transport of TV and radio programs to all the primary Broadcasting Centres National or regional coverage One source / many destinations Non-stop transmission Fixed network configuration
5 Rai Way transmission networks logical functions PRODUCTION CENTRES AND REGIONAL SITES FOREIGN COUNTRIES RAI WAY transmission network MOBILE LINKS DIRECT TO HOME BROADCASTING TRANSMITTERS Service through Rai Way terrestrial network

7 Rai Way Objectives Efficiency enhancements and cost reduction Centralize the supervision Improve the service provisioning Fault Management Consistent and aligned network inventory Network circuits planning and configuration
8 Convergence between objectives and tecnology The Rai Way Transport Network uses many different equipments: SDH Radio links by Siemens and Alcatel ADM by Marconi (SMA family) and Alcatel Cross Connect by Siemens Video codec by Alcatel and video matrix by Probel RaiWay has implemented an INMS system Integrated Network Management System for integrating different vendor Element Managers (mainly by Alcatel and Siemens) Developed by HP and based on architecture based on TMN reccomended standards for Network and service level
9 INMS Solution One of the projects realized for RAIWAY by HP is INMS, a custom solution based on Open View TeMIP. Through INMS, RaiWay gained a system capable of automated provisioning on different brands of SDH network equipment for broadcast circuits. The flexibility of this solution allows also RAIWAY to optimize the usage of its network, especially with the ASI and Ethernet circuits, without having to make big investment in new network equipment and technologies. Moreover INMS gives a complete picture of the network features, with the fault management functionalities TeMIP Service Management System GUI SMS DB Network Manager SDH NM SIEMENS OSI AM SIEMENS EA-MAPPER INMS 3.*

12 INMS Functional Areas Configuration management The system has an aligned and consistent knowledge of the network data and determines its configuration in terms of connectivity and payload tributaries. Services provisioning and activation INMS manages the SDH network, providing adjustments of quick and up-to-date algorithms for calculation and delivery processes Fault management and services correlation Physical and logical resource alarms are collected and displayed. The related impacts to the circuits are determined and the proper root cause analysis is also performed and reported.

15 Asi and Ethernet port management To manage an Asi or ethernet port is necessary: Add/Remove bandwidth (add/remove virtual VCn to/from vcgroup) to a Physical port (multitechonologyttpbid object) Create/Delete Cross Connection between the n concatenated vcnttpbid and the tunctpbidirectional, can be unidirectional or Broadcast Control path activation Path Activation of all the paths involved in virtual concatenation path (this permit to enable/disable the paths after the creation)
16 INMS concurrent provisioning Performance issues The very particular context of broadcasting, where dynamic lifecycle and unidirectional broadcast services are required, determines the intrinsic distinction of services provided by broadcasting players respect to the traditional phone bidirectional services. Performance became a critical issue specially for VCAT circuit, where a massive interaction with the network is foreseen Concurrent provisioning INMS achieves satisfactory results realizing the concurrent and parallel provisioning by means a TeMIP multi threading architecture INMS Req. Req. Req. ADM1 ADM2 ADMn 1. In order to optimaze the set up time, INMS interacts with the network in parallel mode 2. Responses are collected by INMS and the setup time depends on the slowest device
17 Simplicity INMS Result & Benefits Circuit configuration and activation are now automatic Agility Custom-developed graphical user interface makes operators jobs much easier and faster RAI Way can deliver appropriate service levels in terms of quality and timeliness INMS enables Rai Way to provide NG-SDH service (ASI & Ethernet) Added Value INMS enables RAI Way to deploy SDH network equipment from different vendors promoting a competitive scenario and enabling RAI Way to realize cost savings Customer satisfaction levels have improved markedly
