4 Schools Network Overview Free ‘always on’ broadband connectivity to Schools 3 Year Agreement –Dept of Education/Dept of Communication/TIF 3,925+ Schools 6 Access Providers HEAnet backbone network Onward connectivity to Internet & Educational Networks HEAnet Managed Services: Network; Security; E-Mail 1 st Line NCTE Service Desk & 2 nd Line HEAnet Schools NOC

5 Responsibility Areas

6 Dept of Education Access Tender Evaluation HEAnet Technical Advisors to DES/DCMNR Strong response to Call for Tender Evaluation by Evaluation Team over Sept-Dec 2004 Evaluation of 100+ broadband service offerings Evaluation of 80+ different router offerings Report to Ministers - Christmas 2004 Decision by Ministers – 5 th January 2005



9 Schools Network Bandwidth

10 Phased Availability of Services INITIAL SERVICES IP Connectivity between Schools IP Connectivity to the general Internet Educational/Research Networks Access Network Security Content Filtering Web-based E-mail DNS 2 nd Line Support to NCTE Service Desk LATER SERVICES Web Hosting Personal disk space Video Conferencing Video Streaming Video Lecture E-Schoolbag Content Hosting

11 Project Management Approach

12 Project Planning – dependent on Access Tender Project Financials – dependent on Access Tender Project Initiation Document –(scope, constraints & exclusions) Risk Register Resource Planning: –Dedicated Schools Team –Cross-HEAnet Consultancy –External Consultancy Project Organisation

15 Network Design Network Topology Access Network POP Layout Layout and Routing IP Scheme

16 Schools Network Topology

17 Access Network Principles Layer 2 service from Access Providers PPPoE over L2TP, VLANs & ATM VC’s RADIUS authentication Managed Router in schools (Cisco 871) Public (HEAnet) IP addresses IPv6 & Multicast (later services)

18 Access Provider Aggregation Overview

19 Sample ADSL Service

20 Sample Satellite Service

21 Schools’ PoP Layout

22 Layout and Routing Only links and loopbacks go into OSPF Everything else is redistributed straight into BGP Each PoP provides the other with transit over the National Backbone Extension Onward connectivity provided by BGP connection to HEAnet core

23 Very Large Post-Primary (>1000)/23 (510) Large Post-Primary (500-999)/24 (254) Medium Post-Primary (100-499)/25 (126) Small Post-Primary (<100)/26 (62) Large Primary (500-999)/24 (254) Medium Primary (100-499)/25 (126) Small Primary (50-99)/27 (30) Very Small Primary (<50)/27 (30) IP Addressing

24 Network Management Systems

25 HEAnet: Centralised Network Services  Monitor schools’ connectivity  Generation of intelligent alerts  Monitor services  Graph network usage  Capacity planning  Access Provider measurements vs. SLAs: –Latency (RTTs) –Packet loss –Network availability

26 SmokePing Nagios Cricket

27 Geographical Network Map


29 Provisioning Systems

30 Provisioning system - overview Required to generate school specific configurations for CPE router, monitoring, etc. Dynamically provision services Database backend with schools’ information Informational web front-end

31 Provisioning System – services provisioned CPE router config Nagios Radius Cricket Cisco ACS Smokeping Fortinet Maps DNS

32 Provisioning System Structure

33 Security Design

34 Schools Network Security Design

35 Centralised Content Filtering DES Requirement Fortinet solution Security node at each PoP 500Mbps capable “in-line checking” High Availability & ASIC technology Content filtering capability: –In-Line Anti-Virus blocking –White List –Black List –56 Categories –Database of 28 million rated URLs –24x7 Managed Service Intrusion Detection/Protection System (IDS/IPS) “Security Profiles” set by Dept of Education

36 Kilcarbery Centralised Security

37 E-Mail Services

38 Schools E-Mail Service DES Requirement Award to Sonas Innovation Web front end Opensource components LDAP foundation Anti-Spam & Anti-Virus blocking Calendar & Address list facility Autonomy at school level to administrate some email services (e.g. new mailboxes) Scalable to accommodate all staff & pupils Dept of Education set email policy

39 Scalability of Network Design /12 IP Address Space = over 1 million public IP addresses Email solution can accommodate 200,000 mailboxes, scalable up to 800,000 mailboxes Security solution scalable up to 4Gbps Cisco 871 new generation router

40 School Support Services

41 HEAnet Schools NOC Separate to main HEAnet NOC Different customer needs Separate processes 2 nd Line role Shared ticketing system with NCTE Separate contact channels
