Making the Most of Your Investment in IP

1. Making the Most of Your Investment in IP Bernard Foot Product Marketing Manager, RM Lifelong Learning & HE

2. Things To Put On Your IP Network • SCSI • Fibre Channel • TV & Video • CCTV • Videoconferencing • Telephony • VGA • Projectors

3. TV & Video • We’re talking full broadcast-quality • MPEG-2 (video) + MP2 (audio) encoding • Multi-channel, multi-source, multi-destination • Any type of source device • Camera, VCR, DVD Player, live digital broadcast • Any type of receptor device • TV, VCR, DVD Recorder, PC, Projector • Video services • Storage • Editing • Scheduled playback • Video on demand

4. Why ? • Avoid implementation of another network • Your IP network already covers your campus • View on PCs as well as TV appliances • Video services • Topographical flexibility • Centralise … or distribute • Hardware consolidation … or avoid storage costs • Move appliances easily … or avoid moving them • Scalability • Lots of applications in education • Demos, time/space shifting, in-house TV stations, halls of residence, curriculum material, …

8. TV-over-IP: FAQs • How much bandwidth is needed? • Typically 4-6 Mbps per channel • Could be less; absolute max. of 14Mbps • Multicast; delivered only on request • Does this reduce TV licensing costs? • No. Each viewing device must be licensed. • (If it can receive public broadcast material) • Is it expensive? • No. You can get going for £2-3K

10. CCTV-over-IP

11. Use of CCTV in Education IrritationsRisks Petty theft Burglary/robbery Vandalism Arson Graffiti Unauthorised access Bad behaviour Bullying • Impact of DPA on use of CCTV • Cannot focus on individuals • Cannot give out material (exc. to police) • www.informationcommissioner.gov.uk/eventual.aspx?id=5739

12. Why CCTV-over-IP ? • Avoid implementation of another network • Storage & Processing services • Topographical flexibility • Manage from anywhere • 3rd party service providers • Staff on the move (PDAs, laptops, …) • Centralised multisite management (e.g. outreach centres) • Simplicity of connection • Move appliances to where they’re needed • Scalability • Low-cost devices • Integration possibilities

13. CCTV-over-IP: FAQs • How much bandwidth is needed? • How much have you got? • Depends on resolution, frame rate, compression • Typical: 200 Kbps-2 Mbps; could be down to 20Kbps • What standards are used? • Motion JPEG (MJPEG) • Lower cost components • MPEG-4 • Slightly lower bandwidth (down to 5Kbps) • Where it’s all going • How much does it cost? • How much have you got? • Get started for under £1,000

17. Videoconferencing

18. VC Site B (H.320) VC Site A (H.320) MCU* MCU* ISDN Network VC Site C (H.320) MCU* * MCU = Multipoint Connection Unit (H.231) “Traditional” Videoconferencing

19. Problems with ISDN • Users have to have ISDN • Expensive to use • 1/2(n2-n) growth in connections for multi-site • Low speed (128 Kbps) • Can bond multiple channels • But also multiplies the cost • Channel bonding reduces reliability • Not “Always On” • Difficult to control/manage/monitor centrally • Not a Local-Area solution • Concept is wide-area, point-to-point, VC rooms

20. VC Room VC Room Personal (Desk-top) VC-over-IP (H.323 or SIP*) Broadband Internet Personal (Desk-top) VC-over-IP (H.323 or SIP*) The VC-over-IP Dream Group (Set-top) VC-over-IP (H.323 or SIP*) VC Room * SIP = Session Initiation Protocol (IETF)

21. So What’s the Problem ? • Bandwidth? • Not really - typically 128-768 Kbps per node • It’s Quality of Service • VC is Real-time & “inelastic” • QoS can be managed within a network … • … but QoS markers stripped at network boundaries • It’s Security • Dynamic port allocation is not firewall/NATS-friendly • Could use proxy or Application Level Gateway • No problems within your network … • Use PSTN gateway to go outside your network

24. Voice-over-IP (VoIP)

25. Why Do It ? • Use your existing network • Reduced call charges • Development not hampered by ITU, etc. • Software-based • Hardware does not become obsolete • Integration with other IT services • e.g. “follow me”, presence information, E-mail, AD • Low bandwidth usage • typically 2 x 20-100 Kbps per connection • Ovum - IP PBXs reach 50% penetration in 2007

26. Why Not Do It? • Investment in legacy telephony systems • So interface using Media Gateways • Does the other end have VoIP (e.g. 999 calls)? • Use Media gateways to interface with traditional telephony • Same issues as videoconferencing: • QoS • Security (firewalls, NAT) • Potential problems for inter-organisation calls • Same solutions as videoconferencing: • Proxies (Session Border Controllers) • Make use of encryption difficult • Add latency • May preclude use of new features • Media Gateways • No problems within your network • Use the Media Gateway to go remote

31. VGA-over-IP

32. Why ? • Make use of your existing network • Display on remote VGA-XGA devices • projectors, plasmas, etc. • not restricted by VGA distance limitations • uses any standard display device • from central location • without being there • avoids use & cost of wireless • output from any software • e.g. rolling presentations

33. VGA-over-IP VGA PC with client s/w to copy VGA output to IP The RM Ekko

34. Bandwidth Usage • Typical usage: • Average 1Mbps • Bursts of 5-10 Mbps • Complex Images/Photographs • Bursts of 30Mbps • Continual animation or video • 30 Mbps

35. Possible Futures • Multiple Ekkos controlled by single PC • Full-quality video • Attach kbd & mouse => thin client
