Collaboration Content Delivery Mobility

Customers are telling us that collaboration, content delivery and mobility services will help them extract more benefit from the core network – especially if they are user-friendly, scalable, redundant and secure

Interoperability is key!

Customer engagement

Concept Development


Current services environment• A complex ever changing environment

– Customers are free to use, compete own similar services– Complex customer environments exist – nationally/globally– Complex dynamic multi vendor market exists

• How to control, scale, leverage worldwide?– We all share good IP network baseline– Services tend to follow technical silos – efforts to converge underway– What is the value we bring to the customer?

• Greater zero cost call reach• Richer video call collaboration capability?• An infrastructure for third party service provider solutions?

– How to extend service access, reach, scale, secure– How to manage call control – coordinated efforts?– Can H.323/IP, SIP and ENUM play a role?– Single versus multi-vendor?– MCU scheduling and API support?

International ventures- best practice, influence, reach

Creating a video “cloud” of network carriers and managed video service providers to enable video to just work – coordination of dial plans, SIP, ENUM, access to MCUs, support and scheduling coordination, interoperability testing, apps development and worldwide access via commercial networks

Cisco TelePresence Exchange – investment in core infrastructure donated by Cisco to enable inter-inst. Collaborations nationally and globally

Traditional Video conferencing, supported commercial vendors, expect TIP to play increasing role alongside SIP for interoperability

Chairing efforts with the APAN community to add video network infrastructure to IP networks for no-cost video/UC call services to extend reach into Asia

Exploring ways to extend voice and video calling capability of ENUM/UC in Australia and Asia to extend into Europe & Brazil, ArgentinaN

OVCC Challenges = learnings for R&E?• Sustainability - Reporting & Billing

– CDR ingestion and analysis - homebrew– ROI on investment to carrier/customer is a

challenge, need to know locations of participants to determine travel/time/carbon savings via overlay portal

– How to bill? Carrier credits and chargeback to own customers?

• Trust Fabric– How can competitors work together– How much can be revealed for operational

success & value prop. For entire service?

• Session Management & control– Private routing with QoS– Private ENUM/SIP Proxy– Gatekeeper Proxy/Mesh federation

• Complex Service/Platform integration

– Multi-vendor compatibility with H.323/IP + SIP + Cisco TIP as opposed to single vendor cloud

– Skype integration and Microsoft/Lync positioning to track/respond?

– Social Media/IPTV/Video/Gaming integration – compelling IMS based blended services to track and position?

• Capacity management – Ad hoc dedicated meet me rooms – simple but

inefficient– Scheduling, API based multiple MCUs - physical

room mgt local control? – Network/MCU failure issues – do we/how to resolve?– Port utilisation differences – baseline min. stds?

• E2e support matters – managing changing environment, use of test beds/change mgt

– QoS & 24x7 test/monitoring facilities? – Need a separate test bed environment for tests and

coordinating upgrades?– Effort required should not be underestimated for

accreditation

• Security – best practice to secure key infrastructure

– Gatekeeper configurations– SIP security and use of ACLs?– Security behind SBCs ?

• Quality of user experience – Client software tied to BYOD – easier to code– Codec compression vs licencing costs

14


Why ENUM?• Converge reachability to provide true

unified communication, irrespective of protocols and call routing

• Route calls over existing (NREN) IP infrastructure (with PSTN interconnect for other customers/public)

• Reuse existing infrastructure (DNS)• Routing resilience• Reduced call routing complexity using DNS

lookup• Extend worldwide call routing by joining

nrenum.net alongside other private ENUM trees

• Enable rich media support• Low costs (hardware/support/training)• Allows ubiquitous move between technologies

15


AARNet’s ENUM Plans

• Use combination ENUM deployment• Sub-delegate to customer to manage

own number ranges/UC solutions (≈ infrastructure ENUM)

• User ENUM within AARNet and as a potential managed service

• Preference for central service

• Register with NRENUM.net (+61 delegation)• Free• VoIP/Video interconnect with 10+

other NREN worldwide supporting H.323 & SIP call routing + rich media + interconnect with “world” due to e164.arpa querying requirement = access to 40.000+ VoIP/video devices

Offer ENUM+ service by routing calls via AARNet SBCs to provide better •management, •monitoring, •support, •reporting, •security (first layer of protection, (DOS, malicious use, toll fraud), •lawful intercept compliance, •NAT traversal support, •Trusted IP addresses via firewall, etc.

Final thoughts• Why are we doing this? • Can’t we just use Skype? • Can’t the cloud solve this? • Can we interoperate + lower

costs? • From buy your own kit to

central?• Is the solution Multi-tenant

Infrastructure or application focus?

• How can we move forward?

• What is in it for me? Customer, Inst, NREN, vendor

• Facilitating collaboration for edu + research

• Not so simple (unmetered, $ svc, small grps)

• Possibly, but inst. Integration - calendar?• Needs national/global coordination• ROI vs $ + use issue

• Middle ground needed to route and offer user simple solutions

• Low hanging fruit? Buying club, targeted coordinated effort

• Customer – simple, multiple videotone experience and choices

• Inst - $ effective, low support, just works• NREN – value add, traffic use, great collab

cases, • Vendor – greater adoption and use,

interop/cloud experience, opportunities to grow/connect other sectors and inter-connect R&E with Govt, Industry etc18
