What are we hearing?
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
Collaboration
Interoperability is key!

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?
11
– 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?

13
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
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
Traditional Video conferencing,
supported commercial vendors, expect
TIP to play increasing role
alongside SIP for interoperability
Exploring ways to
extend voice and
video calling
capability of
ENUM/UC in
Australia and Asia
to extend into
Europe & Brazil,

OVCC Challenges = learnings for R&E?
•
Sustainability - Reporting & Billing
–
–
–
•
Trust Fabric
–
–
•
–
–
•
–
•
–
–
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?
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
–
–
–
•
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
–
–
Complex Service/Platform integration
–
14
–
How can competitors work together
How much can be revealed for operational
success & value prop. For entire service?
Private routing with QoS
Private ENUM/SIP Proxy
Gatekeeper Proxy/Mesh federation
Capacity management
–
Session Management & control
–
–
–
•
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?
•
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
AARNet Copyright 2012
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)
E.164
PSTN
H.323
SIP
GDS/IP URL/IP
?
…
• Reuse existing infrastructure (DNS)
•
•
•
15
•
•
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)
ENUM
PSTN H.323
SIP

AARNet’s ENUM Plans
•
Use combination ENUM deployment
•
•
•
•
Register with NRENUM.net (+61
delegation)
•
•
16
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
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

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?

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-
