The Origins of ORCA
• The Technology and Operations (“TOPS”) Council
undertakes important strategic initiatives based on Board
direction to meet the industry’s long-term technology
needs and achieve member business objectives.
– The Unified Client Architecture Focus Group (UCA-FG)
was launched to assess tools that will enable software
developers to integrate core network capabilities into their
applications.
• UCA-FG considered opportunities for WebRTC clients to
access network functionality in a network-independent
manner.
• The UCA-FG’s work led to the creation of ORCA, or
Open Real-time Communications APIs.

Initial Focus WebRTC
7
Enhanced Device Capabilities
• A WebRTC-enabled web browser – on any device – has
the capability to deliver real-time audio and video.
– WebRTC (real time communication) enables real-time audio
and video as part of other web-based applications.
– Potential to enable new capabilities for communications
services:
• Customer interaction
• Conferencing
• Interactive sites
• Integration of voice/video
communications into a web environment
8
WebRTC Strategic Opportunity
• Proposed WebRTC services do not leverage network functionalities.
• Opportunity exists for WebRTC developers to connect to service
providers’ networks and leverage network services:
– QoS
– Security
E2E Quality of Experience
– Interoperation
Across Multiple Domains
– Reliability
– Routing infrastructure/
session control/presence
WebRTC specifies media handling for real-time communications,
but does not specify signaling for call setup.
9
Solution:
Open Real-time Communications API
• Provide developers with ability to
access network functions.
• JavaScript Library with APIs is
necessary to access and utilize network
services:
– Enables developers to more easily
develop applications and enhances
time-to-market
– Promotes service providers’ core
capabilities that may otherwise not be
leveraged
– Provides consistent access to network
functionality

• ORCA is an open source project hosted on GitHub.
– Individuals are free to join and contribute
• Client-side JavaScript is open source and royalty free.
– Links to network specific “transport libraries” at run time
• ORCA provides application developers with normalized
call control APIs.
– Can be extended to include additional APIs and JavaScript
libraries

17
ORCA: A Different Kind of Project
• ORCA is not a traditional standards project.
• Requires different skills:
– Contributions are actual code
– Must understand software development process
– Experience with Git
– Open source expertise
• Get involved in ORCA today

ORCA Testing and Support Requirements

ORCA API Testing
• Applications that use ORCA APIs will require
infrastructure to support testing and integration.
• Multiple levels of testing support are envisaged:
– Basic “reflector” to run in developer environment
– Test IMS environment
– Service Provider / Vendor developer programs
– Live network testing
• This presentation will discuss immediate requirements
for a basic “reflector”.
20
ORCA Testing: Basic Reflector
• Aim:
– Allow developers to test client implementations
– Run entirely within developer infrastructure
– Be available on GitHub to download by developers
• Not supported:
– High availability
– Scaling for multiple clients
– High performance
Provides first level test environment

Functions Supported
• The basic backend “reflector” will support:
– Register: allow client to register willingness to receive
WebRTC request
– Call: allow a second client to initiate a call to a previously
allocated client
– Reject: allow the registered client to reject the call request
– Accept: allow registered clients to accept the call request
– Disconnect: allow either party to terminate the call
– Event: notify the parties in the call of a change of status
(incoming call, call accept, call reject, disconnect etc.)
23
Future enhancements
•
•
•
•
PSTN: Enable calls to/from PSTN / PLMN
NAT / Firewalls: Support traversing of firewalls
Security: Provide authentication and authorisation
Robustness: Be highly available and scalable
24
Summary
• The basic backend “reflector” will allow application
developers to complete initial verification of applications
with ORCA functionality.
• Additional backend functionality will be made available
as required.

Device Solutions Initiative (DSI)
Overview

DSI Streamlines Network Innovation
Problem Statement
Integrating network-based service enablers such as call
signaling or network control requires developers to adapt
applications to use unique network APIs for each service
provider. Additionally, attracting application developers to
traditional standards is challenging - they primarily
contribute to open source projects.
Solution
The DSI provides a framework to support and develop
open source projects. Service provider and supplier
members work together with application developers to
provide client-side functionality that consistently exposes
core network capabilities into real-time communications
applications.

• But, developer rework is
required to accommodate

• The result:
– Developer avoidance
– Diluted scale
– Decreased utilization of

ATIS General Counsel
39
DSI Operating Procedures (OP)
• A draft of the OP that will govern DSI operations is
available.
• Approval of the OP will be one of the first orders of
business of the DSI membership.
• Objectives for DSI OP:
– Lightweight, flexible procedures
– Alternative IPR models to allow development of a broad range of
deliverables (including open source)
– A process for collaboration between DSI and the open source
community
40
Issues Addressed in the DSI Operating
Procedures
• Who can participate (Section 2)?
– Participation in the DSI is open to all ATIS Members, as well as to
other service providers, manufacturers, distributors and developers
of communications, entertainment and information technology
products/services
– DSI will collaborate with the open source community to allow for
developer input
• How are DSI decisions reached (Sections 5.3, 7)?
– DSI members will reach decisions via consensus; consensus is
reached when substantial agreement has been reached among
participants
41
Issues Addressed in the DSI Operating
Procedures
• How can new projects be launched (Section 5)?
– New projects are proposed in writing; DSI members approve new
projects via consensus.
• How will DSI be structured?
– While it is anticipated that work will generally be completed through
Project Management Committees (PMC), DSI members may
choose to establish subcommittees or task forces
– DSI and any subgroups will be led by Chairs/Vice Chairs (or CoChairs) elected by the DSI members
– Work will be completed via virtual or face-to-face meetings of PMCs
42
Issues Addressed in the DSI Operating
Procedures
• What types of deliverables can be developed (Section 6,
9)?
– DSI members will be able to choose to develop a variety of
deliverables, from open source software to standards
– At the initiation of a project, the DSI membership will determine
which of two intellectual property rights policies will apply to the
work:
1. A royalty-free IPR policy; or
2. A RAND policy based on ATIS’ established policy.
– The IPR policy governing a project will be established at the
initiation of a project via the consensus of the membership
43
Issues Addressed in the DSI Operating
Procedures
• How will DSI collaborate with the open source community
(Annex C)?
– Open source software developed by the DSI will be posted on an
appropriate open source repository
– Developers may provide feedback on the software
– Some developers (those demonstrating the appropriate skillsets)
may be invited to be part of the PMC, which can approve
submissions)
• Other issues that are addressed in the draft OP:
– Appeals Process (Section 12)
– Revision Process (Section 13)
– Due Process Considerations (meeting and election notices,
meeting notes, etc.) (Sections 4, 8, etc.)
