Media Gateway Development Challenges
4
Operator Needs

• Connectivity between the different networks
• Mobile
• IP
• PSTN
• Cross-network integrated services
• Voice/video mail
• Video portal
• Multimedia server
• Recording
• All applications must support mobile-to-packet,
  packet-to-packet, and TDM-to-packet

5
Operator Needs

• Video deployment demands are still relatively
  small compared to voice deployment
• Flexible channel media type assignment is
  required
• Price and ROI
• Smooth and flexible migration from voice systems
  to voice and video systems
• Simple, synchronized, and balanced systems

6
Media Gateway Development Challenges

• Growing number of codecs
• Interoperability
• Quality issues due to environmental changes
• DSP code optimization
• Application-specific optimization
• System bottlenecks
• New hardware standards

Buying Boards or Chips

• Why Boards?

• Why Chips?

• Pre-requisite
• Standard form factor or
• Standard mezzanine-card connector
• Lowest risk
• Lowest initial investment
• Cheapest solution in the long run
• Negotiation
• Change vendor
• Easiest migration path to next generation DSPs

• Proprietary form factor
• Single-DSP solutions
• Very high volumes (10K)

Prediction By 2008 all new Tier-I
infrastructure solutions will be based on
standard boards and modules that are made by
third parties.
10
New Hardware Standards
11
Why Put Voice Video on the Same Chip/Module?

• Easy migration path from 0 video / 100 voice to
  100 video / 0 voice or any other usage model
• Lower system delay -gt higher overall quality
• No need to separate voice from video and send
  each to a separate chip/module
• Easier to establish lip-sync between voice and
  video when packets are lost or delayed
• Lower operational expenses
• Only need to support one chip/board
• Lower integration efforts
• Single API for voice and video
• No need for an aggregation device to
  combine/split voice and video

12
Why Run 3G-324M (H.223) on the DSP and not on
the Host ?

• Lower delay ? higher overall quality gateways
• Same DSP runs 3G-324M, voice transcoding, video
  transcoding and sends voice/video RTP directly to
  IP network
• Scalability
• When H.223 is running on the DSP, Host processor
  performance is not a limiting factor for moving
  to higher densitiesjust add more DSPs/boards
• Lower operational expenses
• Less components in the system. No need for
• DSP board/module for voice transcoding
• DSP board/module for video transcoding
• Controller module/board for 3G-324M

13
Media Gateway Development Challenges

• A typical Media Gateway is composed of four
  components
• Media processing DSP code
• Host-based state machines and APIs
• Hardware platform
• Media gateway application

• Generic

• Generic

• Generic

• Application-Specific

All generic components are provided by Surf,
allowing our customers to focus their resources
on the application specific part.
