Some Observations

VoIP has gone Mainstream

VoIP is enabling the Best of Breed

• In the past, one vendor controlled all the technology

o “You can have any color phone you want, as long as it’s black”

• Going forwardo Softswitches, IP-PBX, Messaging, IVR…o Standard protocols and hardware platformso VARs and Systems Integrator are choosing

the best hardware and software for their application

o Creating value and products that fit needs

What is the difference?

This one has enhanced services

Increasing Density

• Moore’s law will continue to increase density (more functionality for less money)

o CISCo DSP o Packet Processors

• Shifting the role of dedicated hardware

Emergence of New Blade Form Factors

• ATCAo Advanced Telecom

Computing Architecture o 140 sq. incheso 200 W of power/blade

• AMCo ATCA Mezzanine Card

• PCIExpresso Desktop and Enterprise

New Form Factors

• “Blade” Servers• IBM, Intel, Dell, Compaq, etc.• Very high computational density• Ideal platform for hosting applications • Proprietary, but “Open” form factor• Standard peripheral form factor

o Usually PCI

IBM BladeCenter

Death of the PCI Driver

PCIDriver

• Replaced by on-board protocols

On-board Protocols

• On-board protocols are becoming the preferred control mechanism

• Using a standard or proprietary protocol to control a board or stand-alone deviceo SIP, VoiceXML, MSCML, MGCP

• Displacing the traditional API/Driver model

• No more PCI drivers!• Eliminates O/S dependence • Bonus: Better test tools (Ethereal)

Adoption of Blades vs. Boxes

• Software developers love distributed architecture using standard protocols

• Product Managers and Integrators have different challenges:o Cost Targetso Offering communications “solutions”o Branding issueso Fewer boxes

• Result:o PM & Integrators many times prefer

blades

One Code Base

• Today, many application developers are supporting two separate code bases:o One for TDM implementationso Second for VoIP interfaces

• Challengeso Maintenanceo Testingo Surrounding Management Softwareo Expertise on Boards and APIs

One Code Base

• Mass movement to supporting only VoIPo SIP, H.323, MGCP…

• Using gateways to connect into TDM applications

• Why?o Only maintaining one code baseo Saves engineering resourceso Focus on the application, not the plumbingo Eliminates management of TDM interfaceso No driverso No O/S dependencies

Need for Transcoding

• Wireline and wireless carrier depend on different voice compression formatso Different needs and limitationso G.729a favorite with wireline carrierso AMR or EVRC for wireless

• How to interconnect?o Transcoding Resourceso High Densityo Low Latencyo Excellent voice quality

Transcoding

Focus on Security

Cable systems are the early adopters(multi-drop nature of cable systems)

• Call control Encryptiono IPSec and BTNS

• Voice Path Encryptiono SRTP

• Management Interfaceso HTTPS

• Customers will demand that equipment vendors will support new security standards

Focus on Security

• Session Border Controller• Protecting your network / IP-PBX

from intruderso Network Isolation / Protectiono Encryption / Privacyo Protect against Denial of Service

Attackso Stand-alone devices (for now)

• What’s next:o Built-in to IP-PBX at the

Enterprise

The Last Mile

Carriers are depending on the existing broadband facility to the Enterprise/Consumer

Voice Quality

• Greater dependence on existing IP infrastructure (Cable, DSL, T1, Wireless)

• Requires that equipment that can operate in “suspect” network performance.

• Dependence on low bit rate coders by carriers is increasingo More through the same pipeo Less congestion = less lost packetso Better voice quality

• More on this in a separate session

What to worry about

• Taxationo With the shift to VoIP, taxation

model will have to change.o Governments will need revenueo We need to guide their decisions

• E911o The solution is understoodo Can carriers react quick enough?o What other similar “legacy”

issues await?o Is there a better way?

• Will wireline phones really matter?

Moving Forward

pays the best interest.” Benjamin Franklin
