1. TDM is past its prime Built primarily for voice, and adapted reasonably successfully for leased

lines, fine-grained TDM (PDH/SDH) is increasingly irrelevant for Next Generation Networks

TDM is also very expensive on a cost/Gbps basis

2. Packet transport is on the rise There is recognition that transport must focus on packets, not bits There are multiple approaches, and a lot of confusion out there

3. Interest in the Packets+Photons Phenomenon is growing There is also recognition that the worlds of packets and of optical

transport must come together Again, there are several approaches, and no clear way forward

What Should Be Done?What Should Be Done?

Scale

• Popular notion that convergence has happened is false. It only happened at the forwarding plane – not the control plane

Each service has diverse requirements (TE, QOS, security, growth rates)

Requires multiple control planes

Since today’s equipment only supports one control plane, Service Providers are forced to roll out multiple subnets, or risk compromising scale, stability and/or security

As more new services are introduced this leads to escalating CapEx and OpEx


Control plane multiplicity changes that dynamic and fulfils the true promise of convergence

• Shared infrastructure

• Services are decoupled from network

• New services can be introduced without building a new subnet

• Each services can be managed and controlled individually

• Service introduction is swift and with reduced risk

Each service now runs on its own “Virtual Service Network”

Lower CapEx, lower OpEx, Lower risk

Energy-Efficient Networking


1. Electricity costs rose 88% in US since 2003 (US EIA data) Intl Energy Outlook ’07 predicts doubling energy generation by 2030, mostly via increasing the use of fossilsEnergy has become a non-trivial OPEX item

2. Worldwide legislation changes and public support for energy efficiency and climate control

EMEA: reduce CO2 by 20% by 2020 UK: reduce CO2 by 20% by 2010 Japan: reduce CO2 to 6% under 1990 level by 2010

Carriers and businesses are setting new targets reduced energy consumption reduced heat dissipation reduced space requirements (volume footprint)

Why Care About Energy?


What Does This Mean for Data Networking?

Telecom facilities require power and cooling • Direct contributors to CO2 emission• The cost of energy and space will rise

Data networking is still a growth industry • Global connectivity relies massively on routing

and switching and this dependency increases• Significant increases in traffic are expected• This should NOT result in higher OPEX

► Vendors need to respond to the challenge


ECR InitiativeEnergy Consumption Rating

www.ecrinitiative.org


Energy-Efficient Routing Platforms – Basics Energy efficiency must be built into design

• Once the platform is designed and built, it is too late to speak of energy improvements

Consumed energy dissipates as heat • Heat is the major limit for building faster routers

Building energy-efficient routers goes well along building the fastest routers

Energy savings must be verifiable • Absolute energy consumption makes little sense• Energy should be normalized to capacity


Energy-efficient router – Definition Energy-efficient router is the one that needs the least amount of

energy (in joules) to transfer network data (in bits)

Energy Consumption of Router (ECR)

ECR = Σ C(i) T

C is the power rating of a router’s component i Є I, I is the set of configured components T is the router’s effective capacity (full-duplex)

ECR is normalized to Watts/10 Gbps Also we can use Energy Efficiency (EER), EER = 1 / ECR EER is expressed in Gigabits/KW


What can be done to improve energy metrics?

Today • Custom-designed silicon dies: No wasted blocks or gates

• Compare to commercial RISC CPU arrays (number of gates, clock)• Compare to off-the-shelf NPUs (effective speed per feature set)

• Find fastest and simplest solution possible to do the job• Use DRAM instead of power-hungry TCAM• Shut elements when not in use (lookup cores, SerDes and memory)

Tomorrow• Better integration, faster silicon and lower voltage• Use of MCM (multi-chip modules) to unite several chips• Possible use of CLI to monitor the real-time energy consumption


Energy Efficiency: Positive Impact

Energy efficiency is synergetic with higher speed • Efficient designs need fewer gates, allowing dense packaging• Less energy means less heat dissipation, easier to scale up• Promotes newer silicon fabrication technologies• Promotes novel software and hardware structures

Accelerated technology introduction• Promotes intensive scaling over extensive scaling (larger systems) • Shortens effective silicon lifecycle in production networks• Newer and better technologies deployed more frequently

Juniper Experience: Technology Into Energy

1) Small power overhead for packet operations- Fully custom in-house packet processors- Unique ASIC expertise, very high gate utilization

2) Highest Integration Levels – fabrication and packaging- Full 10 Gbps datapath on a single IP3 chip (includes lookup

engine, memory controller and fabric interface) - Up to four forwarding engines on one blade (MX960)- Industry’s only 100G/slot core router in commercial use (T1600)

3) Patented and Energy-Optimized Design- Stateless packet services without TCAM - Best-of-breed power converters


Synergy Between Vendors and Customers

Data networking is very mature now Many protocols and technologies were developed

• some are obsolete

But every time a network buildout is considered, it comes with a hefty list of features on RFP

Someone has to pay for all those features • Carved in silicon, unused gates and wasted power

Time to stop and think – • Which features are really needed and where?

Precise match of form and function is the best

Efficient network design is extremely important


Conclusions

Environmental impact and energy efficiency are verifiable• Choose right platforms to satisfy energy requirements • Use normalized ECR/EER metrics for comparison• Design networks to minimize the energy and rack space usage

We need to define and pursue aggressive energy goals• Reduced energy consumption• Reduced heat dissipation• Reduced space requirements (compact footprint)• This should be a joint effort between vendors, carriers and enterprises

Energy efficiency stimulates the industry• New designs will increase EER and decrease environmental footprint• Fast networking and energy efficiency are not conflicting goals

Convergence from many different perspectives

Services Convergence. Technology convergence.

• Optical and IP Topology / planes convergence.

• POP consolidation.• Reduction of network layers.

Networks convergence• Fixed and mobile.


IP & Optical Convergence


Transport IntelligenceSubstituting key SONET/SDH functions with G.709 and GMPLS Easy operations (OAM&P)

• G.709 overheads mimic SONET/SDH functions• GMPLS allows optical layer visibility into hard to detect failures• Integrated optics low-cost optical monitoring and provisioning

Fast protection• Integrated DWDM interfaces of a router enable fast triggers• Router-based fast reroute (FRR) may be more economical and as fast

and reliable as SONET/SDH ring-based protection

Sub-wavelength grooming• Not needed—router trunks can fill 10G/40G wavelengths• Manage bandwidth at the wavelength level using ROADMs

Replacing SONET/SDH functions by MPLS + G.709 + DWDM allows for a simpler, more scalable architecture
