What is Active Optical Network (AON)? 

 Mikhail Popov 

7 th Concertation Feb 2010

Home run (AON)

 – Point to point

 – High bandwidth

 – High flexibility

 – Most deployed in Europe

Active star (AON)

 –High bandwidth

 –High flexibility

 –Most deployed in Europe

and in AT&T areas in US

Passive optical networks (PON)

 –Passive network with

tree topology

 –Average bandwidth –Most deployed in Asia and

Verizon areas of USA

 –Some deployments in Europe

How to manage all that?  Control and management candidates:

Distributed control - e.g. IP, (G)MPLS, xSTP, OSPF, BGP

Centralized management - e.g. NMS/OSS, Path Computation Element

(PCE) Hybrids, e.g., GMPLS + PCE

ALPHA focus: Hybrid GMPLS / PCE multi-layer Ethernet  C  on

How it helps?  Traffic engineering:

path control

bandwidth reservation prioritization...

Adds or enhances resilience functions

 

Core

Aggregation

 Mikhail Popov 

7 th Concertation Feb 2010

Possible OpEx and CapEx savings, e.g.:− Self-configuring networks – all domains

− Simplified migration

− Simple and flexible designs

Will bandwidth, energy efficiency and traffic dynamics requirements lead tothe inclusion of a dynamic optical layer?
