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

Aggregation

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?
