Traditional Optical Network Architecture



Manual configuration - inefficient usage of the network
resource and slow service turn up time
IP & transport networks managed separately - not cost
effective nor efficient for planning or managing
changes
Lack of open standards/ interoperability – does not
allow carriers to leverage multiple vendors for best of
breed solutions
As a result, it is evident that carriers require
solutions over unified control plane across IP and
optical layer
OIF History


Founded in 1998, OIF is an open forum focused on
accelerating the deployment of next generation
optical interworking networks
OIF provides a venue for equipment manufacturers,
users, carriers and service providers to work
together to
•
•
develop key specifications to ensure the
interoperability of optical networks
resolve deployment issues

User Network Interface (UNI) 1.0 Signaling
Specification
An interim UNI 1.0 public demo held at SuperComm
2001 proofed UNI interworking with over 25 vendors
on control plane and data plane
NNI Implementation Agreement for OFC 2003

Inter domain signaling
Inter domain OSPF/ISIS based routing
OIF UNI/NNI Network Reference Model


UNI (User-Network Interface) - a signaling mechanism
between clients and transport devices
NNI - communication and signaling method among
optical domains in the optical core network (intra carrier,
inter domain)
