OIF overview OIF Worldwide interoperability demo 2005

• Introduction• Some technical details• OIF & ITU collaboration• Telecom Italia Laboratory in Torino

Conclusions

A brief history Traditional networks limit the ability to offer new data-centric

services in a cost and resource efficient manner• Time and labor-intensive inventory and provisioning processes • Limited service levels, protection schemes, service differentiation

OIF UNI/E-NNI enables the efficient deployment of these new services

• Rapid, flexible provisioning• Multi-vendor interoperability

Keys to ongoing success• Joint carrier / vendor participation • Liaisons between standards organizations

Domains can be advertised as• Multiple exposed border

nodes with virtual intra-domain links (vendor 1) or

• Single abstract node (vendor 2)

User-Network Interface (UNI): signaling interface for clients to request services from optical network

External Network-Network Interface (E-NNI): signaling and routing interface providing call/connection control and topology

Domain edges provide interworking between vendor-specific Internal NNI (I-NNI) and OIF UNI-N/E-NNI protocols

Ethernet EthernetSONET/SDH

Ethernet over SONET/SDH adaptation using GFP/VCAT/LCAS Ethernet Private Line Service (E-Line Service Type) triggered by UNI

connection requests Services enabled by data plane VLAN tags

• Ethernet Virtual Private Line (E-Line Service Type)• Virtual Private LAN (E-LAN Service Type)• Internet Access/Virtual Trunking (E-Line service type with multiplexed

access)

Major Accomplishments

Multi-layer call/connection control of UNI-N devices• Orchestrates actions between client and server layers• Controls Ethernet adaptation using GFP-F/VCAT/LCAS

Creation of end-end calls and connections across:• Multiple data plane layers• Multiple vendors’ equipment• Multiple carrier labs

The major features (1) Ethernet over SONET/SDH adaptation and (2) distributed optical control planes have each been demonstrated before• However, this is the first event bringing both together

in an integrated fashion on a global scale

Interoperability: Carrier Benefits

Provision end-to-end dynamic connections for flexible data services over multiple, control plane enabled SDH/SONET domains

Deploy at faster pace innovative network technologies

Select cost effective and leading edge network elements, platforms and multi-vendor solutions

Reduce operations overheads and simplify provisioning of new services

OIF and ITU-T Collaboration

Promotes the global development of optical internetworking products

Recognized by ITU-T

Study Group 15 is the focal point for studies on optical and other transport networks, systems and equipment.

• Carrier Requirements• Interoperability Experience• Protocol Specifications in OIF
