Introduction
• Telecom Fiji Introduces MPLS network back in 2008
• Planning & Design – 2008 • Proof of Concept (PoC), Acceptance Test -
2009 • MPLS Training – 2009 • Installation & Final testing – late 2009 • Test MPLS service on Telecom Fiji WAN – 2009 • Commissioned 1st Cooperate Customer – 2010

Legacy Network Transformation
• Technology Trend for Telecom Fiji – Analogue – early days – PDMX - 1987 – X25 (Packet switching WAN) – 1991 – Digital Data Network (DDN) – 1992 – Frame Relay - 1997
• Features & Limitations – Maximum Speed – 2Mbps – Interfaces - X21, V.24 or RS232, V.35 and G.703 – TDM Network

Why MPLS?
• Bandwidth demand o up to 100Mbps for Metro Services o Up to 50Mbps IPVPN
• Easy deployment and Management • Customers can view their link performance • Monitor End-to-end services • Proactive to faults

MPLS Core • P Routers - 3 • PE Routers – 16 (one in each town) • Aggregate Switches – 16 (mostly one in
each town) • Provisioning tool for Service Provisioning • Management tool for real-tile monitoring. • ACS tool for secure access of all MPLS
equipments. • VPN service for remote login

Challenges
Ø L3VPN Service. o Exchange routes with customer o Who will provide PE – CE ip address? o Routing protocol used.
Ø L2VPN Service o Vlans exhaust o Multiple L2VPN connection to HUB site

Challenges Cont…
Ø Misunderstanding of network requirements with Sales people & also from Customer.
Ø Migration from Legacy DDN to MPLS due: o Resistance to change o Interface change from X.21 to Ethernet o Concept change

Results & Outcomes
• Most customers are using MPLS in Fiji because of: o High Speed capacity o Scalable o Network layer (routers) are now provided and
managed by Service providers. o Upgrades done in minutes o Flexibility to offer other services such as
dedicated Internet, VoIP…etc o Simple Integration to IP_PBX
