Telecom Fiji MPLS Network Case Study

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

Last Mile Access

Ø Fibre o Spur Links o  Metro Ring

Ø Copper o SHDSL o  ADSL o DDN

Ø Radio

Services on MPLS

•  L2VPN o Customer manage their own routes o Point-to-point connection

•  L3VPN o  Routes also manage by Service Provider o Cloud service within Customer network o Easy to deploy and very scalable

•  VPLS o  Layer 2 Mesh Connection o Extend LAN to more than 2 sites

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

Thank You!
