1 Sourcing the WAN One or Many? (Enterprise Case Study) Taki Remtulla CTO & Partner at ABILITA New York, April 2014

2 Two Enterprise Case Studies Major Oil Company in the Middle East & Financial Ins9tu9on in North America Oil Company: from One Global carrier to 5 Regional Carriers Credit Union: from 4 Service Providers to one Global Carrier There is no One Size Fit All solu9on Examine the Network Before and AOer Redesign RFP Process and Carrier Evalua9on Implementa9on and Benefits 2

3 Before Redesign Oil Company HQ in Saudi Arabia with offices in Middle East, Asia, China, Europe and North America (15 countries) Circuit Types: IPLC over satellite links and FR & ATM in the distribu9on network Applica9ons: Voice, Data and video Data Centers: Dhahran (SA), Houston and Leiden (NL) Carrier: Saudi Telecom Challenges: Single point of failure (One Interna9onal Gateway), Limited NNIs with carriers, Long circuit lead 9me, no ac9ve development of new enhanced services Not easily scalable, SLA non- enforceable, trouble shoo9ng nightmare, MTR unpredictable, 3

4 Oil Company LocaOons 4

5 Before Redesign Credit Union 4 HQ Loca9ons and 70 sites from East to West coast HQ sites: New York; Bal9more; Denver, Portland Circuit Types: Point to Point PLC, Frame Relay, ATM and IP VPN across the public internet Network Topology: Hub and spoke in the regions and IP VPN between the HQs and data center in Denver Carrier: 4 providers for the four HQ loca9ons & branches Challenges: High Packet loss, latency and jiber across the public internet used for inter- connec9ng 4 Islands of carriers networking technologies Varied network performance, 4 network monitoring tools, limited visibility, trouble shoo9ng mul9ple carriers 5

6 Four CU LocaOons 6

7 Network Redesign OIL Company Oil strategic resource in poli9cally very sensi9ve area- the Gulf Most Cri9cal Factor: Physical Diverse routes from the country to the interna9onal offices in USA, Asia and Europe Architected 3 Interna9onal Gateways: Riyadh (Central) satellite to USA & Europe, Jeddah (West) to Europe over SEA- ME- WE cable through Red Sea and Dhahran (East) over FLAG cable through the Gulf to Asia and China Established 4 hubs to aggregate regional traffic: Dubai (Gulf & India), Singapore (SE Asia and China), London (Europe) and Houston (North America) Designed fully meshed IPLC between the 4 hubs; each hub had three alterna9ve routes paths Regional distribu9on network for the smaller sites 7

8 Diverse InternaOonal Routes 8

9 Network Redesign Credit Union Most cri9cal requirement for the 4 merged CUs: Consolidate their WAN & IT infrastructure A single unified networking plagorm, any to any connec9vity, end to end encryp9on, scalability in bandwidth and loca9ons; Five CoS, visibility & control to set policies, stringent and uniform SLAs, auto failure to back up circuits High footprint and resiliency in the respec9ve regions Full Diversity at the four HQs: CE + MH+ CO + POP + PE Man Hole Serving CO1 POP1 CE Customer Site Man Hole Diverse Access Serving CO2 Transport / Broadband Network PE PE POP2 9

10 RFP and Carrier EvaluaOon The key to successful procurement strategy: a clear understanding of client specifica9ons including loca9ons, bandwidth, diversity, security, class of service, scalability, business con9nuity etc. Equally important success factor : evalua9on of Carrier capabili9es in terms provider's backbone carrying capacity, footprint, POP s and PE Router loca9ons, performance, CoS offerings, SLA, encryp9on, network management capacity Allowing carriers crea9ve solu9on Carrier intangible values : vendor stability, best of breed, not bleeding edge, solu9on simplicity, dependable service delivery Carrier Evalua9on: apples- to- apples comparison both technical and cost 10

11 ImplementaOon (Oil Company) Contracted 5 Carriers for each geographical region STC for Saudi Arabia, ETISALAT for Gulf & India, BT for Europe, SingTel for SE Asia & China and AT&T for North America Each carrier had superior footprint and robust network infrastructure in their respec9ve region Innova9ve, flexible, price compe99ve and invested resources customer care/rela9onship building Fully meshed IPLC between the 4 hubs and regional distribu9on network for the smaller sites Provided Highly diverse paths and resilient WAN Direct contact 5 Regional Carriers client job to manage service providers and not the network Substan9al cost savings - millions 11

12 ImplementaOon (Credit Union) Contracted One Carrier to provide one single unified MPLS based IP VPN networking plagorm to all the 4 CU regions Technical depth, understood client needs, large backbone carrying capacity, maximum footprint, sufficient diverse elements - CO, POP s and PE Router loca9ons Price Compe99ve proposed to pay early termina9on charges Complete solu9on: MPLS for all CUs, Carrier Ethernet for the Data Center, end to end encryp9on and auto failure Full network diversity at the 4 regional hubs & centralized NM Improved performance availability, latency, jiber, MTR COS allowed priori9za9on of voice, data and video traffic Substan9al Cost savings and enhanced WAN Infrastructure 12
