Section 2 Why Virtela a global network solutions company www. virtela. net | +1. 720. 475. 4445 8

Networking Regional Trends An Increase in Country to Country Interconnectivity the Last 5 Years—More Fiber in Place ü ü Peering between providers can still be an issue impacting performance Per Mbps cost decreasing, but still significantly higher than Europe & U. S. Availability and Enterprise Use of Alternative Access Technologies Such as DSL and Ethernet VPN Technology Maturity and Cost Savings Resulting In Augmentation/Replacement of Frame and Private Line Bottom Line: Globalization of the Enterprise is Driving Significant Increases in Bandwidth to/from Asia Pacific ü This drives ongoing infrastructure investment and enhancement a global network solutions company www. virtela. net | +1. 720. 475. 4445 9

“Do It Yourself” Pitfalls Failure to Execute On Contract Specifics with Regards to Terms and Conditions Across All Providers Best-of-Breed Infrastructures are Local/Regional—Not Global Broadband Attractive But Availability and Performance Questionable Unaware of Country-Specific Idiosyncrasies a global network solutions company www. virtela. net | +1. 720. 475. 4445 10

1. Negotiating Specific Terms And Conditions Multiple Vendors Will Mean Divergent Terms ü The only guarantee of uniformity is a single source Negotiate for Favorable Contract Terms ü ü Try to negotiate single/preferred currency for all sites—not always possible Specifically request to be billed monthly via an invoice • ü Many providers will push wire transfers (1 yrs payment upfront) or credit card Be aware of auto-renewal policies and keep track (will vary by circuit turn-up and provider) Document Service Delivery Parameters ü Confirm procurement responsibilities for all necessary devices • ü Provider installation techs typically very specific in their roles (i. e. , one tech for Internet access turn-up and another for VPN installation) • ü May consider purchasing locally—note that interface types will vary by country Consider contracting with a field service vendor with required footprint—define a Method of Procedure Request a project manager. If you have no local staff, also have someone from your team available 24 x 7 to manage/speak with your vendors a global network solutions company www. virtela. net | +1. 720. 475. 4445 11

1. Negotiating Specific Terms And Conditions Minimize Multi-Vendor Management Challenges ü Request that trouble ticketing and escalation procedures (names & contact info) be clearly defined within every contract ü Consider contracting with a language line service to deal with communication barriers— contract on a per usage basis Negotiate SLAs & Credits ü ü SLAs from local ISPs can be very hard to come by Do the math—and negotiate towards suitable credits particularly for critical outages Bottom Line: Don’t Leave Contracts to the Lawyers—I. T. Department Needs to be Intimately Involved a global network solutions company www. virtela. net | +1. 720. 475. 4445 12

2. Local To Global Performance There is No “Silver Bullet” Global Infrastructure Singly Owned ü Provider ‘A’ may be “best-of-breed” in Thailand but not necessarily in India or China—for true best-of-breed you will have to stitch it together yourself • ü Considering performance, price and service availability Even the best networks will have issues—guaranteed. For critical offices explore your disaster recovery alternatives (diverse alternative access methods, etc. ) End-to-End SLA’s Are Difficult, If Not Impossible as a “DIY” ü ü You will not get end-to-end SLAs between sites served by different providers Regional providers will guarantee in region, but no help from Asia Pacific to Europe or U. S. Critical to Know How Providers Interconnect and Route Traffic ü Peering between many local Asia Pacific ISPs still happens in the U. S. • ü ü Potential for severe latency and packet loss issues It is critical to know your application thresholds or breaking points—in particular, packet loss There are now often multiple provider options in a country—look beyond the incumbent a global network solutions company www. virtela. net | +1. 720. 475. 4445 13

3. “Business” Grade Broadband Seriously Consider Broadband—But Do Your Homework ü Providers often have many products differentiated by their contention ratios (oversubscription: 50: 1, 1: 1)—watch what you buy ü If VPN being used you want a static IP—many providers do not offer ü Identify who will provide the DSL router—you may need to procure your own ü Confirm that there is 24 x 7 support—this is not always true In-Country Providers Unlikely to Guarantee Performance ü ü Some will guarantee bandwidth, but cannot guarantee performance site-to-site Again, peering points critical—do not want to go through U. S. to go from Thailand to China • • ü You also do not want to depend on a single congested peering point between two providers/countries Can cause wide, unpredictable swings in DSL performance Look for “optimized” and diverse in-region routing capabilities • Shortest path not always best path either a global network solutions company www. virtela. net | +1. 720. 475. 4445 14

4. Country-Specific Idiosyncrasies Become Familiar with Local Infrastructures Government Firewalls (e. g. , China) ü ü When you buy an IP connection in this scenario it may work and then it may not In many cases, can direct connect to an alternative provider private network and backhaul to a point outside of the country (requires a POP). • China example: Backhaul from mainland to Hong Kong and then out—significantly improved performance Government Gateways (e. g. , Saudia Arabia) ü In this scenario there are limited outbound connections to only certain government approved providers—they determine how traffic is routed/handed off • ü You therefore have no performance predictability not having the same provider on each side Your only improvement option is the ability to best-path route your specific traffic Compression On Traffic Leaving the Country (e. g. , India) ü Bandwidth cost within country very different than leaving the country—same with performance ü You can buy cheaper bandwidth compressed 4: 1, etc. —typically not an issue in-country, but severe performance impacts on congested links living the country a global network solutions company www. virtela. net | +1. 720. 475. 4445 15

Summary Details Matter When You are Operating Half-Way Around the World There are Alternatives to Incumbents and the Status Quo Broadband is a Legitimate Alternative Virtela’s Business is Taking On these Pitfalls—Benefiting Virtela Customers ü Virtela’s proprietary IP Service Fabric (IPSFsm) multi-connects its customers to the best regional and global infrastructures around the world ü Our power is in the ability to quickly and seamlessly move traffic from one of these underlying backbones to another a global network solutions company www. virtela. net | +1. 720. 475. 4445 16

Section 3 QOS and MPLS a global network solutions company www. virtela. net | +1. 720. 475. 4445 17

Role Of Qo. S – What Should You Demand? “Performance” is Important ü We have customers running IP video and Vo. IP with Qo. S and others without ü Have customers running Vo. IP over broadband internationally Business Drivers are Always Present ü Cost, delivery timeframes, technology availability, etc. Some Realities… ü We Connect to Backbones Around the World…They’re Overbuilt & Under Utilized (IP, MPLS, etc. ) ü Regardless of MPLS it’s Still About How the Carrier Operates the Network • We see MPLS networks that don’t perform to the levels of IP networks in the same region ü Last Mile is Still the Key ü What About Broadband (DSL & Cable)? a global network solutions company www. virtela. net | +1. 720. 475. 4445 18

So MPLS Is The Way To Go You’re Tied to One Provider ü No flexibility to choose technology & provider by location ü MPLS Co. S does not transfer between carriers Who is the Best Provider? …What Defines Best? ü Is it price? ü Is it single source…one throat to choke? ü Is it best performing network infrastructure by city, by country? • Provider ‘A’ may be “best-of-breed” in Thailand but not necessarily in U. S. or China a global network solutions company www. virtela. net | +1. 720. 475. 4445 19

Summary Always a Healthy Dose of Reality Incorporating Business Requirements ü There are business, availability, and interoperability constraints to consider re: MPLS everywhere ü Then again, DSL is not a T-1 It’s About Performance for Your Environment ü Not MPLS or COS, etc. ü What are the requirements versus assuming…why overbuild & overpay What’s the Provider’s Role in Qo. S? ü It’s critical & it’s end-to-end (LAN through WAN…the application) a global network solutions company www. virtela. net | +1. 720. 475. 4445 20
