Networking Regional Trends
An Increase in Country to Country Interconnectivity the Last 5
Years—More Fiber in Place


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

This drives ongoing infrastructure investment and enhancement

“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

The only guarantee of uniformity is a single source
Negotiate for Favorable Contract Terms


Try to negotiate single/preferred currency for all sites—not always possible
Specifically request to be billed monthly via an invoice
•

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

Confirm procurement responsibilities for all necessary devices
•

Provider installation techs typically very specific in their roles (i.e., one tech for Internet
access turn-up and another for VPN installation)
•

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 24x7 to manage/speak with your vendors

1. Negotiating Specific Terms And Conditions
Minimize Multi-Vendor Management Challenges

Request that trouble ticketing and escalation procedures (names & contact info) be clearly
defined within every contract
 Consider contracting with a language line service to deal with communication barriers—
contract on a per usage basis
Negotiate SLAs & Credits


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

2. Local To Global Performance
There is No “Silver Bullet” Global Infrastructure Singly Owned

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
•

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”


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

Peering between many local Asia Pacific ISPs still happens in the U.S.
•


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

3. “Business” Grade Broadband
Seriously Consider Broadband—But Do Your Homework

Providers often have many products differentiated by their contention ratios (oversubscription: 50:1, 10:1, 1:1)—watch what you buy
 If VPN being used you want a static IP—many providers do not offer
 Identify who will provide the DSL router—you may need to procure your own
 Confirm that there is 24x7 support—this is not always true
In-Country Providers Unlikely to Guarantee Performance


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
•
•

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

4. Country-Specific Idiosyncrasies
Become Familiar with Local Infrastructures
Government Firewalls (e.g., China)


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)

In this scenario there are limited outbound connections to only certain government approved
providers—they determine how traffic is routed/handed off
•

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)

Bandwidth cost within country very different than leaving the country—same with
performance
 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

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
Virtela’s proprietary IP Service Fabric (IPSFsm) multi-connects its customers to the best
regional and global infrastructures around the world
 Our power is in the ability to quickly and seamlessly move traffic from one of these
underlying backbones to another

17
Role Of QoS – What Should You Demand?
“Performance” is Important
 We have customers running IP video and VoIP with QoS and others without
 Have customers running VoIP over broadband internationally
Business Drivers are Always Present
 Cost, delivery timeframes, technology availability, etc.
Some Realities…
 We Connect to Backbones Around the World…They’re Overbuilt & Under Utilized (IP, MPLS,
etc.)
 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
 Last Mile is Still the Key
 What About Broadband (DSL & Cable)?

|
+1.720.475.4445
18
So MPLS Is The Way To Go
You’re Tied to One Provider
 No flexibility to choose technology & provider by location
 MPLS CoS does not transfer between carriers
Who is the Best Provider?…What Defines Best?
 Is it price?
 Is it single source…one throat to choke?
 Is it best performing network infrastructure by city, by country?

Summary
Always a Healthy Dose of Reality Incorporating Business
Requirements
 There are business, availability, and interoperability constraints to consider re: MPLS
everywhere
 Then again, DSL is not a T-1
It’s About Performance for Your Environment
 Not MPLS or COS, etc.
 What are the requirements versus assuming…why overbuild & overpay
What’s the Provider’s Role in QoS?
 It’s critical & it’s end-to-end (LAN through WAN…the application)
