Multi-site small/medium
business (SMB) WANs:
responding to the challenges and
opportunities of last mile access
Outline
• A bit of background on ePipe
• The rise of broadband
• Defining the needs of distributed business
leveraging broadband access solutions
• Reality hits: last mile challenges
• A timely solution: Layer 3 bonding (ML-IP)
• Illustration of ML-IP operation
• ML-IP deployment enhancing broadband
• Service provider, ISP and ASP deployments
• Conclusion
The Broadband Revolution
is Coming!
• Broadband adoption for low cost, high
bandwidth is booming
• Internet usage continues to grow
• Businesses becoming Internet-dependent
• VPN accepted and deployed as a costeffective alternative to costly frame relay
• Last mile access can either hinder or help
depending on what is available!
The revolution has begun…
Hot applications:
• File sharing
• Image transfer
• Financial services
• Collaborative
development
• Extranets with
suppliers
• Advanced retail
transactions and
training
The Impact of Broadband
Broadband
• 56% of businesses view their
BB service as indispensable
• Business class options w/
SLAs growing daily
• 300 million residential and
commercial locations by 2007
• Growth rates predicted of 3070% per year depending on
location and broadband type
Broadband enables:
•
•
•
•
•
•
Cost-effective VPNs
Productive telecommuting
Business Internet use
Distance learning
Advanced retail apps
Extranets with suppliers
and customers
• Much more….
Broadband enables incredible application
connectivity at a very accessible price!
What does this mean for SMBs?
• > 6 million SMBs in North America
• > 65% SMBs are connecting multiple offices
• VPN use by these SMBs will double in 2002
Easy to implement, affordable VPNs, Internet access and other
applications + affordable broadband = revolutionary networking!
SMBs are the backbone of the economy. Broadband brings
effective, affordable data access to this critical market segment!
Are all needs being met though?
What multi-site SMBs really want from their last-mile
solution to be truly effective:
• Bandwidth flexibility: buy only what they need
from who they want, at the start and as they grow
• Cost-effectiveness: price must be reasonable and
commensurate with business enabled
• High availability: can’t afford downtime and loss
of $, and refuse to pay for unused redundant links
• Ubiquity across locations: must be universally
deployable
Sound like reasonable requests, but the industry
isn’t quite there yet….
Today’s reality…
How does reality of today match up to
the last mile needs of SMBs?
• Bandwidth flexibility: buy only
what they need from who they want,
at the start and as they grow
• Cost-effectiveness: price must
be reasonable and commensurate
with business enabled
• High availability: can’t afford
downtime and loss of $, and refuse
to pay for unused redundant links
• Ubiquity across locations: must
be universally deployable
Location can’t get broadband,
so they are stuck with
inflexible slow dial modem
They want the power of
frame at HQ, but can’t afford
FR cost at branches
They love broadband but
it’s not reliable
Unavailability of some
solutions at locations means
non-ubiquitous solution
Enter ePipe’s ML-IP
Multilink IP (ML-IP) boosts the bandwidth and
uptime of a VPN, WAN or Internet Access solution
by utilizing transparent link aggregation with fail
over that is independent of access technology or
network provider, allowing customers to scale
their bandwidth at any location, on demand.

ML-IP provides true aggregation bonding – not
performance-limited load balancing or sharing!
How Does ML-IP Address Key
Customer Requirements?
ML-IP Solution
BANDWIDTH
ML-IP allows bonding of multiple DSL, cable, dial,
ISDN, FR, ATM and/or LL to scale incrementally to fit
exact bandwidth needs
COST
ML-IP’s flexibility allows customer to use the most
cost-effective services to meet their needs
HIGH AVAILABILITY
Through powerful link resiliency management, ML-IP’s
failover and dial-around capabilities insure the
customer network stays up
UBIQUITY
ML-IP works at the IP layer and is transport and access
link agnostic, so you can use the service / provider of
choice at each site – even multiple providers

• Reliability to insure customer access to applications
• Lower latency for better application performance
Unique Advantages of ML-IP
Layer 3 Bonding for VPNs
• Link type agnostic
• Use the transport provider of your choice – even
use multiple transport providers
• No need to involve service provider to deploy
• Compatible with any IP-based application
• Fragmentation = low latency + added security
• Support of asymmetrical (many to any) links
match real-world implementations
ML-IP bridges the gap!
Conclusion
• Broadband access is a revolutionizing technology that could
redefine how business is done
• Today broadband solutions have significant last-mile issues in
search of a good solution.
• Businesses keep evolving faster than networks can manage, so
solutions need to be customer-centric, not network-centric
• Technologies like ML-IP are the future: enabling reliable
bandwidth without tying customers to specific access or
transport networks
