Key Considerations for Deploying an Ethernet-based Converged Services Wide Area NetworkJeff Smith, Head of Product and Marketing, EMEA20 October 2010

Challenges Facing our Business Customers

2© 2010 – Global Crossing

Meet enterprise applications’ demands

• Converged services• Large and flexible bandwidth

requirements• Data and traffic profiles• Storage, backup and recovery• Performance , Service Reliability

and Quality of Service

Support enterprise business dynamics

• Geographic, global reach• Expansion or contraction of

facilities• Interconnection of data centers,

headquarters, remote locations• Security

Global economic conditions are increasing demand for Ethernet and IP MPLS VPN services as companies seek to do more with less.

Ethernet WAN Drivers

3

Uses familiar LAN technology• Leverages current skills and knowledge of IT staff

with Ethernet experience• All sites on an Ethernet WAN appear to be on the

same network – regardless of their actual locations

Delivers global access for high bandwidth and high utilization needs; ideal for data center connectivity.

Increase efficiencies over legacy network infrastructure

Provides Privacy and security, while giving the customer full routing control

Economies of scale to support converged services on a single connection

Rapid and flexible service provisioning Interworking between Layer 2 (VPLS) and

Layer 3 (MPLS) Ability to priority-rank traffic to maximize

bandwidth utilization and protect data

Regions/countries to be connected? Number of locations? Architecture – Point to Point, Hub and

Spoke, Any to Any? Bandwidth requirements by site? Access service availability and options? Legacy protocols support? Back-up or diversity requirements? Current edge equipment and interface

capabilities? Converged IP services? Technical staff and skill sets? Traffic sensitive applications and QoS

requirements?

How do you choose?

EtherSphere or Layer 3 VPN – Best Fit Considerations

EtherSphere (MP2MP) "Best Fit"

Customer wants control of routing protocols

Leverage existing Ethernet interfaces Smaller, less complex network Customer requires large data center

connectivity Support for non-IP protocols Support for IP multicast Can connect Layer 2 switches Customer manages their own equipment Ideal for large bandwidth sites requiring

flexibility and customer control

5

Layer 3 VPN “Best Fit”

Customer wants to outsource IP routing

Customer handoff requires non-Ethernet, e.g., FR, PPP, HDLC

Ethernet connectivity is not needed Large number of sites need to inter-

network Need to connect hard to reach off-

net locations Managed Services preferred Allows for access to RVA, VOIP, and

video gateways

Let’s Consider a Case StudyBackground

Company OverviewMultinational enterprise with headquarters and data center in the UK.

Original customer network architectureIPSEC tunnels over public Internet. Currently each office purchases their own Internet connection.

Customer's goals and decision criteriaImprove network and application performance, simplification, lower total cost of ownership, ease of management.

Let’s Consider a Case StudyResults

Why this was a good fit for the customerEthernet WAN services provide a global solution from a single service provider. Layer 3 offers access to smaller remote locations. DIA provides further extended reach to rest of world.

Benefits for the customerCompany was able to replace multiple circuits from multiple providers and deploy a single converged private network. It allows them to partner with one global provider and improve end user experience.

Key learningsEthernet WAN is not the end game. It is part of the overall solution for customers to apply for multi-site networks.

How to Choose?

Requirements gathering • Technology evaluation • Provider evaluation

Define upcoming business needs including organizational and structural changes that could affect WAN capacity planning

Review network performance statistics, usage details and plans for new applications

Discuss technical details like multicast routing protocols, diversity, load balancing, and network security

Define selection criteria and how these will be applied – to the solution and the vendor
