Because of the various differences in performance and operation, some carriers have better in-region reach than...
their competition. To determine how a carrier can best serve your needs, here are some areas you need to consider:
ISP Internet breakout connections from private global MPLS networks -- Internet breakout for global ISP organizations using MPLS VPNs will normally be achieved by using regional data center footprint and traffic breakouts. Users are grouped by region and connect to the Internet at an access point determined by their location. However, IP addressing allocations may be provided by the ISP from an in-country range. This means, for example, a user breaking out of Europe or the United Kingdom may be sent to Germany for Internet access (again, just an example). Content is restricted, based on the IP traffic source, resulting in a scenario where a user breaking out of the MPLS VPN network from the United Kingdom will not be able to view certain content. Not every organization considers content to be an issue. Any Internet breakout will, of course, require intrusion protection, content filtering and additional security protections. A global security provider can offer a standardized platform, but in-region security may need to be stricter in selected countries -- depending on the type of application and data storage required.
Connectivity types and options -- As a rule, businesses are generally aware of which connectivity types and bandwidth are available when connecting into a single country's backbone. Within developed regions and countries, bandwidth technologies and types, such as flexible fractional 1 Gbps and 100 Mbps Ethernet leased line services, are widely available -- as is digital subscriber line (DSL) technology, fiber or copper. When considering global ISP connectivity, in-region bandwidth (Ethernet or otherwise) will vary, as will the types of lower-cost connectivity such as broadband or DSL. The circuit type must also be considered for extranet customers -- for example, your organization may deal with a supplier to deliver products or services. If it's necessary to connect an extranet partner back into the business, you also need to know the locations of that partner's operations. You should also factor in the cost differences between regions, which can also vary quite widely.
International sites and migration -- The level of involvement from global MPLS network providers depends on whether your organization requires a managed or unmanaged capability. Regardless, the migration to international WAN connectivity requires significant focus and experienced sector resources. Dealing with different time zones, different languages, multiple export and traffic regulations, and other issues requires significant project management expertise.
