Concentric Network Corporation White Paper, Outsourcing Remote Access Services

10/1/1998 4

Technical Outsourcing Issues

Probably the single biggest obstacle to outsourcing remote access has historically been a lack of

adequate tunneling technology and security measures. The recent development of standards for

tunneling technology, such as Mobile IP, as well as authentication protocols such as RADIUS, now

allows for management of the security function by the end user organization.

This same technology permits the use of user authentication tokens to produce one-time passwords,

and allows for a very high level of security and user authentication. The Network Service Provider

now need not be the keeper of the user ID and password database, as the security server can reside

at the end user customer site.

An additional technical issue which impacts the ability to outsource a remote access network, is the

“transparency” of the solution. End users need for their remote access solution, whether an in-house

service, or an outsourced one, to provide multiprotocol support for IP and IPX clients, and IP

addressing via dynamic assignment (using the end user customer’s address space, not the NSP’s IP

addresses). In addition, the solution should not impose restrictions on the client software supported, or

on the customer premises routing equipment to be used. Until recently this was not possible with an

outsourced offering. With RemoteLink™ (which is based on the mobile IP and Generic Routing

Encapsulation IETF draft standards and RFC’s), it is now possible to outsource your remote access,

and provide an elegant solution which addresses these issues.

Service Overview

The Concentric RemoteLink™ service is a Virtual Private Network (“VPN”) application that gives

large number of remote end users and needs to give remote access to centrally located

corporate information access points. The technology infrastructure supporting Concentric

RemoteLink™ is based on Bay Networks remote access servers, routers and dial virtual private

network services software, however the customer premises equipment router may be from other

vendors.
