Report Card

Network Computing is a technology magazine covering the enterprise and service provider network market. We focuses on product testing and workshops in the form of comparative reviews, Sneak Previews and technology workshops. Our editorial staff comprises highly technical and nontechnical users. Our staff resides in several states, and the bulk of our work is performed online via e-mail, file transfers and Web applications. Some of our technology editors also use Microsoft Windows and X Window applications remotely.

Network Computing is moving to enable its mobile-technology editors to have secure, reliable access from remote locations. The Network Computing labs are distributed across the country, and we have several contributing editors on external networks. In addition, our editors often work from home or from other remote locations when traveling on business. We use a series of ad hoc methods for remote access, mostly through unsecured dial-up networks. Full-time Network Computing personnel use local access providers when not in the office, and when traveling they use corporate accounts with AT&T dial-up. Network Computing has a fledgling Web-based intranet that all editors access on a regular basis, as well as e-mail. The e-mail system is both Web-based over SSL as well as POP3 and IMAP over SSL. All other applications travel over the Internet in the clear, and that is unacceptable.

The Mission

Our goal is to provide seamless access for our editorial staffers to Network Computing applications regardless of their connectivity or origin. Many applications are Web-based. However, some are Windows 32-bit apps. All network applications are IP-based. Network Computing has a fairly fluid environment and we need support for existing applications, as well as temporary access for applications used in testing. We are consolidating our user management to a directory structure, however, that is an ongoing project. We have user databases on Windows NT 4.0, NDS and Unix passwords. Any of these user databases may be used to authenticate users. Each lab manages its own authentication server, and there are no trust relationships established.

We don't want to support software running on end-user computers, so a support line needs to be available for users regardless of where they are calling from. For the most part, our users are in the continental United States. We occasionally travel out of the country, so international support is a plus but not a requirement.

Technical issues to be solved:

• Many of our users reside behind NAT'd networks or have to get pass-through firewalls when traveling. We can't dictate firewall changes; the solution considered must be able to work around this (or please document your limitations).

• We have users running various versions of Windows, Linux and MacOS, all of which must be supported.

• We can't recompile binary applications to add dynamically linked libraries that support secure transport.

• Only the applications we wish to support must be secured end-to-end. All other Internet access can travel from the local desktop to the Internet.

• If CPE equipment is required, we will need to know in advance the product-infrastructure requirements.

• Many of our labs maintain separate user-authentication databases. Leveraging the existing databases would be ideal, however, we will consider alternatives such as hosting the remote user credentials externally.

To aid us in evaluating this RFP, we will need the following information:

• A detailed description of the NOC, specifically regarding redundant systems and failover policies. Statements of opinion from third-party auditors would be helpful in this regard.

• Written assurance that the service is managed in a secure and responsible manner and in keeping with industry best practices.

• A description of support levels available, including escalation procedures and the associated costs.

• Service-level agreements pertaining to service availability and support times. In addition, we need a description of remediation in the event of SLA violation.

• A listing of the certifications technicians have or are actively working towards and a percentage of the workforce with certifications.

• Pricing broken out by fixed and variable costs on a periodic basis. Please provide pricing denoting initial installation price and on-going costs for a user base of 1,000.

• Pricing should include the costs for service modifications, user additions and deletions, and other ancillary costs.


We will be testing each service without applications for one week per service so we can evaluate the impact of the service. We will make our technicians available to support the installation of the service and get end users up to speed. Since the bulk of our users are remote, we will not be able to bring them together for a joint training session. Initial user configuration must support our distributed model.
