Summary

Foundation concept: Network.

Definition: A communication network provided by a third-party vendor that also provides guarantees of service quality, security, and reliable data transmission.

VANs provide a variety of services together with the connection, including support of a variety of EDI standards (such as ANSI X.12, EDIFACT, and XML), data security standards (for data encryption, a Secure sockets layer, etc.), multiple levels of password authorization, and communication protocols such as X.25 and TCP/IP.

Business value proposition

VANs provide secure networks capable of high-bandwidth data transmission that range from T1 at 1.544 Mbps to OC48 at 2.4 Gbps, together with service-quality guarantees and data security services. The decision to purchase may be based upon the technical need together with the financial aspects of the lease: subscribers pay a base fee plus per-service costs. The analysis of total cost of ownership has to be based upon the use of and need for the services. VANs offer a variety of services and charges are based upon their usage: the amount of data transmitted, fees for connections to other VANs, mailbox charges, help-desk service charges, data-archiving fees, service plan fees, and user and technical training fees.

Summary of positive issues

VANs provide a secure, high-quality, professionally managed and maintained mechanism for connecting with other organizations and entities.
