VPN SpecificationAn important issue for a VPN request is the varying understanding of the term 'VPN'. Part of the procurement process is a detailed analysis of requirements. By using thorough specification atrexx provides an objective selection process.
All site-specific information is collected in part 1 (site listing) of the request form. Please note that some minimum information is necessary to identify the localization properly. Indications like 'Cairns, Australia' or 'Birmingham, U.K.' are too unspecific, even for a feasibility study. Complete addresses and area codes of telephone numbers are basically needed for any type of quotation.The access characteristic comprises the required bandwidths (speed) and communication protocols. Additional service quality parameters should be specified per site rather than in a general manner.
Part 2 of the request form asks for general requirements:.
The network topology distinguishes between Star and Tree Networks, Meshed Networks (any-to-any), and Point-to-Point connections. atrexx further classifies VPN into Layer-2 VPN and Layer-3 VPN, together with the distinction whether a VPN is established as a single network, from a single provider, or through the public Internet and multiple providers.
Performance and security parameters are strongly influenced by those options. Note, that connections trough the public Internet often traverse several regional IP networks and have to overcome several routing hops on their way. Hence, the Peering Agreements between Internet Service Providers (ISP) are an essential quality parameter for the end-user. Layer-2 networks from a single provider avoid network 'patches' from other carriers and guarantee much better genuine performance. Of course, Layer-3 VPN are also offered by network operators who run their own IP-backbone. The end-user can benefit from such a powerful network likewise.
Scope of Service
The scope of service defines how comprehensive the outsourced service shall be in order to meet the varying buyer requests. atrexx uses the following standard levels of service
Of course, additional specifications can be added to this standard service levels.
Please note: The procurement process and the implementation phase will be more successful the better the analysis has been at the beginning.
VPN via Fiber Networks and via Satellite
Internet via Satellite is a highly performing and cost effective solution to link out-of-reach locations into a global VPN. Hybrid solutions can incorporate almost every place on earth into an Intranet.
