Xcentric Cloud Network Connectivity Guidelines

Calculating connectivity requirements can be more of an art than a science. The Internet can be used for so many functions (web browsing, email, radio, video, file transfer, video conferencing, etc.) and each has its own unique and specific requirements. Understanding the approximate profile of how a firm will use the internet will drive the overall requirements for how to properly configure a shared internet connection for connectivity to the Xcentric Cloud Network.

Guidelines for proper Internet connectivity

Bandwidth

As a general guideline, we estimate that each concurrent user will require approximately 80K per connection. This estimate will vary based upon several factors:
  • the number of monitors per user
  • frequency and size of document scans
  • frequency and volume of file transfers to/from the datacenter
  • frequency and volume large print jobs
  • any additional demand from other Internet-based applications (YouTube, Internet Radio, etc.)

Per office  (using a shared Internet connection)
We find that firms with 16-18 users that work in any one office simultaneously and share the Internet connection will require a single T-1 (1.554MBPS) connection or equivalent.  Accordingly, each office will require additional bandwidth to accommodate a larger number of concurrent users.  

Sample configurations
20-user office          Two T-1s or 3-MBPS Business Class DSL
50-user office          Three T-1s or 5-MBPS Business Class DSL


For home users
Good quality DSL or CableModem service will typically exceed the needs for approximately 5 concurrent Xcentric Cloud users.  


For roaming users
Cellular air cards can provide a convenient connection when users are out of their office or at a customer's site.  Although connectivity is available within range of the cell towers, the speed and stability of the connection can vary depending on location and surrounding object interference.


Secondary Connection
Each office should consider the use of an additional circuit as a fail-over connection. Ideally the fail-over circuit will be from a provider that differs from the primary circuit to minimize single point of failure due to any one vendor outage.
