Pros

• Highspeeds and bandwidth - Frame Relay packet switch tech.
• Ease of Implementation - Service provider handles data tranport link.
• Scalable - Equipment cost (CPE) is the same independant of bandwidth.
• Multiple connections - Redundancy.
• Technology to choose - no one-size-fits-all solution.
  • Frame Relay, HDLC, PPP
  • ISDN (PRI,BRI), T1, T3, DSL, Dialup

Cons

• Equipment is expensive.
• WAN connection handled by the provider. Provider must correct data transport link problems.
• Routing would be much more complex - determine exactly where each subnet would be advertised.
• More options - connectivity that would need to be considered.
• Expensive - bandwidth at a cost.
