Why SDCOE wanted VPN

• Two networks: mainframe and IP network

  • Staffing for 2 networks
  • $220,000 per year mainframe network costs

• Front end processors (FEP’s)

  • No capacity left on FEP’s
  • FEP limited to 19.2 performance

• Use TCP/IP rather than Poll/Select protocol

• Security of data from desktop to server
