RITA+VPN: INTERNET
COMMUNICATIONS
Internet is predominately a communications tool.
TCP/IP: Transmission Control Protocol/Internet Protocol
 Developed in ’73 by Vint Cerf.
 Used widely by D.O.D. in the 80’s.
 Defacto networking standard for UNIX systems.
Finally implemented by Microsoft in Windows’95.
Became Microsoft standard networking protocol with
“Windows98”.
Packetizes data, transmits through a series of routes.
Many to many topology, redundant.
The Old Way:
LEASED DATA LINES
Traditional approach to data communications to
distributors branches.
Very reliable, low in bandwidth, expensive.




9600 baud (9.6Kbaud) analog, point-to-point, 2 or 4-wire
leased lines.
56,000 baud (56Kbaud) digital circuits.
Frame Relay -- geographically diverse areas.
(proprietary version of the Internet developed by telcos)
Simple dial-up phone lines (non-toll)
Costs range: $50/mo for simple dial-up, to nearly
$1000/mo for higher speed data circuits



Expensive when crossing telco borders.
Held high due to local telco tariffs and fees.
Usually “leased” by the customer.
Dumb Terminals vs.
IP-based Devices
Dumb terminals/printers “serial communications”:




Requires one-to-one connection between host and terminal.
Multiplexors enable multiple serial devices over single
circuit.
Moderately expensive communications gear (modems,
DSU's, multiplexors).
Terminal equipment; affordable, simple, easily maintained.
“IP” based devices:




Communications traffic carried over common link.
Inexpensive communications gear (routers, hubs).
Terminal equipment (PC’s/Print Servers); expensive,
complex, software maintenance.
Personal productivity software; word processing,
spreadsheets, internet access, email and multimedia.
RITA - Remote Internet
Terminal Access (telnet)
Communications is carried over Local Area Network
(LAN) or Internet




Uses low-cost, local connection to Internet.
No long distance toll charges or expensive leased line.
Ideal for a telecommuter or mobile sales force.
Can provide “Extranet” access B2B – UASI/Westgate
RITA - Remote Internet
Terminal Access
TELNET: Widely used method of communicating
between computers.




End-users computer is simple display device.
Terminal Emulator/TELNET program used to connect to
host/server.
Host computer processes all keystrokes, controls access to
software & data.
Very prevalent in today's mainframe/legacy systems.
RITA - Remote Internet
Terminal Access
Security issues;






Communications is un-encrypted.
Can be eavesdropped on (theoretically) by unscrupulous
individuals on the Internet.
Hardware based firewalls must be deployed.
Login/passwording must be well managed on servers.
All Window’s PC’s have some form of “telnet” built-in.
Software change so only “root” can change passwords.
VPN – Virtual Private
Network
Encrypted communications between devices.


Both ends use a common encryption key, also known as a
"private key".
VPN router devices uses private key to encrypt all packets.
Secure/reliable, even on public networks.
VPN TUNNELING Wide Area Network
Encrypted “tunnel” through the Internet.
Local Area Networks (LANs) connected as a Wide
Area Network (WAN)
Enables secure exchange of all types of networked
based services:



RITA - Terminal Emulator/TELNET program used to connect
to host/server.
File and Print Sharing, Network File System(NFS), I: drive.
All services typically associated with a Local Area Network
(LAN)
Security Issues Dramatically Reduced
Other Internet Services
Internet access means much more than just
communication route.


Web Browsing: Enable PC users to visit manufacturers web
sites for product information and the ability to place and
check on the status of orders.
Email: Perhaps the most ubiquitous tool for the 20th century.



Instant Messaging:



Replaces phone calls to branches (and long distance tolls).
Send email to multiple parties at the same time, reduces
duplicate efforts.
Newest, instant, non-verbal, communications.
Rivals telephone in ability to interrupt.
VoIP: Voice-Over-Internet-Protocol.

VoIP phones allows connect telephone handsets in the branch
to the main phone system in your central office.
Types Of Connections
"IP" communications utilize a variety of types of
Internet connections.



T-1 circuits provide the highest bandwidth available;
1500Kbaud. Highest price point too; $900-$1,500/month.
DSL (Digital Subscriber Line)/Cable modems offer fast
speeds; 128Kbaud-768Kbaud. Less expensive; $30$120/month.
Simple 56Kbaud dial-up circuits; $15-$25/month plus cost of
phone line. 56Kbaud dial-up lines should be used only as a last resort for
small branches.
Full-time access needed at main office.
“Static IP address” required.
CASE STUDY
Moderate sized, independent welding
supply/industrial gas distributor in
Southeast.
 Four remote branches, 150mile radius, 2
crossed state lines (inter-lata).
 Traditional 4-wire, 9600 baud, analog,
leased lines = $1,200/mo for 3 branches.
 Estimated cost of 4th branch prohibitive at
$800/mo. Total = $2,000/mo.

CASE STUDY







56K point-to-point digital circuits rejected. No
savings.
56K Frame Relay rejected. Small savings, large
hardware investment.
DSL implemented at main office ($80/mo) and 2
branches ($60/mo) = $200/mo.
Cable modem at 2 branches = $75/mo.
Total Internet Connectivity = $350/mo.
Estimated savings = $1,650/mo.
15 month Return On Investment
PITFALLS

DSL & CableTV ramp-up problems.







Installation schedules typically aren’t met.
DO NOT OPT FOR SELF-INSTALLATION.
DO NOT DISCONNECT LEGACY EQUIPMENT (leased
lines) UNTIL NEW SERVICE IS FULLY FUNCTIONAL.
Do not sign long-term contracts.
PC’s require more software maintenance &
configuration.
Employee training considerations.
Internet acceptable use policy needed.
