What is an Extranet?

• An extranet is a private network that uses the
  internet protocols and the public
  telecommunication system to securely share part
  of a business's information or operations with
  suppliers, vendors, partners, customers, or other
  businesses. An extranet can be viewed as part of
  a company's intranet that is extended to users
  outside the company. It has also been described
  as a "state of mind" in which the internet is
  perceived as a way to do business with other
  companies as well as to sell products to
  customers. www.whatis.com

Applications

• Electronic data interchange (EDI)
• - Original extranet applications
• - Exchange business transactions between
• peer businesses.
• - Lack of product selection and a universal
  
• communications protocol.
• Order entry systems
• - Intel Corp., General Motors Corp.
• - Automotive Network Exchange(ANX)
• - Value Industry Parts Heavy Duty(VIPAR)
• Remote Development

5
Connecting

• Asynchronous Transfer Mode T-3 speeds and above
  or 45Mbps and up.
• Frame Relay up to T-3 speeds.
• Local telephone company or long distance carrier
  provides line.
• Faster the connection, the more it will cost.
• Web based extranets often require a Web server,
  usually a database system, and possibly an
  application server.
• New developments in Virtual Private Networks

6
Standards

• Extensible Markup Language (XML)
• - Markup methodology for explicitly
• marking data fields in text files.
• - XML allows for a common document
• type for all networked parties.
• Commerce XML (cXML) by Ariba Corp.
• - Defines a set of document type
• definitions (DTDs) for XML documents.
• Open Buying on the Internet standard (OBI).
• - Uses digital certificates and signatures.
• - Ultimate goal to establish The Trading
  Web

7
Standards

• Common Object Request Broker Architecture
  (CORBA). It uses Internet Inter-ORB Protocol
  (IIOP) and TCP to request and reply.
• - Alliance between Netscape, Oracle, and Sun
  Microsystems to ensure standards of extranet
  products.
• Microsoft has DCOM and its own distributed object
  architecture which uses Point-to-Point Tunneling
  Protocol (PPTP)

8
Security

• An extranet requires security and privacy. These
  require firewall server management, the issuance
  and use of digital certificates, digital
  signatures or similar means of user
  authentication, encryption of messages, and the
  use of virtual private networks (VPNs) that
  tunnel through the public network.

  partners.
• Improved processes reduces costs
• Faster time to market
• Increased partner and customer loyalty
• Just-In-Time (JIT) inventory systems

Conclusion

• With key developments in open systems standards,
  such as XML, higher levels of security with
  digital certificates and encryption, and VPNs
  allowing secure data exchange, extranets are
  changing the way companies compete.
