Basic Components of Internetworking
Infrastructures

• Network-refers to the technologies (hardware and
  software) that permit exchange of information
  between processing units and organizations
• Processing Systems-encompass the hardware and
  software that together provide an organizations
  ability to handle business transactions
• Facilities-the physical systems that house and
  protect computing and network devices (no bling)

11
Elements of Networks

• LANS
• WANS
• ROUTERS
• FIREWALLS AND OTHER SECURITY SYSTEMS AND DEVICES
• CACHING, CONTENT ACCELERATION, OTHER SPECIALIZED
  NETWORK DEVICES

• Mainframe Devices and Systems
• Middleware
• Infrastructure Management Systems
• Business Applications

• Outdated
• Obsolete
• Proprietary technologies
• Nontechnical Challenges
• Processes
• Organizations
• Cultures

Future of InternetworkingInfrastructure

• Not all expectations can be met universally
• Physical infrastructure of areas should be a
  concern
• Developing countries with limited resources are
  hesitant to invest or incapable of making large
  investments in assuring consistent and sound
  physical infrastructures that support
  internetworking infrastructures
• Aging infrastructures in the developed world are
  not maintained and/or updated to new standards
• How to cope with different degrees of internet
  access?
• What if customer has lower bandwidth than needed
  for live Web conferencing?
• Security still evolving
• Authenticity and contracts are an issue
• Confidentiality problematic due to lack of
  complete interoperability of various platforms
