ipv6.pptx (Size: 1.4 MB / Downloads: 23)
WHAT IS INTERNET PROTOCOL?
PRIMARY NETWORK PROTOCOL USED ON THE INTERNET
SUPPORTS UNIQUE ADDRESSING
ROUTES NETWORK PACKETS ACROSS NETWORK BOUNDARIES
SET OF RULES HOW PACKETS ARE TRANSMITTED OVER THE INTERNET
ROUTERS ARE THE FUNDAMENTAL BLOCKS
WHAT IS IPv4?
CURRENT STANDARD PROTOCOL FOR THE INTERNET
IT OPERATES ON BEST EFFORT DELIVERY MODEL
USES 32-BIT ADDRESSES
IPv4-LIMITING FACTORS
Running out of internet addresses
System management costs
Forces users to use Translation(NATs)
Security related issues
Address configuration related issues
Difficult to add support for future needs
IPv6 part of the future
IPv6 Solves many of the problems caused by
the IPv4 success and more...
Will the whole Internet get upgraded any time
soon?
—No way!
—Although some sites considering use of IPv6
IPv6 offer useful features for Today's network
CONCLUSION
IPv6 is ready for deployment
—all the components are now in place
Most mobile systems need IPv6
—the participants are much more committed
to it now than 6 months ago
—Agreed standards are coming
Large-scale trials and experiments
—Needed and happening
