      • Problems with IPv4 : Limited Address Space
      • IPv4 has 32 bit addresses .
      • Flat addressing (only netid + hostid with “fixed” boundaries)
      • Results in inefficient use of address space .
      • Class B addresses are almost over.
      • Addresses will exhaust in the next 5 years .
      • IPv4 is victim of its own success .
    • 2 01/28/11 ICCCI2010,Madurai,July:22-23,Tamilnadu,Karnataka.
      • Problems with IPv4 : Header Limitations
      • Maximum header length is 60 octets.
      • (Restricts options)
      • Maximum packet length is 64K octets.
      • (Do we need more than that ?)
      • ID for fragments is 16 bits. Repeats every 65537th packet.
      • (Will two packets in the network have same ID?)
      • Variable size header.
      • (Slower processing at routers.)
      • No ordering of options.
      • (All routers need to look at all options.)
    • 2 01/28/11 ICCCI2010,Madurai,July:22-23,Tamilnadu,Karnataka. Problems with IPv4:Other Limitations
      • Lack of quality-of-service support .
        • -Only an 8-bit ToS field,which is hardly used.
        • - Problem for multimedia services.
      • No support for security at IP layer .
      • Mobility support is limited .
    • 2 01/28/11 ICCCI2010,Madurai,July:22-23,Tamilnadu,Karnataka.
      • Summary of IPv6 Main Benefits.
      • Larger address space.
      • Expanded routing and addressing capabilities
      • Improved support for extensions and options
      • Flow labeling (for QoS) capability
      • Server-less Auto-configuration(Plug and Play), Reconfiguration and Neighbour discovery(ND)
      • Authentication and privacy capabilities
      • Simple transition from IPv4 .
      • Built in Strong IP-layer Encryption ,Decryption and Authentication.
      • Real time applications like Video & Audio .
      • More efficient and Robust mobility mechanisms .
      • Improved support for options and extensions.
      • Streamed Header format simplification
    • 2 01/28/11 ICCCI2010,Madurai,July:22-23,Tamilnadu,Karnataka. IPv6 Header Format . Traffic Class Flow Label Vers Payload Length Next Header Hop Limit 128 bits Source Address 128 bits Destination Address 0 4 12 16 24 31
      • From 12 to 8 Fields (40 Bytes)
      • Avoid Checksum redundancy .
      • Fragmentation end to end .
      • 40 Bytes
      • Addressed increased from 32 to 128 bits .
      • Fragmentation and Options field removed from Base Header.
      • Header Checksum removed.
      • Header length is only Payload.[Because Fixed Length Header].
      • New Flow label Field.
      • Tos->Traffic Class.
      • Protocol->Next Header.(Extension Header).
      • Time to Live-> Hop limit.
      • Alignment changed to 64 bits .

      • IPv6 over Fibre Impact on Hardware
      2 01/28/11 ICCCI2010,Madurai,July:22-23,Tamilnadu,Karnataka. Only drivers have to be rewritten for the NIC. No changes required for manufacturing it . Routing Table will consist of IPv6 Address and smaller routing table entry. No MAC address to IP mapping is required resulting in router performing faster and more Efficient. Layer 2 switches will be obsolete or will have to run dual stack. Layer 3 switches will experience faster packet processing .
    • 2 01/28/11 ICCCI2010,Madurai,July:22-23,Tamilnadu,Karnataka.
      • Once the new architecture is in place, a dual stack is needed to process packets transmitted from both the current architecture as well as the new architecture .
      • The protocol initiated will automatically choose the appropriate stack .
      • This will be an international standard to be used by all Internet applications especially for real time applications .
