2 01/28/11 ICCCI2010,Madurai,July:22-23,Tamilnadu,Karnataka. 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

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.

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 . IPv6 over Fiber Dual Stacking Internet IPv6 Over Fiber
