IPv6 is the foundation on which the next generation internet will be built. The new software’s and hardware’s built on IPv6 platforms have to interoperate with IPv4 network.
IPv4 has proven to be a great technology, but its limited IP address space is unable to meet the huge increase in demand forIPv4 addresses. Translation techniques like NAT extended IPv4 life. IPv6 not only solves the shortage of IP address but removes shortcomings of NAT. end-to-end security, performance bottlenecks and peer to peer networking.
Other characteristics of IPv6 include flexibility, improved routing of data, improved QoS and enhanced mobility features for wireless. Further IPv6 integrates Internet Protocol security to improve authentication and confidentiality.
How IPv6 affects you?
Impact - IPv6 is a replacement to the widely used Internet Protocol version 4 (IPv4). Most of the hardware and software in use already support both IPv4 & IPv6. It has to be enabled, configured and tested to meet your requirements, before using it on the production network. Some legacy applications and hardware support only on IPv4 and hence some components may have to update and/or replaced.
Opportunity-IPv6 allows devices to have its own unique IP address. This allows better voice and video application. Better mobility applications. It lowers network administration load. IPv6 has strong authentication and encryption.
Risks – IPv6 transition should be carefully planned and tested. Improper design and inadequate testing methods can lead to service disruptions and devices will be more vulnerable to external threats.
Different techniques or strategies are used in deploying IPv6. It is also possible to run IPv4 and IPv6 throughout the network, from all edges through the core, or to translate between IPv4 and IPv6 to allow hosts communicating in one protocol to communicate transparently with hosts running the other protocol. All techniques allow networks to be upgraded and IPv6 deployed incrementally with little to no disruption of IPv4 services.
Deploying over a Tunnel
These tunnels encapsulate the IPv6 traffic within the IPv4packets, and are primarily for communication between isolated IPv6 sites or connection to remoteIPv6 networks over an IPv4 backbone. The techniques include using manually configured tunnels, generic routing encapsulation (GRE) tunnels, semiautomatic tunnel mechanisms such as tunnel broker services, and fully automatic tunnel mechanisms such as IPv4-compatible and 6to4.
Deploying dual stack
This technique allows IPv4 and IPv6 applications to coexist in a dual IP layer routing backbone. All routers in the network need to be upgraded to be dual-stack with IPv4 communication using the IPv4 protocol stack &IPv6 communication using the IPv6 stack.
Deploying IPv6 over MPLS backbone
This technique allows isolated IPv6 domains to communicate with each other, but over an MPLS IPv4 backbone. Multiple techniques are available at different points in the network, but each requires little change to the backbone infrastructure or reconfiguration of the core routers because forwarding is based on labels rather than the IP header itself.
Deploying IPv6 over data links
This technique enables isolated IPv6 domains to communicate by using the same Layer 2 infrastructure as for IPv4, but with IPv6 using separate Frame Relay or ATM PVCs, separate optical links, or dense Wave Division Multiplexing (dWDM).
