IPv4 addresses are 32 bits which limits the addresses space to 2^32 addresses. With the growing demand of internet connected devices there is a need of bigger address space. IPv6 provides 128 bit addressing mechanism. As IPv4 address space is exhausting, IPv6 migration becomes imminent. IPv4 to IPv6 migration is not an easy task considering the complexity of the internet. This solution to transition IPv4 to IPv6 is yet to be discovered and the immediate solution is interoperability between existing IPv4 and upcoming IPv6 networks.

Client Requirements
IPv4 addresses are 32 bits which limits the addresses space to 2^32 addresses. With the growing demand of internet connected devices
there is a need of bigger address space. IPv6 provides 128 bit addressing mechanism. As IPv4 address space is exhausting, IPv6
migration becomes imminent. IPv4 to IPv6 migration is not an easy task considering the complexity of the internet. This solution to
transition IPv4 to IPv6 is yet to be discovered and the immediate solution is interoperability between existing IPv4 and upcoming IPv6
networks. The problems which have been encountered:
Absence of seamless and transparent connectivity between incompatible and disjoint IPv4 aware applications across external
IPv6 network.
Legacy applications unable to communicate on newer IPv6 Network.
Often there are DoS (denial of service) attacks on IPv6 routers, and even legitimate traffic generates excessive load on endpoint
routers.
Incompatibility with l2tp implementations with various independent software vendors.
Incompatibility with PPP with some telecom equipment.
Xavient Solution
We aimed to achieve seamless end to end connectivity between customer premise equipment ( router) to ISP routers and achieved
measurable improvement in reduction to Average Ping Latency Time through better implementation of transport algorithms.
The solution was provided while giving consideration to the following scenarios:
Customer (IPv4 ) to ISP's IPv4 network though a IPv6 intermediate network using IPv4 over IPv6 tunneling.
Customer (IPv6) to ISP IPv6 network using tunneling over IPv4 intermediate network.

Benefits
Transparent and seamless communication between newer IPv6 and Legacy applications
Increased rating on the American Consumer Satisfaction Index
Increased satisfaction from end users
Legacy applications need not be rewritten and they continue to function normally without any changes
No need of investment on newer routers and only firmware was modified
Reduction in round-trip packet transport latency within tunnel by optimizing code
Easy web interface based management of device to make configuration changes
