IPv4 is already over 40 years old. It is now facing either early retirement (or perhaps a mid-life crisis) with the upstart of the comparable teenager - IPv6. Fixed and mobile telecoms networks have provided IP services to their customers for some time, initially with broadband data, Voice over IP (VoIP) and now multimedia services, such as IPTV. When a network exceeds 20 million smart phone subscriptions, Carrier Grade NAT (CGN), devised to conserve public IP address space by allocating reusable ‘private addresses’ within local networks, becomes overstrained. The number of smart devices has rocketed over recent years with the success of products from Apple, Samsung and Motorola to name but a few, and it is in the mobile world that IPv4 has truly diminished. With the advent of the ‘Internet of Things (IoT)’, everything from your central heating system to your coffee maker is to ‘go IP’. Home Automation as just one example, will lead to an explosion in the number of devices requiring public IP addresses …particularly if controlled remotely. Fixed networks are too in desperate need of additional address space, assisted by the Internet Assigned Networks Authority’s (IANA) aggressive IPv4 address recovery programme …if only temporarily. In this session, we will be discussing whether IPv6 is truly required to support the rapid growth in IP-enabled devices and if so, is it mature enough to take over and what will happen to IPv4? This talk will also include an overview of some of the issues with IPv4, the benefits of IPv6 to network operators and the impact a change would have on future technologies, such as Software Defined Networks (SDN) and Network Function Virtualisation (NFV).
Who would benefit
This course is suitable for those looking to understand the role of IPv6 in modern telecoms networks.
No specific prerequisites are needed although an understating of IPv4 and its related protocol ecosystem (TCP; UDP; etc.) would be of benefit.
Topic areas include
- Is IPv6 necessary for fixed or mobile networks?
- Will telecoms need IPv6 to support the Internet of Things (IoT)?
- If IPv6 is the way forward, is it mature enough?
- What will happen to all that IPv4 stuff?
- What other technologies will IPv6 impact on, such as SDN or NFV?
