What is the enemy of IPv6 and VoIP?

No matter whether enterprise users are ready or not, IPv6 network deployment is just around the corner. The demand for advanced site selection technology is growing, and everything in life will be able to use this technology.

At the same time, VoIP has become the mainstream technology and has become the basis of other network services. It is no longer the concept of "Next Generation" voice networks. So our worries also follow: What impact will these two inevitable technologies bring to our lives when they encounter each other?

A few years ago, due to bandwidth restrictions, we were very worried about the future of VoIP. Due to real-time requirements, voice data tends to use very small data packets. In fact, to implement VoIP with Low Bit Rate encoding and decoding technology, a typical data packet size is only 20 to 40 bytes. Because small data packets can effectively avoid latency. The above concerns are also caused by the increase in the bandwidth of voice data during the VoIP transmission process, which requires at least 20 bits of IPv4 data packets plus at least 8 bits of UDP data. Now that the IPv6 era is approaching, the size of the packet header will be at least doubled.

As we expected, IPv6 networks will come to us sooner or later. I have been thinking about the impact this will bring to us, especially the VoIP that everyone is always concerned about. After all, VoIP has become a major driving force for voice technology in the past decade. At least in the IPv4 era, we accept this fact. IPv6 is a double-edged sword for VoIP. In the positive aspect, IPv6 will add additional control functions such as priority, which makes VoIP more perfect. In addition, the increase in IP address space is also its biggest benefit.

At the same time, voice packets tend to be smaller packets, and usually require 64-bit bandwidth. Therefore, we can add a UDP header and an IPv4 header to it, which is an extra burden. Deployment of IPv6 networks will undoubtedly increase this burden.

At present, IPv6 will at least double the size of the VoIP packet header. Will this cause a disaster to VoIP? You are welcome to give your comments!
