Current Focus, an update

So much happening since my last blog entry.  I’m currently working on two topics at the moment,

  • IPv6 transition architecture
  • SDN/NFV architecture

These are interesting topics respectively.

With IPv6 it seems the more one progresses with this protocol the clearer it becomes that the challenges which exist are not with IPv6 natively 1 so much as the concern with enabling IPv6 and IPv4 to co-exist, with an emphasis on intercommunications between them.  Seems a bit silly I guess, but from what I’ve observed and seen so far, this is the challenge (IPv4 <-> IPv6).  It’s not impossible, however it does require careful consideration; there are many approaches that attempt to solve for the co-existance between IP protocols, each with their own strengths and weaknesses.  So the good news is there are solutions ….and with these solutions the concern becomes choosing wisely.  Everyone will have a uniq perspective on this given their line of business and network needs.  One size does not fit all.

With SDN/NFV this is like a snow-ball rolling down a mountain, it’s gaining momentum and gaining in size.  Managed service providers and hosting providers have capitalized on how to operate with SDN/NFV.  Network service providers are looking to capitalize, with some Tier 1 services providers already implementing SDN/NFV.  I see programming as a corner stone and I see networking know-how has a corner stone.  Evolving with the industry is a requirement for success.

So, having written the above, I’m off now to delve into cloud image creation.

  1. I will say the immediate exception I see here is the residential gateway (RG) devices.  Manufactures in the market space appear willing to implement IPv6 solutions into their products; however they want a to know how may new orders can be placed.  If it is not immediately obvious what the problem is with this statement (new orders) then please consider there are millions of RG devices already deployed.  Does the existing deployed hardware of these RG devices support IPv6?  If do support IPv6, which transition protocols are supported?
