Network Architectures, OSI, and the TCP/IP Legacy

I just thought I’d follow on with a favourite topic…….networks and communications…..before the contest closes.  I posted aboutstandards and networking last year, and I followed up with another postabout John Day’s book called Patterns in Network Architecture recently.

Networks (i.e. pervasive communications) are also key to success infighting large scale health issues such as Swine Flu (my last post implies this).

Last year we also blogged on the topic of Cloud Computing.  At that time I raised the ugly topic of security and privacy – I’ve recently been seing articles that seem to prove my point.  Also, the big players are seeing it as a new market segment and are aiming for Gorilla status (see the Gorilla Game by Geoffrey Moore).

We were also asked to blog on the topic of “legacy networks” in thecontest this year.  I don’t think many posts were forthcoming,however.  I was wondering what would be considered as legacy thesedays.  When I was involved with IBM’s SNA it was the simple teletypecircuit that was legacy; then TCP/IPV4 came along and eventually madeOSI, SNA and DECnet all legacy.  Now its perhaps IPv6 that is trying tobecome the “legacy-maker”.  And what might be next – The Network IPCModel from John Day’s book may provide clues as to the future ofnetworking.

Here’s a few topics that would be worth exploring, and which will have to wait for a future post (if time allows):

-  Types of interaction (one-way, two-way, small message, realtime vs. batch transfer), etc.

-  Clouds as network elements (inter-cloud communications, addresses for clouds, management of clouds

-  Processing in the network (or only at endpoints)

-  Naming and addressing and directories and name servers and more

-  Management of distributed Web 2 systems in general (I hated itwhen I couldn’t access the Change Delivery Option for my local courierthe other day)

-  Layering updated (is layering still a good model?)

All in all, this is fertile ground for quite a few posts……..perhapsI will try to move some of this over to the “Ahead of the curve” areanext month.  Let me know if you have any favourite topics of your ownthat deserve airplay.

I'm a IT management consultant. I began my career in railways and banks after which I took up the consulting challenge! I try to keep in touch with a lot of different I&IT topics but I'm usually working in areas that involve service management and procurement. I'm into developing ISO standards, current in the area of cloud computing (ISO JTC1/SC38). I'm also starting to get more interested in networking history, so I guess I'm starting to look backwards as well as forwards! My homepage is but I am found more here.
