Corporate communications

 

At a corporate and business level internal (local and wide area) network connections generally use TCP/IP internetworking infrastructure but the data packets are securely sent from one location to another instead of into the public Internet cloud where they may go by any (generally unknown and unpredictable) route.  This is considerably more costly particularly over longer distances.  When such communications (including database interrogations) were exclusively text based they involved a small number of data bytes (see comments on file sizes above) but as employees have gained access to the Internet and files began to contain images logos and the like the volumes 'blew out'  crippling network speed and/or increasing data transfer costs. 

This has accelerated the trend to using the public, relatively free Internet to transmit corporate data. With an increase in the public bandwidth and an increase in the range of publicly available services, not supported on internal networks, this trend can be expected to continue.  This is expected to lead to a new business networking paradigm (embracing cloud computing) that will radically change business systems over the next ten years.

Conventional wide area networks that grew during the past decade may be replaced by cloud based communications.  In this environment local area networks (directly connected by dark fibre and/or copper – for example within a building or campus) will remain hardened against intrusion but will encompass an extranet or similar functionality that facilitates inter-node communications that allows users direct access to the cloud for such purposes as video conferencing and to use external cloud based business applications including market access and e-commerce.

These local networks will become autonomous nodes from the point of view of secure document storage data processing and security functions but more integrated through externally shared applications and data. The increasing use of the Internet and increasing spread of broadband communications will free these nodes from present geographical constraints.

South Korea & China

March 2016

 

 

South Korea

 

 

I hadn't written up our trip to South Korea (in March 2016) but Google Pictures gratuitously put an album together from my Cloud library so I was motivated to add a few words and put it up on my Website.  Normally I would use selected images to illustrate observations about a place visited.  This is the other way about, with a lot of images that I may not have otherwise chosen.  It requires you to go to the link below if you want to see pictures. You may find some of the images interesting and want to by-pass others quickly. Your choice. In addition to the album, Google generated a short movie in an 8mm style - complete with dust flecks. You can see this by clicking the last frame, at the bottom of the album.

A few days in Seoul were followed by travels around the country, helpfully illustrated in the album by Google generated maps: a picture is worth a thousand words; ending back in Seoul before spending a few days in China on the way home to OZ.

The Fukushima Nuclear Crisis

 

 

Japan has 55 nuclear reactors at 19 sites.  Two more are under construction and another twelve are in the advanced planning stage.  Net Generating capacity is around 50 GW providing around 30% of the country's electricity (more here).  

As a result of Japan’s largest earthquake in history on March 11 and subsequent tsunami all reactors shut down automatically as they were designed to do but cooling systems associated with two sites had been damaged. 

Three reactor sites are adjacent to the earthquake epicentre and two were in the direct path of the tsunami.  The Fukushima-Daiichi plant belonging to Tokyo Electric Power Company was particularly hard hit.  It lost all grid connections, providing electricity, and its backup power plant was seriously damaged.
