Perl, Python and ASP (Active Server Pages). In comparison, Web 2.0 is “Network as Platform”, or the
“participatory web”. It uses some or all of the technologies of Web 1.0, plus new things such as
(and the world’s biggest Wiki, the
), blogging sites, social networking sites like
video publishing sites like
, photographic snapshot publishing sites like
, Google Maps, etc.
Andrew Keen (British-American entrepreneur and author) claims that Web 2.0 has created a cult of
digital narcissism and amateurism, which undermines the very notion of expertise. It allows
to share their own opinions and content, regardless of their talent, knowledge, credentials, or
bias. It is “creating an endless digital forest of mediocrity: uninformed political commentary, unseemly
home videos, embarrassingly amateurish music, unreadable poems, essays and novels.” He also says
that Wikipedia is full of “mistakes, half truths and misunderstandings”. Perhaps Web 2.0 has made it
easy for the mass public to participate. Tim Berners-Lee’s take on Web 2.0, is that it is just a “piece of
jargon”. In the finest tradition of Web 2.0 these comments, which were found in the Wikipedia article on
Web 2.0, probably include some mistakes, half-truths and misunderstandings.
Basically, Web 2.0 does not introduce any revolutionary new technology or protocols; it is more a
refinement of what was already being done on the web, in combination with a new emphasis on end-
users becoming not just passive consumers, but also producers of web content. The Second Internet will
actually help make Web 2.0 work better, as it removes the barriers that have existed in the First Internet
since the introduction of NAT to anyone becoming a producer of content. If anything, on the Second
Internet, these trends will be taken even further by decentralizing things. There will be no need for
centralized sites like YouTube or Flickr to publish your content, just more sophisticated search engines
or directories that will allow people to locate content that will be scattered all over the world. Perhaps
that will be the characterizing feature of
Web 2.0 is a really minor thing compared to the Second Internet. What isn’t pure marketing hype is an
evolutionary development of
of the major services (the
World Wide Web
) out of perhaps a dozen
that the Second Internet will be capable of hosting. These include global telephony, newer forms of
communication like decentralized instant messaging, major new Peer to Peer applications (not just file
sharing), global broadcast entertainment via multicast IPTV, connectivity between essentially all
consumer electronic products, personal healthcare sensor nets, smart building sensor nets, etc.
1.7 – Whatever Happened to IPv5?
Two of the common questions people ask when they start reading about IPv6 is “If it’s the next version
, why isn’t it called
?” and “What happened to the
versions of IP?”
There is a four bit field in every IP packet header that contains the IP version number in binary. In IPv4,
that field contains the binary value 0100 (4 in decimal) in every packet. An earlier protocol (defined in
RFC 1190, “Experimental Internet Stream Protocol, Version 2 (ST-II)”, October 1990) used the binary
pattern 0101 (5 in decimal) in the IP version field of the packet header. The Internet Stream Protocol
was not really a replacement for IPv4, and isn’t even used today, but unfortunately the binary pattern
0101 was allocated to it. The next available bit pattern was 0110 binary (6 in decimal). It would be even
more embarrassing than explaining that there was no IPv5, to explain why the IP Version Number field
for IPv5 contained the value 6. Now you know.
