What is Web 2.0?

• Web 2.0 is the business revolution in the
  computer industry caused by the move to the
  Internet as a platform, and an attempt to
  understand the rules for success on that new
  platform
• Tim O-Reilly speaking at Web 2.0 conference in
  2004
• However Tim Berners-Lee, inventor of the World
  Wide Web, has questioned whether one can use the
  term in any meaningful way, since many of the
  technological components of Web 2.0 have existed
  since the early days of the Web

What is Web 2.0? (continued)

• 2008 best effort push share something
  Internet
• Web 2.0 What You Need Is What You Get (2012?)
• (Gartner IT Summit 2008)
• Requires sophisticated federation between
  autonomous (non-integrated) systems to enable web
  based services to provide intelligent
  contextualisation based on knowing who and where
  you are and role you are acting in (work roles,
  home and leisure)

4
WEB 2.0 and the NHS (short term)

• The NHS will increase its business use of
  Internet based services for important but
  non-critical services
• The N3 and the N3 Internet Gateway will need to
  evolve to support the NHSs increasing business
  requirements for Internet Connectivity
• For the NHS Internet treated as best effort only
  is no longer appropriate in 2009

5
New Enhanced N3 Internet Gateway

• Enhancements to the existing N3 Internet Gateway
  will provided the following new features
• HTTP v1.1 Compression
• URL Categorisation
• Gold, Silver and Bronze differential service
• MACH5 Acceleration

6
HTTP v1.1 Compression

• Is a method of significantly reducing the amount
  of N3 resources consumed when users access
  Internet services and can increase the page
  display speed
• Compression of HTTP content occurs on the web
  server (where configured)
• Content is transmitted in a compressed format
• Content is uncompressed transparently on the
  receiving client browser with negligible impact
  on performance

7
HTTP v1.1 Compression

• An enhanced N3 Internet Gateway will allow
  existing compressed traffic to pass onto N3,
  making a bandwidth saving at the gateway and
  across the N3
• Existing uncompressed traffic from compatible
  sources on the internet will also be compressed
  by the enhanced gateway
• The N3 Customer can benefit from further
  bandwidth savings at their CPE by ensuring local
  clients, proxies and caches are configured for
  HTTP v1.1 compression

8
URL Categorisation

• The N3 solution is based on the Blue Coat Web
  Filter (BCWF) categorisation engine, features
  include
• 15 million website ratings of billions of web
  pages
• Continuous database updates from WebPulse
  community
• 61 pre-defined categories
• Includes Dynamic Real-Time Rating (DRTR), a
  patented technology that can instantly categorise
  Web sites when a user attempts to access them.

URL Categorisation

• The enhanced N3 Internet Gateway will enable
• Enhanced level of security, helping to prevent
  Internet attacks from spyware, phishing,
  peer-to-peer (P2P) traffic, viral content etc
• Blocking by category
• Restricted access to content by time of day
• Partition available bandwidth at the Internet
  Gateway to a hierarchy of prioritisation levels
  (e.g. Gold, Silver, Bronze)

MACH5 Acceleration

• The enhanced N3 Internet Gateway will support
  local NHS organisations who choose to deploy
  local internet proxies solution aimed at further
  improving Internet performance for their users
  through
• MACH5 functionality between the internet gateway
  and customer end sites that deploy compatible
  Blue Coat technology
• Potential for Gold service for customers
  employing an agreed AUP

12
MACH5 Acceleration

• The proprietary acceleration technology from Blue
  Coat provides
• Bandwidth Management
• Protocol Optimisation
• Object Caching
• Byte Caching
• Compression
