Achieves New Levels of Performance

• A quantum leap in XML bandwidth optimization
• Simultaneously optimizes
• Network bandwidth, throughput and scalability
• Server scalability, throughput and CPU
  utilization
• Device battery life, storage, heat and
  responsiveness
• Data center power consumption, heat, bandwidth
• Requires no special hardware or proprietary
  interfaces

Traditional compression adds processing overhead
for compression/decompression
20
FAQHow much overhead does Efficient XML
introduce?

• It depends on your implementation
• Efficient XML 1.0 was a little slower than
  gzipped XML
• Efficient XML 2.0 was sometimes slower, sometimes
  faster than XML
• Efficient XML 3.0 was up to 90x faster than XML
• So, with a fast implementation, it can actually
  decrease overhead

Efficient XML 3.0 Processing Speed Examples
48x faster!
7x faster!
30x faster!
21
FAQWill Efficient XML break compatibility with
plain-old-XML?

• No
• Efficient XML 3.0 detects and uses EXI when
  available and automatically falls-back to XML
  otherwise
• Clients that dont support EXI never receive it

Server
Client
I support XML and EXI
Im sending you EXI
Client

22
FAQDo I have to change my code to use Efficient
XML?

• No.
• Efficient XML plug-ins add EXI natively to web
  service platforms
• Efficient XML proxies (HTTP, TCP and UDP) add EXI
  to existing applications

Integration using Efficient XML Integration Kits
requires no code modifications
23
FAQ Can I view EXI with standard XML tools?

• Yes. With appropriate plug-ins and converters.

This kind of transparency and tool support makes
testing, debugging and using EXI far easier than
other binary formats
24
FAQDoes Efficient XML work with XML Security?

• Yes. Unlike most XML optimization technologies,
  Efficient XML was designed to work with existing
  XML Security standards and libraries, including
  XML Digital Signatures and XML Encryption.
• AgileDelta also provides Efficient XML Digital
  Signature and Efficient XML Encryption products
  that leverage Efficient XML to eliminate
  well-known XML Security processing bottlenecks
  and increase the bandwidth efficiency of XML
  Security protocols.

What do we Mean by Efficiency?

• Dictionary definition
• Acting or producing effectively with a minimum of
  waste, expense, or unnecessary effort.
• Exhibiting a high ratio of output results to
  input resources
• Mathematical definition
• Results include web pages, web service calls,
  messages, etc.
• Resources include bandwidth, processor cycles,
  memory (code, data and heap limits), battery
  life, disk space, etc.
• So, for example, system A is more efficient than
  system B if
• A produces the same result as B using fewer
  resources
• A produces more results than B using the same
  resources
• A produces more results than B using fewer
  resources

27
Why Worry About Efficiency?

• Resources cost money
• Bandwidth, processor power, memory (code, data
  and heap), battery life, disk space, etc.
• Less resources better cost / performance ratio
  lower prices and/or
  more profit
• Many systems dont have resources to spare
• Cost sensitive, mass market devices mobile
  handsets, set-top boxes, consumer electronics,
  game consoles, automobiles, etc.
• Physical constraints battery life, size, weight,
  heat, etc.
• Less resources cheaper, smaller, lighter,
  cooler, etc.
• Faster more scalable without more hardware

Theoretical Basis for Efficient XML

• Information theory (1948 Claude Shannon)
• Provides formalisms for defining theoretic
  optimal encoding
• Defines one bit as amount of data required to
  differentiate between two equally likely
  alternatives
• Tells us log2(1 / p1) bits required for data with
  probability p1
• Data probabilities are a function of our
  knowledge of the data
• More knowledge fewer bits
• Knowledge about data can be gathered
• Dynamically via data analysis
• Statically e.g. via schemas
• Schemas define what is likely to occur, not the
  entire universe of discourse!

32
Efficient XML Approach

• Generalized Algorithm
• Use a grammar to determine the language
  constructs (not characters) most likely to occur
  at any given point in the stream
• Assign variable-length codes to represent most
  likely language constructs in fewer bits
• Concept works for any regular language that can
  be described by a grammar (e.g., XML, HTTP, CORBA
  IDL, Java, )
• Efficient XML is specialized for XML
• Built-in knowledge of XML grammar
• Built-in knowledge of XML data types
• Can augment grammar and type knowledge using
  schemas
• Refines grammar knowledge based on experience
• Does not require accurate, complete or current
  schemas (schemas describe things that are likely
  to occur)
