Introduction

• There is a problem in communication network
  which has many user requirements to services.
  The problem is

( Receives Junk )
( Receives High Quality )
3
KISS is The Solution
To solve that problem, we can consider a good
solution so called KISS ( communication
infrastructure for streamingservices )

• KISS takes the 128 kBit/s (CD Quality) and
  reduces it to a 32 kBit/s (FM Quality)

• This reduced quality stream data is sent to the
  client in the low bandwidth network

• This happens without the server or the client
  knowing it

--- HOW DOES IT WORKS ??? ---

Model Scenario
KISS consists of the following three parts

• Network Access Point (NAP) NAP Organizes the
  internal KISS network and constitutes an
  access point for end applications

• Service Agent (SA) SA supplies additional
  content-independent services such as the
  conversion of data formats (transcoding, etc) in
  the KISS context

• KISS-API for communication with end application
  (EA) KISS-API constitutes the programming
  interface for EAs

Format A
Format B

SCENARIO STEP 1(due to the figure before)

• No multimedia data have been transmitted yet

7
SCENARIO STEP 2

• Server doesnt know who has requested its service

Architecture of KISS

• The Connection between EA and NAP consists of
  - Bi-directional control link - Arbitrary
  number of data link (usually uni-directional)

• Control communication is integrated into the
  Client-Network- Interface (CNI), which also
  describes NAP localization

11

• Behind an NAP, CNI is extended to the
  Network-Network- Interface (NNI), which adds
  methods such as requesting and announcing
  service information

SA function

• SA can adapt the data rate of multimedia stream
  to the clients bandwidth

• SA can convert a multimedia stream from coding
  format A to coding format B

SA Extension

• Tunneling of Firewall
• Interconnection of several KISS clouds
• Synchronization of several streams
• Mixing several multimedia streams to a single
  one
• Forward Error Correction (FEC)
• Unicast-Multicast Conversion
