1-1. What is Network?
What is Network ???– a stuff that is consisted by nodes and
routes, there is flow in it.
f Wiki difrom Wikipedia…Human networks
Business network, Entrepreneurial network, Social networkEconomic network, Old boy network,
MediaRadio network, Television network,
TechnologyElectrical networkComputer network, Telecommunications network, Energy transmission and distribution networks
Focus on “computer network” !
Definition of Network in General
C i d b h h d l• Consisted by more than three nodes, alsopossible to communicate each other
“Non-Network”
“Point to Point”• “Point to Point”• Communication between two nodes
e.g. RS232, AES/EBU, MADI etc.
Criterion for separation?p
AES/EBU is Point to Point• AES/EBU is Point to Pointbut… utilizing with matrix router, it works as Network g
• Computer Network is…connection PC and switch is Point to Point
�we call its mass ”Network”�
There is no clear criterion...
But, the separation helps to understandfeatures of a format
Pros / Cons
• “Point to Point” style format has…E t lik l i i– Easy to use, like analog wiring
– Less flexibility comparing “Network”
• “Network” style format hasNetwork style format has…– More flexibility comparing “Point to Point”
S ti d IT kill ( diffi lt)– Sometimes, needs IT skill (more difficult)

• “IN” means audio flow from Yamaha device to EtherSound
• Clear “LOOP BACK ON” before starting to design configuration. Use “force to Mono direction”.
• Clear “TUNNELING ON” before starting to design configuration.
