Internetwork Connections
• Repeaters
• Bridges
• Routers
• Gateways

Repeaters
• Connect two segments of the same LAN
• Simply amplify and retransmit the signal to the next segment.
• Repeaters connect different segments...but all segments form one LAN.

Bridges• Connect two networks.
• Bridge acts as a node as far as each network is concerned.
• More intelligent than repeaters and can reduce the traffic.

Routers
• Transfer data between different networks and route packets to the correct network to which they are attached.
• This is based on the Network layer (OSI Model).

Gateway• Connect networks which are totally dissimilar.
• There may be a need to translate all 7 OSI layers.
• High overhead and to be avoided where possible.
• Expensive and low performance.

Object division
• Consists of intelligent electronic devices (IEDs), modern, third-generation microprocessor based relays and/or remote terminal units (RTUs)
• The communications network :
• Nervous system of power system automation
• Ensures that raw data, processed information, and commands are relayed quickly, effectively and error-free among the various field instruments, IEDs and the SCADA system

SCADA master
SSupervisory upervisory CControl ontrol AAnd nd DData ata AAcquisitioncquisition
• Receives data and information from the field, decides what to do with it, stores it, and issues requests and/or commands to the remote devices
