NETWORKING

Network is a collection of computers and devices interconnected by communication channels for sharing of resources.

It’s performance is measured in bits per second (bps).

It helps in easy & efficient communication

Sharing of information

NETWORKING

Ethernet cable Network Switch Ethernet Hub

VLAN

It is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain

A VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not located on the

same network switch.

SWITCHES AND ROUTERS

Layer 2 switches uses MAC address from NIC to decide where to forward the frames.

Layer 3 switches are route-caching and topology based.

A router is a device that forwards data packets between telecommunication networks, creating an overlay internetwork.

When data comes in on one of the lines, the router reads the address information in the packet to determine its ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey or drops the packet.

ADVANTAGES OF PROPOSED NETWORK

In the old network, if connection between the main L3 switch and IOGPT network, gets any damage, IOGPT will be disconnected from the network. This problem is solved by connecting indirectly to the main server through IOET which will be used as a redundant line.

Data flowing to the wings of IOGPT cannot be controlled in the previous network. Adding a L3 switch between the main server and IOGPT network will give the administrator power to control the flow of data in the network .

An additional L3 switch is added and each department of IOGPT is connected to both the L3 switches, this will reduce the load on a single line and also serve as a backup during the failure of any line.

This will also help when one of the L3 switches itself gets corrupted or damaged. Two lines are laid between the two L3 switches for backup.

SERVERS

A computer program running to serve the needs or requests of other programs (referred to in this context as “clients”) which may or may not be running on the same computer.

Types Application server-data & code integrity, centralized config, security File server-shared disk access, dedicated server, non-dedicated server Proxy server-security, to cache web pages frm web server,access policy Database server-to keep databases Web server-virtual hosting using 1 IP address, large file support

SCADASupervisory Control and Data

Acquisition

It collects data from various sensors at a plant or factory at remote places and then send this data to a central computer, which controls and manages data.

Supervisory: Operator/s, engineer/s, supervisor/s, etc Control: Monitoring, Limited, Telemetry,

Remote/Local Data acquisition: Access and acquire information/data from

the equipment. Sends it to different sites through telemetry in the required form.

ADVANTAGES

Saves Time and Money Less traveling for workers (Jeep, Boat, ) Reduces man-power needs Increases production efficiency of a company Cost effective for power systems Saves energy Reliable Supervisory control over a particular system

CONCLUSION

Training has given me a hands on experience of the networking component and their interconnections.

I was able to see all the tools used for data acquisition from onshore as well as offshore platforms, and how this data is transported and interpreted/monitored at different locations.
