OSI Model :

-

 



The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and implement networking protocols. It divides the networking process into seven distinct layers, each with specific functions. Here’s a brief overview of each layer:

  1. Physical Layer (Layer 1):

    • Function: Transmits raw bitstreams over a physical medium.
    • Components: Cables, switches, and the electrical/optical signals that carry data.

  2. Data Link Layer (Layer 2):

    • Function: Provides node-to-node data transfer and handles error correction from the physical layer.
    • Components: MAC addresses, switches, and protocols like Ethernet.

  3. Network Layer (Layer 3):

    • Function: Determines how data is sent to the recipient across multiple networks.
    • Components: IP addresses, routers, and protocols like IP (Internet Protocol).

  4. Transport Layer (Layer 4):

    • Function: Ensures complete data transfer and error recovery.
    • Components: TCP (Transmission Control Protocol), UDP (User Datagram Protocol).

  5. Session Layer (Layer 5):

    • Function: Manages sessions or connections between applications.
    • Components: Session establishment, maintenance, and termination.

  6. Presentation Layer (Layer 6):

    • Function: Translates data formats and manages data encryption and compression.
    • Components: Syntax and semantics of the information transmitted.

  7. Application Layer (Layer 7):

    • Function: Provides network services directly to end-user applications.
    • Components: Protocols like HTTP, FTP, SMTP.

This model helps in troubleshooting and designing networks by allowing professionals to isolate problems to specific layers. Understanding these layers aids in grasping how different protocols interact and function within a network.

Gigabit Ethernet is key when there is a mine of information

-

Continuous, reliable communications are essential for the success of mining operations. They enable the transfer of crucial information across facilities, ensuring that fans, pumps, conveyors, and other key pieces of equipment operate correctly. When ineffective communications led to an increase in downtime at a mining complex in Mexico, CC-Link IE network technology offered a solid solution. When the (broadcast) storm is coming The facility utilises a Mitsubishi Electric MELSEC iQ-R PLC platform to control 35 variable frequency drives (VFDs), which in turn modulate the speed of fans, pumps and conveyors. While the automation components have been operating successfully for years, the mining complex was experiencing prolonged downtime associated with network failure. More precisely, approximately 20 hours were lost every month because of broadcast storms, data packet collisions, intermittent or even lost communications between enterprise level software and field devices. To address the

Network Virtualization

Image
Network virtualization is a process of separating the functions of a network into different components, such as the physical infrastructure and management and control software and allowing those functions to operate separately. In this process, the software is used to emulate the functionality of hardware components that are commonly part of a traditional network. Network services are decoupled from the physical hardware they run on. They can be used independently, making them perfect for any network device. With this shift to programmable networks, we can more flexibly provision networks, more securely manage them, and programmatically and dynamically manage them. Network virtualization simplifies life for network administrators by making it easier to move workloads, modify policies and applications, and avoid complex and time-consuming reconfigurations when performing these tasks. In addition, customers and business people need instant access to various content, services, and informa
