10 fundamental points should know as Tx or IP Engineer

Transport Networks
1

  1. Ethernet: A widely used LAN technology that uses frames to transmit data between devices in a network, typically over cables.

  2. STP (Spanning Tree Protocol): A protocol that prevents loops in a switched Ethernet network by creating a loop-free logical topology.

  3. VLAN (Virtual LAN): A network configuration that logically segments a network into multiple, isolated broadcast domains.

  4. CSMA/CA: A protocol used in wireless networks to avoid collisions by detecting free transmission channels before sending data.

  5. Route Reflector: A BGP mechanism that reduces the number of required peer-to-peer connections by reflecting routes from clients to other routers.

  6. Split Horizon: A routing technique that prevents routing loops by ensuring that routes learned from an interface are not advertised back on the same interface.

  7. Subnetting: The practice of dividing a larger IP network into smaller, more manageable sub-networks.

  8. Summarization: A technique that consolidates multiple routes into a single, broader route to optimize routing efficiency.

  9. TCP (Transmission Control Protocol): A connection-oriented protocol ensuring reliable data transmission between devices with error checking and flow control.

  10. UDP (User Datagram Protocol): A connectionless protocol that sends data without guaranteeing delivery or order, used for speed-critical applications.
