SWITCHED NETWORKS

SWITCHED NETWORKS

1. These technologies enable real-time resource distribution among multiple people in remote sites, as if they were in the same physical location.

2. Increasing network complexity

   • These state-of-the-art networks must not only meet current expectations and equipment, they must also be able to integrate old platforms.

3. Elements of a converged network

   • Call control
   • Voice messaging
   • Mobility
   • Answering machine

4. Cisco Borderless Networks

5. Hierarchy in switched networks without borders

   • Hierarchy
   • Modularity
   • Resilience
   • Flexibility

6. Access layer

   • Represents the perimeter of the network, where campus network traffic enters or exits.

7. Distribution layer.

   • The distribution layer interacts between the access layer and the core layer to provide many important functions.

8. Central core layer

   • The primary purpose of the core layer is to provide fault isolation and high-speed backbone connectivity.

9. Function of switched networks

   • Quality of service
   • Additional security
   • Support for wireless connectivity and networking technology
   • Compatibility with new technologies such as IP telephony and mobility services

10. Form Factors

    • Cost
    • Density of ports
    • Supply
    • Reliability
    • Speed of the port
    • Speed of the port
    • Scalability

11. MAC address tables in connected switches

    • Paso 1: Aprendizaje: Examinar la dirección MAC de origen
    • Step 2: Forwarding: Examine the destination MAC address

12. Methods of forwarding the switch

    • Switching by cutting method
      • Send the plot before receiving it in its entirety.
    • Storage and Shipping Switching
      • Receive the full frame and calculate the CRC.

13. Domains of collisions

14. Domains of diffusion
