Because time is available after the sender finishes transmitting the data packet and before the sender finishes processing any received acknowledgment, the interval is used for transmitting more data. This is common when a hub that has multiple workstations is attached to a switch port or when ports are interconnected. Chinmay Shankar. Traffic Management for High-Speed Networks: Chapter 10 p.
Routers and Layer 3 switches use Layer 3 switching to switch packets. Layer 2 switches and bridges use Layer 2 switching to forward frames.
In these cases network traffic will travel across other networks and usually cannot be avoided. Symmetric switching provides switched connections between ports of similar bandwidth. The switch reads the destination MAC address on the incoming data frame and refers to the switching table. This is common when a hub that has multiple workstations is attached to a switch port or when ports are interconnected.
A similar process occurs when the transmission needs to pass through two switches, as shown in Figure 4-xx.
Host A transmits the frame to port 1 on Switch A. The switch then floods all ports with the incoming data frame, except for port 1. The data frame is forwarded to Switch B on Port 4. Switch B looks at the switching table and recognizes the MAC address. When Host F replies to Host A, the procedure is reversed. Switch A can now update the switching table by mapping Host F to Port 4. Switch B can now update the switching table by mapping Host A to Port 2.
Broadcast and multicast traffic is also forwarded out every port, except the port on which the traffic arrived. These BPDUs are considered inferior because they are generated from the designated switch that has lost its link to the root bridge. At least one port must be in VLAN 1 in order to manage the switch remotely. All other ports on the switch may be reassigned to alternate VLANs.

Presentation layer Layer 6 —This layer provides data representation and code formatting, along with the negotiation of data transfer syntax. It ensures that the data that arrives from the network can be used by the application, and it ensures that information sent by the application can be transmitted on the network.
