Question

### Virtual Circuit-Switched Network:

This image depicts a network setup using virtual circuit switching with a series of hosts and switches. The network includes the following components:

- **Hosts:**
- Host A
- Host B
- Host C
- Host D
- Host E
- Host F
- Host G
- Host H
- Host I
- Host J

- **Switches:**
- Switch 1
- Switch 2
- Switch 3

Each switch has numbered ports connected to various hosts or other switches.

### Task:

**Objective:**
Create virtual circuit tables for all switches after establishing specific connections. These tables should reflect the following criteria:

- The sequence of connections is cumulative; earlier connections remain active when new ones are added.
- VCIs (Virtual Circuit Identifiers) are assigned by choosing the lowest unused VCI on each link, starting from 0.
- A VCI is consumed for both directions of a virtual circuit.

**Connections to establish:**

1. A connects to B
2. C connects to G
3. B connects to A
4. F connects to A

This setup requires careful planning of VCIs to maintain the integrity and efficiency of the network connections.

Follow-up Question

This is the same question , not different question , please answer the last one too.

Give the virtual circuit tables for all the switches after each of the following connections is established. Assume that the sequence of connections is cumulative; that is, the first connection is still up when the second connection is established, and so on. Also assume that the VCI assignment always picks the lowest unused VCI on each link, starting with 0, and that a VCI is consumed for both directions of a virtual circuit.

F connects to A
