Packet Switching Types Explained | Generated by AI
In packet switching networks, there are two main types of packet switching:
- Datagram Packet Switching (数据报分组交换)
- Each packet is treated independently.
- Packets may take different paths to reach the destination.
- No pre-established path or connection is required.
- Suitable for connectionless communication (e.g., IP networks).
- Virtual Circuit Packet Switching (虚电路分组交换)
- A logical connection (virtual circuit) is established before data transfer.
- All packets follow the same path.
- Packets are delivered in order.
- Suitable for connection-oriented communication (e.g., ATM networks).
Key Difference:
- Datagram: No fixed path, packets are routed independently.
- Virtual Circuit: Fixed path, packets follow the same route, ensuring ordered delivery.
So, the blank in your question is correctly filled with “虚电路” (Virtual Circuit).
