AI Technical Summary
Technical Problem
Deadlock in the network prevents packets from being forwarded normally, especially when the buffers of multiple network nodes with circular dependencies are empty.
Method used
By carrying a first identifier in the message and determining a second identifier according to the forwarding rules, the forwarding path of the message is adjusted to ensure the reasonable use of the cache space and avoid insufficient resources affecting forwarding.
Benefits of technology
It enables normal message forwarding, improves the flexibility and reliability of message forwarding, and avoids deadlock.

Abstract
The present application provides a packet forwarding method, an information acquisition method, apparatuses and systems. In the packet forwarding process, on the basis of a first identifier carried in a packet and forwarding rules, a network device determines a cache space used for packet forwarding. Since the first identifier is associated with a region divided on the basis of a plurality of packet forwarding paths in a network, when the first identifier is determined, the plurality of packet forwarding paths in the network are considered, and when a deadlock phenomenon occurs, the packet forwarding paths can be adjusted, so that normal packet forwarding is ensured, and the flexibility of packet forwarding is improved.
