* Question
| What is the priority-based cache management strategy? |
* Answer
| The cache resources carried by the nodes in the delay network are limited. Therefore, the cleanup strategy and the priority of message forwarding when the cache space overflows often affect the performance of the routing algorithm.Use C (M) to indicate the hop count of the message M, and use three (M indicates the time when the message M has survived, TTL indicates the time when the message can survive (ie, the lifetime of the message), and the number of nodes in the network is represented by NC.The longer the message M has survived, the more r (the value of M is, and the final priority is UP (the value of M is smaller).To some extent, the number of times of forwarding each message in the cache is balanced, and some messages are never available for forwarding. |
