我从RFC 3561 - AODV, page 11 中阅读了以下内容:
A destination node increments its own sequence number in two circumstances:
- Immediately before a node originates a route discovery, it MUST
increment its own sequence number. This prevents conflicts with
previously established reverse routes towards the originator of a
- Immediately before a destination node originates a RREP in
response to a RREQ, it MUST update its own sequence number to the
maximum of its current sequence number and the destination
我不明白递增序列号如何防止与先前建立的反向路由发生冲突;为什么这有帮助?另外,“它必须将自己的序列号更新为当前序列号的最大值”是什么意思,这个最大值是什么意思?
