Troubleshooting Ethernet and Fragmentation Issues
... The Path MTU Discovery system (PMTU) was established to determine the smallest allowable MTU of any link on the current path between two hosts. The MTU size for the path between two hosts can vary since the routing may change over time. The path is not necessarily symmetric and can even vary for dif ...

Secure High-Throughput Multicast Routing in Wireless Mesh Networks
... In a typical high-throughput multicast protocol, nodes periodically send probes to their neighbors to measure the quality of their adjacent links. During route discovery, a node estimates the cost of the path by combining its own measured metric of adjacent links with the path cost accumulated on th ...
