What we recommend Retransmit at the NAS(ideally) or its Local Proxy. Generally don’t retransmit at intermediary nodes. But you need to keep track at intermediaries because you need to use this information in making failover decisions. Use Dynamic Retransmit Timeout (RTO) RTO based on RFC 2988 which uses RTT. Track RTO for each destination not the next hop proxy. Difficult because we don’t always know the criteria used to route packets at proxy servers. |
