Questions about Data Packet Fragmentation Prevention Technology

1. How does monitoring PMTU values help prevent data packet fragmentation?

Monitoring PMTU values helps identify potential issues with data packet sizes that could lead to fragmentation, allowing for proactive rerouting to prevent this problem.

2. What are the benefits of statistical analysis of fragmentation rates in routing devices?

Statistical analysis of fragmentation rates helps in understanding the performance of egress links and data flows, enabling informed decisions on rerouting to prevent packet fragmentation.

Original Abstract Submitted

Techniques are described for avoiding data packet fragmentation in a routing device such as a router or network switch. Path Maximum Transport Unit (PMTU) values are monitored for a plurality of egress links of a networking device. A statistical analysis of fragmentation rates is performed. The statistical analysis can be performed on a per-link basis, per-flow basis or both per-link and per-flow basis. If the packet fragmentation rate of data flows through a particular egress link exceeds a determined threshold value, one or more data flows can be re-routed to a different egress link having a higher PMTU, thereby preventing data packet fragmentation.
