Hello,

 

 

 

 

I want to use a fastL4 custom profile and enable the parameter “Reassemble IP Fragments”. But I need to know:

 

 

- What is the maximum number of fragment / amount of data that the system buffers for one IP packet?

 

 

- What is the maximum amount of data that the system buffers for all IP packets?

 

 

 

 

Customer context:

 

 

- My customer established one UDP session: Source IP, Destination IP, Source port, Destination port are identical, the difference can be made only by an applicative Layer (SIP). So I have only one Virtual session on my Load-Balancer.

 

 

- The UDP payload can reach 5 KBytes.

 

 

- The MTU is dynamical (PMTU_discovery enable on F5).

 

 

- The customer traffic is around 30 Mbits/s

 

 

 

 

Thank you for your help
