FastL4 Buffer reassemble size

Hey cyber123, reassembly actually occurs at the IP layer, so fastL4 doesn't have anything to do with that, just allows the reassembly to occur if necessary.

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

 

 

Courtesy of the development team, there can be no more than 4096 fragments in the system at any one time.
