Hi
@oibrak!
HPE Comware-based switches have fast forwarding feature:
Fast forwarding reduces route lookup time and improves packet forwarding efficiency by using a high-speed cache and data-flow-based technology. It identifies a data flow by using the following fields: source IP address, source port number, destination IP address, destination port number, and protocol number. After a flow's first packet is forwarded through the routing table, fast forwarding creates an entry and uses the entry to forward subsequent packets of the flow.It can be tweaked a little bit, but no many options are available. More info you can find in an 'IP Services" Config guide for respective platform, for example here is such guide for HPE 5940 -
https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=a00077572en_us , page 149.
AOS and AOS-CX switches should have similar feature, but I am not so familiar with those devices.

Hello All,
How L3 switches in the world of HP is handling packet fast forwarding at the hardware level ? For sure high range products are not switching packets with process switching. In other words, cisco have addressed this issue by designing CEF. How HPE have done it ? is there any standard or an RFC that is addressing packet fast forwarding on hardware level. Thank you.
