Routing

Hi,

Does J2350 have ASIC firewall implementation? How much stateless firewall and policying will it handle? Will it affect forward latency?

Thanks.

The J-series do not use the asic based forwarding but software based to keep the cost down.  There is an option for Hardware based encryption that can improve performance for encrypted traffic.

You can see the maximum throughput for the various types of traffic in the specification sheet.

 I know it don't have asic for forwarding, does that means it doesn't have it for filtering as well? 

What's the latency effect on firewall rules?

The only hardware based processing availabe in the J-series is the optional encryption.  All other processing occurs in software.

I don't know if there is any latency effect on stateless firewalls.  I've never seen a change in applying one.  But I have only used small filters.  I suppose it is theoretically possible that a very large filter and high traffic would introduce some latency.

But with the J-series you are more likely to hit throughput limits for the traffic types that would affect performance before this would.  Take a look at the max specs in the data sheet for they type of traffic you will be processing.
