Could you advise a example for the RTR? Like 100GE, the packet buffer, what is the RTR needed?
Besides, is RTR the stander metrix for SRAM performance?
For a 100GE interface, the packet rate (R) would be 150MP/s.
For a Packet buffer application,the random transaction rate range is (4R-6R) MT/s where R is the Packet rate. This comes upto 600-900MT/s
Why do you need to multiply the Packet Rate by 4 or 6 ? where does this come from?
The Random Transaction Rate = Packet Rate (R) x (# of Accesses/packet)
The # of Accesses/packet for Packet Buffer application ranges between 4 and 6.Hence the Packet Rate (R) is multiplied by this factor.
that may be true for the packet buffer function. But what about statistics? Look up tables, scheduling?
Are there others?
Below are the RTR for the following applications.
Statitics : 2R MT/s
Lookup tables :4R-8R MT/s
Scheduling :: 2R MT/s
