RouterBOARD 44G throughput

How do you expect to get “Outstanding performance and functionality”, when the maximum throughput of PCI slot is only 133MB/s (1064Mbit/s). You are selling the product whitch is trying to put 512MB/s (4096Mbit/s) in 133MB/s pipe. Am I wrong or there is some king off miracle to get this to work?

this is the maximum performance your system can carry. of course it’s amazing :slight_smile:

yes there are limitations in PCI, that is known.

for the first time i read this topic , i dissapointed !!! what ??? i have RB44 , so i cant go higher than 1 Mb/s ??? looooooooool
then i relized it was 1064Mb/s …
thank god ..

So, is there any way to properly use 44G, or we have to wait for RB1000? Do You have estimated arrival time of rb1000?

what do you mean by properly? this card allows you to push the maximum speed your system supports, there is no other interface that can push more speed with your existing system because of PCI bus limitations. if you want more speed, you should wait for a PCI express interface (which will require you to buy a new pc), but as far as the PCI standard is concerned, this is the absolute maximum you will ever get. how’s that for amazing?

I am a little confused. What does the RB1000 have to do with the 44G?

Also a full duplex connection with 4x 1Gb/sec is 1GB/sec or 8Gb/sec

Also Normis. I have a pc today with PCI Express. I also have a a few of PCI-X 64bit/133mhz PCI bus 1GB/sec, and tons of 64bit/33mhz bus servers 256MB/sec.

So is the deal with the RB1000 going to have a PCI Express slot and a simultaneous release with the 44G-PCI-Expresss?

Also, I thought some of the intelligent multiple Ethernet NICS support port-to-port transfers (across same card) without ever using the PCI bus. Does this particular card work that way?

you have misunderstood this discussion. the problem is thar RB44G is a PCI card and not a PCI-X card, so consequently it is limited by the PCI bus speed. This has nothing to do with RB1000, except that it will also have a Gigabit port

how does a port-to-port transfer help on a router? If you want a switch/hub, you don’t need RouterOS

Ugh, your right Normis. I wasn’t thinking straight.

Interestingly, AFAIK a lot of commercial L3 routing switches use hardware switch fabric for L2 switching and then a CPU to do the L3 functions including routing, on the same platform. Examples of the silicon are Broadcom StrataXGS etc. and then a software routing stack is added to run on a CPU such as MIPS, PowerPC etc.
These can manage to get higher throughput than “software-only” routers for high port counts because L2 traffic doesn’t go through the CPU.
Not an issue for software-based routers as ROS can do full-speed Gigabit etc for lower port counts - but for larger port counts (12-24 ports) the hardware solutions can scale better. Depends on the split of L2/L3 traffic.
Different style of solution I guess - horses for courses -

Yeah you’re right, but i think that 4x GbE PCI based card is more marketing than the hardware.
Even if we want to have only one good gigabit port with performance on the edge (Ageregated 300Mbps+ ), using Realtek chipset isn’t the right choise i think.
I spent much time trying to find good (and cheap) replacement of Intel Ethernet cards so i’ve tested many cards/chipsets and always get back to the intel…
Mikrotik should consider moving his 4x GbE Card into PCI-Express (which is bulid in every current motherboard) then irq bottleneck won’t affect performance, after driver tunning we can have good Ethernet module…

you don’t need to wait for mikrotik .
I believe it is already available from Intel

If i want to have high performance product i’ll use intel, but sometimes i want good performance for reasonable price…

maybe this one more reasonable??
