I had a meeting last week with Cisco. They told me that if you want to do
100 Mbits routing, you shoud really have a router that is supporting 100 Mbits routing. For example I chose the Cisco 2821 that has 2 interfaces
10/100 mbits. They told me that this router is not going to support it. They adviced me to take the Cisco 3845. It is much expensive. So I don't know if it is just bullshit or true.
It isn't bullshit. The 2821 is designed to support a small number of T1 lines, not anywhere close to 100 Mb/s.
2821: raw performance 87.04 megabits/s -- which would give you less than 45 megabits/s each way in a full duplex environment.
"As you add ACL's, encryption, compression, etc - performance will decline signficantly from the given numbers [...]"
Note that the 87.04 megabits/s is with 64 byte packets, and that your effective performance would increase if a significant number of your packets were longer than the minimum size. It is common for packets to be either very short (icmp, TCP ACK) or long (full TCP packets); in many environments, the average sized packet is about 256 bytes. If you multiply the raw performance by 4, on paper you get enough to route 100 megabits/ full duplex, but the professional tests that have been done show that the 2821 is, under realistic traffic loads, best suited for what Cisco markets it for -- 2 T1's or so.
It all depends on WHAT they actually said or what YOU thought they said. A 2821 will never do 100Mb/s of traffic Routing, but it will pass data at 100Mb/s, and it will do that on multiple interfaces. HOWEVER, there is a significant difference between simply passing traffic and making routing decisions based on the contents of that traffic.
The bottom line is that if you really do have a genuine need to
100Mb/s worth of ROUTING, then you really do need the bigger box.
there is a related point which is important - one reason these boxes are expensive is that they are software driven routers.
these days software routers are optimised to drive WANs, or where you need complex processing that cant all be done in hardware
if all you need is good IP performance with LAN interfaces, then you may be better off using a layer 3 switch where IP forwarding is done in hardware - a 24 port 10/100 Catalyst 3560 costs less than 1/2 a 3845 - but is higher thruput on Ethernet and there are 24 10/100 ports, not 2.
Your phone number is NOT 951-whatever, except perhaps to a small portion of California. Your phone number is 1-951-whatever within the North American Numbering Plan (NANP), and outside of the NANP is +1-951-whatever.
This is an international newsgroup, and you were offering something to someone who is not located anywhere near you. If you would prefer that your company not be perceived as only knowing how to do business in a small part of California, then I would recommend that your postings use the international version of your phone number instead of your only-works-in-a-small-area phone number.
Specifying the currency on prices helps too: the $ symbol is used by several countries, so specifying US or USD helps to reassure people that you deal internationally regularily and know about matters such as international payment instruments, good international shippers, cryptography export restrictions, and the like.
I stated that the prices are in USD after your initial question, which I figured would tell people that I am located in the States. True, I did not specify 1.951.xxx.yyyy, but once again i assumed that someone calling international to the united states would know what they need to punch in.
I am sorry I did not take this into consideration, but normally when dealing with international customers, they have been able to deduce the full phone number when i just have 951.xxx.yyyy since they know i am located in the US.
I just copied my contact information from my emails, and that seems to have worked for all my previous international dealings. But i will take your advice into consideration and will write the international version when posting to this group.
