3700 vs 3800 routers

Hi friends,

Given the options of 3700 vs 3800 series, it is a little confusing on which one to go for. I just wanted an answer to some questions:

3800 supports 1 GB DRAM. I am not able to foresee when I would need so much memory? Shouldn't the 3745 with 256 MB be just enough for the next 4-5 years? If you ask me my requirement currently, all I need is to use 3 Network modules (NM-2FE2W-V2, NM-8A/S X 2), WIC-2T x 2 cards and ISDN BRI S/T card. I dont have any requirement for voice and wireless. But I may need increased security later.

The pps rating for 3745 is 225 kpps and for 3800 is 350 - 500 pps. Does that really make a difference if all I need is WAN links of a max of 2 Mbps?
Is there any tool that tells me what is the roadmap for 3700 and

3800 series? I mean the expected lifecycle for 3700 and 3800 routers? Indformatrion like when is the 3700 likely to go end-iof-sale and the same with 3800 series.

Thanks a lot Gautam

3700s are likely to vanish before 3800s - when the 3800 was released well over a year ago, Cisco promised the 3700s would not be made end of life for at least 18 months - which is about now.

it is cheaper to WICs into the WIC slots than to put ports into modules. 3800s also support the async 4 / 8 port WICs - not sure if

3700s do.

3800 is touted as the 3700 replacement, so 3800 should have a longer production life (at this point).

before announcement info is only going to be available to resellers and companies with a non disclosure agreement (or planning to spend lots of money of course).

Watching how fast IOS has grown in bloat in the last couple of years (ie. confortably sitting in 32M of RAM for the small to mid CPE size routers to requiring 256M now for some platforms and the full feature sets), its going to be a gamble of what Cisco does. And if modular IOS ever comes out.

Probably not.

I don't think there is any general document you'll find. Typically Cisco will let a couple revisions of hardware out before they'll do EOL on the previous ones. So you probably have some time to go. Just look at how resilient the 3640s still are out in the world.

At this point in time, I don't think you'd need the newest and latest unless you wanted to start living more on the edge. Sometimes its nice if you do want to do some of the fast growth (ie. VOIP) options to have the latest gear. But you also tend to pay more for the newest/biggest/latest kit too.
