Greg has laid out a great bit of information and I would like to add just one possibility to the list of budget 10GE routers: Vyatta. According to a recent press release from that company ( they offer a product that is "2 to 3X higher performance at a cost savings of more than 75 percent" when compared to Cisco's 7200. Unfortunately I have not had the opportunity to test or use the Vyatta routers yet; I have however successfully used other open-source Linux based routers in the past with great success. If you are looking for a truly budget 10GE router, they may be worth adding to the list and looking into.

Whether you can actually do 10Gb/s reasonably on a linux or freebsd soft-switched router platform is going to depend a lot on your actual pps rate.

800K pps which is 10Gb/s / 1500 bytes is feasible, but 19M pps which is 10Gb/s / 64 bytes is not.

Susceptibility to dos traffic at relatively low bit, but high pps rates is a general issue with soft-switched platforms. and needs to be accounted for in model deployments.

    When it comes to budget, force10 are good. I wouldn't be able to
    confirm if they're worth performance-wise.
    I'd strongly suggest Foundry, I'm a big fan of their kits, price-wise
    and performance-wise, provided you do not need rocket-science features.
    MLX/XMR models will surely do the trick perfectly.

    When it comes to router purchasing habits, we all tend to get
    Bottom line is that most of the 'regular' vendors (namely Cisco,
    Juniper, Foundry, Force10, Extreme, Riverstone) implement pretty much
    the same set of features, which are all IETF/IEEE normalized, meaning
    if you don't need proprietary features (and you'll wish you don't),
    any router will be fine, the only difference will come from:
    - the chassis being non-blocking or not (i.e. backplane design)
    - the price per port
    - the operating OS
    - the feeling you'll get with the salesperson, and the reputation of
    their Support Teams.
    - vendor specific features such as Flow Sampling
    To make it simple, most vendors have an IOS like OS, except Juniper
    which has a really clever and elegant OS, but are very pricey.
    Foundry and Force10 have the cheapest price per port
    Cisco does only Netflow, Foundry & Force10 only SFlow (which is a true
    standard) and I think Juniper does JFlow
    Cisco's kits are packed with proprietary protocols (HSRP and GLBP
    instead of VRRP, their own ethernet trunking, EIGRP as their own and
    yet extremely efficient IGP, TCL scriptable CLI...) , some of them are
    really good, some are crappy, but I suggest you'd stick with IEEE/IETF
    protocol to avoid future trouble.

    One thing: RSTP/802-1w is very (very, very, very) not often
    interoperable between vendors who all have their own interpretation of
    the norm and can quickly turn into a nightmare.
    I'd strongly suggest try&buys if (R)STP interoperability is required,
    but I'm a little paranoid :)
