i am not familar with the FPGA board. but my point was that the stability of kernel (freebsd) is different from that of routing software (rpd in the case of junos, it has modules like is-is, ospf, bgp, mpls, rsvp, etc). people who architected the junos are the same group of people who coded original cisco ios. they had learned the heavy lessons from the past experience and craft rfcs ... asic and FPGA are more concerned with packet forwarding/performance, buffer management and so forth, not the stability of routing daemons. --- Aaron Gibson <agibson@confabulator.net> wrote: > gahn wrote: > > juniper just uses hardened freebsd kernel for its > os > > to run all of other processes such as routing, > snmp, > > monitoring the chansises.. etc. those individula > > processes/daemons are totally writen by juniper > gurus > > and has nothing to do with freebsd development. > that > > is why the routing engine uses intel cpu, which > has > > volume sale and easy to be upgraded. > > > > what makes juniper routers prefered choice for > telecom > > is its stablity. cisco line cards can boast the > > similar performance like juniper asic based packet > > processing/forwarding engine. in fact, every > vendor > > uses asic for their product (performance). but > cisco > > old ios just can't provide the stablity that of > junos. > > ios-xr might be since it is totally rewriten. > > > > just use freebsd for routing platefom wont give > you > > anything near the stablity that juniper routers > > provide; unles you are genius and writing your own > > routing software on the top of freebsd kernel. > > > > > > --- Aaron Gibson <agibson@confabulator.net> wrote: > > > >> root@rithy4u.net wrote: > >>> Dear All, > >>> > >>> Can we use FreeBSD in Telecom industry?
