i have cisco 3845 with 1 GB SFP, my company using fiber as backbone to isp, i have new internet connection 310 Mbps, does that enough ?

With CEF enabled, the 3845 can push up to 256 Mbps of HALF DUPLEX and UN-ENCRYPTED traffic.

So it's not enough.

If you want to push 310 Mbps full duplex traffic then you'd be looking at a 7200 with NPE G2.

You can also use the 3945E for this purpose

I doubt a 3945E will suffice.

The 3945E is rated at 502.78 Mbps and this value is expressed in HALF DUPLEX.

In table 1 of the attachment, that's the rating for the non-E version, i.e. 982 Kpps (502.78 Mbps).

The E version is rated at 2,924 Kpps, compared to the G2's 2,000 Kpps.

In that case, my apologies to "claudm".

Depends on how "busy" your expect the link to be and what services you plan to configure.  In general, a 3845 is unable to fully drive 310 Mbps.

For 310 Mbps, you might get by with a 2951, but you'll likely do better with a 39xx or 72xx/73xx with a G1/G2/NSE.

If it's likely you might further increase your bandwidth, look to the high side of the 39xx or 72xx/73xx series, or look at a ASR 1xxx.

You can use if for any purpose.  The SFP, though, allows a fiber Ethernet connection.
