Gigabit Broadband Support

My city is currently investing in fiber to the home--soon I'll have a full gigabit connection at my house!  :)  I realize that there is a WAN gigabit Ethernet port and wireless speeds are claimed to be up to 2.4Gbps, but wanted to make sure the Core could handle a full gigabit Internet connection.  My understanding is that some routers (especially in deep packet inspection is involved) are unable to achieve a full gigabit. Thanks!

Re: Gigabit Broadband Support

From the Core FAQS

Wireless connectivity

  • Simultaneous dual-band 2.4-GHz & 5-GHz WiFi radios

  • AC2600 (800 Mbps @ 2.4-GHz + 1733 Mbps @ 5GHz)

  • 4x4 MU-MIMO, IEEE 802.11a/b/g/n/ac Wave 2

  • Bluetooth Low Energy (BLE)

Security and networking

  • DPI, IDS, IPS, WPA2, DHCP, NAT, UPnP

  • Automatic device discovery

Wired connectivity

  • 1 x Gigabit WAN port (cable or DSL modem)

  • 3 x Gigabit LAN ports (networked devices)

If a router is using deep packet inspection, you will lose a % of the speed offered by your isp. But if you are starting at 1 Gbps, your eventual speed still be greater than if you did not have a Gbps connection. There is always going to be some performance hit when more work is being done with your data.

So will you actually see 1 Gbps, probably not. But you will still see a lot more than someone using, say, a 120Mbps connection.

Re: Gigabit Broadband Support

Thanks for your response.  Do we have any sense at all for the amount of performance reduction?

As an example, see https://www.smallnetbuilder.com/lanwan/lanwan-reviews/33108-cujo-smart-internet-firewall-second-look 

When CUJO was first released, it couldn't achieve more than 425M even though it had gigabit ports.  After updates, it was rated to reach 750M, and real-world tests show it closer to 667M (so pretty close).  

For me, I'd be pretty disappointed in the core only delivered 425M on a Gigabit connection, and likely alright with the trade-off if it was closer to 667M.  

Thoughts?

Re: Gigabit Broadband Support

As the device is only available to Norton Employees at this time, no one here can give you any information on the speed reductions.

Re: Gigabit Broadband Support

One other thing to remember when comparing the CUJO device to the Core, The Core is a full router with parental controls, User accounts, and the firewall capabilities. CUJO is just a smart firewall appliance. So you still need to buy or use a router to fully protect your network.

But the Core has a 1.7 GHz dual core processor, vs the CUJO's 1.2 GHz dual core processor. 

So we will have to wait and see.

Re: Gigabit Broadband Support

Just wanted to share this link to an Amazon review with some thoughtful observations.  It appears that 70-80Mbps was the most the poster could sustain through the Core unless the security settings were disabled.

Is anyone else experiencing better performance?  Or finding specific sites that are "trusted" and perform better with analysis on?

Re: Gigabit Broadband Support

Also, in addition to what peterweb has mentioned, at this point we are still analyzing the impact, but most traffic does not need to be inspected by DPI for an average user, so this really should not be an issue for most sites. Encrypted/trusted sites should not be impacted. The debate revolves around speed vs. security, however, lowering security to increase speed is not recommended. Thanks.

Re: Gigabit Broadband Support

So all a malware site has to do to bypass DPI is buy an SSL cert (available just about anywhere) and use https?

Re: Gigabit Broadband Support

And that is why the Norton Core Security Plus software subscription is included with the Core. The software will catch anything that might come through from an https site. As the Norton Security products do now.

The Core might be able to be designed to have DPI check encrypted data, but how much more drag on performance would be added by the decryption before inspection. The web would become almost unusable.

Re: Gigabit Broadband Support

I am seeing a cap at 80mps.. I get about 350 on my cell and with the core and packet inspection on 68 to 75... turn off packet inspection and I'm back up to 350ish plus.  Security at a price i guess...

My point is, if this can't be done by the router (with reasonable performance) and even then is still incomplete (SSL), why do it in the router at all? Why not client side where you (should) have ample resources and access to the SSL session key or the data before / after encryption.

I guess my question turns into "Why the whole router"?

Re: Gigabit Broadband Support

I'm getting Slower internet speed with Network inspection on my ISP Speed is 105 Mbps  Latency 6 ms  Upload 8.93 Mbps and when I turn on Network inspection Default it drops 59 Mbps down Latency 18 ms Upload is about the same just wanted to report this
