Setting 'Throughput' gives a TOS hex value of 0x8 (equivalent to.

Setting 'Reliability' gives a TOS hex value of 0x4 (equivalent to DSCP decimal value of 1).

However, there are some serious bugs in the QoS settings available: I blogged about setting DSCP values for Crashplan traffic on a Synology NAS, but in short you can set the TOS or DSCP value of upload traffic using the Crashplan GUI. I appreciate any insight or suggestion on this, maybe using the NAS? I have other network devices but I guess those don't matter for this specific issue, like a Wireless Extender acting as AP and another switch in another room.

Synology DS412+ NAS that also is acting as a local DNS Server (both routers are forwarding DNS requests to this server)ĬrashPlan is installed on the Synology NAS and has specific QoS settings:Īdvanced users only: must have QoS capable router configured.Ĭhoose the TCP Packet quality or custom DSCP value from the list: Low, Normal, Reliability, Throughput or DSCP….

Netgear WNDR3700 v2 router with DD-WRT acting basically as a switch for Gigabit LAN (the technicolor only has one Gigabit port), with DHCP forwarding to the main router.

Technicolor home router acting as DHCP Server, which cannot be replaced because it is also handling IPTV and landline telephone (this router is actually connected to another router, both from my internet provider, that translates the fiber optics broadband connection).

What happens is that when CrashPlan is uploading files it occupies a huge part of the available bandwitdh, reducing overal internet access speeds for uploading or downloading. Still, I would like to implement QoS, mainly to be able to control bandwidth occupancy by CrashPlan while it's backing up files. My home router (Technicolor TG784n v3, firmware version 8.G.M.1) has no Quality of Service (QoS) settings.
