Ever since connecting to a Chromecast, my device floods the network with SSDP packets I used both a Galaxy Nexus and a Nexus 7, running stock Android 4.3 and 4.4, to interact with a Chromecast in the past. Ever since, both devices flood the network with SSDP packets, which seems to be a UPnP related service discovery protocol. "Flood" here means that new packets are sent every second. 

A sample packet, decoded by using WireShark, is shown below:

Internet Protocol Version 4, Src: android-28f8778edbb436c2.lan (192.168.200.120), Dst: 239.255.255.250 (239.255.255.250)

As this creates unneccessary traffic and likely drains the battery, I would like to deactivate this discovery feature. But even uninstalling the Chromecast app, Chrome itself, the Youtube app and other likely related apps (essentially everything that interacted with the Chromecast) did not help, the device still sends those packets.

Does anyone know how to disable this device discovery feature?
I doubt there is a setting on the Phone or on the Chromecast device that allows you to set the SSDP query interval. I've certainly never seen one.

Technical detail
Firstly, 1 UDP packet a second is not a flood.  Secondly, it's just the device sending out SSDP probes.  This is not a big deal.  I think once a second might be a bit much for a discovery protocol - once every 5 seconds for the application might be better, but that's just quibbling over a few seconds.  If the device was &quot;flooding&quot; the network with a thousand or more a second, then you'd have a problem.
WS-Discovery (which is a similar discovery protocol) uses the same multicast group (239.255.255.250) but on a different port (3702).  Make sure you aren't mixing up SSDP with WS-Discovery probes and responses.  If you have Windows boxes on your network, you'll see a lot of (WS-Discovery) messages bouncing around.
Also, in your typical network with Apple devices or AirPrint printers, you'll see a lot of Apple Bonjour (mDNS service discovery) UDP packets flying around on 224.0.0.251.  If you get less than 1 UPD message per second at this address, then you have a really quiet network (or some really old devices).
There is likely a bunch of other UDP multicast packets flying about on your network as well.
So, any modern local network with a modicum of devices will have at least 3 service discovery protocols chatting away at any given time - WS-Discovery, SSDP and mDNS.  If you have databases or other routers, then you'll have a couple more multicast service discovery protocols firing away.  The amount of traffic created by these protocols in the way they are implemented by most devices is just some minor network overhead.  Don't worry about it.
