Router manufacturers such as TP-Link, Linksys and Netgear have acknowledged the problem and issued firmware updates, and these updates will act as mitigation until a patch for Cast is issued by Google itself.Ī company spokesperson told 9to5Google that its team is “working quickly to share a solution”. If this issue isn’t remedied, the router’s memory could be filled up completely by the MDNS packets, leaving users with no choice but to reboot in order to restore the internet connection. UDP has no congestion control features, so a device sending multiple UDP packets in a short burst can grind things to a standstill pretty swiftly. MDNS uses User Datagram Protocol (UDG) to send information packets. This happens when the Google device is awoken from its ‘sleep’ state and, the longer it is in sleep mode, the larger the quantity of MDNS packets sent will be once it ‘wakes up’. The problem seems to be that the Google devices will broadcast a large amount of these packets at rapid speed in a short space of time. According to XDA-Developers, packets are usually sent every 20 seconds or so. MDNS resolves the hostnames or assigned network names of devices to IP addresses, and is widely used on local networks without a DNS server. TP-Link engineers explained that the Cast feature sends multicast DNS (MDNS) packets to discover and keep a live connection with Google products. The issue was first brought up on Google Product Forums in relation to the TP-Link Archer 1200 router, according to The Register. The bug itself is not a router problem, rather an issue with the ‘Cast’ feature itself.
