I am doing some training in examining PCAP files for attacks. I am particularly suspicious of an SSDP protocol NOTIFY HTTP/1.1 which over a 10 minute period has appeared 1710 times from the same local IP address. Could this be seen as a denial of service attack?

SSDP is the Simple Service Discovery Protocol, which is really chatty. If it shows up it means that a node is trying to discover services, e.g. printers, shared folders, iTunes Libraries, etc. I doubt that you're seeing a DoS attack, because it's not flooding enough packets for that. DoS attacks have thousands of packets per second, not minutes ;-)
