Help Norton Premier Edition,Constantly In My Security History,Rule "Default Block SSDP Blocked"

Every-time I check my Norton premier edition security history I see ... rule 'default block ssdp' blocked (www.routerlogin.com (my router ip), port 2869) Inbound TCP Connection Local address service is (my computer), port 2869) Remote address service is ( www.routerlogin.com (my router ip), port 3199) Multiple times a minute. I have never seen this message in my history before I upgraded my version of Norton, yesterday, I want to know if that message is something I should be concerned about and why it's showing up so much in my history?
