5 Questions
What is the purpose of service discovery in an IoT ecosystem?
The purpose of service discovery in an IoT ecosystem is for IoT devices to advertise and use the services of other devices in the network.
What is the purpose of DNS service discovery (DNS-SD)?
The purpose of DNS service discovery (DNS-SD) is to enable IoT devices to discover and utilize services available in the network using DNS-based mechanisms.
Name three prominent service discovery protocols used for IoT devices.
The three prominent service discovery protocols used for IoT devices are DNS service discovery (DNS-SD), Multicast domain name system (mDNS), and Simple service discovery protocol (part of UPnP).
What is mDNS used for in an IoT ecosystem?
mDNS (Multicast domain name system) is used for service discovery in local networks without the need for a centralized DNS server. It allows devices to discover and communicate with each other using multicast DNS messages.
Why is a layered architecture important for IoT?
A layered architecture is important for IoT to enable seamless connection and data transfer among billions and trillions of devices. It allows scalability and flexibility to accommodate the various components and technologies in the IoT ecosystem.
