Research a service discovery protocol and describe how it is

Solution

There are number of service protocols available as like mentioned below :

Describing about DHCP - how it is used and the requirements for it to be adopted

DHCP is used for automatic configuration of client network interface. When configuring the client system, the administrator chooses DHCP instead of always specifying an IP address, netmask, gateway, or DNS servers. The client takes or retrieves the information from the DHCP server. DHCP is also useful if an administrator wants to change the IP addresses of a large number of systems. Instead of configuring again all the systems, he can just edit one DHCP configuration file on the server for the new set of IP addresses which he want to configure .If the DNS servers for an organization changes in worst case scenarion , the changes are made on the DHCP server, not on the DHCP clients. When the administrator restarts the network or reboots all the clients, the changes will go into effect.

If an organization has a DHCP server properly connected in a network, laptop and other mobile computer users can move these devices from one work place to other workplace.

Meta information about a service that is included in the service listing.

Openstack has now given an option to enable metadata proxy service in DHCP service name space, thus metadata service can work in isolated network, no need to attach network to any neutron router.

Just we need to configure /etc/neutron/dhcp_agent.ini for enabling this.

After configuring just Restart neutron-dhcp-agent on every controller node.
