1 ZERO CONFIGURATION NETWORKING PUSPARAJ MOHAPATRA SCHOOL OF INFORMATION TECHNOLOGY IIT KHARAGPUR

2 TOPICS TO BE COVERED Introduction Essential network services & configuration Managing IP host configuration Architectural issues of zeroconf Status of ongoing work Future implication Conclusion Reference

3 INTRODUCTION Today’s growing network infrastructure Demerits of today’s networking Zero configuration networking --A Boon to Network Infrastructure

4 IP CONFIGURATION PARAMETERS IP Address Subnet mask Default router address Domain name Domain name server

5 IP CONFIGURATION Static configuration Dynamic configuration Automatic configuration Figure:

6 DESTINATION ADDRESS DISCOVERY There are 3 ways IP address configuration(self) Domain name configuration(DNS) Service discovery(DHCP) Multicast Address Allocation:MADCAP

7 ARCHITECTURAL ISSUES IN ZEROCONF Zeroconf constraints are : Ease of use Scalability Automatic translation to & from configured networking Secure operation Transparency Independence

8 ONGOING WORK Requirement specification by IETF group Zeroconf protocol areas under consideration  Automatic host configuration  Service discovery  Multicast domain name to address resolution  Automatic multicast address allocation  Transition to secure operation

9 AUTOMATIC HOST CONFIGURATION IPV6 has address auto configuration Claim & defend protocol is insufficient Reclaim will be added Link-local address

10 CREATION OF LINK-LOCAL ADDRESS Link-local address: well known link-local prefix+interface identifier Interface identifier:Interface's link-layer address Link-local prefix:FE80::0

11 CREATION cont… Link-local address is created after the following events:  Interface is initialized at system startup time  Interface attaches to a link for the first time  Interface is reinitiated after a temporary interface failure  Interface becomes enabled by system management having been administratively disabled

12 MULTICAST DOMAIN NAME TO ADDRESS RESOLUTION *Multicast DNS(mdns) Claim and defend mechanism “stub” naming service in hosts Hosts assign themselves a domain name with “.local” suffix Multicast to broadcast address( ) Claim & defend mechanism applies Host can use caches.

13 SERVICE DISCOVERY Service allocation protocol(SLP)  Can use both in IPV 4 & IPV 6  SLP agent is deployed on each host  Multicast the message with type of service attributes  3 rd party can also cache this information

14 AUTOMATIC MULTICAST ADDRESS ALLOCATION Allows a host to obtain an address allocation for a multicast group for the host’s own purposes Still in development stage, but there is one protocol which will support this  Zeroconf Multicast allocation protocol (ZMAAP)

15 Working of ZMAAP Multicast Address Allocation Server (MAAS): A node providing multicast address allocation services to network clients. Mini-MAAS: A service providing multicast address allocation services to applications running on the same host. Mini-MAASs cooperate to provide network-wide services in small networks without MAASs.It is local to a host. Mini-MAAS contacts other Mini-MAAS for address allocation

16 Translation to secure operations Future work  Feasible inside the computers or in emergency shelters  Scale to internet  Owners & operations cannot know the presence of a network
