Control and Management Protocols

• Not all control and management protocols are suitable for UDP

• Those that are have the following characteristics

• • Low traffic
  • • No need for explicit connection setup overhead
  • Small packets
  • • Typically much less than an Ethernet MTU
  • Simple request-response design
  • • Application retransmit strategy easier to implement
  • Iterative servers
  • • One client request at a time

• Some of these protocols build in their own reliability at the application layer

• Examples

• • DHCP, DNS, SNMP, RIP, etc.
