When possible, administrators use the ip helper-address command to relay broadcast requests for these key User Datagram Protocol (UDP) services. By using the ip helper-address command, a router can be configured to accept a broadcast request for a UDP service and then forward it as a unicast to a specific IP address, as shown in Figure 2-21.

Both UDP and TCP run on top of IP and are sometimes referred to as UDP/IP or TCP/IP; however, there are important differences between the two. For example, UDP enables process-to-process communication, while TCP supports host-to-host communication. Furthermore, TCP sends individual packets and is considered a reliable transport medium. In UDP, the client does not form a connection with the server like in TCP and instead just sends a datagram. Similarly, the server need not accept a connection and just waits for datagrams to arrive. Datagrams upon arrival contain the address of sender which the server uses to send data to the correct client. Feb 24, 2019 · UDP forwarding rewrites the broadcast IP address of a UDP packet to either a unicast (specific host) IP address or a directed IP broadcast. After the address is rewritten the UDP packet is forwarded by all of the routers in the path to the destination network without requiring additional configuration changes on the other routers. As a service to network providers, Nasdaq maintains a consolidated list of IP addresses for its UDP/IP services. Please note that Nasdaq reserves the right to modify this IP address information as needed for network and operational reasons.
