Syntax

public synchronized void send( DatagramPacket p, byte ttl ) throws IOException

Parameters

p: is the packet to be sent. The packet should contain the destination multicast ip address and the data to be sent. One does not need to be the member of the group to send packets to a destination multicast address.
ttl: optional time to live for multicast packet. default ttl is 1.

Description

Sends a datagram packet to the destination, with a TTL (time- to-live) other than the default for the socket. This method need only be used in instances where a particular TTL is desired; otherwise it is preferable to set a TTL once on the socket, and use that default TTL for all packets. This method does not alter the default TTL for the socket.

Exceptions

IOException is raised if an error occurs i.e error while setting ttl.
