Class MulticastMaxPacketSize

java.lang.Object

org.apache.river.discovery.MulticastMaxPacketSize

All Implemented Interfaces:

Serializable, InvocationConstraint

public final class MulticastMaxPacketSize
extends Object
implements InvocationConstraint, Serializable

Represents a constraint on the size (in bytes) of multicast packets used in the multicast request and multicast announcement discovery protocols. Lookup services and discovery clients can use this constraint to limit the size of multicast request and announcement packets sent, so as to avoid fragmentation or loss when the packets traverse routers. This constraint can also be used to control the size of the buffers used to receive incoming multicast request and announcement packets.
