All Implemented Interfaces:

Protocol

public class RTPProtocol

extends Object

implements Protocol

RTPProtocol is a partial implementation of the RTP protocol. It is an invocation protocol allowing the emission of one-way requests packaged within RTP packets. Requests whose size exceeds the mtu of the underlying transport are fragmented and reassembled. The semantics of this protocol depends on the specific transport protocol on top of which it is plugged. RTPProtocol, proper, is unreliable and unordered

Field Summary

static int	rtp_version the version of RTP supported

Constructor Summary

RTPProtocol(int mtu)

Method Summary

boolean	isAnInvocationProtocol() Returns true if the target protocol is an invocation protocol.
ProtocolGraph	newProtocolGraph(ProtocolGraph next) Builds a new RTP ProtocolGraph

Constructor Detail

RTPProtocol

public RTPProtocol(int mtu)

Builds a new RTPProtocol instance

Parameters:

mtu - the mtu that the RTPProtocol will assume for fragmenting messages

Method Detail

isAnInvocationProtocol

public boolean isAnInvocationProtocol()

Description copied from interface: Protocol

Returns true if the target protocol is an invocation protocol.

An invocation protocol is a protocol able to handle invocations, i.e., requests expecting a reply. In practice, this means that calls to the prepareInvocation method on sessions obtained from the target protocol will not raise an InternalException, but perform the appropriate work.

Specified by:

isAnInvocationProtocol in interface Protocol

Following copied from interface: org.objectweb.jonathan.apis.protocols.Protocol

Returns:

true if the target protocol is an invocation protocol.

newSessionIdentifier

public SessionIdentifier newSessionIdentifier(SessionIdentifier next)

Builds a new RTP SessionIdentifier

Parameters:

next - the lower level session identifier

Returns:

a new RTP SessionIdentifier.

newProtocolGraph

public ProtocolGraph newProtocolGraph(ProtocolGraph next)

Builds a new RTP ProtocolGraph

Parameters:

next - the lower level protocol graph.

Returns:

a new protocol graph.
