By:

Peter Griffin <peter.griffin@gd-ais.com>
updates covering waf build system by Duc Nguyen <dnguyen@aypeks.com>
Updated: 2018-03-14
The Java JNI bindings for NORM provide Java bindings for the NORM C API.
For documentation about the main NORM API calls, refer to the NORM Developers
guide in the regular NORM distribution.
The JNI bindings for NORM can be built using two methods. The original
method uses Make and an Ant build.xml script in makefiles/java. The
newer method uses the waf build system and builds for all platforms with
various configurations via configuration switches.
------------
Requirements
------------
Java JNI bindings for NORM requires at least Java 1.5; however, it has also
been tested with Java 1.6.
been tested with Java 1.6 and Java 1.8
The NORM library should be built prior to building the Java JNI bindings since
they link against it.
### Using Ant and Make ###
Apache Ant is required for building the class files and jar file.
### Python waf ###
Tested with Python 2 but Python 3 should be ok.
------------
Building
------------
### Using Ant and Make ###
The build files for Java JNI bindings for NORM are located in the
makefiles/java directory.

This will produce a libmil_navy_nrl_norm.so file in the lib/ directory.
### Python waf ###
Reconfigure waf to use java and choose the target on a windows system:
> cd <norm root dir>
> waf configure --build-java --msvc_target=x64
The msvc_target flag allows you to choose the target Windows
architecture. The default is "x86" (i.e. 32bit arch)
Build the NORM libraries:
> waf build
The output will be in the build/ directory. Copy both
mil_navy_nrl_norm.* and norm-1.* to the location the JRE libraries.

Installation
------------
@ -75,9 +106,23 @@ If you observe an "java.lang.UnsatisfiedLinkError" exception while running
your application, you do not have the libmil_navy_nrl_norm.so installed in
the correct location.
If you're running on Windows, you also need to have the PATH environment
variable set with along with the -Djava.library.path=<dir>
------------
Examples
------------
Examples using the Java JNI bindings for NORM are provided in the examples/java
directory.
Running on Windows (could be put in a .bat script):
set PATH=%PATH%;<path to mil_navy_nrl_norm.dll>
java -Djava.library.path=<path to mil_navy_nrl_norm.dll> ...
Running on Linux or MacOS:

NORM Version History
Version 1.5.7
=============
- Fixed issue with NormSession::SenderRemoveAckingNode() method where
the removed NormAckingNode instance was not being properly deleted.
(Thanks to Chad Gioia)
- Fixed bug in normPrecoder (npc) when building on 64-bit architectures
(Thanks to Leon Meyer)
- Fixed bug in JNI NormNode.getAddress() method where an "unsigned short"
type was used instead of "UINT16" to receive the port portion of the
address. (Thanks to Jame Nguyen)
- Reduced warnings, added gnu and other build options to 'waf' wscripts
(Thanks to Luca Buccassi)
- Greatly improved high speed performance via enhancements to Protolib
- Fixed bugs related to coding block id wrapping for very long-lived
(or very high speed) NORM sessions.
- Added NormSocket API extension in "norm/examples" that provides a
sockets-like API and client-server connection-oriented paradigm
for using NORM. This currently supports a byte-stream service
for both multicast and unicast using NORM_OBJECT_STREAM. This API
extension is still work in progress and will be expanded to include
message-stream service support as well as NORM's file/data object
modes. The "norm/examples/normClient.cpp" (and "normServer.cpp)
illustrates use of the the API extension defined in
"norm/examples/normSocket.h"
- Added "normStreamer" example that provides the same function as the
"normMsgr" example except using NORM_OBJECT_STREAM.
- The bug fixes and performance enhancements make this a key update.
The NORM Developer's Guide is not yet updated to described some of
the new API features added.
- Added APIs to iterate through sender "Acking Node List" to determine
who has and who has not acknowledged a watermark acknowledgement
request.
- Added NormSetAutoAckingNodes() call with NormTrackingStatus to
automate detection of new group members. The Acking Node List
iterator function NormGetNextAckingNode() can be used to learn
who has joined and the NORM_ACKING_NODE_NEW provides notification
to the application of new members.
- The 'waf' build scripts assign the current version number to
the NORM shared library built for better version control/tracking.
Version 1.5r6
=============
- Fixed Protolib ProtoBitmask bug for NDEBUG (release) builds.

NormSocket API Extension Notes
The NormSocket API (currently defined in examples/normSocket.h) is an in-development extension to the
base (low-level) NORM API (defined in include/normApi.h) that provides a more familiar (socket-like),
easier-to-use API for some specific NORM use patterns. The use patterns supported here are those of a
client-server paradigm where "clients" have individual, reliable connections to the server and the
"server" can have either a one-to-many multicast connection or individual unicast connections to the set
of clients. The paradigm follows a connection-oriented socket model where the server "listens" for
incoming connections initiated by clients. The low-level NORM API is used to establish multiple NORM
sessions as needed to support the necessary data exhange relationships. Since this is a
connection-oriented model, explicit ACK-based flow control used for both client-to-server and
server-to-client(s) data transfers. This is a more controlled model of NORM use as compared to the
looser "connection-free" model of operation NORM use has typically observed.
The NormSocket API code makes careful use of operating system socket-binding to enable port reuse and
simpler session establishment where clients can "connect" to the server listening on a well-known port
as compared to typical base NORM API use where participants can exchange data on a a priori known common
port number (and group address if multicast). However, the clients do need to know the unicast address
of the server and the paradigm is somewhat that of Single-Source Multicast (SSM). Client application
can, of course, using multiple NormSocket instances connect to multiple multicast (or unicast) servers..
THere
A server application can use the NormListen() call to establish a session that listens for incoming
connection requests, Client applications can use the NormConnect() call to initiate a connection to a
listening server. In response, the server application can use NormAccept() to establish connections with
the clients.
At the moment a NormGetSocketEvent() (analogous to the NormGetNextEvent() call in the base NORM API) can
be used to provide cues to changes in NormSocket state (notification of incoming connections, connection
establishment, read/write readiness, etc.). A descriptor is provided for asynchronous I/O notification
of pending events. At the moment, the default behavior is a single NormInstance, and hence a single
descriptor, can be used for multiple NormSockets, but it is possible to call NormCreateInstance() and
associate a separate NormInstance (and hence separate descriptor) with each NormSocket that is
listending, connected or accepted if desired.
As the NormSocket API extension matures, more examples and documentation will be provided as well as
incorporating it (possibly directly) into the "normApi.h" header file and NORM library. At the moment,
"examples/normClient.cpp" and "examples/normServer.cpp" illustrate (and test) basic usage of the API.
The "normServer" can be run as a unicast server using the syntax:
./normServer listen <serverPort>
or a multicast server using the syntax:
./normServer listen <groupAddr>/<serverPort>
Corresponding "normClient" instances can connect to unicast server using the syntax:
./normClient connect <serverAddr>/<serverPort>
or to a multicast server using the syntax:
./normClient connect <serverAddr>/<serverPort>,<groupAddr>
There are some additional command-line options shared by these examples such as "trace" to enable NORM's
message trace output and "debug <debugLevel>" to invoke different levels of debug output. Note that an
option to specify the multicast interface is planned but not yet implemented in these examples.
Similarly, an option to set a specific unicast server binding will also be provided.
TODO (not in priority order):
1) When client initiates connection and server-listener receives NORM_CMD(CC), add code
to directly "inject" the NORM_CMD(CC) into the newly created server-side client
session such that NORM_ACK is immediately sent. This will give client a more immediate
RTT measurement, etc.
2) Add options to set transmit rate, congestion control, etc options via NormSocketHandle
(current code works at default tx rate of 64 kbps)
3) The server-listener session should be modified so NORM_DATA messages are ignored. Also,
NormSetServerListener() could also set the session a silent receiver, too?
4) Add support for additional transport modes in addition to current byte stream:
` 1) Message stream
2) NORM_OBJECT_DATA (w/ data copy option?)
3) NORM_OBJECT_FILE
5) Add option to specify multicast "interface" and use in examples.
6) Enable setting a specific unicast server binding address.
===========================================================================
MISC. DEVELOPMENT NOTES
// Notional program outline
// (optional mcastAddr iff asymm multicast/unicast (i.e. SSM))
normSocket = NormListen(port, [mcastAddr])
_or_
normSocket = NormConnect(addr, port, [mcastAddr])
while NormGetSocketEvent(normSocket)
{
switch (event.GetType())
NORM_ACCEPT:
clientSocket = NormAccept(normSocket, client, [instance]); // rx-only for asymm mcast case
NORM_CONNECTED:
// in response to NormConnect when "server" is detected (NEW_REMOTE_SENDER)
NORM_TX_READY:
upon QUEUE_VACANCY, etc ... socket _might_ be write() ready
NORM_RX_READY:
upon RX_OBJECT_NEW, RX_OBJECT_UPDATE ... socket _might_ be read() ready
NORM_CLOSING: ???
upon stream end received from remote sender
NORM_CLOSED: ???
upon stream end _and_ ack to our stream end
}
*** Server listen on a port (optional mcast address):
- Create NormSession that receive-only on given port (if it's asymm mcast, then sender enabled, too)
- For each client (detected via NEW_REMOTE_SENDER yielding a NormSocket::NORM_ACCEPT event)
Create tightly binded session for rx (and tx if unicast) ... this will fail if binding already exists
*** Client connect
- Create single socket (common ephemeral tx/rx port) NormSession for server destination addr/port.
- Call NormStartSender() to initiate probing of server
- NORM_CONNECTED upon NEW_REMOTE_SENDER (from server) ???
QUESTIONS:
1) How does a server reject a connection request? (for now, just ignore)
2) How is a "connection" gracefully terminated? (NormShutdown() vs. NormClose()?)
NormClose(graceful = false) ...
a) stop sender/receiver, destroy everything
NormShutdown(graceful = true) ...
a) close stream (gracefully, w/ ack request)
b) upon ack receipt (or timeout) _and_ rx stream end, destroy everything
Upon receipt of rx stream end, close tx stream gracefully ...
initiator -> stream end; upon ack set tx_stream = NULL and wait for rx_stream end
receptor -> upon rx_stream end, initiate tx_stream shutdown and wait for ack
