udp/session: refactor to support dgram mode
- adds session layer support for datagram based protocols - updates udp to work in pure connectionless and datagram mode. The existing connected mode is now 'accessible' for apps as a dummy UDPC, as in, connected udp, protocol. - updates udp_echo, echo client, echo server code to work in datagram mode.

Vector Packet Processing
========================

## Introduction

The VPP platform is an extensible framework that provides out-of-the-box
production quality switch/router functionality. It is the open source version
of Cisco's Vector Packet Processing (VPP) technology: a high performance,
packet-processing stack that can run on commodity CPUs.

The benefits of this implementation of VPP are its high performance, proven
technology, its modularity and flexibility, and rich feature set.

For more information on VPP and its features please visit the
[FD.io website](http://fd.io/) and
[What is VPP?](https://wiki.fd.io/view/VPP/What_is_VPP%3F) pages.


## Changes

Details of the changes leading up to this version of VPP can be found under

## Getting started

In general anyone interested in building, developing or running VPP should
consult the [VPP wiki](https://wiki.fd.io/view/VPP) for more complete
documentation.

In particular, readers are recommended to take a look at [Pulling, Building,
Running, Hacking, Pushing](https://wiki.fd.io/view/VPP/Pulling,_Building,_Run
ning,_Hacking_and_Pushing_VPP_Code) which provides extensive step-by-step
coverage of the topic.

For the impatient, some salient information is distilled below.


### Quick-start: On an existing Linux host

To install system dependencies, build VPP and then install it, simply run the
build script. This should be performed a non-privileged user with `sudo`
access from the project base directory:

    ./extras/vagrant/build.sh

If you want a more fine-grained approach because you intend to do some
development work, the `Makefile` in the root directory of the source tree
provides several convenience shortcuts as `make` targets that may be of
interest. To see the available targets run:

    make


### Quick-start: Vagrant

The directory `extras/vagrant` contains a `VagrantFile` and supporting
scripts to bootstrap a working VPP inside a Vagrant-managed Virtual Machine.
This VM can then be used to test concepts with VPP or as a development
platform to extend VPP. Some obvious caveats apply when using a VM for VPP
since its performance will never match that of bare metal; if your work is
timing or performance sensitive, consider using bare metal in addition or
instead of the VM.

For this to work you will need a working installation of Vagrant. Instructions
for this can be found [on the Setting up Vagrant wiki page]
(https://wiki.fd.io/view/DEV/Setting_Up_Vagrant).


## More information

Several modules provide documentation, see @subpage user_doc for more
end-user-oriented information. Also see @subpage dev_doc for developer notes.

Visit the [VPP wiki](https://wiki.fd.io/view/VPP) for details on more
advanced building strategies and other development notes.


## Test Framework

There is PyDoc generated documentation available for the VPP test framework.
See @ref test_framework_doc for details.
