Investigation of Dynamic Network Management in an OpenFlow Enabled Network
Type: |
Cisco
Request for Proposal (RFP) Grant |
Amount: |
$(US) 78,000 |
Status: |
Current (Due to conclude in December 2016) |
Abstract: |
The Centre for Advanced Internet Architectures (CAIA) at Swinburne University
has previously worked on techniques for real-time classification of Internet traffic
and the subsequent use of this information to shape traffic in the network. OpenFlow
based switches offer the opportunity to segregate the Control and Forwarding Planes
of networking infrastructure, allowing for innovative techniques for dynamic network
management. We see an opportunity to combine our work on traffic classification with
the networking paradigm afforded by OpenFlow technology to develop automated network
management systems that can dynamically respond to real-time traffic flow characteristics.
In this project we propose a project with two coupled themes, 1) To explore the potential
for using the OpenFlow protocol to gather statistical data that can then be used to perform
classification of traffic; and 2) To extend the our existing DIFFUSE traffic classification/management
infrastructure to support dynamic instantiation of traffic management rules on an OpenFlow-enabled
switch. The outcome of this projects will include a set of proposed extensions/modifications
to the existing OpenFlow protocols to better support real-time statistical based traffic
classification, and an Open Source release supporting an extension to the existing DIFFUSE
architecture to support dynamic network reconfiguration on an OpenFlow based network.

Test-bed for Wide-Area Software Defined Networking Research
Type: |
ARC LIEF Grant |
Amount: |
$270,000 |
Status: |
Current |
Abstract: |
This project aims to develop a wide-area test-bed spanning ten organisations for conducting
research and experimentation in the emerging disruptive technology of software defined
networking (SDN). SDN is going to bring long-term transformation to the networking industry,
much like cloud computing did, by enabling dynamic virtualised elastic network services under
software control. The test-bed will empower Australian researchers in network technologies and
dependent applications (e.g. multimedia and security) to collaboratively develop and demonstrate
novel ideas at scale. This will benefit Australia by giving our researchers international
recognition in this nascent area, and developing a national talent pool for local industry.

FreeBSD implementation of an SCTP friendly NAT
Type: |
Cisco
Request for Proposal (RFP) Grant |
Amount: |
$(US) 78,000 |
Status: |
Completed December 2008 |
Abstract: |
Network Address Translation (NAT) is typically used to share a single Internet
address amongst a number of users. Extending the common approach used in NAT
implementations for TCP and UDP to the SCTP protocol is not viable - the SCTP
protocol specification would require checksums for the whole packet (not just
the header) to be re-calculated for each packet - particularly for small home
router implementations. Further, SCTP also offers multi-homing which offers new
challenges for the NAT code to track in a single SCTP connection. We propose to
develop a NAT implementation to support SCTP to be released for the FreeBSD 6.2
(or its replacement as of August 2007) platform. Our release code will utilise
an existing NAT framework such as ipfw or ipf such that it can be practically
deployed on real systems. The NAT will track SCTP connections via the Verification
Tag (VTag) field and retain connection details should one end of a multi-homed
session change end-points. We also propose to test this implementation under a
number of different usage and failure-mode scenarios, the results of these tests
will be published and can be used to promote the use of SCTP "in-the-wild". |
Analysis of BitTorrent Performance in a Content Caching Context
Type: |
Swinburne
Researcher Development Scheme |
Amount: |
$27,491 |
Status: |
Competed September 2007 |
Abstract: |
The ICE3 project at CAIA attempts to characterise the performance and service
quality impact of inverting the network content and capacity hierarchy, in
particular with regard to existing networked applications. One of the conjectures
is that this increase in edge bandwidth will not necessarily improve perceived
Internet performance without the location of local content caches around the
edge of the network. This may be true for traditional caching schemes but the
recent popularity of new protocols like BitTorrent have turned content
distribution (particularly for large downloads) on its head, pushing the load
of delivering content onto users participating on downloading that content
rather than just on the content supplier.
This project will seek to analyse the performance of BitTorrent in the current
network architecture and to develop model to accurately predict its performance
in an inverted hierarchy network. It is expected that this will allow us to
accurately compare the performance of BitTorrent against that of traditional
caching schemes in the realm of content delivery. |
