Oct 1, 2010	The PSIRP project has officially ended. The work will continue in PURSUIT, which is also a FP7 EU project.
Jan 15, 2010	A new technical report is available on the Publications & Presentations page: Inter-domain Rendezvous Service Architecture
Jan 1, 2010	Happy New Year!
Nov 12, 2009	v0.2 of the Blackhawk prototype has been released. The source code and a virtual machine image with FreeBSD 7.2 (64 bit) are available here.
Sept 4, 2009	Two new scientific articles are available on the Publications & Presentations page: Illustrating a Publish-Subscribe Internet Architecture. LIPSIN: Line Speed Publish/Subscribe Inter-Networking
July 29, 2009	NetFPGA zFilter forwarding node version 1.1 is released. The source code is available here.
July 2, 2009	A virtual machine image with FreeBSD 7.2 (64-bit) and Blackhawk v0.1 can be downloaded from here.
June 25, 2009	Blackhawk Pub/Sub Prototype v0.1 released Version 0.1 of the Blackhawk prototype features a blackboard-based publish/subscribe system integrated with the FreeBSD kernel. Additionally, it offers the possibility to build small-scale pub/sub networks that utilize zFilter forwarding. The source code, published under the GPLv2 and BSD licenses, can be downloaded from here.
April 30, 2009	A new deliverable is now available on the Publications & Presentations page: First report on quantitative and qualitative architecture validation (D4.2).
April 17, 2009	Packet Level Authentication (PLA) library release Packet Level Authentication (PLA) is a novel method for protecting the network infrastructure by using per-packet cryptographic signatures. This release contains a standalone version of the PLA library, including a software implementation of cryptographic functions. It requires OpenSSL and GNU MP Bignum libraries and headers. The source code can be downloaded from here.
April 7, 2009	Prototype implementation of zFilter based forwarding node for a NetFPGA http://www.netfpga.org/ has been published. It is basically a switch that uses Bloom-filter-based packet headers, described for example in "LIPSIN: Line Speed Publish/Subscribe Inter- Networking" http://www.psirp.org/files/Deliverables/PSIRP-TR09-0001_LIPSIN.pdf, to make forwarding decisions. Publication includes project source code that can be used with freely available NetFPGA reference libraries to synthesize bit file for NetFPGA cards. The source code can be downloaded as from here.
March 10, 2009	PSIRP project had a technical review in Brussels.
Feburary 27, 2009	A new deliverable is now available on the Publications & Presentations page: Architecture Definition, Component Descriptions and Requirements (D2.3).
January 21, 2009	A Technical Report, "LIPSIN: Line Speed Publish/Subscribe Inter- Networking" was published. The report describes shortly the space where the pub/sub paradigm replaces send / receive completely, throughout the stack. In particular, we introduce a new eficient forwarding architecture that naturally supports multicast and may be relatively easily extended to support networking functions beyond forwarding, including network coding and caching. The novelty of our approach consists of compacting source route link identifiers in small Bloom-filter-based packet headers.
November 21, 2008	A conference paper Peer Assisted Content Distribution over Router Assisted Overlay Multicast was presented in Euro-NF Future Internet Architecture Workshop, November 20-21. Even assuming that multicast will become prevalent in a future publish/subscribe Internet, the peer assisted content distribution provided by applications such as BitTorrent will still be useful for asynchronously distributing very large amounts of data. We have designed a multicast variant of BitTorrent, paying special attention to the incentives required to ensure that peers will not only consume, but also contribute content, in a multicast setting. To provide a multicast substrate for our application we also present an overlay multicast scheme inspired by Scribe that exploits co-operative access routers to improve the multicast distribution trees.
September 8, 2008	The first major deliverable Conceptual Architecture of PSIRP: including sub-components descriptions (D2.2) has been published. D2.2 provides the first results of the project's architectural effort. It outlines the project's vision, its overall design methodology as well as the goals of the design effort. It then presents the major conceptual developments that are driven forward in later deliverables, namely the concepts of naming data and meta-data on different levels, enabling the construction of information networks (scoping) and the general publish-subscribe communication model used within these networks. This leads to a first conceptual architecture being presented together with its main components. The deliverable also outlines first ideas on design choices currently worked on. Finally, considerations are outlined as to how specific application types could be implemented in a PSIRP architecture.
August 18, 2008	New deliverables published on the Publications & Presentations page: State of the art Report and Technical Requirements (D2.1), Preliminary Validation Plan and Selection of Tools (D4.1), and Dissemination and exploitation plan (D5.2).
June 30, 2008	The PSIRP Vision Document is now available for download. It and other completed public deliverables and reports can be found on the Publications & Presentations page.
