On Ttethernet for Integrated Fault-Tolerant Spacecraft Networks
On TTEthernet for Integrated Fault-Tolerant Spacecraft Networks Andrew Loveless∗ NASA Johnson Space Center, Houston, TX, 77058 There has recently been a push for adopting integrated modular avionics (IMA) princi- ples in designing spacecraft architectures. This consolidation of multiple vehicle functions to shared computing platforms can significantly reduce spacecraft cost, weight, and de- sign complexity. Ethernet technology is attractive for inclusion in more integrated avionic systems due to its high speed, flexibility, and the availability of inexpensive commercial off-the-shelf (COTS) components. Furthermore, Ethernet can be augmented with a variety of quality of service (QoS) enhancements that enable its use for transmitting critical data. TTEthernet introduces a decentralized clock synchronization paradigm enabling the use of time-triggered Ethernet messaging appropriate for hard real-time applications. TTEther- net can also provide two forms of event-driven communication, therefore accommodating the full spectrum of traffic criticality levels required in IMA architectures. This paper explores the application of TTEthernet technology to future IMA spacecraft architectures as part of the Avionics and Software (A&S) project chartered by NASA's Advanced Ex- ploration Systems (AES) program.

Active-Active Firewall Cluster Support in Openbsd
Active-Active Firewall Cluster Support in OpenBSD David Gwynne School of Information Technology and Electrical Engineering, University of Queensland Submitted for the degree of Bachelor of Information Technology COMP4000 Special Topics Industry Project February 2009 to leese, who puts up with this stuff ii Acknowledgements I would like to thank Peter Sutton for allowing me the opportunity to do this work as part of my studies at the University of Queensland. A huge thanks must go to Ryan McBride for answering all my questions about pf and pfsync in general, and for the many hours working with me on this problem and helping me test and debug the code. Thanks also go to Theo de Raadt, Claudio Jeker, Henning Brauer, and everyone else at the OpenBSD network hackathons who helped me through this. iii Abstract The OpenBSD UNIX-like operating system has developed several technologies that make it useful in the role of an IP router and packet filtering firewall. These technologies include support for several standard routing protocols such as BGP and OSPF, a high performance stateful IP packet filter called pf, shared IP address and fail-over support with CARP (Common Address Redundancy Protocol), and a protocol called pfsync for synchronisation of the firewalls state with firewalls over a network link. These technologies together allow the deployment of two or more computers to provide redundant and highly available routers on a network. However, when performing stateful filtering of the TCP protocol with pf, the routers must be configured in an active-passive configuration due to the current semantics of pfsync. -

Generating Synthetic Voip Traffic for Analyzing Redundant Openbsd
UNIVERSITY OF OSLO Department of Informatics Generating Synthetic VoIP Traffic for Analyzing Redundant OpenBSD-Firewalls Master Thesis Maurice David Woernhard May 23, 2006 Generating Synthetic VoIP Traffic for Analyzing Redundant OpenBSD-Firewalls Maurice David Woernhard May 23, 2006 Abstract Voice over IP, short VoIP, is among the fastest growing broadband technologies in the private and commercial sector. Compared to the Plain Old Telephone System (POTS), Internet telephony has reduced availability, measured in uptime guarantees per a given time period. This thesis makes a contribution towards proper quantitative statements about network availability when using two redun- dant, state synchronized computers, acting as firewalls between the Internet (WAN) and the local area network (LAN). First, methods for generating adequate VoIP traffic volumes for loading a Gigabit Ethernet link are examined, with the goal of using a minimal set of hardware, namely one regular desktop computer. pktgen, the Linux kernel UDP packet generator, was chosen for generating synthetic/artificial traffic, reflecting the common VoIP packet characteristics packet size, changing sender and receiver address, as well as typical UDP-port usage. pktgen’s three main parameters influencing the generation rate are fixed inter-packet delay, packet size and total packet count. It was sought to relate these to more user-friendly val- ues of amount of simultaneous calls, voice codec employed and call duration. The proposed method fails to model VoIP traffic accurately, mostly due to the cur- rently unstable nature of pktgen. However, it is suited for generating enough packets for testing the firewalls. Second, the traffic forwarding limit and failover behavior of the redun- dant, state-synchronized firewalls was examined. -
