This document proposes using Datagram Transport Layer Security (DTLS) over Stream Control Transmission Protocol (SCTP) as a security mechanism for Diameter over SCTP. It motivates this by noting limitations of Transport Layer Security (TLS) over SCTP and how DTLS overcomes them. It also proposes mapping all Diameter messages to SCTP stream 0 with the unordered flag set to avoid head-of-line blocking while maintaining simplicity and performance. The document asks the Diameter working group if this is something that should be standardized and whether it should be done in an update to RFC 3588 or a separate document.
DHCP (Dynamic Host Configuration Protocol) is a standard protocol that allows devices on a network to obtain IP addresses and other network configuration parameters automatically from a DHCP server. The DHCP client-server model involves clients broadcasting requests and servers responding with offers of IP addresses and network information. Servers track IP address leases in databases to allow for dynamic allocation and recycling of addresses over time as clients join and leave the network. DHCP supports both static and dynamic allocation of IP addresses to provide flexibility in network configuration.
WAP (Wireless Application Protocol) is a standard for accessing information on mobile devices like phones. It uses WML (Wireless Markup Language) instead of HTML. WAP has a layered architecture including application, session, security, transaction, and transport layers. It allows access to the internet from mobile devices in a standardized way and is supported by most phone manufacturers and wireless networks.
FatPipe Networks is an established provider of SD-WAN and hybrid-WAN solutions, having developed the concept over 15 years ago with numerous patents.

FatPipe offers centralized management and policy control, application-aware routing, security features like encryption, and sub-second failover of voice and video sessions. It provides a competitive advantage through experience, product maturity, and intellectual property protections over newer startups in the space.
Dynamic Host Configuration Protocol (DHCP) automatically provides devices on a network with IP addresses and other configuration information from a DHCP server. A DHCP client broadcasts a request, the DHCP server receives it and offers an available IP address with a lease time. The client then sends a request for that IP address and the server confirms by sending an acknowledgment. DHCP reduces issues caused by static IP address conflicts and makes managing IP addresses easier for network administrators.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

High Performance Global Trading Infrastructure Services
QuantHouse enables our customers to manage the ever-increasing demand for
low latency market data and to meet the changing requirements of today’s trading
environment with new trading venues, fragmentation of liquidity and rapidly increas-
ing volumes of data, QuantHouse has developed an end-to-end product offering
encompassing data capture within the exchange, ultra-fast data normalization and
dissemination over QuantHouse’s proprietary fiber optic network.
DATA CAPTURE:
This occurs within the exchange site or nearest proximity venue.
Data is captured as close to the source as possible and this is the first step towards lowest latency
provision either in the data centre, or Globally, via our fibrer optic backbone.
DATA NORMALIZATION:
Feedhandler technology, hosted within the exchange, developed using C++ under Unix, to create
highly optimized software, including native multi-threading to take advantage of multi-core proces-
sors and provide optimal decoding times and throughput.
DATA DISSEMINATION:
Data is sourced, normalised and distributed from the exchange and multiple global exchanges and
aggregated in each data center to provide a true end-to-end “speed of light” advantage for proximity
or Global data.
Since we design, implement and maintain every single element of the market data chain, we can offer
our customers an ultra-low-latency solution; accessible through a connection to a single POP on our
network; using a single API;
making it very easy to access any market using the same application.
Knowing that every financial institution is unique, we offer different solutions:

2. Direct Market Access - Market data captured at the closest point to the exchange
QuantHouse captures data from within the exchange sites and delivers this using the fastest path
available.
Feedhandler Layer - Market data normalization at the closest point to the exchange.
Located in QuantHouse hosting facilities, FeedHandler servers decode, normalize and disseminate
either direct or 3rd party vendor’s market data.
QuantHouse’s FeedHandlers are based on an advanced proprietary middleware – FeedOS – which is
the result of several years of Research & Development.
This object-oriented, natively multi-threaded software written in C++, has been carefully crafted to
handle large volumes of data while focusing on low latency. A proprietary protocol has been designed
to efficiently carry market data in various configurations (TCP, UDP, IPC) and runs on Linux 64bit
servers. QuantHouse technology, when combined with the latest processor chips available, provides
enough decoding power to handle any market data feed with sub-millisecond latency and scalability
for message rate growth and the future.

3. QuantFEED - The End to End ultra low latency market data solution
Proprietary Fiber Optic Network - The fastest market data dissemi-
nation
Using the latest technology available; 10Gbps Networks and peak data capacity links ensure
capacity and speed when you need it.
QuantHouse’s global network transports normalized market data around the globe at the
speed of light.
QuantHouse has built its own fiber optic network. We manage and control every hop including network
components, such as Routers and Switches used in our network; as well as selectively procuring the
fastest fiber optic links between sites.
FrontEnd Layer - Market data aggregation closest to the customer
Located in QuantHouse hosting facilities, dedicated to a single client (QuantFEED
Premium) or shared (QuantFEED Classic), FrontEnd servers are responsible for
aggregating feeds coming from several FeedHandlers.
Like the FeedHandlers and other QuantFeed servers, a FrontEnd server is based on
QuantHouse custom-made middleware. The role of a FrontEnd server is to aggregate feeds from
several FeedHandlers. Various configuration parameters allow fine-tuning of the server
depending on the usage: the number of CPUs, the amount of memory available, how many feeds are
aggregated, how many clients are expected to connect, which protocols and requests are supported,
etc.
QuantHouse API - Easy Market data integration through a single API
Available in three different languages, Java, C++ and C# the QuantHouse API will allow you to
receive normalized ultra low latency feeds and integrate our data with your
software design choices.
Several solutions exist to connect to the FrontEnd servers: proprietary protocol (C++, Java and C#
API) or standard FIX protocol. Once you have integrated the QuantHouse API, you are able to receive
every feed from any global market asset class - either from QuantHouse Direct Market Access (DMA)
or from 3rd party vendors - without any further development. Richly featured and provided with
sample applications, QuantHouse’s API is all you need to receive the fastest ultra low latency nor-
malized feed. The API allows four types of requests: historical data, referential data, snapshot and
subscription.
QuantFEED Software - Our technology at your service
Complete and boost your existing infrastructure with QuantHouse’s best- of- breed
software.
QuantHouse’s FeedHandler and FrontEnd software can allow you to optimize your own market access.
By adopting QuantHouse’s powerful software, you can focus on your core business, and avoid wasting
resources in custom software development and maintenance. QuantHouse FeedHandler and Fron-
tEnd servers can be deployed at the client site. The feeds can be sourced from the exchanges using
an existing client connection. Various configuration setups are available depending on requirements.
QuantFEED Client side solutions - Tailor your solution
Every financial institution is unique; therefore, QuantHouse uses a consultative approach to provide
its clients with tailor-made solutions based on FeedOS - QuantHouse’s proprietary middleware tech-
nology.
