Enabling 5G X-Haul with Deterministic Ethernet - A TransPacket whitepaperIvar Søvold
Transpacket (www.transpacket.com) explores the concept of Ethernet X-Haul in a newly released whitepaper. Discussed extensively in the mobile industry in connection with 5G, the idea is to have an Ethernet based converged transport network serving multiple purposes including fronthaul and backhaul. The whitepaper presents the RAN architectures under consideration for 5G, and their consequences in terms of requirements for the transport network. It further describes how an innovative Ethernet scheduling mechanism is required to support deterministic Ethernet, and to fully achieve an 5G Ethernet X-Haul. It also introduces two use cases, namely Ethernet Crosshaul, and Indoor Coverage, which demonstrate the added value of deterministic Ethernet for mobile transport applications.

The features of a communication technology that yield the properties of interoperability and reliability can be visualized in layers: technical (at the level of bytes), syntactic (at the level of messages), semantic (at the level of data, i.e. what the messages refer to), and so on. Real-world systems require at least data-level interoperability and reliability. The question is: will you acquire something that already supports those capabilities, or will you build it atop something that doesn't? This talk compares and contrasts DDS and AMQP as technology exemplars in each category.

Suppliers of C4I, C2, Cyber, ISR and sensor and weapons platforms are challenged to meet commercial pressure from defense procurement for more capability at lower cost, and from acquisition officials for increasing interoperability across their combat systems in order to be able to enable new system capability through Information Dominance (ID).
RTI will present an architecture and its Connext solution, designed to meet these twin imperatives. Built upon proven open technology, Connext is a foundational system architecture that delivers significant productivity gains in integration, while also enabling discovery and rapid assimilation of existing system entities, potentially from 3rd party suppliers or already deployed in the field of operation.
Given the unique requirements of tactical system-of-systems, the architecture must support both real-time combat systems as well as brigade and command HQ enterprise style systems, bringing them together in a scalable, dynamic, and flexible framework. Connext addresses the performance and scale impedance mismatch between these disparate systems types, and delivers the ability to develop a common infrastructure that runs over DIL (Disconnected Intermittent Loss) communications as well as it does over Ethernet, putting minimal strain on the communications interfaces and maximizing information exchange.
The Connext foundation is in use in over 400 defense programs globally with over 350,000 licensed deployments. It has been approved by the US DoD to TRL9 (Technology Readiness Level).
In 2003, the DoD CIO published the "Net-Centric Data Strategy".

A New Analysis for Wavelength Translation in Regular WDM NetworksVishal Sharma, Ph.D.
We present a new analysis of wavelength translation in
regular, all-optical WDM networks, that is simple, computationally
inexpensive, and accurate for both low and high
network loads. In a network with
k
wavelengths per link,
we model the output link by an auxiliary
M/M/k/k
queueing
system. We then obtain a closed-form expression for
the probability
P succ
that a session arriving at a node at a
random time successfully establishes a connection from its
source node to its destination node. Unlike previous analyses,
which use the link independence blocking assumption,
we account for the dependence between the acquisition of
wavelengths on successive links of the session’s path. Based
on the success probability, we show that the throughput per
wavelength increases superlinearly (as expected) as we increase
the number of wavelengths per link; however, the
extent of this superlinear increase in throughput saturates
rather quickly. This suggests some interesting possibilities
for network provisioning in an all-optical network. We verify the accuracy of our analysis via simulations for the torus
and hypercube networks.

A Survey of Recent Advances in Network Planning/Traffic Engineering (TE) ToolsVishal Sharma, Ph.D.
Designing & managing operational IP networks is a complex, multi-dimensional
task. A fundamental problem before carriers today
is to optimize network performance by better resource allocation to traffic demands.
This requires a systematic evaluation of options, a thorough scenario analysis,
and foolproof verification of network designs, all of which are increasingly
possible only with help from automated TE and planning tools.
In the past few years, significant advances have been made in enhancing existing
tools and developing new ones that help providers rapidly identify potential
performance problems, experiment with solutions, and develop robust designs.
Several techniques from optimization theory, linear programming, and
models of effective bandwidth calculation have been incorporated in such
tools, as have detailed models of several vendor systems.
We present a comparative analysis and an overview of key features of some key
commercially available network planning/TE tools, and outline how
they could be leveraged by carrier network engineering/planning
organizations to perform detailed network analysis, proactive/reactive
TE, and network design.
We first give an overview of the architecture, design philosophy, and canonical
features of modern design tools, and then focus on new enhancements to some
popular tools
as well as key distinguishing features of some newly developed ones.
In particular, we focus on decision support tools for IP network planning
and network analysis, including the latest versions from
WANDL, OPNET, Cariden..
We also present a perspective on current outstanding carrier requirements
for TE/planning tools that was synthesized by our conversations with
several leading Tier 1 and Tier 2 carriers.
A fundamental problem before carriers today is to optimize network cost
and performance by better resource allocation to traffic demands. This is especially
important with the packet infrastructure becoming a critical business resource.
The key to achieving this is traffic engineering (TE), the process of
systematically putting traffic where there is capacity, and backbone
capacity management, the process of ensuring that there is enough network
capacity to meet demand, even at peak times and under failure conditions,
without significant queue buildups.
In this talk, we first focus on the TE techniques and approaches used
in the networks of two large carriers: Global Crossing and
Sprint, which represent the two ends of the traffic engineering spectrum.
We do so by presenting a snapshot of their TE philosophy, deployment strategy,
and network design principles and operation.
We then present the results of an empirical study of backbone traffic
characteristics that suggests that Internet traffic is not self-similar at
timescales relevant to QoS. Our non-parametric approach requires minimal
assumptions (unlike much of the previous work), and allows
us to formulate a practical process for ensuring QoS using backbone
capacity management.
(This latter work is joint with Thomas Telkamp, Global Crossing Ltd. and Arman
Maghbouleh, Cariden Technologies, Inc.)
With the rapid growth of IP networks in South-Asia in the past
few years, and the advent of new services and applications -- be they
wireless/wireline broadband Internet access, cable telephony, VoIP, remote
teleconferencing, e-governance, or mobile entertainment -- a key
issue before carriers is how to design and operate their networks as
methodically and as efficiently as possible to maximize both customer
retention and profits.
While several best practices typically emerge from each provider\'s
unique situation and cumulative experience (the "art" of network design), there
are certain operational precepts that systematize and streamline the
complex, multi-dimensional task of designing and managing modern, operational
IP networks (the "science" of network design).
In this talk, we first discuss the overall network design process and the
manner in which control over the network must be exercised at varying
timescales to achieve efficient operation. Next we discuss the
functions that the operational, engineering, and planning teams at a
carrier must typically execute, their inter-relationships, and
the importance/rationale for performing them to optimize network
performance.
We then outline some network design best practices that have evolved
over the past decade, drawing upon examples of carriers such as
Sprint, Global Crossing, AT&T, NTT, and Reliance. We conclude with
a look at some automated traffic engineering and planning tools,
and how they enable carriers to rapidly identify potential
performance problems, rigorously experiment with/evaluate design
options, perform thorough scenario and network analysis, and
develop robust designs.
Multi-Protocol Label Switching has become by far one of the most important Internet technologies of the last 15 years.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

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.

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.
We now look at the requirements of military-grade networks to understand what additional features are needed in networks that are designed for military/defense use.
Having outlined the goals of the DoD ’s net-centric strategy, as well as the key attributes of military-grade networks, we now map these attributes to the features/requirements imposed on the underlying technology, the system and network architecture. We look at this in two parts – focusing first on the implications of the net-centric strategy, and then on the implications of military-grade requirements.
Standardized services refers to having a uniformly accepted definition of core services that serve as the building block for applications running atop them (more on these below). Scalability refers to a service that scales to millions of UNIs (end-points) and MAC addresses, spanning access, local, national, and global networks, with the ability to support a wide bandwidth granularity and versatile QoS options. Reliability refers to the ability to detect and recover from errors/faults without impacting customers, typically with rapid recovery times, as low as 50ms. Hard QoS implies providing end-to-end performance based on rates, frame loss, delay, and delay variation, and the ability to deliver SLAs that guarantee performance that matches the requirements of voice, video, and data traffic over heterogeneous converged networks. Service management implies having carrier-class OAM, and standards-based, vendor-independent implementations to monitor, diagnose, and manage networks offering Carrier Ethernet service.
The services defined by the MEF are in terms of an Ethernet Virtual Connection (EVC), which is defined as an association of two or more User Network Interfaces (UNIs) at the edge of a metro Ethernet network (MEN [1] ) cloud (i.e. subscriber sites), where the exchange of Ethernet service frames is limited to the UNI ’s in the EVC. The MEF defines 3 standardized services: E-Line (a point-to-point EVC), E-LAN (a multipoint-to-multipoint EVC), and E-Tree (a point-to-multipoint “rooted” EVC, where the root(s) can communicate with any of the leaves, but the leaves must communicate with each other only via the root). Thus, an Ethernet Private Line service is built using a point-to-point EVCs, while an Ethernet Private LAN service is built using mp2mp EVCs. [1] Even though the MEF specifications refer to MENs (metro Ethernet networks) this is now a generic term that refers to the Carrier-Ethernet service enabled network, which can span a variety of access, metro, and long-haul networks.
Here we illustrate the 3 services defined by the MEF, explained earlier.
We just described the characteristics of optical Ethernet, which can be used in different parts to provide e2e connectivity. Now these optical Ethernet technology can be used in different parts of the network, access, aggregation and core to provide e2e connectivity.
We also discuss Ethernet use in mobile technology.
