Architectural Options for Metro Carrier-Ethernet Network Buildout: Analysis &...Vishal Sharma, Ph.D.
This workshop is one of the first that we're aware of to give a detailed taxonomy & analysis of deployment options for Carrier Ethernet-based metro/access networks, in one place. We elaborate each option addressing questions like: network architectures possible? Is other supporting technology needed? Or, is it standalone for the applications/services a provider might run, and so on.
China Telecom has been migrating from ADSL to fiber technologies like EPON and GPON to meet increasing broadband subscriber and bandwidth demands, piloting EPON in 2005 and making it a core access technology due to its maturity and interoperability. They aim to accelerate FTTH deployment through projects like "Broadband China, Optical City" to reach 100 million FTTH homes by 2015 using EPON and GPON, while also starting rollout of 10G-EPON to improve bandwidth for multi-dwelling units.
MPLS-based Metro Ethernet Networks Tutorial by KhatriFebrian
This document provides an overview of traditional metro Ethernet networks and carrier Ethernet services. It discusses:
1. How services were traditionally identified using VLAN IDs and Q-in-Q tagging which allowed for more services by preserving customer VLAN tags.
2. Forwarding was done through dynamic MAC learning in switch databases, which posed scaling issues as databases in all switches had to contain all MAC addresses.
3. Resiliency was provided by variants of spanning tree protocol, but these resulted in unused bandwidth during topology changes.

Active optical networks have advantages over passive optical networks in terms of bandwidth. With AONs, bandwidth allocation is flexible and each subscriber can be allocated from 100 Mbps to 1 Gbps. In contrast, PON bandwidth is determined by the splitting factor, with each subscriber receiving less bandwidth depending on the number of subscribers on the network. Upgrading bandwidth is also simpler with AONs, as subscribers can be upgraded by changing fiber optic leads or boards. However, PONs allow for higher subscriber counts due to their point-to-multipoint topology.
Carrier Ethernet addresses limitations of legacy telecommunications technologies by providing flexible bandwidth scalability through Ethernet. It allows bandwidth to be added remotely up to the port speed without technology changes. This enables services tailored to subscriber needs rather than fixed increments. Carrier Ethernet also reduces costs by using the same Ethernet technology across networks and simplifying operations. It can be delivered over various transport network technologies to provide services like E-Line, E-LAN, and E-Tree connectivity.

This document discusses Huawei's fiber-to-the-x (FTTx) solutions and digital subscriber line (DSL) technologies for network migration. It highlights Huawei's innovations that facilitate broadband deployment over copper lines and fiber networks. These include vectoring, G.fast, and all-in-one outdoor cabinets. The document also outlines Huawei's N2510 network testing platform for accurate fault location, demarcation, and proactive network maintenance.
Other test equipment providers sell LTE capabilities separately, but following our all-inclusive model, we’ve included LTE testing for every BreakingPoint CTM, existing or new. (All it takes is a firmware update.) The combination of such large-scale testing and our all-in-one pricing model drops the cost per UE to under $0.25. That’s right — less than 25 cents.
Contrast that to the $1,000 price tag mentioned above, and it’s not hard to see the impact it makes. The fact that we can now offer our customers the most cost-effective option of simulating millions of concurrent users with real application traffic (plus security attacks and fuzzing, of course) means that they can now validate their LTE network configurations at scale before going live. This is something they simply could not have done before.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
