This document provides guidance on investigating, testing, and deploying packet synchronization technologies like IEEE 1588v2 and Synchronous Ethernet for mobile backhaul networks. It addresses common questions around why networks are migrating to packet-based synchronization, the differences from TDM networks, how performance is evaluated, and existing standards. The document emphasizes a three-step approach: investigate technologies and requirements, test equipment and network performance, and then deploy based on guidelines. It aims to help network operators and designers successfully implement physical layer and packet-based synchronization over their carrier Ethernet networks.
T Series Core Router Architecture Review (Whitepaper)Juniper Networks
Juniper Networks® T Series Core Routers have been in production since 2002, with the introduction of the Juniper Networks T640 Core Router. Since that time, T Series routers have evolved to maintain an unequivocal industry lead in capacity (slot, chassis, and system) and operational efficiencies in power and usability. Maintaining this standard has in part been possible due to design decisions made with the very first T Series system. The T Series demonstrates how Juniper has evolved its router architecture to achieve substantial technology breakthroughs in packet forwarding performance, bandwidth density, IP service delivery, and system reliability. At the same time, the integrity of the original design has made these breakthroughs possible. Not only do T Series platforms deliver industry-leading scalability, they do so while maintaining feature and software continuity across all routing platforms. Whether deploying a single-chassis or multichassis system, service providers can be assured that the T Series satisfies all networking requirements.

Getting clocks to agree on the time is tricky. Getting them to agree on the time better than 100 nanoseconds is even trickier.
In this talk I will provide an introduction to the basic principles of the Precision Time Protocol (PTP) and how it can be used to precisely synchronize computers over a LAN.

Tollgrade LightHouse Asset Management Techniques Using Smart Grid SensorsTollgrade Communications
Utilities are finding evermore uses cases and applications for Smart Grid Sensors in their networks. In addition to core applications to help maintain and improve reliability, utilities are increasingly identifying new opportunities and use cases for Smart Grid Sensors to support the objectives of Asset Management teams.
This presentation given at the IEEE PES GM conference in the Asset Management Working Group focuses on specific examples from utility customers using the LightHouse system to support Asset Management for Predictive Maintenance, Substation Monitoring, Capacitor Bank Monitoring, Load Monitoring and Switching at feeder tie points.
This project is concerned with the
design of SoC for detecting and correcting the error which may occur in the memory unit due to
radiation in LEO (Lower Earth Orbit) and due to stuck-at faults in memory unit in space station.
The error free data is feed to the predestined processor using the serial communication protocol
(UART) and perform its function specified in the data input which is sent from the ground station.
The use of synchrophasors for monitoring and improving the stability of power transmission networks is gaining in significance all over the world. The aim is to monitor the system state, to intensify awareness for system stability and to make optimal use of existing lines. This way, system stability can be improved overall and even the transmission performance can be increased. The data from so many PMU’s and PDC’s needs to be collected and directed to proper channels for its efficient use. Thus we need to develop an efficient, flexible and hybrid data concentrator that can serve this purpose. Besides accepting the data from PMU’s, PDC should be able to accept the data also from other PDC. We have designed such a PDC (iPDC) that accepts data from PMU & PDC that are IEEEC37.118 standard compliant.
WAMS architecture with iPDC and PMU at different levels. This architecture enables iPDC to receive data either from a PMU or other iPDC. Both PMU and iPDC from whom the data is being received should be IEEE C37.118 synchrophasor standard compliant. It is hybrid architecture.
iPDC Design
The client server architecture is common in networks when two peers are communicating with each other. Of the two peers (PMU and iPDC) that are communicating with each other in WAMS one acts as a client and the other as a server. Since PMU saves the requests coming
from iPDC by sending data or configuration frames it acts as a server. It listens for command frames from iPDC. PMU-iPDC communication can be either over TCP or UDP communication protocols. On receiving command frames, PMU replies to the iPDC with data or configuration frames according to the type of request.
iPDC functionality is bifurcated as server and client. iPDC as a Client - When iPDC receives data or configuration frames its acts as a client. When acting as a client, it creates a new thread for each PMU or a PDC from whom it is going to receive data/configuration frames. This thread would establish connection between the two communication entities. It handles both TCP and UDP connections. The first frame that the server (PMU/PDC) would receive is the command for sending the configuration frame. When the server replies with the configuration frame, iPDC (client) would generate another request to start sending the data frames. On receiving
such a command frame, the server starts sending the data frames. If there is some change in the status bits of data frame which the client (iPDC) notices, it would take an action. For example if it notices a bit 10 has been set, it would internally send a command to server to send the latest configuration frame.
iPDC as a Server- When iPDC receives command frames from another PDC it would acts as a server. There would be two reserved ports one for UDP and other for TCP on which the PDC would receive command frame requests. Thus PDC now plays the role of PMU waiting
for command frames.

Multimedia streaming over TCP is common in the Internet. Under condition of scarce net- work resource, the rate oscillation due to congestion control degrades the user’s experience. In addition, the data transmisson of multimedia services under the congested network needs to consider the priority of services depending on the application type. While TFWC sup- ports smooth congestion control for real-time multimedia streaming, it cannot provide a high-enough sending rate to the services that require high throughput rather than smooth- ness. In this thesis, I propose Tunable TFWC (TTFWC),

Enhanced Enterprise Intelligence with your personal AI Data Copilot.pdfGetInData
Recently we have observed the rise of open-source Large Language Models (LLMs) that are community-driven or developed by the AI market leaders, such as Meta (Llama3), Databricks (DBRX) and Snowflake (Arctic). On the other hand, there is a growth in interest in specialized, carefully fine-tuned yet relatively small models that can efficiently assist programmers in day-to-day tasks. Finally, Retrieval-Augmented Generation (RAG) architectures have gained a lot of traction as the preferred approach for LLMs context and prompt augmentation for building conversational SQL data copilots, code copilots and chatbots.
In this presentation, we will show how we built upon these three concepts a robust Data Copilot that can help to democratize access to company data assets and boost performance of everyone working with data platforms.
Why do we need yet another (open-source ) Copilot?
How can we build one?

The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.
