IPv6 is the latest version of the Internet Protocol that provides identification and location for computers on networks. It was developed to address the problem of IPv4 address exhaustion, as IPv4 addresses were running out. IPv6 is intended to eventually replace IPv4 and provides a vastly larger 128-bit address space compared to IPv4's 32-bit addresses. Key features of IPv6 include new header format, large address space, built-in security, prioritized traffic delivery, autoconfiguration, and mobility support.

Multi-domain Orchestration leveraging the Application-Layer Traffic Optimizat...Danny Alex Lachos Perez

Evolving 5G network scenarios will have to deal with new multiple administrative domain (aka multi-domain) orchestration models. Based on a new broker-plane approach on top of per-domain management and orchestration functions, we present a Multi-domain orchestration prototype capable to coordinate the delivery of a multi-operator End-to-End Network Service (E2ENS) that combines per-domain paths and network functions for a given service request. Our prototype implementation retrieves local information about topology and resources from each Multi-domain Orchestrator (MdO) to offer after inter-domain added value services in the form of abstract Map Services. These map abstractions are easily consumable through developer-friendly REST APIs based on the Application-Layer Traffic Optimization (ALTO) standard protocol.

Global routing validation involves facilitating the validation of routing information on a global scale through two main systems - the Internet Routing Registries (IRR) and the Resource Public Key Infrastructure (RPKI). Routing information such as routing policies, autonomous system numbers, and IP prefixes should be publicly available in a common format to allow for global validation. The RPKI system uses digital certificates to authoritatively associate network resources like IP addresses and autonomous system numbers to their legitimate owners and allows identification of which autonomous systems have permission to originate those addresses. Implementing RPKI and origin validation helps secure routing and prevent route hijacking.

The document discusses the Sky-X technology, which replaces TCP with the Xpress Transport Protocol (XTP) for satellite communication. The Sky-X gateway intercepts TCP connections and converts data to XTP for transmission over the satellite link, then back to TCP. This improves performance over satellite links by optimizing for high loss environments compared to TCP. The Sky-X system allows networks to take full advantage of satellite bandwidth and provides fast, reliable data transfer and multicast file transfers without requiring client/server modifications.

Sky X Tech PPT by Manoj DattManoj Datt

Manoj Datt presented on the Sky X technology for improving performance over satellite links. The Sky X system uses Xpress Transport Protocol (XTP) and a Sky X Gateway to optimize data transfer speeds over satellites. TCP is not well suited for satellite conditions that involve long delays and high bit errors. The Sky X Gateway replaces TCP with XTP for the satellite hop and back to TCP on the ground, improving speeds by 3-10x without any changes needed to end devices and applications. This Sky X architecture provides fully reliable, fast transmissions over satellites.

Ipv6 routingsrikrishna mallavarapu

Routing protocols have been redefined to support IPv6. There are two types of routing protocols: distance vector protocols which advertise routes to neighbors (e.g. RIPng), and link-state protocols which advertise link states (e.g. OSPFv3). Routing protocols can be interior (within an autonomous system) or exterior (between autonomous systems). Common interior protocols are RIPng and OSPFv3, while BGPv4 is commonly used as the exterior protocol.

The network layer is responsible for transporting data between hosts on different networks. It handles tasks like addressing, routing, fragmentation, and quality of service. The main network layer protocol is IP, which uses addresses and routing to deliver packets in an unreliable, connectionless manner. IPv6 was created to replace IPv4 due to its limited address space and remove unnecessary features to simplify processing. During the transition, IPv6 can be tunneled inside IPv4 packets to allow communication between IPv6 and IPv4 networks.

This OrionX's 14th semi-annual report on the state of the cryptocurrency mining market. The report focuses on Proof-of-Work cryptocurrencies since those use substantial supercomputer power to mint new coins and encode transactions on their blockchains. Only two make the cut this time, Bitcoin with $18 billion of annual economic value produced and Dogecoin with $1 billion. Bitcoin has now reached the Zettascale with typical hash rates of 0.9 Zettahashes per second. Bitcoin is powered by the world's largest decentralized supercomputer in a continuous winner take all lottery incentive network.

National Fuels Treatments Initiative: Building a Seamless Map of Hazardous Fu...Safe Software

The National Fuels Treatments Initiative (NFT) is transforming wildfire mitigation by creating a standardized map of nationwide fuels treatment locations across all land ownerships in the United States. While existing state and federal systems capture this data in diverse formats, NFT bridges these gaps, delivering the first truly integrated national view. This dataset will be used to measure the implementation of the National Cohesive Wildland Strategy and demonstrate the positive impact of collective investments in hazardous fuels reduction nationwide. In Phase 1, we developed an ETL pipeline template in FME Form, leveraging a schema-agnostic workflow with dynamic feature handling intended for fast roll-out and light maintenance. This was key as the initiative scaled from a few to over fifty contributors nationwide. By directly pulling from agency data stores, oftentimes ArcGIS Feature Services, NFT preserves existing structures, minimizing preparation needs. External mapping tables ensure consistent attribute and domain alignment, while robust change detection processes keep data current and actionable. Now in Phase 2, we’re migrating pipelines to FME Flow to take advantage of advanced scheduling, monitoring dashboards, and automated notifications to streamline operations. Join us to explore how this initiative exemplifies the power of technology, blending FME, ArcGIS Online, and AWS to solve a national business problem with a scalable, automated solution.

In the fast-changing world of artificial intelligence, the industry is deploying more AI compute at the edge. But the growing diversity and data footprint of transformers and models such as large language models and large multimodal models puts a spotlight on memory performance and data storage capacity as key bottlenecks. Enabling the full potential of AI in industries such as manufacturing, automotive, robotics and transportation will require us to find efficient ways to deploy this new generation of complex models. In this presentation, Florentino explores how memory and storage are responding to this need and solving complex issues in the AI market. He examines the storage capacity and memory bandwidth requirements of edge AI use cases ranging from tiny devices with severe cost and power constraints to edge servers, and he explains how new memory technologies such as LPDDR5, LPCAMM2 and multi-port SSDs are helping system developers to meet these challenges.
