Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.

Building DataCenter networks with VXLAN BGP-EVPNCisco Canada
The session specifically covers the requirements and approaches for deploying the Underlay, Overlay as well as the inter-Fabric connectivity of Data Center Networks or Fabrics. Within the VXLAN BGP-EVPN based Overlay, we focus on the insights like forwarding and control plane functions which are critical to the simplicity operation of the architecture in achieving scale, small failure domains and consistent configuration. To complete the overlay view on VXLAN BGP-EVPN, we are going to the insides of BGP and its EVPN address-familiy and extend to about how multiple DC Fabric can be interconnected within, either as stretched Fabrics or with true DCI. The session concludes with a brief overview of manageability functions, network orchestration capabilities and multi-tenancy details. This Advanced session is intended for network, design and operation engineers from Enterprises to Service Providers.

Tech Talk by John Casey (CTO) CPLANE_NETWORKS : High Performance OpenStack Ne...nvirters
OpenStack is HOT! No doubt about it. A recent survey by The New Stack and The Linux Foundation shows OpenStack as the most popular open source project ahead of other hot projects like Docker and KVM. OpenStack is now taking its rightful place as the open source cloud solution for enterprises and service providers.
To date OpenStack networking has not yet achieved the performance, scalability and reliability that many large enterprises demand. CPLANE NETWORKS solves that problem by delivering secure multi-tenant virtual networking that overcomes the limitations of the standard Neutron networking service. By making all networking services local to the compute node and achieving near line-rate throughput, CPLANE NETWORKS Dynamic Virtual Networks (DVN) delivers mega-scale networking for the most demanding application environments.
In this session John Casey will cover the basics of DVN and explain how CPLANE NETWORKS achieves "at scale" network performance within and across data centers.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

PE to CE connectivity type – Overhead associated with RIP V2, BGP-4 and OSPF. Number of neighbors ? Timer adjustment consumes more CPU
# of provisioned VRFs – the more VRFs, the more FIB, RIB structures to deal with – IP Background process
# of VPN clients/routes – more routes, more scanning (for example BGP scanner)
# of backbone peers – more peers, more updates/keepalives etc, more sessions to maintain
Packet forwarding - process switching takes more CPU due to lookup etc. CEF builds cache based on topology
Should mention here that the ESR (10000) and the OSR (7690) will also support PE functionality but are not included at this point. Should also note the GRP-2 (1Ghz processor)
