    PQ 162: Edge Compute Use Cases And Juniper’s Contrail Edge Cloud (Sponsored)

    What problems are we trying to solve with edge computing, and how might we get those done?

    Our sponsor today is Juniper Networks, and we’re going see if we can answer those edge computing questions in a discussion about Contrail Edge Cloud.

    Our guest is Nick Davey, Product Line Manager at Juniper.

    We discuss:



    * What edge cloud means (pushing compute as close to the workload edge as possible)

    * The components of Juniper’s Contrail Edge Cloud software suite

    * Typical use cases

    * Day 1 operations of Contrail Edge Cloud, including installation, management, and orchestrating edge nodes with the central controller

    * Monitoring Contrail Edge Cloud performance and end user experience

    * Exploring Tungsten Fabric as an open-source option

    * More

    PQ 161: Inside Juniper’s Programmable Silicon (Sponsored)

    PQ 161: Inside Juniper’s Programmable Silicon (Sponsored)

    In today’s sponsored show with Juniper Networks, we dive into the world of silicon and ASICs. Our guest is Chang-Hong Wu, a VP and Juniper Fellow.







    The Packet Pushers start the conversation by breaking down the differences between ASICs, FPGAs, and NPUs.







    We discuss how Juniper uses both custom and merchant silicon in its gear. We also examine how Juniper enables programmability in its Penta ASIC, and how that compares to its fixed-pipeline Express ASIC.







    Chang-Hong dives into the programmability features and capabilities of the Penta, and explains how use cases determine which ASIC Juniper chooses to go in which devices.







    He also discusses advanced silicon designs such as silicon photonics and liquid cooling.







    This episode is a great opportunity to get up to speed on networking ASICs.

    PQ 160: Inside ArcOS®: The Internet-Scale, Carrier-Grade Network OS (Sponsored)

    PQ 160: Inside ArcOS®: The Internet-Scale, Carrier-Grade Network OS (Sponsored)

    Whitebox network hardware paired with disaggregation has created a market for network operating systems.

    One of the latest entrants to that market is Arrcus, which launched in 2018 with guns blazing, claiming that its ArcOS® NOS is so strong it should be mentioned in the same breath as operating systems from Cisco, Juniper, and Arista.

    Today, Arrcus has sponsored the podcast, and we’re going to have a discussion about ArcOS®. Why another NOS? What’s special about ArcOS®? What use cases is it best suited for?

    Joining us from Arrcus are Keyur Patel, CTO and Murali Gandluru, VP of Product Management.

    We discuss how ArcOS® was designed from first principles to support routing and switching, and is built around a microservices, scale-out architecture.

    We also examine how it meets emerging demands for 5G and distributed data center and edge architectures; the different chipsets it can run on; how it differentiates itself from network OSs from Cisco, Arista, and others; and look at key use cases.

    PQ 159: The SATCOM Primer For Network Engineers

    PQ 159: The SATCOM Primer For Network Engineers

    In Priority Queue 154, we chatted with PC Drew about the challenges of standing up a fully operational network in the middle of nowhere.

    That’s standard operating procedure for the military as they fulfill their combat and humanitarian missions around the world.

    In this episode, we’re going to go deeper on one facet of that conversation, satellite communications. PC Drew is back, and he brought along a colleague, Evander Cook, to educate us on SATCOM.

    PC is Chief Technology Officer at SchoolBlocks, and Evander is Director of Network Operations at the United States Marine Corps.

    We discuss basic concepts including frequency bands, TDMA vs. FDMA, satellite coverage areas, and the relationship between signal quality and signal power.

    PC and Evander also explain how different satellite orbits affect network design, the different kinds of military and commercial services available, and how to account for moving vehicles in satellite communications.

    PQ 158: Introducing NRE Labs For Network Automation Training

    PQ 158: Introducing NRE Labs For Network Automation Training

    One problem with learning networking technology is all the work it takes to set up your lab. Creating a virtualization environment, fighting with images, tweaking performance, building out the connections, and so on.

    What if there was a tool that handled the set up burden for you? A tool where you could jump right in and start learning?

    Our guests today tell us about a new online tool that does just that. Called NRE Labs, this Web site provides education and training for network automation.

    You can learn the basics of YAML, Git, and working with APIs, try out automation tools, walk through lessons, or simply experiment with virtual instances of real networking interfaces.

    Developed and supported by Juniper Networks, NRE Labs is free and open source, and welcomes contributions to the project. You don’t have to register or even log in to use the site; just show up and jump in.

    Matt Oswalt and Derick Winkworth, both Product Marketing Managers and Juniper, are two of NRE Labs’ creators. They join us on the podcast to walk us through the site.

    PQ 157: How Cisco Built A Carrier-Grade Network OS (Sponsored)

    PQ 157: How Cisco Built A Carrier-Grade Network OS (Sponsored)

    On today’s Packet Pushers episode, we dive into the guts of Cisco’s IOS-XR. What does it mean for IOS-XR to be carrier-grade? What kinds of problems need to be solved by large service providers? How does the architecture of IOS-XR solve them?

    Cisco is our sponsor for this deconstruction of the NOS. Our guests are Jag Tangirala, Principal Engineer; and Praveen Bhagwatula, Distinguished Engineer.

    We start by examining the scalability, performance and reliability requirements that carries and service providers demand, and then drill into IOS-XR’s architecture.

    We break out the control, data, management and infrastructure planes and look at the role of abstraction in a network OS.

    Our guests delve into what state means in the context of a network OS. We look at how IOS-XR captures and communicates state to the processes that need it using tools such as SysDB and an event notification system.

    The discussion also tracks what happens if a process crashes and how the system recovers, and we look at how IOS-XR gets updated.

    Join us for a truly deep dive into this OS. And get more details on IOS-XR at @xrdocs.io.
