The Evolution of Network Switching
How many of Juniper's switches are L2/L3
What is ALL SWITCHES!
This layer of the campus architecture connects end-user devices like computers and phones
What is the Access Layer?
In a modern data center, this layer connects directly to servers and storage devices, forwarding traffic North
What is Leaf
This protocol is used in switches to synchronize clocks across network devices with sub-microsecond accuracy, critical for applications like financial trading and industrial automation.
What is PTP?
Juniper’s switches and routers run on this custom-built operating system, which is based on FreeBSD and known for its modular architecture and high reliability.
What is Junos OS?
This early networking device operated at Layer 1 of the OSI model and simply forwarded all incoming data to every port, regardless of the destination.
What is a hub?
This layer provides high-speed, resilient connectivity between distribution switches and the data center or WAN
What is the Core?
This layer interconnects all leaf switches in a data center, ensuring high-speed, low-latency communication between devices.
What is Spine?
This security protocol encrypts Ethernet frames at the data link layer, protecting traffic between switches without impacting higher-layer protocols.
What is MACsec?
Juniper’s AI-driven virtual network assistant shares its name with a friendly robot that helps troubleshoot and optimize networks.
What is Marvis?
This device operates at Layer 2 and uses MAC addresses to forward data only to the correct destination port, reducing unnecessary traffic
What is a Bridge?
This layer aggregates traffic from multiple access switches
What is the Distribution/ Aggregation Layer?
What is a deep buffer switch?
This Juniper technology allows interconnected switches to operate as a single logical device, simplifying management and enabling high availability in campus and branch networks.
What is Virtual Chassis
This co-founder of Mist AI is not only a pioneer in AI-driven networking—but also a part-time vinter, proving that even network visionaries enjoy a good cabernet
What is Bob Friday?
This device replaced bridges in most networks, offering multiple ports and faster forwarding decisions based on MAC address tables.
What is an L2 Switch?
In Juniper’s branch architecture, this cloud-managed switch series is fanless, designed for quiet environments and compact deployments
What is EX4100-F
What QFX and EX have the same box
QFX5120 and EX4650
This networking concept allows switches to segment a physical network into multiple logical networks, each with its own broadcast domain.
What is a VLAN (Virtual Local Area Network)?
Juniper Mist’s platform collects telemetry across every layer of the network—from client to cloud—and integrates with tools like Zoom and ServiceNow to speed up root-cause analysis. This end-to-end visibility is part of what Juniper calls this kind of networking.
What is AI-native networking?
This type of switch combines MAC-based forwarding with IP routing capabilities, allowing it to switch traffic within VLANs and route traffic between them—often used in enterprise networks to simplify architecture and reduce latency.
What is an L2/L3 switch?
This Juniper switch is designed for rugged environments like outdoor campuses or industrial branches, featuring a fanless design, extended temperature range (-40°C to +75°C), PoE++ support, and full Layer 2/3 capabilities
What is EX4100-H
Juniper’s data center switches use this control plane protocol to automate and scale EVPN-VXLAN fabrics, enabling plug-and-play leaf and spine deployments with minimal manual configuration.
What is Apstra?
This unique identifier, assigned to every device’s network interface card, is used by switches to determine where to forward frames at Layer 2 of the OSI model.
What is a MAC address?
Juniper’s virtual assistant Marvis recently got an upgrade with this type of AI framework, allowing it to act more autonomously and collaborate across network domains like wired, wireless, WAN, and applications.
What is agentic AI?
