- With Topology-Independent In-Service Software Upgrades (ISSU), the QFX5100 can dramatically reduces network maintenance windows. The QFX5100 is the only product in its class to offer true-topology independent ISSU. The typical approach to ISSU for ToR / access switches is to rely on the resilient backup switch in the network to provide service continuity while a switch is being upgraded and rebooted. This results in: Network performance degradation for the during of the switch upgrade as one element of the resilient pair is out of service during the upgrade process Network resiliency risk as resiliency is compromised during the upgrade process Long maintenance windows and operations inefficiencies as only one switch can be updated at a time, requiring a sequential upgrade process. With topology-independent ISSU, there is no dependency on a resilient backup switch for hitless software upgrades. During software upgrades there is no impact on network performance and no risk to network resiliency as all switches continue to operate during the upgrade process. Also, there is no need to plan for long maintenance windows as all switches can be upgraded simultaneously. [click] The QFX5100 is built on an x86 processor running a hardened Linux Kernal. The Junos operating system runs in a Kernal Based Virtual Machine. To upgrade the operating system, an upgrade command is issued from the master Junos VM (Master). [click] A new Junos disk image is created and verified, then launched as a new backup Junos VM. [click] Then the system waits for the Packet Forwarding Engines to synchronize, before swapping roles (detaching devices from the current master and attaching devices to backup). [click] Once the upgrade is complete the current master Junos VM is shut down after delivering a truly seamless software upgrade. [click] Topology-Independent In-Service Software Upgrade (TISSU): With its Intel core processor, the QFX5100 switches allow Junos OS to run within a virtual machine (VM) on Linux. Junos OS runs in two separate VMs in active and standby pairs; during software upgrade cycles, the switches seamlessly move to the newer software version while maintaining intact data plane traffic. This true Topology- Independent ISSU, an industry-first software upgrade feature for a fixed-configuration top-of-rack switch, is supported across all Layer 2 and Layer 3 protocols and doesn’t need the support of any other switches to perform an image upgrade.
- The QFX5100 provides dynamic buffer utilization monitoring and reporting with an interval of 8 microseconds to provide microburst and latency insight. It calculates both queue depth and latency, and logs messages when configured thresholds are crossed. Interface traffic statistics for both unicast and multicast traffic can be monitored at one second granularity. The data can be viewed via CLI, system log, or streamed to external servers for more analysis. Supported reporting formats include Java Script Object Notification (JSON), CSV and TSV. These files can be consumed by orchestration systems, SDN controllers, or network management applications (such as Juniper Networks Junos Space Network Director) to make better network design decisions and identify network hotspots.

- VCF is 20-members system, and we do not want flood the traffic for BUM traffic. Compared with Virtual Chassis (VC), which leverages source tree forwarding, Virtual Chassis Fabric instead uses multiple bidirectional Multicast Distribution Trees (MDT) for Broadcast, Unknown Unicast, and Multicast traffic. For each node in Virtual Chassis Fabric, the Virtual Chassis Control Protocol (VCCP) calculates a minimum cost tree rooted at each node. The calculation is based on breadth-first search (BFS) algorithm. Each bidirectional tree reaches every other node with the best metric in terms of number of replication points and latency. For a N-member Virtual Chassis Fabric, each VCCP instance will calculate N bidirectional trees. One such tree is shown in the figure below. A couple of benefits I want to call out: 1) 2) The multiple Multicast Distribution Trees will be shared by traffic on different VLANs in the Virtual Chassis Fabric, achieving load balance at a macro level. breadth-first search (BFS) is a strategy for searching Multiple MDTs are calculated One (1) minimal cost tree rooted at each node is calculated using BFS algorithm (cost == latency) Total of N trees calculated in this release Known Multicast: Each multicast next-hop (IPMC) is assigned to tree-id MC NH contains cluster-wide receiver port list {pfe1/port1, pfe2/port2,,,}
