The Juniper ACX5448-FAN-AFI is a high-performance fan tray component from the ACX5000 Series of Universal Metro Routers. Designed specifically for the ACX5448 platform, this fan module ensures reliable thermal management in demanding metro environments, supporting high-density interfaces including 48 GbE SFP, 48 10GbE SFP+, 4 40GbE QSFP, and 4 100GbE QSFP28 ports with up to 800 Gbps throughput.
Architecture and Key Components
Powered by Juniper Networks Junos operating system, the ACX5000 line complements Juniper Networks MX Series Universal Routing Platforms through a flexible and scalable service provider and enterprise branch routing portfolio optimized to support rapidly growing mobile, video, and cloud computing applications. The ACX Series introduces Juniper’s proven IP/MPLS leadership from core and edge into the access layers of the network. Maintaining relative simplicity in the access network, the ACX Series supports a rich suite of L2, L3, and IP/MPLS functionality to allow large-scale seamless MPLS networks with simplified service provisioning and operations.
Seamless MPLS
The ACX5000 line of routers supports both Ethernet bridging and MPLS. Growing demands for bandwidth are accompanied by network growth in terms of number of nodes. In some cases, users demand to scale their networks up to tens of thousands of nodes. Seamless MPLS architecture enables scale and service flexibility by decoupling physical topology from transport and service layers. With a seamless MPLS architecture, service providers can leverage their existing investment in MPLS in the core and edge and extend the operational benefit into the access layer. This enables greater network service flexibility and higher scaling parameters of the metro area network (MAN), where Metro Ethernet services can span multiple network segments and be seamlessly terminated at any point of the network or cloud.
Junos OS
A reliable, high-performance, modular network operating system, Junos OS is supported across all of Juniper’s physical and virtual routing, switching, and security platforms. Junos OS improves network operations and increases service availability, performance, and security with features like low-latency multicast, comprehensive quality of service (QoS), unified in-service software upgrade (unified ISSU), and Junos Continuity, which eliminates the risk and complexity of OS upgrades. Junos OS comes with embedded scripting tools and APIs, which enable automation of many routine tasks and practical integration with any operator’s back-end management tools. With secure programming interfaces, the Juniper Extension Toolkit (JET), versatile scripting support, and integration with popular orchestration frameworks, Junos OS offers flexible options for DevOps-style management that can unlock more value from the network.
Management
Juniper Networks Junos Space Network Management Platform provides comprehensive management with broad fault, configuration, accounting, performance, and security management (FCAPS) capabilities for both device and service-level management. For device management, Junos Space supports Network Configuration Protocol (NETCONF), CLI, and SNMP v1/v2/v3, while its northbound APIs support easy integration with existing network management systems (NMS) and operations/business support systems (OSS/BSS). Running on the Junos Space platform, Junos Space Connectivity Services Director ensures effortless end-to-end service provisioning of Metro Ethernet (E-Line, E-LAN, E-Tree, E-Access), VPLS, L3VPN, Ethernet VPN (EVPN), and MPLS, using a simple interface to design, validate, and manage these services. Another application of Junos Space, Cross Provisioning Platform helps service providers provision E-Line, L2/L3 VPN services, and virtual private LAN service (VPLS) between Juniper devices and those from third-party vendors.
Features and Benefits
The ACX Series delivers new levels of programmability, reliability, and scalability to service provider and enterprise networks. The ACX Series portfolio improves customer satisfaction while lowering the total cost of operating, maintaining, and updating the network infrastructure.
Zero Touch Deployment
Based on Junos OS automation capabilities, ACX Series routers support a zero touch deployment (ZTD) feature that significantly reduces the time required to install and provision new equipment, resulting in lower OpEx, lower TCO, and greater operational efficiency. ZTD also reduces the complexity of deploying MPLS in the access layer.
Advanced Security Services
The ACX5000 line of routers enables advanced security services such as MACsec to protect against potential vulnerabilities in the network as well as subscriber traffic.
High Availability and Reliability
Junos Continuity and unified ISSU features eliminate the downtime risks associated with implementing new hardware or upgrading operating systems. Junos Continuity eliminates OS upgrades and system reboots when adding new hardware to ACX Series routers—a plug-in package provides the drivers and support files needed to bring the hardware online. Unified ISSU reduces the risks associated with OS upgrades by enabling upgrades between two different Junos OS releases (major or minor) with no control plane disruption and minimal traffic disruption on the forwarding plane.
MEF CE 2.0 Compliant
The ACX5000 line of routers are all Metro Ethernet Forum (MEF) CE 2.0-compliant and are able to support all carrier Ethernet services, including E-Line, E-LAN, E-Tree, and E-Access.
Full Feature Set of L2, L3, IP/MPLS
ACX Series routers support a full feature set of L2, L3, and IP/MPLS, enabling service providers to not only monetize Layer 2 Ethernet services, but also Layer 3, IP/IP-VPN, and other services.
The ACX5000 line of Universal Metro Routers adds operational intelligence to metro environments, giving you the option to deploy packet optical, Metro Ethernet, and IP/MPLS infrastructure. The ACX5000 platforms address multiple service provider use cases, including cable distributed access architectures, residential fiber (including Juniper Unified PON), and mobile backhaul, as well as enterprise applications for utilities, oil and gas, mining, transportation, defense, and public safety industries.
