Editor's Notes
- So how do you transform the campus and branch infrastructure to support cloud applications? Unfortunately today’s campuses are brittle and manual. Campus architectures are complex with: layers of switches and VLANs and, multiple management points that require different tools which adds to operational difficulty Add on security layers of every flavor from load balancers to security du jour products, and it’s every network administrator’s inherited nightmare! Any change to the network can break something or open a security gap making it difficult to rapidly deploy and troubleshoot applications.

Any change to the network can break something or open a security gap making it difficult to rapidly deploy and troubleshoot applications.
- So how do you transform you enterprise campus network? You need to adopt a simplified architecture to start building an agile network. The first step is to look at the lessons learned in the data center. Leveraging fabric technologies and simplifying management for automation of new network elements is key. [Click] Collapsing core, distribution and access into a single simple to manage platform from the DC or Campus headquarters removes operational headaches while providing functionality for more network agility. With a single, simple to manage platform, you can expand access port functionality, protect the edge via the cloud, and centralize configuration, provisioning, management, policy and visibility. And it works regardless of the deployment model: physical or virtual; public or private cloud; or traditional IT. [Click] For example, Junos Fusion Enterprise allows customers to build an agile enterprise network with plug and play technology allowing for access switches to look like extension ports of the core switch. It utilizes automated configurations to provide simplified operations and management.
- Junos Fusion Enterprise is simple, smart and flexible. By collapsing the entire network infrastructure into one logical device it: tremendously simplifies management, brings consistency to operations and ultimately helps you realize CAPEX and OPEX savings. Simple Junos Fusion Enterprise greatly simplifies daily operations and reduces time spent on adds, moves and changes. Enterprise Fusion supports plug-and-play expansion with zero touch provisioning for satellite devices. Simply have your Smart Hands team plug in the device and Enterprise Fusion does the rest. The new satellite device is auto discovered, with no IT intervention. Also, VLANs are auto-sensed and automatically provisioned on the correct ports. Junos Fusion Enterprise also features Rolling Software Upgrades. This allows network operators to stagger the software upgrades for all satellite devices. For example this allows operators to qualify new software before a full rollout by only upgrading designated test satellite devices and not all satellite devices. Ultimately you get flexibility that ensures the highest availability for apps. Network Director provides single point of management for Junos Fusion Fabric—it centralizes management and orchestration all from a single-pane-of-glass. With ND you manage all Fusion Enterprise devices, services, policies, access control and VLANs. ND also allows you to visualize your entire enterprise, both campus and data center topologies, and it allows you to analyze traffic flows and execute bulk operations. Simple to Secure – with Fusion Enterprise you can instantly deploy and update access policies throughout the entire network. Simply apply the policy once in the EX9200 aggregation device and Fusion Enterprise does the rest. Simplifying configuration and keeping the network consistent, Fusion Enterprise eliminates error-prone, box-by-box manual changes that can lead to opening security gaps. Ultimately you get greater visibility into the network for faster identification, location and isolation of threats and intruders. Smart Junos Fusion Enterprise is built the open standards-based 802.11BR protocol, using open application programming interfaces (APIs). It delivers a loosely coupled system that allows for distributed forwarding scale. Fusion Enterprise supports native L2, L3, MPLS and Ethernet VPN (EVPN), providing a bridge to software-defined cloud networking with no protocol or vendor lock-in. Our commitment to programmability and open APIs also gives customers the flexibility to leverage solutions from Juniper’s ecosystem partners. Fusion Enterprise is also highly resilient. Since it employs the EX9200 as the core, Aggregation Device, a Fusion Enterprise fabric inherits these resiliency features: Separate, dedicated data, control and management planes Master and backup routing engines that can run in active-active mode. They’re capable of supporting different Junos versions for maximum availability and separation The EX9200 features hot-swappable, field replaceable components including line cards, fans, power supplies and routing engines The EX9200 also features ISSU, In-service Software Upgrades, allowing for seamless upgrades with no traffic loss or performance degradation. Fusion Enterprise’s Rolling software upgrade feature allows network admins to stagger network upgrades. So for example, they can choose to upgrade floors 1-5 at 8am, floors 6-15 at noon, and floors 16-20 at midnight. This reduces risk and prevents the need to perform massive, disruptive rollbacks of the entire network, for example. As you may know, the EX9200 features the ability to program its control and management planes via open APIs. This allows it to support Junos OS-based automation with Junos SDK, enabling integration with Puppet or other automation apps or integration with orchestrating apps like OpenStack. The beauty of Fusion is that it allows the entire network to inherit any these programmability features. So now the satellite devices are effectively programmable and controllable by automation and orchestration applications. Flexible Junos Fusion Enterprise’s flexibility provides you with investment protection. Today you can deploy EX9200 core switches and EX4300 access switches in your enterprise network using Virtual Chassis technology and, with a simple software upgrade, transform it into a Fusion Enterprise fabric tomorrow. And you can simply incorporate the existing wiring and topology. For instance, if you have a 10 member EX4300 Virtual Chassis configuration, that group automatically becomes a Fusion Enterprise cluster, with no need to touch wiring. Essentially, Fusion Enterprise allows you to use the same hardware and topology of your current infrastructure. Also, your on premise data center can be incorporated in Enterprise Fusion. The EX4300 EX4300 ToR switches become Satellite Devices as you connect them directly to the EX9200 Aggregation device. Through its use of the EX9200, Fusion Enterprise now gives you connectivity support from 1 to 100 GbE. At the access you can choose from 100BASE-T to 40 GbE. In terms of wiring Fusion Enterprise gives you maximum flexibility with options such as dual-homed satellites to a single aggregation device or dual-homed via different satellite cluster members. Simple, Smart, Flexible The result? True business agility.
