Internet-Scale Routing Platform 

The fixed form factor SLX 9740 router delivers high density 100G with either (2RU) 80 x 100 GbE or (1RU) 40 x 100 GbE portsIt is designed to cost-effectively deliver the scale and performance needed to address the explosive growth in network bandwidth, devices and services for ultra-high-end enterprise and service provider data centers and enable cross connections for Internet Exchange Points (IXPs).  

Both platforms are powered by Extreme SLX-OS that provides carrier-class advanced features, such as Extreme routing, Carrier-class MPLS, Carrier Ethernet, and VXLAN overlay technology and is deployed in the most demanding networks around the world. 

Ultra-Deep Buffers & Pervasive Visibility  

The border router is the interconnection point between internal networks and the internet. With more traffic moving across routers, there is added demand for capacity, the ability to absorb speed mismatches and handle microbursts without compromising performance. The SLX 9740 has ultra-deep buffers of up to 16GB along with intelligent algorithms to ensure optimal performance.  

The Extreme Integrated Application Hosting delivers a new approach to network monitoring and troubleshooting with a guest VM and an innovative 10 Gbps internal analytics path. This highly flexible capability enables required data to be extracted from the network, viewed directly via analytics tools on the Guest VM or stored and optimized on-device for cost-effective delivery off-device to cloud-scale management, operational intelligence, and automation systems for additional analysis, action, or archiving. By embedding network visibility on every border router, the Extreme SLX Integrated Application Hosting can help organizations achieve pervasive visibility throughout the network to quickly and efficiently identify problems, accelerate mean-time-to-resolution, and improve overall service levels. 

The following paragraphs summarize the ideal use cases for the SLX-9740: 

Core and Edge Internet Exchange Points (IXPs) 

With new record highs of data and more and more demand for fast Internet speeds at internet exchange points (IXPs), cost per port is a key consideration for customers looking to migrate from 10 GbE to 100 GbEUltrahigh-density ports with the right mix of technologies (e.g. VPLS and EVPN) provide significant savings in power and cooling costs. This allows peering at 100 GbE speeds from IXPs to their customers (Gaming, Content Cachinglarge Enterprise) as well as cloud providers (Google Cloud Platform, Amazon AWSMicrosoft Azure).

Flexible Border Routing Solution 

The SLX 9740 is the industry’s most powerful, compact, deep buffer, dual stack IPv4/IPv6 Internet border routerIt provides a cost-efficient high-density solution that is purpose-built for the most demanding service provider or large enterprise data centers.

Enterprise and Co-location data centers consolidate on multiple layers and the SLX 9740 can sit as an edge router above the data center network. With the use of MPLS or layer 3 protocols, the router can provide inter-data center connectivity as well as connectivity to Internet peersMulti-Chassis Trunking (MCT) provides dynamic, flow-based load balancing to multiple network nodes, enabling resilient and high-performance networks. Load balancing, band steering and many other attributes can all be automated.

Data Center Spine 

The SLX 9740 can function as a highdensity spine and can route out of the spine layer, thus collapsing the core and spine layers and eliminating for a border leaf.

To summarize, the following use cases are best supported: 

  • Core and Edge Internet Exchange Points (IXPs) 
  • Flexible Border Router with DCI 
  • Core Aggregation 
  • Date Center Spine
