This will probably date me, but when I started in telecommunications a few years back, 10-Mbps thin-net Ethernet was the cool new technology. I used to think, “Who would ever need that much bandwidth?” Since then, IT technology has changed dramatically, with applications continually demanding more and more bandwidth. Ethernet switching capacity has advanced by leaps and bounds to keep pace with demand, ratcheting up connectivity speeds from 10 Mbps to 100 Gbps. For most data centers today, 1- and 10-Gbps connectivity is commonplace. But now 100 Gbps is quickly gaining traction in the vertical markets that require the highest performance. If history is any indication, 100 Gbps will be commonplace in most data centers in the not too distant future.
To meet the high-performance demands of today’s service providers, research labs, and large enterprises, Cisco started shipping a 12-port 100-Gbps module for the Cisco Nexus® 7700 platform switches about a year ago.
Nexus 7700 100G, 12 port module
The module is based on the Cisco® F3 chip, which offers the industry’s most comprehensive data center feature set for the core and the data center interconnect, including multicast, Multiprotocol Label Switching (MPLS), Virtual Extensible LAN (VXLAN), Cisco Overlay Transport Virtualization (OTV), and Cisco Locator/ID Separation Protocol (LISP). The module was designed to deliver line-rate performance with a total switching capacity of 1.2 terabits per second (Tbps). So, theoretically, a fully loaded Cisco Nexus 7700 18-Slot Switch chassis with 192 100-Gbps ports could deliver up to 38 Tbps of bidirectional throughput. No matter how you slice and dice it, that’s a lot of throughput—enough to meet the demands of any network.
As a matter of fact, 192 100-Gbps ports with 38-Tbps throughput would make the Cisco Nexus 7700 18-Slot Switch the industry’s highest-density 100-Gbps switch, with the Industry’s highest throughput rate. To verify this industry leadership, we put the switch to the test.
Cisco commissioned Miercom to conduct an independent performance test on a fully loaded Cisco Nexus 7700 18-Slot Switch with 192 100-Gbps ports. One of the first challenges Miercom faced was how to generate 38 Tbps of traffic to test line-rate performance. Miercom called upon Ixia’s world-renowned labs to help. The solution called for multiple Ixia Xcellon modules in Ixia’s iSimCity lab to conduct the tests (Figure 2).

Along with the raw throughput testing, Miercom also tested critical Cisco Nexus 7700 platform features to see how they would perform under full load. Tested features included MPLS, IPv4/IPv6 multicast, and hitless In Service Software Upgrade (ISSU).
After the testing was complete, the Cisco Nexus 7700 18-Slot Switch proved that it offers the industry’s highest 100-Gbps density and performance with line-rate services and exceptional availability. This level of scale provides customers with many years of investment protection as they transition from 1 and 10 Gigabit Ethernet to 40 and 100 Gigabit Ethernet architectures in the future.
Robert Smithers, CEO of Miercom, summed up the test results nicely: “Miercom independently exercised and evaluated Cisco Systems Nexus 7718 and was frankly stunned by the incredible power and throughput of this system, coupled with consistent low latency and latency variation, as well as solid MPLS support and high-availability features. The first switch we have independently tested with 192 x 100GE ports, the Cisco Nexus 7718 is awarded Miercom Performance Verified in our ongoing Data-Center-Class 100GE Switch Study.”
For the full details of the test, check out the comprehensive Miercom test report and accompanying test/results video. Also, here is what Miercom and Ixia had to say in their press releases.
Here’s a quick summary of the Miercom test results:
- Testing found the Cisco Nexus 7718 can forward at line rate on all 192 of its 100GE ports – delivering over 38 Terabits/s of bidirectional traffic
- Testing confirmed the Cisco 7718 can distribute real-world IPv4 and IPv6 multicast traffic at wire speed, with each of 191 receiver ports handling 1,250 IGMPv2 groups
- The Cisco 7718 can process real-world MPLS traffic at line rate on all 192 of its 100GE ports, with no loss and low latency
- Testing confirmed that an active Supervisor module or fabric module can be replaced with no packet loss, with IPv4 and v6 traffic running at high capacity on all of its 100GE ports
- The Cisco 7718 executed an in-service software upgrade, with IPv4 and v6 traffic running at high capacity on all 192 of its 100GE ports, with no loss

This is part 1 of the “Your Business Powered By Cisco Customer Solutions Architecture (CSA)” blog series.
Many IT organizations are challenged to take advantage of the new technologies enabled by Virtualization, Cloud, Analytics and IoT. Applications enabled by these new technologies must be protected from unauthorized use but remain accessible, in a secure manner, from any device in any location throughout the world. With a vast array of new technology choices and a substantial installed infrastructure base, it is important to have a place to start --a solutions architecture-- that provides a framework for using these technologies that will drive business outcomes.
The CSA is a transformational customer-facing blueprint that delivers IT-based services for enterprise and service providers to achieve their business outcomes. To be relevant for our customers, the CSA was developed based on disruptive examples that Cisco engineers observed in the industry during their discussions with both enterprise and service provider customers worldwide.
Some of these disruptive examples include use of new technologies such as: Analytics, Cloud, Internet of Things (IoT), Internet of Everything (IoE) and Cyber security. It should also be stated that the front end for IT blueprint consulting is Cisco Consulting Services, and this CSA is representational of the sets of abstractions that describe the actual functions.
In all IT environments, both enterprise and service providers, Cisco sees two common trends: Read More »

What kind of a world will you live in three years from now? How about five? Will your personal robot pour you a drink after your self-driving car delivers you home? That’s where we’re headed, and it’s a pretty quick trip: self-driving cars are already on public roads and you’ll soon be able to buy that humanoid robot.
Cisco’s Collaboration team thinks a lot about the future—not just about how we’ll get around and get our drinks, but about how we’ll connect and collaborate. We’re passionate about the future of collaboration, about giving the world collaboration tools that are every bit as smart as those self-driving cars and whiskey-pouring robots.
Where we’re at: today’s challenges
Before we talk more about the future, let’s talk about where the industry is right now. Over the years, various vendors have given us audio conferencing, web conferencing, and video conferencing. Each of these technologies were introduced at different times, and have matured at different paces—with audio being the tried-and-true veteran, video conferencing the relative newcomer and web being the thing that came somewhere in-between.
Herein lies the problem: Read More »
