Why the Network Will Drive the Next Wave of Mobility
Forty years ago, the first phone call was placed on a handheld mobile phone. The call was placed by Martin Cooper at Motorola’s Communications Systems Division, who phoned a competitor at Bell Labs—and launched a new era. The brick-like prototype he used weighed two pounds and cost nearly $4,000.
Reflecting on the first mobile phone call also gives us a great opportunity to think about where mobile communication will take us in the years to come. In a few short decades, cell phones have evolved from a clunky appliance used mainly by high-powered businesspeople, into a key part of everyday life. Read More »

Much has been made of the emergence of Software Defined Networking and the programmable network. At its core, SDN involves opening up network interfaces in order to make the network programmable and allow for the development of applications. While some of those applications interact directly with the data plane, determining how individual packets are treated, many applications actually involve what can fundamentally be described as management functionality – automation of workflows, reaction to events, closing of control loops. A popular example concerns orchestration, in which resources are allocated and state modified so that collectively a service is provided – in many ways resembling a reincarnation of service provisioning in a new context and under a new name.
Of course, management applications and management interfaces have been around for a long time, so what is really new and different this time? Is SDN simply an exciting new label for a tired old concept? Does SDN obviate the need for traditional management? At the core of these questions are the concepts of programmability and manageability. Read More »

On March 19th, 2013 Cisco announced the best 2-socket virtualized SAP Sales and Distribution (SD) Benchmark result in a Linux environment with the Cisco Unified Computing System™ (Cisco UCS®) delivering high scalability and low latency in virtualized SAP Business Suite deployments.
Cisco’s benchmark result for the Cisco UCS B200 M3 Blade Server show support for up to 5530 concurrent users and a SAP Application Performance Standard (SAPS) score of 30,270 derived from the processing of 605,330 order line items per hour and 1,816,000 dialog steps per hour. This result demonstrates that a Cisco UCS B200 M3 Blade Server configured with a LSI 400-GB SLC WarpDrive can deliver high scalability and low latency in virtualized SAP Business Suite deployments.
The tested configuration consisted of a Cisco UCS chassis equipped with one Cisco UCS B200 M3 Blade Server running Red Hat Enterprise Linux (RHEL) 6.4 on KVM. The server was configured with two 2.90-GHz, 8-core Intel Xeon processor E5-2690 CPUs and 256 GB of 1600-MHz memory. The blade server ran both the SAP Business Suite application software and the 64-bit Sybase ASE 15.7 in a single virtual machine. SAP Enhancement Package 5 for SAP Enterprise Resource Planning (ERP) 6.0 was used in this scenario. The Cisco UCS B200 M3 Blade Server recorded the best two-way virtualized SAP SD Benchmark result on SAP Enhancement Package 5 for SAP ERP 6.0 and Sybase ASE 15.7. In the test, 5530 SAP SD Benchmark users were supported while a consistent application response of less than one second was maintained.
The “Cisco UCS B200 M3 Blade Server: High Performance and Flexibility for Virtualized SAP Business Suite Deployment” Performance Brief provides additional benchmark configuration details.Official Benchmark Certification is available at the SAP® Standard Application Benchmarks certification web site.
Many business organizations currently struggle with the cost of maintaining RISC processor–based servers running proprietary operating systems and third-party database management systems. Cisco UCS enables organizations to use lower-cost industry-standard x86-architecture servers, open source operating systems, database management systems, and allows organizations to run SAP Business Suite applications in virtualized environments. With Cisco UCS, organizations can easily balance workloads across a pool of servers to manage service levels according to business priorities, scale environments up and down as needed, and contain costs by consolidating workloads onto a smaller number of servers.
Using the Cisco UCS, IT departments can run virtualized SAP Business Suite applications with the flexibility, scalability, and lower cost of virtualized environments. These innovations delivering high scalability and low latency in virtualized SAP Business Suite deployments and the dramatic reduction in the number of physical components required illustrates the value created by Cisco UCS solution for customers planning migration away from proprietary RISC/Unix based systems to open source operating system software and standards-based computing infrastructure.

We’ve been actively promoting the adoption of IPv6 at various venues – back in January at Cisco Live London, and a few weeks ago at the V6 World Congress, which focused on the adoption of IPv6 in mobile networks.
Our next big venue is Cisco Live in Orlando, Florida June 23-27, 2013 and I want to take the opportunity to reflect on how IPv6 is becoming an increasingly important component of the event agenda, infrastructure and look forward to some of our future ideas for Orlando.
I have personally participated in Cisco Live for over 15 years as a speaker but this was my first time as a member of the IPv6 Team. For those of you who do now know I am the Product Manager for IPv6 in Cisco’s Core Technology team that we call Network Operating Systems Technology Group.
My observations on what I saw and heard in London were as follows: Read More »

Dan Goodin, editor at Ars Technica, has been tracking and compiling info on an elusive series of website compromises that could be impacting tens of thousands of otherwise perfectly legitimate sites. While various researchers have reported various segments of the attacks, until Dan’s article, no one had connected the dots and linked them all together.
Dubbed “Darkleech,” thousands of Web servers across the globe running Apache 2.2.2 and above are infected with an SSHD backdoor that allows remote attackers to upload and configure malicious Apache modules. These modules are then used to turn hosted sites into attack sites, dynamically injecting iframes in real-time, only at the moment of visit.
Because the iframes are dynamically injected only when the pages are accessed, this makes discovery and remediation particularly difficult. Further, the attackers employ a sophisticated array of conditional criteria to avoid detection:
- Checking IP addresses and blacklisting security researchers, site owners, and the compromised hosting providers;
- Checking User Agents to target specific operating systems (to date, Windows systems);
- Blacklisting search engine spiders;
- Checking cookies to “wait list” recent visitors;
- Checking referrer URLs to ensure visitor is coming in via valid search engine results. Read More »
