Today’s reliance on the cloud extends beyond increased efficiency and agility into reduced power reliance and response to the unexpected. Innovative companies like NTT DATA, which we’re spending time with today, have transformed their business even during adverse conditions. The global data company was able to reorganize its platforms to slash TCO and achieve greater energy efficiency. By consolidating servers, NTT DATA reduced carbon emissions by 3,450 tons over just five years and actualized these benefits further for customers like Japan Radio Co. by combining private cloud with Cisco Unified Computing System (UCS). How will your business recognize these same cloud benefits? View the Read More »
With the rapid depletion of IPv4 addresses, migrating to IPv6 is no longer an option for many organizations. Part of the challenge operators face is that both IPv4 and IPv6 addresses will be used within the same network. In addition, individual devices will often have both types of addresses, making it more difficult to accurately view the current network topology.
Having to manage both IPv4 and IPv6 addresses increases the complexity of every task associated with IPv4 resources. When addresses are managed manually, operators have to first look up a resource’s IPv4 address and then configure the IPv6 address by hand. Operators then have to set up the address on the DHCP server as well. This simple operation takes several steps and involves inputting the same data into the system multiple times. Given that IPv6 addresses are four times longer than IPv4 addresses, this increases Read More »
Efficient management of network elements requires that operators track the IP addresses assigned to each device when they are attached to the network. When discovery is managed manually, an operator may forget to email a confirmation or perform one of the crucial steps in the provisioning process. Rather than requiring operators to perform these steps manually, the management system can automatically assign and record IP addresses as well as send any confirmations. In addition, the system can receive commands and trigger flows back downstream to further automate processes and simplify the workflow.
Cisco Prime Network Registrar, for example, offers a broad scope of IP address management (IPAM) capabilities for automating discovery. IP addresses for new devices are immediately added to the network’s IP inventory, guaranteeing that they will not be overlooked or mistyped.
Cisco Prime Network Registrar also locates and identifies unknown devices on the network, including smartphones, routers, and printers users have provisioned themselves. When an IP address is used without being formally allocated, this creates a potential conflict with mission-critical equipment that could result in network downtime that is difficult and time-consuming to troubleshoot. Operators can either remove these rogue devices from the network or formally discover them to shore up potential security vulnerabilities that might otherwise pass undetected.
The accuracy of the IP address inventory is maintained by refreshing it at regular intervals to ensure it still correlates to the ever-changing configuration of the network. Maintaining an accurate inventory of IP addresses is critical to reliable network operation. For example, by Read More »
Wi-Fi has truly come of age as a viable means to connect mobile devices to the Internet. The past four blogs in this series have highlighted some of the key findings of a recent survey of U.S. mobile users by Cisco’s Internet Business Solutions Group (IBSG). Our survey uncovered some startling revelations about what consumers are doing on their mobile devices, how and where they are using them, and how they are connecting them to the Internet.
The majority of devices are now Wi-Fi-enabled, and the fastest-growing category is “nomadic” devices such as tablets and eReaders. We now need to speak of the “mobile home,” as the home is by far the most popular location for consumers to use their mobile devices. Surprisingly, Wi-Fi is the network connection of choice for most consumers for all of their devices, but they would like to see Wi-Fi more seamlessly integrated with mobile networks. When they are not at home, mobile users are increasingly expecting public hotspots to provide Wi-Fi connectivity to these devices. While service providers are beginning to realize that they need to deploy Wi-Fi networks, our research clearly shows that there are viable monetization opportunities in mobile data off-load, customer retention, and new and innovative business models.
While it is never easy to foresee the future, here are five predictions for key changes in the mobile industry over the next two years as an outcome of the Cisco IBSG research: Read More »
During my recent visit to London, while at the Cisco House — way up on its perch above the Westfield Stratford City shopping centre, I had the opportunity to look out across the huge Olympic Park in amazement. It’s an experience that I’ll never forget — for as long as I live.
Most visitors to the Olympic Park will immediately notice the cluster of majestic sports arenas and a plethora of newly planted landscaping. Besides the obvious, there’s the potential for it to become so much more. This community regeneration project could be the basis for a socioeconomic metamorphosis in East London – a very welcomed new beginning.
