What is SDN? Where networks and network traffic were once managed using hardware appliances, modern network management can now be handled through virtual data centers using software management tools which allow for increased agility and flexibility.
There are many reasons why you might need to migrate to a newer, faster network, such as the need to reduce costs, upgrade from obsolete hardware, or the need for more bandwidth. Where there was once a time when 1Gb was considered the standard for cutting edge networks, today's IT managers and network administrators have their eyes set on the 100Gb network challenge.
Do you need a Network Packet Broker? Before you can decide whether you need one or not, let's remember what a NPB is…
Network visibility is becoming increasingly important as organizations are challenged to deploy increasingly complex network services, such as security, performance management and monitoring on an ever evolving and expanding network and data center architecture.
Improved efficiency of security tools In the first part of this blog series, we looked at how 100GbE-based Network Packet Brokers (NPBs) can help establish resilient connectivity between 10/40GbE-capable network security tools and 100GbE core networks. In this post, we will look at how NPBs optimize distribution of traffic from 100GbE networks to lower speed appliance ...
Once again, Cisco Live US lived up to the hype. People came from every part the world to enjoy the largest networking conference of North America! Last year, there were over 30k attendees, and this year it sure seemed like the crowd grew tremendously! For a 2nd year in-a-row, the show took place in the Mandalay Bay Convention Center in Las Vegas, Nevada. Attendees were enjoying themselves all around the city, especially on the night of the Bruno Mar...
The importance of having complete network visibility today can’t be overstated. If an organization can’t see into its network infrastructure, the consequences can be detrimental. With comprehensive network visibility, enterprises and service providers can identify and address network outages, enhance security, and deal with potential regulatory compliance issues—before there’s any negative impact on the business. But fo...
Organizations across the world are still continuing to come to terms with last week’s massive “WannaCry” ransomware attack, which crippled IT infrastructure on an unprecedented scale. In this post, we examine the nature and impact of this threat and why it requires pervasive and advanced network visibility for dynamic threat detection and remediation.
As communication networks — the internet in particular — continue to evolve, enterprises must adopt new and efficient technologies, such as cloud computing and virtualization, to improve their networks’ monitoring, security, and overall network visibility.
Enabling Non-disruptive, Resilient Threat Monitoring Enterprise data centers are experiencing tremendous growth in network traffic, as consumption of applications and content continues to rise rapidly in the information era. In addition, the widespread adoption of server virtualization is changing the direction of data center network traffic flows from the North/South flow of client-server applications to the East/West of server-to-server traffic. These dynamics require the da...
