Software-Defined Networking

 

Software-Defined Networking (SDN) is a network architecture approach that enables the network to be intelligently and centrally controlled, or ‘programmed,’ using software applications. This helps operators manage the entire network consistently and holistically, regardless of the underlying network technology.

Enterprises, carriers, and service providers are being surrounded by a number of competing forces. The monumental growth in multimedia content, the explosion of cloud computing, the impact of increasing mobile usage, and continuing business pressures to reduce costs while revenues remain flat are all converging to wreak havoc on traditional business models.

To keep pace, many of these players are turning to SDN technology to revolutionize network design and operations.

SDN enables the programming of network behavior in a centrally controlled manner through software applications using open APIs. By opening up traditionally closed network platforms and implementing a common SDN control layer, operators can manage the entire network and its devices consistently, regardless of the complexity of the underlying network technology.

network firewall

  The network firewall is the first line of defense for traffic that passes in and out of a network. The firewall examines traffic to ensure it meets the security requirements set by the organization, and unauthorized access attempts are blocked. Firewall protection has come a long way in recent years. In addition to monitoring internet traffic, the latest network firewall security products incorporate a wide range of additional features. “The latest firewalls can neutralize an attacker’s ability to use stolen credentials for lateral movement and network compromise,” said Navneet Singh, product marketing director at Palo Alto Networks. “This is done by enforcing multi-factor authentication at the network layer.” The intention behind network firewalls is that they filter internet transmissions so that only traffic that belongs is allowed into an organization. Decisions are based on pre-set rules or policies. Like many areas of technology, firewalls have evolved greatly over time

Commercial sales

  Given the current economic climate, the move towards online dissemination of information and the drive for open access and free information, commercial sales is becoming an increasingly attractive revenue-generating proposition for publishers. Unlike  most traditional advertising and sponsorships, the online medium offers much more variety and flexibility. It is possible to devise programs that help commercial partners with exposure, brand awareness, lead generation and education of the market in a non-intrusive way that can be welcomed by the audience as genuinely beneficial. Commercial sales’ describes the revenue that a publisher generates from sources other than content sales. The revenue normally comes from a commercial third party that has a target audience of the readership of a particular publisher’s content. The most traditional commercial sales take the form of advertising/sponsorship and the publishing of third party content under an existing brand. However, the trend
