Virtualization has massively evolved cloud computing and computer networking, with VNF’s now available and sufficient for many network functions previously performed through dedicated hardware. Yet even today, achieving the near real-time performance expected of networking hardware is a still challenge for virtualized network functions typically running on open compute x86-based network hardware. Firewalls and intrusion …
The evolution of emergency services is now spearheaded by this year’s deployment of a nation-wide public-safety dedicated network known as FirstNet. This critical network reserves 20Mhz out of the valuable 700 Mhz frequency range due to the obstacle penetrating power this frequency affords. FirstNet was developed to provide mission critical communications and emergency services the …
We all agree that the tools and techniques of malicious online hackers have evolved and advanced alongside the technologies that enable them, making it essential that network administrators ensure their networks are prepared for any eventuality. This is where Network Behavior Anomaly Detection (NBAD) systems come into the picture. In this post, we will review …
Network computing infrastructure has been expanding for decades, and the network edge is no exception. When it comes to the expanding network edge, density is key; that’s why Intel’s Xeon D SoC processors have been steadily gaining favor. Servers, hot storage(instant access data- ie profile images) and network appliances(firewalls, access points) are being given more …
All the ongoing effort towards NFV/SDN in the telecom and networking world is really starting to pay off, as companies can now easily deploy working software-defined WAN solutions using inexpensive ISP’s bandwidth coupled with industry standard x86 rackmount network appliances. SD-WAN solutions offer incredible benefits outside of the immediate savings in CAPEX, like exponentially faster …
One major starting point for CSPs and ISP’s NFV solutions is the deployment of virtual CPE (consumer premise equipment), specifically the business oriented variation vE-CPE – Virtual enterprise CPE. The immediate benefits in reduced CapEx and flexibility make growing enterprise networks one of the first to receive NFV solutions in the form of vCPE from …
It’s becoming harder for traditional network equipment vendors to compete with the freedom, low CAPEX and sheer flexibility that software-defined networks bring to the table. Proprietary hardware-based solutions from vendors are continuously losing out to open source software solutions deployed on top of much cheaper, open hardware like x86 network rackmount appliances. Linux, the largest …
