This article focuses on challenges related to common information models, VNF performance monitoring, benchmarking; analysis and tools. We will also discuss about evaluation & selection of VNF lifecycle management vendor of NFV environment and use of Virtual Probe (vProbe) function for NFVi monitoring.
This article explains how FPGAs can be useful in network functions virtualization (NFV) platform to achieve better performance and flexibility. FPGAs are used to speed up processing of network packets for variety of network functions/ applications like Intrusion detection, firewall, packet parsing, content based
This article is focused on basics of VNFs: what are virtual network functions (VNFs), architecture of virtual network functions (VNFs), what are the basic components (VNFC and VNF Descriptors (VNFD)), challenges with current VNF development and onboarding to NFV environment and how cloud native VNFs can help overcome the challenges.
Software Defined Networking (SDN) and Network Function Virtualization (NFV) are vital technology innovations invented in last few years. Both of these technologies are collectively revolutionizing the current IT and telecom network infrastructure by enabling telco operators to make use of virtual machines in place of network equipment and further program the
First question that comes to mind is whether SDN and NFV are same or different or related technologies? SDN and NFV are independent technologies. SDN creates a separate management plane which sits a floor above the traditional control plane so as to get wider view of the network and orchestrate using network protocols like OpenFlow. So, with the SDN approach
2017 looks to be a promising year for software-defined networking (SDN) enthusiasts. According to recent research by IDC, the worldwide SDN market is expected to grow to $12.5 billion by 2020. This includes physical network infrastructure, control software, SDN applications, and last but not least professional services. Software-defined networking gained
OpenDaylight Summit, a flagship event of technology, is just few days away and it’s been held in Meydenbauer Center, Seattle. This year OpenDaylight have more than 40 sessions, keynotes, tutorials, speakers, etc., which will talk about various topics under the roof of open networking. The major topics which
The success of server virtualization is infectious. This prompted a search for a similar technological advancement in the networking industry. There was a need to replicate the model of how server virtualization reduced the cost of running isolated applications & improved agility. NFV or Network
Before we move ahead let’s get an understanding about Network Function Virtualization (NFV). What is Network Function Virtualization (NFV)?A basic definition of Network Functions Virtualization (NFV) states that it is a type of network architecture that virtualizes different network node functions into building blocks which may
Storage can be costly and inflexible. Enterprise storage devices with high performance and availability are very expensive portions of infrastructure in data centers. They are also quite inflexible as organizations need to purchase sufficient storage to meet ultimate storage requirements, whether for a year or a day....
