It is not easy to settle the debate for DPDK vs SR-IOV-the technologies used to optimize packet processing in NFV servers. For one, you will find supporters on both sides with their claims and arguments. However although both are used to increase the packet processing performance in servers, the decision on which one is better […]
Feeling confused about the role of SDN in NFV? You are not alone!.. Many get stuck in understanding the role of SDN in NFV. Still, others want to know what is SDN ? And Others simply are not clear about the use cases for SDN in NFV. Do you know that without the right SDN architecture, you […]
Having knowledge about NFV without understanding how Network Services/ VNF Forwarding Graphs are created, is like owning a car without knowing how to drive it. “Network Service” (NS) holds importance in NFV as in the majority of cases, VNFs connect with one another to create services instead of working alone. Also, VNFs connect to create […]
Think about NFV! Think about x86 processor ….Both of them are inseparable. Isn’t it? No matter how simple a processor (compute part) sounds, I bet a lot of people don’t know that the compute domain in NFV is not just the compute processor of the node…Actually it is much more. The fact is that the […]
SD-WAN is designed for the worst medium. We depend on the internet and broadband for out WAN . And you know that quality on the internet is not guaranteed. However, SD-WAN vendors have found some solution:
NETCONF/YANG vs TOSCA for NFV service orchestration is more of an academic discussion rather than a practical one. To many, there is a misunderstanding on the exact place where TOSCA should be used vs NETCONF/YANG. Trying to use one tool to do the other’s job is like fitting a square peg in round hole. Remove […]
Thinking of implementing SDN in your MPLS WAN ? without a forklift ? Look no further ! as BGP-LS ( BGP-Link State) and PCE ( Path computation Element) give a right combination. In this Blog, I talk about an evolutionary ( not the revolutionary approach) to SDN in WAN. SDN-based MPLS network, running PCE and […]
The emerging Docker containers have potential to revolutionalize NFV. After all, they are lightweight compared to virtual machines; they need less overhead and resources; and, they can provide application isolation running in the same operating system, they live in. That means, if a Virtual Network function (VNF) in NFV can run in a Docker container […]
