Is Edge computing the only hope for service providers? With billions spent on cellular networks, everyone asks about the killer use cases for 5G. The new 5G Core is capable to provide ultra-low latency services opening the network to potential new user cases, but it can not solve on issue-The distance and latency. However, this […]
Software-defined Data Center is no longer a “marketing term” as many would make you believe. Rather, it is a complete framework for building your next software-based data center backed by standards. So it is important to understand a Software-defined data center ( SDDC)! But that’s not the only reason. The other reason is the confusion […]
The “Overlay vs underlay” discussion is important as overlays are everywhere in networks- in the Datacenters (DCs) and in SD-WAN. And there are many tutorials out there explaining overlays and in particular difference between overlay and underlay. However, they are difficult to understand, and more importantly, they do not address the most important point – […]
So you want to know about 5G latency? And you know that the minimum latency needed for 5G is 1 ms or less. What if I tell you that you may be completely misunderstanding how this latency works in “5G” For example, tell me the following. Is the latency from the cellphone to the core? […]
Looking for Open RAN tutorial ? What is Open RAN/O-RAN and why it matters for mobile operators and vendors? In fact, as wireless networks continue to grow, O-RAN is becoming more relevant for Mobile networks. For one, disaggregation of RAN has remained non-existent. Thanks to a few big vendors’ monopoly. The RAN has been largely […]
OK, you have heard enough of these terms perhaps from RAN vendors? C-RAN vs Cloud RAN vs vRAN vs O-RAN in the context of Radio Access Network ( RAN) However, these terms are not clear to you because everyone out there explains them in a way that is enough to confuse many. The fact is […]
What is SASE or Secure Access Service Edge ? Is it SD-WAN? Is it something related to security? Everyone talks about SASE, very few are clear on the concept and its positioning versus SD-WAN and Security. The jargon out there in the literature is enough to confuse many. I will try to make it easy […]
Let’s face it, we all love to have everything cloud native based including cloud Native VNFs. In practice, however, we need to live with the legacy VNFs. The legacy VNFs are monolithic with bulky code and operated in some cases as all in one virtual machine. They can be called virtual, but not cloud-based or […]
