IPv6 was initially specified in 1995 by IETF but only in 2012 it started to commercialize. Last year global adoption was below 50%. Looks like motivation of more addresses and enhanced security was not too compelling. This year we see the boost all over the world including Central Asia and specifically Uzbekistan. Thanks to joint efforts by Ministry of digital technologies and Operators IPv6 adoption in the country jumped x20 to 2023's numbers. As Operators reported on the 2nd IPv6 Summit during ICT week 2024 in Tashkent they were motivated by new technologies working over IPv6 (SRv6, 400GE, other) which proved economical benefits for the business.  Ministry, Unicon R&D, RIPE NCC and IPv6 Forum jointly released White Paper with recommendations on IPv6 promotion polices on gov level. Hope next year to see x100 boost in the country! All the best 👍 #ipv6 #srv6 #ipv6forum #ictweek https://lnkd.in/eDA9QigZ

Telecom towers, a word that 90% of people and even telecom engineers call cellular base stations, which serve mobile users. However, a communications engineer must be careful using these designations, especially when he is present at job interviews and meetings with specialists. 1-Towers with antennas for mobile phone service, they are called mobile coverage towers (cellular network towers) 2-The towers carry microwave antennas (Microwave Antenna). 3-The towers carry antennas to serve Tetra (TETRA) communications. 4-There are also stations and communication towers dedicated to satellite communication💙💙

Answering the question "What must I do to be Saved!" Starts with: 1. Acknowledge you are a Sinner in need of a Savior -simply, a broken relationship with God and Humans with its consequences. 2. Believe in Jesus as the Son of God and that he died and resurrected to save you from your sin 3. Ask Jesus to be your savior and the Lord over your life 4. Repent, Turn a new leaf and Follow Jesus and he will lead you into a victorious life Its all about Jesus 😊 Paul's writing to those in Rome - Romans Chapter 10: 9 If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved.  10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. Best part is - Its available to all of us (Everyone) regardless of race, title or location. We are made in God's likeness, given various gifts and talents, and we are loved by him. for all of us: 13 for, “Everyone who calls on the name of the Lord will be saved.” to think further: Will the consequences of Sin be our persuasion ? or Will restored relationships. Will guilt and trouble ? or Will the joy of fullness of Life both Present and to come.

It utilizes 5G's infrastructure. It provides superior call quality. It eliminates the need for 4G fallbacks. VoNR call flow involves following steps. 1. Call Initiation 2. RRC Connection Request 3. RRC Connection Setup 4. NAS Registration Request 5. NAS Registration Accept 6. PDU Session Request 7. PDU Session Accept 8. SIP INVITE 9. Alerting 10. Call Answer 11. Call Confirmation 12. Call Continuation 13. Call Termination These are mainly for Standalone deployment. Other deployments involve different steps. VoNR might seem complex, but its benefits are clear. Let me know your thoughts on VoNR. Thanks for reading. If you find this informative, then repost. Share it with your connections. 🙏

I will be presenting two sessions at the Cisco Automation Developer Days: 1- "Managing the Managers: Optimizing Network Performance with Cisco NSO and OpenTelemetry". In this session I will discuss how to leverage APM tooling ecosystem to manage your network automation toolchain. I will also demo our furst implemention of the latest IETF Context traces drafts in Cisco NSO. 2- "NETCONF, RESTCONF, gNMI, OpenConfig What to Chose?", many of you are ready to leave CLI behind but several options are available to you. In this session I will just lay down the status of the industry, trying to help you to take the right decision for your environment. I will also demo how NSO can manage a mix NETCONF/gNMI/Native/OpenConfig environment. Most importantly, I am looking forward to meet with developer teams from my customers and discuss and receive their feedback.

!!Next step achieved in Network automation for enabling network models&templates!! I've already written about our Network Automation strategy for Public Cloud based in a SDK with all generic network elements to abstract new developments from the specific technology of each Cloud provider and enabling useful getters, setters and decorators. Now we are not limited to check if the routing is correct, coherent and symmetric in Microsoft Azure, but also check if it is also enabled in network security groups (NSGs)/Azure Firewall rules and to be able to configure it. So that means that you can enter a network modelling traffic patterns for certain communications requested by users and enable them, provisioning any network rule if it is needed o it is a very big achievement that can save a lot of time for operational groups and avoid human errors. !!Next Step, to be MultiCloud!! which is something achievable as the code is vendor agnostic and we just only need to adapt modules to how it is done specifically in AWS, Google Cloud, OCI.... or whatever Cloud Provider. There are already commercial tools to be able to do this with OnPrem networks, but I don't think this happens with Public Cloud, so maybe next-next step is to offer a product and start becoming technology sellers??

In recent couple of months I frequently got asked what is the relation of DT’s T-CaaS and Linux Foundation Europe’s Project Sylva. Lately, the same topic was addressed by Iain Morris of Light Reading: https://lnkd.in/efbNwNVD. T-CaaS is exactly that DT’s horisontal infrastructure layer for CNFs in practice. It is since more than 3 years a single platform for all CNFs that we are deploying. As it precees Sylva in time, it is naturally not the same thing. The large deployed base spans several hundreds of existing clusters that host many CNFs. It is someting that does not change on its own over night. Luckily, it is based on same philosophy (like upstream #Kubernetes first, #GitOps), technologies & components (like #CAPI, #FluxCD, #metal3…) like Sylva. I have also recently briefly highlighted value of community approach and our homework in that regards (see the very end of closing remarks in this presentation: https://lnkd.in/eg7dYAGp) In slight difference to what Laurent Leboucher mentioned with regards to platform approach of telco vendors, I would rather very much welcome Ericsson delivering their own platform based on hardened upstream Sylva stack as well as contributing to it, instead of choosing 3rd party commercial #k8s solution like Nokia. Btw. working many years ago in a very small #CSP I see argument by Ericsson, that many small and medium operators ask for infra+CNF bundle, credible. Sometimes there are pure single vendor deployments of all NFs in one CSP. In that case vendor bringing horisontal infra layer makes a lot of sense. But based on community/upstream stack please.

I like this short video that emphasises the power of automation to deploy a Private 5G network when the network functions are containerised (aka CNFs). Automation is a broad topic and can take different shapes and forms like the use of OpenShift Operators for deploying and configuring SR-IOV for performance optimisation or PTP for synchronisation but also using GitOps to support a ZTP (Zero-Touch Provisioning) approach. A cloud platform like Red Hat OpenShift is leveraging automation at every layer even RHEL CoreOS, the container specific OS is managed by the platform through a MachineConfig Operator. I just miss in this video more details on which part of the automation is done by Ansible Automation Platform. Hopefully for this we have System Integrators partners such as Odine who could explain you how they did use Ansible for supporting customers like Turkcell for deploying 5G (not private 5G in this case) at scale: https://lnkd.in/evTKarW5 In a Telco Cloud, it is not only about one automation technology but a set of automation enablers that must be used in concert to deploy, manage and secure the clusters and the workloads that support the network evolution. Extra reading: If you want to better understand what is an Operator: https://lnkd.in/ehy_m6aK #automation #openshift #operators #GitOps #ZTP #ansible #private5G #telcocloud
