Carrier Ethernet vs. MPLS for Critical Infrastructure Operational Networks

You certainly know that SONET/SDH is an aging technology and that if your operational network is still based on it then you will need to transition to a packet switched network. Just as certainly, you know that the Internet Protocol (IP) as used in IT networks defines packet formats and routing protocols, but does not define a full networking solution for OT networks. You have probably heard that Carrier Ethernet (CE) and Multiprotocol Label Switching (MPLS) are alternative solutions, but you may be unsure which is more suitable for operational networks.

THE USER’S VIEW OF THE 5G RAN

whitePaper | October 26, 2022

Obviously, RAN performance and user experience are correlated. Still, there are ways to optimize the RAN performance to maximize the user experience that go beyond the optimization of individual RAN parameters. By improving the user experience, the wireless infrastructure becomes more cost-efficient, and the operator can squeeze more out of its network for the same investment.

The Role of C-band in 5G

whitePaper | May 7, 2021

The C-band (or midband) is considered the “waterfront property” of RF spectrum for 5G. It offers the best compromise between RF coverage and RF bandwidth and Providers are investing heavily on C-band 5G deployment to deliver the coverage and capacity that 5G use cases need.

MOBILIZING PRIVATE 5G NETWORKS

whitePaper | May 13, 2021

This whitepaper from Cambridge Consultants has been written as a practical guide to the successful implementation of private 5G networks, maximizing ROI and creating competitive differentiation. The report has been written in response to the many enterprises who are exploring – and even starting to roll out – private 5G networks as spectrum is released around the world. The use cases these networks enable promise to deliver huge business advantage

Orange’s vision for 6G

whitePaper | February 28, 2023

With the ambition to prepare for the future, Orange is contributing to the design of the 6th generation of mobile communication, what we refer to as 6G. Orange is actively involved in several 6G collaborative research projects and leading initiatives, including the European flagship Hexa-X project [1], the NGMN Alliance [2], and the IOWN Global Forum [3]. Committed, as a trusted partner, to give everyone the keys to a responsible digital world, we think it is our role to provide inspiration and vision, as well as an informed explanation about this future technology currently in the making.

FROM UTILITY TO UTELCO

whitePaper | August 1, 2021

UTelcos are competitive telecom operators owned by or related to a utility company (power, water, gas, oil, transportation). They usually begin as a group within the utility company in charge of delivering internal communication services. They can then become a competitive telecom operator under the utility-holding company or government entity.

VMware NSX

whitePaper | January 10, 2022

VMware NSX® is the network virtualization and security platform that enables VMware’s cloud networking solution with a software-defined approach to networking that extends across data centers, clouds and application frameworks. With NSX, networking and security are brought closer to the application wherever it’s running, from virtual machines (VMs) to containers to physical servers. Like the operational model of VMs, networks can be provisioned and managed independent of underlying hardware.
