AT&T, BT and Qwest Communications International agreed to take a shot at our RFI. Masergy and MCI declined, while BellSouth, Broadwing Communications, CSC, EDS, Equant, Global Crossing, Level 3 Communications and Netifice Communications didn't respond.
Why MPLS
Amr Ahmed, internetworking practice director at Greenwich Technology Partners who has spent years immersed in MPLS, helped us analyze this RFI. Ahmed points out that frame relay is a circuit paradigm and MPLS a services paradigm: If you use MPLS to re-create your frame relay connections, you probably won't save much and may even pay more, given the price wars swirling around frame relay. Rather, MPLS' value stems from the integration of services, like voice, video and Internet connectivity.
Network slicing could be the answer to 5G rollout – but it's not easy to implement. Automation provides a way forward.
Wi-Fi 7 products, due out in 2024, will offer significantly more performance for enterprise users and can support more users in denser environments compared to Wi-Fi 6.
6G will leverage many different bands and tools to meet the ever-growing demands and expectations for cellular communications.
