In microwave communications—as in all electronic communications mediums—operators trend toward the latest technologies (e.g., IP/MPLS). They all have conditioning to think that newer is better. And by and large that’s right.
However, when it comes to IP/MPLS—one of the most advanced packet technologies—you need to handle this concept with care. Especially in a mixed infrastructure that includes microwave, fiber and other potential backhaul transport.
E-Band Global Regulation Roundup

Because of need for higher capacities, the trend toward shorter link distances for mobile backhaul and declining product costs, 70/80GHz (i.e., E-band) solutions are gathering significant interest for mobile backhaul and enterprise access applications. However, because these frequencies are new to most people, there is little understanding of costs and other issues related to licensing the 70-80GHz spectrum.

As symbolized at the recent EANTC interoperability testing event, Aviat microwave radios can help solve the complexity and scalability problems of Carrier Ethernet technology.
Carrier Ethernet (CE) transport networks are growing in both scale and complexity, requiring both vendors and operators to deliver solutions to sustain their growth. To help address this, Aviat Networks recently participated in the European Advanced Networking Testing Center’s (EANTC) annual multi-vendor interoperability testing event to validate several aspects of scaling CE networks, among other things.
Increasing CE network sizes increase the complexity of management—especially from a services perspective—when CE services span multiple network domains. The ability to partition management domains and effectively manage alarms that accurately identify and propagate notification of network faults, dramatically speeds up the fault isolation and resolution process across large networks. Utilizing and effectively implementing “Hierarchical Service OAM” in growing CE networks is valuable to overcoming this challenge and was a key area of the recent interoperability testing.
Another critical aspect of growth is dealing with multi-technology—not just multi-vendor—interoperability. As CE networks scale, there is an increasing mix of Ethernet switching, MPLS and, most recently, MPLS-TP internetworking emerging. One potentially complex area that was also tested was validating the operation and survivability of intersecting Ethernet and MPLS-TP rings in a multi-homed topology. The “ERPSv2 and VPLS Interworking” test validated that standards-based G.8032 Ethernet protected rings and MPLS-TP VPLS rings can interoperate, or more significantly “co-operate,” to allow complex multi-technology networks to deliver reliable end-to-end services.
To learn about these aspects of scaling and dealing with complex CE networks check out the EANTC white paper for more details.
