Three Elements to IP/MPLS Success in the Microwave Access

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.

3 Secrets to IP/MPLS in microwave backhaul access

In the Air Tonight: Ethernet

Since the advent of Internet Protocol (IP), many microwave backhaul networks have been based on Ethernet standards. And more recently, Carrier Ethernet has become used extensively in microwave segments of backhaul networks. Typically, Carrier Ethernet exists in the access section of the backhaul.

In contrast, in a mixed medium backhaul, the fiber portion of the infrastructure that lives in the metro and core networks will have a basis in IP/MPLS. And deploying services across multiple domains using different technologies presents many challenges, chief among these:

  • Additional provisioning touchpoints
  • Delayed site and service turn-up
  • Lack of end-to-end visibility

Integrated Microwave Solutions

The key to solving these problems lies in deploying a common transport technology across all the affected mediums in the backhaul. Of course, the highest technology—IP/MPLS in this case—would seem the best choice. However, IP/MPLS has more akin to fiber and does not closely integrate with microwave, traditionally. Of course, all traditions are subject to breaking, and this one’s no different.

Aviat’s CTR platform combines IP/MPLS and microwave technologies into a tightly integrated device known as the microwave router. With the Aviat CTR microwave router serving as the backbone of the network, an operator can easily implement IP/MPLS across all three backhaul subsections, overlaying the core, metro and access. But mere hardware is not enough. Aviat’s exclusive SaaS-based network application, AviatCloud, and expert professional services and support from AviatCare are critical to the success of a CTR microwave router backhaul transformation.

Case Study on IP/MPLS Over Microwave Backhaul

We’ll do a deep dive into how to analyze the network architecture, deal with protocol differences, optimize for end-user services from 2G to LTE and more.
