Cable infrastructure has moved away from the monolithic CMTS/CCAP system. It isn’t well-suited to the heavy and varied demands of customers. The modern cable infrastructure increasingly consists of a virtual CCAP, or vCCAP, with many Remote PHY or Remote MAC-PHY nodes. The new architecture shortens the coax cable distance to the customer and scales to meet growing needs. It allows faster, cleaner data transfers.

The new approach to cable infrastructure management raises new issues. Having one box may be restrictive, but managing it is simple. When the infrastructure consists of multiple software and hardware components, interoperability becomes an important concern. During the upgrading process, dedicated and virtual CCAP systems may work side by side. A good orchestration system lets all the pieces work together.

Distributed Access Architecture (DAA)

The older cable infrastructure was primarily oriented toward TV transmission. The importance of UDP and TCP/IP has greatly increased, forcing a change in priorities. Distributed Access Architecture (DAA) is better suited to handling IP traffic over Ethernet, reducing the need for RF transmission over coax. With Remote PHY, coax can be used just for the “last mile.”

This approach lowers costs, increases scalability, and allows faster data rates with less latency. The infrastructure is in a better position to meet the challenges and opportunities of the future.

Managing a multi-vendor infrastructure

The move to a virtualized and distributed infrastructure means working with products from multiple vendors. Virtualization reduces vendor dependency. A vCCAP runs on generic hardware. Any machine which meets the specifications will do. But the software components are more likely to come from different vendors, as are Remote PHY nodes.

If these components have APIs that follow generally accepted standards, they’re all manageable. it’s just the quantity and variety of them which is daunting. Just as a sample of what’s involved:

  • Deployment and authentication of Remote PHY nodes.
  • Installation of new accounts and customer services.
  • Registration of changes in service levels.
  • Testing and maintaining the quality of service.
  • Prompt identification and remediation of service outages.
  • Maintaining an inventory of devices in operation.
  • Security monitoring.

Intraway’s Symphonica Service Orchestrator lets all these services work together smoothly, and it lets administrators manage them all from a single console. Maintaining and updating the cable infrastructure becomes simpler.

Combining the old and new

No one is going to replace an entire cable infrastructure in a day. There will be a long period in which old-style CCAP systems work side by side with virtualized ones. Monolithic CCAPs weren’t designed with interoperability in mind. Making them work with RPDs is possible but takes some work.

One approach is to have separate management for the old and new systems. That means more work, though, and poorer service for the customers on the old systems. Symphonica allows coordinated management of all CCAP and RPD units from one place.

Managing Remote Phy devices

Remote PHY means not only a lot of devices but devices in a lot of locations away from the offices. Hands-on management has to be the exception. It’s a big job to keep track of all of them for inventory and maintenance purposes. They need to be monitored to make sure they’re working properly and catch failures quickly. They need to be authenticated in a way that catches any tampering. Symphonica manages inventory and authentication for all Remote PHY nodes.

Efficiency and central cable infrastructure management

With orchestration tools that handle the entire infrastructure from one place, cable operators enjoy many advantages. They can deploy services, manage inventory, identify problems, and expand the scope of service with a minimum of fuss. This means more income and more business opportunities. Contact us to learn how Symphonica can help you to tame your infrastructure.
