Bell Canada Launches Self-Serve Network as a Service

Bell Canada announced on 10 September the Bell On-Demand Network, which it describes as the country's first network-as-a-service platform aligned with the 7 customer experience attributes defined by Mplify, the industry body formerly known as MEF: on-demand, observable, manageable, programmable, secure, modular and flexible. TelecomTV carried the announcement in its 10 September roundup. The platform runs on Bell's fibre network with Cisco 8000 Series Secure Routers underneath, and the operator's description is that business customers can, through a single self-serve platform, "autonomously order, activate, manage and scale connectivity". The first product is On-Demand Internet, available in Ontario and Québec wherever Bell has deployed fibre, with additional networking, security, cloud connectivity and automation capabilities to follow. Bell's CTO Mark McDonald said customers "can now provision, scale and adjust their network in real time, getting the exact bandwidth and services they need, the moment they need them". No price, no provisioning time, no API documentation and no customer figure were published.

The customer configures, the operator does not pre-package

I have argued for some time that the natural end state of differentiated connectivity is slicing as a service: a platform through which third parties discover, configure, reserve and consume network resources on demand, because enterprise CIOs know their connectivity needs better than the operator does and are used to configuring cloud services rather than selecting from a catalogue. Bell's launch is that model applied to fixed access, and it is worth noting what is different from the 3 mobile launches of the past 3 weeks. EE sells a priority lane as a tariff, Vodafone sells a predefined quality profile through an API, and Telstra sells a slice for 1 application chosen by the operator. In each of those the operator decides what the product is and the customer decides whether to buy it. In Bell's description the customer decides the bandwidth and the timing, and the operator's role is to make the change when asked. That is the inversion the slicing-as-a-service argument depends on, and Bell states it as the product rather than as a roadmap.

Fixed first, because bandwidth on fibre is a reservation

It is not an accident that the self-serve model arrives on fibre before it arrives on mobile. When Vodafone launched quality on demand I wrote that a priority is not a reservation: a mobile profile improves the customer's place in the queue on a congested cell but does not guarantee what comes out of it, and the profile parameters were not published. On a dedicated fibre access line a bandwidth change is a reservation. The capacity exists, the router policy is deterministic, and the operator can honour the customer's chosen figure without a proof-of-value engine to check whether it did. That is why Bell can let the customer set the number and why the mobile operators cannot yet. It is also why the interesting part of Bell's roadmap is the part that is not launched: cloud connectivity and security are where the customer's requirement starts to depend on a second network and a second party, and the on-demand model will be tested at the first boundary it has to cross. Mplify's 7 attributes describe the customer's experience inside 1 provider's platform. They do not describe what happens when the customer's agent asks 2 providers for the same thing.

Programmable is the attribute that matters

Of the 7 attributes, 6 describe a good portal. The seventh, programmable, is the one that decides whether this is a self-serve web page or a network resource that a customer's own systems can consume. Bell's announcement describes a platform, not an API, and does not say whether the ordering, scaling and observability functions are exposed to the customer's software or only to a person logged into a portal. The distinction is the one I drew at DTW Ignite: the APIs that ship are the ones that ask the network a question, and the ones that ask it to change its behaviour on a third party's instruction are harder. On-Demand Internet is the second kind, in the easiest domain. If it is programmable in the Mplify sense, a customer's cloud automation or an enterprise agent can scale the access line up before a backup window and down after it without a human on either side, and Bell has built a resource the customer's software can reason about. If it is a portal, Bell has built a better ordering experience. The announcement does not say which, and it is the first thing a CIO evaluating it should ask.

What has not been published

No price relative to a standard business fibre contract, no provisioning time for a bandwidth change, no statement of whether the platform is API-accessible or portal-only, no minimum term or change frequency, no customer count and no date for the cloud connectivity and security capabilities. 4 things to watch. First, published API documentation, which is the test of the programmable attribute. Second, the price of a bandwidth change against the price of a permanent upgrade, because the on-demand model only pays for the customer if variable capacity is priced below fixed capacity over the period it is used. Third, whether Bell extends the same self-serve model to its mobile network, where it would need 5G standalone slicing and a service level of the kind Telstra attached to its slice. Fourth, whether the cloud connectivity capability, when it arrives, lets the customer configure the far end as well as the access line, which is the first crossing of an administrative boundary and the point at which slicing as a service stops being a single-operator product.
