Abstract:
Carrier-grade network management was optimized for environments built
with monolithic physical nodes and involves significant deployment,
integration and maintenance efforts from network service providers.
The introduction of virtualization technologies, from the physical
layer all the way up to the application layer, however, invalidates
several well-established assumptions in this domain. This draft opens
the discussion in NFVRG about challenges related to transforming the
telecom network infrastructure into an agile, model-driven production
environment for communication services. We take inspiration from data
center DevOps regarding how to simplify and automate management
processes for a telecom service provider software-defined
infrastructure (SDI). Among the identified challenges, we consider
scalability of observability processes and automated inference of
monitoring requirements from logical forwarding graphs, as well as
initial placement (and re-placement) of monitoring functionality
following changes in flow paths enforced by the controllers. In
another category of challenges, verifying correctness of behavior for
network functions where flow rules are no longer necessary and
sufficient for determining the forwarding state (for example,
stateful firewalls or load balancers) is very difficult with current
technology. Finally, we introduce challenges associated with
operationalizing DevOps principles at scale in software-defined
telecom networks in three areas related to key monitoring,
verification and troubleshooting processes.
