SMPTE Publishes PNM Flow
Management Report
S

MPTE, the organisation whose
standards work has supported a
century of advances in entertainment
technology and whose membership
spans the globe, has announced
the publication of the Report of the
Study Group on Flow Management in
Professional Media Networks.
The new, 52-page report investigates
current and future technologies for
media content flow management in
professional media networks (PMN),
explores user requirements, examines
potential transmission methods for
management commands, provides
an overview of existing standards
and specifications now available to
the professional media industry, and
offers a series of recommendations to
the industry including some for future
work.
"The Study Group report delves
into critical considerations for
establishing effective, interoperable
flow management across IP networks,"
said Howard Lukk, SMPTE Director of

Engineering and Standards.
"Based on the expertise of SMPTE
Members and input from across
the industry, the report offers a
solid foundation on which to build
future standards work - and thereby
accelerate the industry's shift toward
more efficient, scalable, agile,
and flexible IP infrastructures and
workflows."
Flow management is the mechanism
for controlling how real-time media
flows are guided through a fabric
of Ethernet switches from senders
to receivers with the appropriate
functionality of media clean switching,
reserved media bandwidth, and
guaranteed required quality of service
(QoS).
Ideally,
operators
managing
flows within internet protocol (IP)
infrastructure should be able
to use router panels
and interfaces from
the familiar serial
digital
interface

(SDI) infrastructure, but the industry
has yet to put forward the necessary
underlying
professional-grade
protocols and mechanisms for this
purpose. While work is already in
progress within some organisations,
open standards are not yet available.
The SMPTE report addresses the
gap in existing standardisation and
ultimately makes recommendations

InForm

for SMPTE standards work in the
areas of QoS profile, congestion
management, and authentication
in PMN. It also discusses the need
for harmonisation of device control
protocol standards currently available
to the industry. Recommendations for
the broader media industry include
topic areas such as flow switching
methods, software-defined networking
(SDN) control, and anomaly detection.
The Report of the Study Group on
Flow Management in Professional
Media Networks is available now from
SMPTE.
