DIGI-G4 Scales OTN Line Card Capacity by 4X and Reduces Power by
50 Percent
PMC-Sierra, Inc. (PMC®) (Nasdaq:PMCS), the semiconductor and
software solutions innovator transforming networks that connect,
move and store big data, today introduced its latest DIGI OTN
processor, enabling the transition to 400G line cards in OTN
switched metro networks. The new DIGI-G4 builds on the success of
PMC’s DIGI-120G, which is globally deployed in service provider and
hyperscale data center wide area networks (WANs) today. It is the
industry’s densest single-chip 4x100G OTN processor with 50 percent
less power per port than the previous generation. DIGI-G4 addresses
the needs of an SDN-ready, encrypted transport infrastructure. It
delivers the capacity, security and flexibility required for 400G
line cards in packet optical transport platforms (P-OTP), ROADM/WDM
and optimized data center interconnect platforms (see
infographic).
Big data is driving metro network bandwidth to double to 110Tb/s
by 20171, leading service providers to deploy additional OTN
switched 100G optical capacity. In response, OEMs are scaling their
transport platforms with 400G OTN line cards. DIGI-G4 is the
industry’s first OTN processor to enable single-chip 400G line
cards for OTN switching on P-OTPs. It increases 10G, 40G and 100G
line card port density by 4X with flexible client mapping of
Ethernet, storage, IP/MPLS and SONET/SDH, while reducing power by
50 percent per port. DIGI-G4 builds on the IP from DIGI-120G,
enabling customers to maintain their rich feature set and software
investment, which reduces time to market by up to six months and
lowers development costs.
“China Mobile has already deployed one of the world’s largest
100G OTN switched networks and is now moving to further increase
the capacity and density,” said Li Han, deputy director of the
Network Technology Research Institute, China Mobile Communications
Co., Ltd. “Our network must scale to meet bandwidth needs while
reducing overall power consumption. Solutions like PMC’s DIGI-G4
that meet 100G density and power targets are needed for China
Mobile to fulfill our end-to-end OTN strategy.”
DIGI-G4 Secures Hyperscale Data Center WAN
As the majority of enterprises migrate their workloads to the
cloud, there is an increasing need for secure optical transport
connectivity to and from, as well as between data centers. Unlike
encryption at other networking layers, securing the optical layer
with OTN guarantees 100 percent throughput, regardless of packet
traffic size, with ultra-low latency. DIGI-G4 delivers multi-rate,
sub-180ns latency OTN encryption, allowing cloud and communications
service providers to ensure security without compromising
performance. DIGI-G4 supports sub-wavelength OTN encryption and is
compatible with OTN switched networks. These capabilities, combined
with the densest 10G/40G/100G Ethernet ports, enables a new class
of low-power, high-capacity transport platforms optimized
specifically for the hyperscale data center WAN interconnect market
(see whitepaper).
“Without DIGI-G4 the industry would be challenged to transition
to 400G OTN switched metro networks,” said Babak Samimi, vice
president of marketing and applications for PMC’s Communications
Business Unit. “The world’s leading OEMs are designing around
DIGI-G4 because our solution allows them to scale their product
portfolios to the highest capacities at half the power per port,
while leveraging their existing DIGI software investment. Coupled
with new capabilities like OTN encryption, we’re solidifying PMC’s
position as the industry leader in OTN processors.”
DIGI-G4 Delivers Flexibility for Transport SDN
According to Infonetics, three quarters of service providers are
planning to deploy transport SDN2 to achieve multi-layer
convergence, enable on-demand virtual network capabilities and
deliver on-demand bandwidth services. OTN switching is required to
extend SDN to optical transport in order to virtualize shared
optical resources and enable on-demand provisioning of high-speed
connections between data center customers. DIGI-G4’s unique
architecture allows OTN and packet traffic to be flexibly groomed
and switched together over 100G optical wavelengths in a single
converged platform. It can also dynamically provision, switch and
scale optical connections from 1Gb/s to 100Gb/s bandwidth without
traffic interruption to enable bandwidth-on-demand services (see
whitepaper).
OTN Software Accelerates Time to Market
DIGI-G4 includes PMC’s field-proven, carrier-qualified OTN
Switching Software Development Kit (SDK), providing customers with
the lowest risk, fastest time to market and lowest cost of
development. Building on the DIGI family code base, common APIs
allow OEMs to reuse their software with DIGI-G4. PMC is the only
solution with an application-driven adapter layer to abstract
device complexities into a set of pre-configured applications for
the simplest software integration.
