Juniper Networks officials are continuing to push their product
portfolios toward 400 Gigabit Ethernet as they eye the bandwidth demands
that will be coming with the migration to 5G networks and the
increasing adoption of such modern technologies as cloud computing, 4K
video, and augmented and virtual reality.
As part of the 400GbE
roadmap unveiled July 24, the company later this year and in 2019 is
bringing 400GbE capabilities to its PTX, QFX and MX series switch and
router lineups aimed at data centers, WANs, enterprises and
telecommunications for use cases such as cloud services, hyperscale
environments, network backbones and data center interconnects. The
refresh of the switches and routers is the most recent step in Juniper’s
push toward 400GbE, including the announcement last month of its
400GbE-capable Penta Silicon.
In addition, company officials said
plans are underway for new generations of ExpressPlus and Q5 silicon to
support 400GbE, as well as other features.
According to Manoj Leelanivas, executive vice president and chief
product officer at Juniper, the work the vendor is doing around
400GbE—not only with upgrades to its products but its work to ensure the
QSFD-DD spec for 400GbE kept the same interface densities as those with
100GbE—will give businesses an easy migration path and improve both
bandwidth and costs.
“Customers will realize the economic benefits
of a 400GbE solution that breaks the historic cost-per-bit economics
cycle that has been seen time and time again,” Leelanivas wrote in a post on the company blog.
“Delivering routing and switching platforms that offer investment
protection when transitioning from 100GbE to 400GbE will also inspire
our customers to pursue new applications—thanks to the significant
amount of bandwidth now available to them.”
The industry is primed for the arrival of 400GbE shipments. According to a report
earlier this year by analysts at Crehan Research, initial shipments of
400GbE switches will come this year and grow significantly. By 2022,
most of the Ethernet network bandwidth in data centers will be 400GbE.
Shipments of 100GbE systems will surpass those of 40GbE, three years
after initial shipments hit the market, illustrating the demand for
faster networks.
"Beginning
with high-density 100GbE systems, we entered a new era of much faster
data center switch upgrades, and that trend is predicted to continue
with 400GbE," Seamus Crehan, president of Crehan research, said in a
statement in January. "With its expected market-leading price per
gigabit and no foreseeable shortage of demand for higher-speed
networking capacity in cloud data centers, 400GbE should surpass a
million ports shipped in less time than it took 100GbE to reach that
threshold."
Organizations are increasing the capacity of their
data centers to address growing high-performance applications and as the
connectivity in their servers moves to 50GbE and 100GbE uplinks,
according to Juniper officials. The vendor is enhancing its QFX series
of switches with 400GbE capabilities, including the 3U (5.25-inch)
QFX10003, which will offer 32x400GbE and can scale up to 160x100GbE. It
will be powered by the next-generation Q5 silicon and offer a deep
buffer enabled by Hybrid Memory Cube, which will enable it to handle
spikes in network traffic and reduce application latency, they said.
It will be available in the second half of this year.
The
1U (1.75-inch) QFX5220 will run on merchant silicon and offer
32x400GbE, as well as 50GbE, 100GbE and 400GbE interfaces for server and
inter-fabric connectivity. The switch will be available in the first
half of 2019.
For the WAN, Juniper officials introduced the 3U
PTX10003 Packet Transfer Router for backbone, peering and data center
interconnect applications. The system can be used for high-density
100GbE ad 400GbE deployments and is aimed at scale-out and cloud
environments. The router, due in the second half of the year, includes
native MACsec support for 160x100GbE and FlexE support for 32x400GbE
interfaces.
As part of the 400GbE roadmap, Juniper officials also pointed to the MX Series 5G Universal Routing Platform, which was announced in June and is powered by the new Penta Silicon and offers 400GbE interfaces.
