Tokyo Stock Exchange Lights Low-Latency “Arrownet”

The Tokyo Stock Exchange has implemented a low-latency network supporting an MPLS network called “arrownet” that is designed for fast, high-volume data communications with latency of less than two milliseconds, with a measured value less than one millisecond from the access point to the data center.
The network is configured as a ring using highly Juniper Networks “M Series” routers placed with dual redundancy, making arrownet infrastructure highly fault tolerant. The configuration also allows for fail-over from TSE’s primary data center to its backup center without intervention on the part of the securities firms.
The TSE is putting in place a number of IT innovations, including arrownet, to pave its way to becoming a “Universal Exchange” for securities, options and derivatives trading.
“The ultra low-latency response investors have been experiencing since the release of arrowhead proves that arrownet is delivering on our vision to supply a world-class trading infrastructure that is able to compete on equal terms with, or even surpass, any other financial market in the world,” says Yoshinori Suzuki, managing director and CIO of the Tokyo Stock Exchange.
TSE offers securities firms the opportunity to co-locate their systems within the Exchange’s data center, minimizing inter-system latency, while connecting them to their offices and their data centers via arrownet’s dual access points. Furthermore, the flexibility and scalability of arrownet’s architecture enables TSE to interconnect with overseas financial institutions and exchanges.

AboveNet Offers Latency of 1 Millisecond

AboveNet, a provider of high-bandwidth connectivity solutions, has deployed Ciena’s 2RS module for the “FlexSelect Advanced Services Platform” as part of the service provider’s recently introduced “Agility Guarantee” program, which provides industry-leading ultra-low latency service level agreements
The new module helps reduce delay by up to 20 percent, enabling AboveNet to offer its customers high-bandwidth connectivity for critical, latency-sensitive applications, such as algorithmic or futures trading, VoIP and video.
AboveNet serves its business and carrier customers over a private fiber optic network that delivers network connectivity and IP services in and among top U.S. metro markets and globally.
With the Agility Guarantee program, AboveNet is now offering its financial services, energy trading, online gaming, and media and entertainment customers a network solution that delivers round-trip latencies as low as sub-one millisecond for some services.
The program uses real-world, round-trip numbers for the end-to-end network – not one-way metrics, averages or SLAs for only part of the network, such as between points of presence.
“When tiny fractions of a second can mean the difference in huge amounts of revenue, latency is by far the top priority and key decision criteria for our target customers, which is why our fiber-intensive private optical network gives us a huge advantage over competitors that have lots of intermediary routers, switches and other equipment that simply add more latency and potential points of failure to the network,” says MaryBeth Nance, AboveNet executive director.

Special Invitation:


EtherNEWS Subscribers are invited to an exclusive training session at CTIA in Las Vegas, 22-26 March. Reserved for service providers’ technical staff, the one hour session will provide a complete overview of the latest Ethernet OAM standards and the MEF 22 backhaul framework. Limited to only 30 participants, this will be an exceptional learning and networking event. Training will be provided by the Carrier Ethernet Academy, founded by MEF board member & Ethernet pioneer Craig Easley. Reserve your spot: Ethernet Training.

This Month’s Issue

Each EtherNEWS edition covers a wide range of applications and solutions related to Ethernet service creation, service assurance, SLA & QoS monitoring and evolving industry standards.

This month we feature a complete introductory video training course to Carrier Ethernet technology, with content tailored to service providers’ sales, product management, marketing and support staff. Designed to introduce Ethernet’s key capabilities, features, challenges and service differentiators from the carrier perspective, this course explains Ethernet VPLS, E-Line and ELAN services, related MEF standards, and Ethernet Operations, Administration & Maintenance (OAM) methods used to monitor and manage these services.

Application Highlights

Take a 25 minute high-level training course covering Carrier Ethernet technology basics – with content tailored to service providers’ sales, product management, marketing and support staff. It’s a quick way to get up to speed on Carrier Ethernet and brush up on its terminology and acronyms, and reinforce your knowledge of Carrier Ethernet for business services and wireless backhaul applications.

You need to upgrade your Flash Player

The feature application video in this EtherNEWS edition is also available as a free Video Podcast. Download Now.

Essential Reading: Optimizing Latency & Backhaul Efficiency

Keeping latency in check is critical for quality of service (QoS) of demanding Ethernet wireless backhaul, wholesale and business services. Given that Ethernet bandwidth is considered relatively “inexpensive”, some providers increase throughput to reduce latency and keep performance within strict SLA tolerances.

However, the relationship between bandwidth and latency is anything but simple in packet-based networks, where increasing throughput can sometimes have no effect on delay, or even increase it under certain conditions.This paper explores the key sources of delay, and techniques to optimize latency without consuming excess bandwidth. These guidelines allow providers to use their network resources as efficiently as possible, while assuring the QoS of critical, real-time services.
