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.
