Tokyo Stock Exchange's arrownet Deploys Juniper

The Tokyo Stock Exchange (TSE) has deployed low-latency, ultra-reliable, high-capacity network powered by Juniper Networks' M Series Multiservice Edge Routers and Junos operating system. Project "arrownet" is TSE's next-generation securities trading system, paving its way to becoming a Universal Exchange for securities, options and derivatives trading. Financial terms were not disclosed.


TSE selected Juniper Networks M320 and M120 Multiservice Edge Routers to form the core and access layers of the new network. The arrownet MPLS network is designed for fast, high-volume data communications with latency of less than two milliseconds (measured value is less than one millisecond) from the access point to the data center. The network is configured as a ring using 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, reducing their burden.
