Home / Customer Excellence / Customer Stories / Customer Stories: OSTTRA


OSTTRA is a financial technology company formed through the merger of MarkitServ, Traiana, TriOptima, and Reset. More than 1400 employees across 8 global offices develop and operate post-trade infrastructure for global financial markets, connecting thousands of counterparties on multi-asset networks that underpin the post trade lifecycle.

The challenge

Defragmentation of a legacy enterprise network for seamless data transfer between global sites

OSTTRA was facing several challenges with their network infrastructure and needed a simplified internal core network solution. The main requirement was to establish seamless connectivity between global sites using a fully meshed topology across different continents, with high bandwidth, while retaining full control over their IP network layer.

Given the nature of their business within the financial sector, there are several specific business-critical requirements. A reliable 'always-on' network is at the top of the list, providing uninterrupted service and low-latency connections for swift and seamless data transmission. Security is paramount, necessitating secure private connectivity between critical sites to safeguard sensitive financial data.

Furthermore, OSTTRA requires support for Layer 2 transparency, with features such as support for jumbo frames with an MTU of 9100, and protection mechanisms to ensure data integrity and confidentiality.
The solution

Multiple EVPLs – Ethernet private connections with high bandwidth and unrivalled flexibility

We successfully addressed all customer requirements, and here are some of the key benefits of the Arelion solution for OSTTRA:
  • Multiple 10Gbps Ethernet EVPL services, establishing point-to-point links between all sites, ensuring dedicated high-speed connectivity.
  • A combination of 10GE and 100GE ports connecting each site to Arelion’s high-capacity backbone network, for maximum resilience and scalability.
  • Dedicated Access tails to off-net locations, granting access to over 180 supplier NNI’s and more than 450 accredited local access partners, extending connectivity reach and coverage.
  • Optional 100G or 10G Cisco Network Interface Devices (NIDs) at each site, with performance data accessible through the MyArelion portal, for full visibility and control of network performance.
  • MSOP (Multiple Services on One Port) functionality, enabling local Internet breakout or Cloud Connect services on the same port, for additional flexibility and service customization.


Arelion’s solution fully meets OSTTRA's requirements for a scalable and reliable network, ensuring business-critical communication for all sites:
