What you need to know:
- NASDAQ OMX is updating its bandwidth recommendations for the Global Index Data Service (GIDS) to reflect recent traffic trends.
- NASDAQ OMX is advising firms to increase bandwidth allocations for the GIDS data feed.
Why is NASDAQ OMX updating its bandwidth recommendations?
NASDAQ OMX® provides bandwidth recommendations for its proprietary and managed products at the request of the market data community. Periodically, NASDAQ OMX reviews and updates its bandwidth recommendations to reflect message traffic trends and expected system changes.
What are the bandwidth recommendations for NASDAQ OMX data feed products?
Based on its review process, NASDAQ OMX is increasing the bandwidth recommendations for the (Global Index Data Service) GIDS data feed:
Data Feed Name | Current Bandwidth Recommendation (per data center connection) |
Updated Bandwidth Recommendation (per data center connection) |
Network Protocol Options |
---|---|---|---|
NASDAQ OMX Global Index Data Service 2.0 (GIDS 2.0) | 10 Megabits (Mb) | 15 Mb | SoupBINTCP and MoldUDP64 |
Please refer to the NASDAQ OMX Bandwidth Recommendation document for the full NASDAQ OMX product list.
Please note that NASDAQ OMX bandwidth recommendations are based on one-second peak message rates. Firms may wish to use a higher bandwidth allocation than the recommended amount if they are sensitive to sub-second data peaks.
Does NASDAQ OMX throttle its proprietary data feeds to the stated bandwidth rates?
The answer varies based on the data feed and protocol option. As outlined on the Data Feed Specifications page, NASDAQ OMX supports multiple delivery options for its proprietary data feed products. NASDAQ OMX offers both SoupBINTCP and MoldUDP versions of the GIDS data feed.
SoupBINTCP is based on the TCP/IP network protocol suite. Because the protocol assures guaranteed delivery, NASDAQ OMX data rates are throttled at the port level so as not to exceed the customer-specified bandwidth allocation.
MoldUDP, which is based on the UDP/IP network protocol suite, does not have the same network limitations. With the exception of the NASDAQ Level 2 and NASDAQ TotalView-Aggregated products, NASDAQ OMX does not apply data throttles to its proprietary MoldUDP data feeds.
When do I need to upgrade my NASDAQ OMX bandwidth allocations?
NASDAQ OMX issues only bandwidth recommendations. It is up to each data feed customer to manage network configurations as they see fit. Because NASDAQ OMX data feeds may burst higher in the sub-second, customers are encouraged to analyze their own network usage statistics when making a bandwidth purchasing decision.
Where can I find additional information?
- Refer to the NASDAQ OMX bandwidth recommendation document on the NASDAQ OMX Trader® website.
