Wily,
Here is the feed Tom (Davin???) is referring to. The date of the vendor technical release was Feb 17, 1999 and can be found at
nasdaqtrader.com
The impact of not switching to this feed could be bottlenecks at the Vendor end. The current feed structure can only handle so much data before it starts to buffer and delay.
--------
The Nasdaq Stock Market© will soon introduce an Internet Protocol (IP) multicasting version of its Level 1 ServiceSM, Nasdaq Quotation Dissemination ServiceSM (NQDS), and Nasdaq Trade Dissemination ServiceSM (NTDS) data feeds. Nasdaq© expects the new data feeds to be ready for subscriber testing in April 1999 and for production use shortly thereafter. To ensure adequate testing time, Nasdaq market participants and market data vendors are encouraged to place orders for the new IP multicasting services as soon as possible. MCI WorldCom is now accepting orders.
Background Information
The Nasdaq Stock Market has experienced an incredible increase in its message traffic rates over the last three years due to share volume growth and market structure changes. Since 1996, Nasdaq has seen total message traffic rates for its quotation feeds rise by over 325% and its trade feed by 200%. As traffic rates continue to climb, Nasdaq will need to increase the bandwidth for its data feed services. By moving to IP multicasting protocols, Nasdaq can more easily increase its bandwidth as needed. Unlike the current bisynchronous protocol, the IP multicasting protocol is more scalable and portable to program.
In conjunction with the protocol change, Nasdaq also plans to increase the bandwidth for its data feed services by over 50%. Therefore, if timely data is critical to your business, Nasdaq strongly encourages you to begin testing the IP multicasting data feeds as soon as possible. For up-to-date information on the IP multicasting implementation schedule, please refer to the Release Schedule section of the Nasdaq TraderSM Web site beginning March 1999. |
