Clients should increase their available bandwidth for most Nasdaq feeds, officials say.

Subscribers will need more bandwidth to consume the Nasdaq TotalView ITCH feed, the Nasdaq Best Bid and Offer and Last Sale products, the Nasdaq Trader FilterView feed, the PHLX Depth of Market feed, and the Nasdaq, BX and PSX MatchView feeds will increase, while the bandwidth required to consume the Nasdaq TotalView Aggregated feeds and TRT Trader Filterview product will decrease.

In a client notification, Nasdaq officials say the exchange periodically reviews and updates its bandwidth recommendations, based on one-second peak message rates, to reflect message traffic trends and expected system changes.

"Nasdaq issues only bandwidth recommendations. It is up to each datafeed customer to manage network configurations as they see fit. Because Nasdaq datafeeds may burst higher in the sub-second, customers are encouraged to analyze their own network usage statistics when making a bandwidth purchasing decision," the notice says.
