Bandwidth Updates

In conjunction with the decommission of the 1G Feed, some bandwidth adjustments will be applied to the remaining Feeds to provide more flexibility to Participants who wish to receive BOX market data over a single connection. Participants are reminded not over-subscribe to market data (i.e. subscribe to multiple services of the feed on a connection where the total bandwidth would exceed the capacity of the connection).

Service	“A” Feed Bandwidth	“B” Feed Bandwidth
Top of Book HSVF	10Gbps	1Gbps
Market Depth HSVF	1Gbps	1Gbps
PIP, Complex Order HSVF	1Gbps	1Gbps
