Questrion about Netowrk Porcessors >=10Gb/s

Hello,

I'm working on project of hybrid electro-optical edge node.
This node shall be capable of receiving several IP streams and aggregate
those IP packets into large constant-size slots. Slots will be
transmitted via optical link 10Gb/s.
Is there any commercial available NPU that can handle this operation
with speed 10Gb/s in duplex mode (2x10Gb/s in total)?

I found only: Xelerator X11, and Intel IXP23xx.

Where shall I look for this sort of devices?
Can You please suggest any brands? names? websites?

Thank You,
Robert
