• Oleg reported about Cenk's efforts to disentangle RPL and Trickle and improve efficiency

Forwarding Table

• Martin reported about a concept for a Forwarding Information Base and a Routing Information Base
• Oleg asked about a concept how the FIB is organized if more than one routing protocol is active
• Emmanuel pointed out that combining metrics of different routing protocols should not be considered
• Oleg asked about a concept to store different address types
• Martin replied that full IPv6 addresses (128 bits) should be supported, but maybe in a separate data structure
• Oleg reported that Fabian Nack at FUB might start work on this topic soon with a focus on multi-transceiver support

Timers

• Consensus was made that a unified and simplified timer API is desirable
• Further discussion is done on the mailing list
