CONNECTING ICN „ISLANDS”

ICN ICN ICN Data source Non-ICN network

Data interest … …

One of deployment problems with ICN: „islands” separated by traditional network Manual tunnels set-up to enable communication: tedious, error-prone etc.

a) Available in cache? b) Pending in PIT? c) If not, then forward

SLIDE 3

SDN ENHANCED ICN FORWARDING

ICN ICN ICN SDN SDN controller ICN repository “app”

What’s the nearest ICN node containing the data object of interest? a)Forwarding entry available ? Then just forward  b)If not, then ask controller

SDN SDN

Update forwarding entries Perform any action to forward via legacy network (e.g., rewrite IP, push MPLS,...)

Data source Non-ICN network with SDN gateways

Demo: Non-ICN network = IPv4 Controller = Ryu + OpenFlow 1.3 SDN switch = CPDQ softswitch modified to handle eBPF programs to match on ICN names ICN node = nfd 0.4.1 ICN app = Ryu app gathering ICN routing information
