Cisco has developed a plug-in to integrate the ASR 1000 Series Router
(ASR1K) into OpenStack to offload L3 capabilities on to dedicated routing hardware. The plug-in was demonstrated at Cisco Live in a Proof-of-Concept environment. We are planning demos of a Cloud solution based on the ASR1k plug-in at the OpenStack Summit in Vancouver. The plug-in is considered open source and will be submitted upstreamed into OpenStack. It will also be available from Cisco’s Neutron Tech-Preview repository
OpenStack offers a reference software implementation for Layer 3 functionality. Routing, static NAT (Floating IPs) and dynamic NAT/SNAT (VM “Internet” access) are handled by the l3agent that runs part of the neutron component. The L3 agent relies on Linux IP Tables to define forwarding rules. With that comes a critical scalability issue as Linux IPTables has inherent scaling shortcomings. For highly-scalable clouds with many route and NAT operations, this becomes a serious bottleneck.
Cisco offers the ASR1K routing platform to be used in Data Centers typically for WAN edge operations. It performs NAT and L3 forwarding in hardware and provides L3 high-availability (HSRP). The ASR Config Agent builds upon the same technology utilized for the integration of the Cisco Cloud Services Router (CSR1000v
) into OpenStack.

Talking with customers in various segments, one common trend seems to be emerging for branch deployments: customers are trying to strike the right balance between 2 opposite ideals. On one side they want to deliver great user experience and drive employee productivity but on the other side they are being asked to reduce cost and operate more efficiently. It is becoming increasing challenging to strike this right balance, especially with newer technologies like virtualization, BYOD and Cloud.
