4 Open Hardware Switches White label switches Original Design Manufacturers (ODM) - Accton/Edge-Core, Quanta Often based on Broadcom ASICs - Trident II (40GE) - Tomahawk (100GE)

5 Emerging Open Switch Ecosystem

6 Open Compute Project Started by Facebook in April Build servers and data centres following the Open Source model. Open Networking Project announced in May Build an open network switch. Current Projects: - Intel: switch specification. - Mellanox: switch specification. - Cumulus Networks: ONIE (Open Network Install Environment). - Broadcom: switch specification.

7 Open Network Install Environment (ONIE) Open Network Install Environment (ONIE) - Combines boot loader with modern Linux kernel and BusyBox - Environment for installing any firmware - Open Compute Project - Also supported on commercial switches - Dell S Dell S Juniper OCX100 - Founding members: Accton, Agema, Big Switch Networks, Broadcom, Cumulus Network, Dell, Penguin Computing, Quanta

14 Software Defined Networking Approaches Manipulating forwarding tables - OpenFlow On top of traditional protocols and NMS - I2RS, etc Overlay networks - VXLAN, VMWARE NSX, etc

15 Vision Behind Software Defined Networking Separation between Control Plane (policy) and Data Plane (packet forwarding). Logically centralised policy (control plane). - Program (controller) that reads policy configurations, compiles it to forwarding rules and sends those to network elements à Software Defined Networking. Dumb switches (data plane). - Firmware does packet frame forwarding only. Standardised protocol between switches and controllers (e.g. OpenFlow). Possibility of different vendors for switches and controllers. - More competition.

18 SURFnet/TNO EU Funded OpenFlow project GN3plus Open Call Project (CoCo). October 2013 March 2015 (18 months). Budget Eur 216K person months. Partners: SURFnet (NL) & TNO (NL). Five work packages: - WP1: use cases & market demand - WP2: architecture, design & development - WP3: experimental validation - WP4: dissimination - WP5: project management

19 Community Connection (CoCo) Service Goal of CoCo service: - L3-VPN service - On-demand private multi-domain, multi-point networks. - Connect laptops, VMs, storage, instruments, escience resources. - Each escience community group can easily setup their own private CoCo instance via web portal. Based on OpenFlow programmable network infrastructure.

20 Example CoCo Instance

21 Forwarding in CoCo CoCo OpenFlow application inserts flow forwarding entries. Forwarding based on MPLS label matching and forwarding. - Label stack with two MPLS labels. - Outer MPLS label used to identify egress PE switch. - Inner MPLS label used to identify CoCo instance. Adding and removing MPLS labels done at edges (PE).
