2 Problem with Internet Infrastructure? Routing, management, mobility management, access control, VPNs, Feature Operating System Feature Million of lines of source code RFCs Specialized Packet Forwarding Hardware Billions of gates Bloated Power Hungry Vertically integrated, complex, closed, proprietary Not suitable for experimental ideas Not good for network owners & users; Not good for researchers.
3 Problem: No Abstractions for Control Plane Addition of a new function to the network Highly complex distributed system problem Networks too difficult to program and to reason about no good abstractions and interfaces Distributed Network Functions Router/Switch/Appliance Router/Switch/Appliance State Distribution Mechanism Router/Switch/Appliance Not good for even network vendors 3

16 Major Change in Paradigm No longer designing distributed control protocols Now just defining a centralized control function Configuration = Function(view) This spells the end for distributed protocols Easier to write, reason about, maintain,. Beginning of the software era of networking Rate of change, nature of standards, different culture, etc.

18 Pmargin Fmargin Why Does Verizon Care? Software defined network enables inexpensive feature insertion for new services and revenue uplift. Stu Networking Summit ARPU(PMO) $ Unacceptably high cost escalation results in a non-sustainable business case. The cost of PMO needs to be matched to the characteristics of revenue growth to support consistent margin. Target FMO costs Cost of PMO The cost of transition must not be prohibitive t Using COTS hardware following mass market cost curves lowers equipment expenditures Confidential and proprietary materials for authorized Verizon personnel and outside agencies only.

30 Time to engage and help shape this important revolution in networking
31 Important Questions Is the networking problem real? How does OpenFlow/SDN help? Are there any proof points? Is SDN just a cool idea or is it more fundamental? How can I experiment with OpenFlow/SDN What is next?
32 Enterprise Networking Enterprise network operators want.. Firewall and access control Delegate management to departments Share data network with VoIP network Lots of VLANs that stretch across buildings By-passing bottlenecks/check points for specific applications Host web services with load balancing Easy guest wireless access with security And more How do they do it today? 32

36 NETWORKING AND SERVER VIRTUALIZATION! The hidden headaches of moving to private cloud Guido ~3-6x increase in networking related trouble tickets per month after moving to private cloud computing model! Source: team estimates based on interviews across 8 enterprise and university network professionals in planning, pilots or production with private cloud architectures proprietary and confidential! 36
37 Imagine You re a Hot-Shot Programmer/Researcher And want to create a new service with real users Using Amazon EC2/S3, for example, you can allocate Computing Resources Storages But you cannot create a customized network: topology, BW, security, routing,. You cannot ask a cloud provider for a (virtual) network of your own and program it? 37
38 Confused User Poorly managed network due to lack of knowledge More devices, more complexity Home Network More players rely on Home Net Want to reach users with new, better and faster services Want to use home network for reducing costs (e.g., smartmeter, femtocell BS) Disconnection WAN 38

58 The Future of Networking, The Past of Protocols Scott Shenker, UC Berkeley Open Networking Summit, October
59 Software-Defined Networking SDN clearly has advantages over status quo But is SDN the right solution? Scott s talk: Not what SDN is, but why SDN is
60 Key to Internet Success: Layers Applications built on Reliable (or unreliable) transport built on Best-effort global packet delivery built on Best-effort local packet delivery built on Physical transfer of bits
61 Layers are Great Abstractions Layers only deal with the data plane We have no powerful control plane abstractions! How do we find those abstractions? Define our problem, and then decompose it.
62 The Network Control Problem Compute the configuration of each physical device E.g., Forwarding tables, ACLs, Operate without communication guarantees Operate within given network-level protocol Only people who love complexity would find this a reasonable request
63 From Requirements to Abstractions 1. Operate without communication guarantees Need an abstraction for distributed state 2. Compute the configuration of each physical device Need an abstraction that simplifies configuration 3. Operate within given network-level protocol Need an abstraction for general forwarding model
64 1. Distributed State Abstraction Shield mechanisms from vagaries of distributed state While allowing access to this state Natural abstraction: global network view Annotated network graph provided through an API Control mechanism is now program using API No longer a distributed protocol, now just a graph algorithm E.g. Use Dijkstra rather than Bellman-Ford
65 Network Software Traditional Defined Switches Control Network and/or Mechanisms Routers (SDN) e.g. routing, access control Control Program Global Network View Distributed algorithm running between neighbors Network OS
66 2. Specification Abstraction Control program should express desired behavior It should not be responsible for implementing that behavior on physical network infrastructure Natural abstraction: simplified model of network Simple model only enough detail to specify goals This is network virtualization
67 Simple Example: Access Control Abstract Network Model Global Network View
68 Software Defined Network Abstract Network Model Network Control Virtualization Program Global Network View Network OS
69 3. Forwarding Abstraction Control plane needs flexible forwarding model Abstraction should not constrain control program Should support whatever forwarding behaviors needed It should hide details of underlying hardware Crucial for evolving beyond vendor-specific solutions
70 OpenFlow Interface to Forwarding Abstraction Routing Network OS If header = x, send to port 4 If header = y, overwrite header with z, send to ports 5,6 If header =?, send to me Flow Table
71 Forwarding Primitives <Match, Action> Match arbitrary bits in headers: Header Data Match on any header, or new header Allows any flow granularity Action Match: 1000x01xx x Forward to port(s), drop, send to controller Overwrite header with mask, push or pop Forward at specific bit-rate
