2 Proliferation of Middleboxes 2/16 a router that manipulatees traffic rather than just forwarding it NAT rewrite IP address and TCP port fields to allow private addressing firewall inspect headers and data (deep packet inspection) to block unwanted traffic load balancer inspect headers and reroute packets to a different server to balance load in a cluster and more! See RFC 3234 current networks have a mix of routers (network layer), switches (link layer) and middleboxes (both layers), each with specialized hardware, software, management
3 SDN Data Plane Control Plane Software Defined Networking 3/16
4 Software Defined Networking 4/16 generalize the packet forwarding architecture: match-plus-action previously match only on destination address, action is only forward on an output port now, match on any fields in link layer, network layer, transport layer headers now, action can be forwarding, load balancing, rewrite (NAT), block (firewall), inspect (DPI), etc. control plane is logically centralized data plane uses a flow table pioneering work with OpenFlow
5 Key characteristics 5/16 flow-based forwarding: can use any of the fields in any header of any layer separation of data plane and control plane: data plane packet switches do match-plus-action forwarding, control plane manages the switch flow tables network control functions: control software runs on machines separate from the packet switches programmable network: can program the packet switches to execute many different functions: forwarding, load balancing, firewalling, etc.
6 Data Plane
7 Flow table 7/16 header field values: match incoming packets counters: count packets that have been matched actions: actions based on result of match essentially a programmable packet switch can be implemented efficiently with multiple flow tables, in hardware
8 Match-Plus-Action 8/16 match OpenFlow 1.0 packet matching fields cover three layers newest OpenFlow spec provides 41 values for matching action forwarding dropping modify field can act as a switch or a router or a middlebox
9 OpenFlow Examples: Simple Forwarding 9/16 s1 Flow Table Match Action Ingress Port = 1; IP Src = 10.3.*.*; IP Dst = 10.2.*.* Forward(4)... Will need similar tables for each packet switch
10 OpenFlow Examples: Load Balancing s2 Flow Table Match Action Ingress Port = 3; IP Dst = 10.1.*.* Forward(2) Ingress Port = 4; IP Dst = 10.1.*.* Forward(1)... Will need additional tables for each packet switch 10/16
11 OpenFlow Examples: Firewalling s2 Flow Table Match Action IP Src = 10.3.*.* IP Dst = Forward(3) IP Src = 10.3.*.* IP Dst = Forward(4)... In absence of other entries, no other traffic forwarded 11/16
12 Control Plane
13 SDN Data Plane Control Plane SDN Architecture controller maintains state of links, switches, hosts network control applications program network functions 13/16
14 SDN Controller logically centralized, but physically distributed among a set of 14/16
15 OpenFlow Protocol 15/16 messages from the controller to a switch configuration: query and set paramters modify-state: add/delete/modify nentries in flow table read-state: collect statistics and and counters send-packet: send a packet on a specified port messages from a switch to the controller flow-removed: flow table entry removed, due to timeout or modify-state message port-status: change in port status (e.g. up/down) packet-in: send packet that doesn t match any flow table entry to controller for processing and more...
