Wildcards are applied to * firewall decision to optimize flows in the switch, ensuring least number * of flows per firewall rule. So, if a particular field is not "ANY" (i.e. * not wildcarded) in a higher priority rule, then if a lower priority rule * matches the packet and wildcards it, it can't be wildcarded in the * switch's flow entry, because otherwise some packets matching the higher * priority rule might escape the firewall. The reason for keeping different * two different wildcards is that if a field is not wildcarded in a higher * priority allow rule, the same field shouldn't be wildcarded for packets * matching the lower priority deny rule (non-wildcarded fields in higher * priority rules override the wildcarding of those fields in lower priority * rules of the opposite type). So, to ensure that wildcards are * appropriately set for different types of rules (allow vs. deny), separate * wildcards are maintained.

Roles are hard state on the switch and * we can't query it so we need to make sure that we have consistent states * on the switches. Whenever we send a role request to the set of connected * switches we need to make sure that we've sent the request to all of them * before we process the next change request. If a new switch connects, we * need to send it the current role and need to make sure that the current * role doesn't change while we are doing it. We achieve this by synchronizing * all these actions on Controller.roleChanger * On the receive side: we need to make sure that we receive a reply for each * request we send and that the reply is consistent with the request we sent. * We'd also like to send the role request to the switch asynchronously in a * separate thread so we don't block the REST API or other callers. * * There are potential ways to relax these synchronization requirements: * - "Generation ID" for each role request. However, this would be most useful * if it were global for the whole cluster * - Regularly resend the controller's current role. Don't know whether this * might have adverse effects on the switch. * * Caveats: * - No way to know if another controller (not in our controller cluster) * sends MASTER requests to connected switches. Then we would drop to * slave role without knowing it. Could regularly resend the current role. * Ideally the switch would notify us if it demoted us. What happens if * the other controller also regularly resends the same role request? * Or if the health check determines that * a controller is dead but the controller is still talking to switches (maybe * just its health check failed) and resending the master role request.... * We could try to detect if a switch demoted us to slave even if we think * we are master (error messages on packet outs, e.g., when sending LLDPs) * * * The general model of Role Request handling is as follows: * * - All role request messages are handled by this class. Class Controller * submits a role change request and the request gets queued. submitRequest * takes a Collection of switches to which to send the request. We make a copy * of this list. * - A thread takes these change requests from the queue and sends them to * all the switches (using our copy of the switch list). * - The OFSwitchImpl sends the request over the wire and puts the request * into a queue of pending request (storing xid and role). We start a timeout * to make sure we eventually receive a reply from the switch. We use a single * timeout for each request submitted using submitRequest() * - After the timeout triggers we go over the list of switches again and * check that a response has been received (by checking the head of the * OFSwitchImpl's queue of pending requests) * - We handle requests and timeouts in the same thread. We use a priority queue * to schedule them so we are guaranteed that they are processed in * the same order as they are submitted. If a request times out we drop * the connection to this switch. * - Since we decouple submission of role change requests and actually sending * them we cannot check a received role reply against the controller's current * role because the controller's current role could have changed again. * - Receiving Role Reply messages is handled by OFChannelHandler and * OFSwitchImpl directly. The OFSwitchImpl checks if the received request * is as expected (xid and role match the head of the pending queue in * OFSwitchImpl). If so * the switch updates its role. Otherwise the connection is dropped. If this * is the first reply, the SWITCH_SUPPORTS_NX_ROLE attribute is set. * Next, we call addSwitch(), removeSwitch() to update the list of active * switches if appropriate. * - If we receive an Error indicating that roles are not supported by the * switch, we set the SWITCH_SUPPORTS_NX_ROLE to false. We keep the * switch connection alive while in MASTER and EQUAL role. * (TODO: is this the right behavior for EQUAL??). If the role changes to * SLAVE the switch connection is dropped (remember: only if the switch * doesn't support role requests) * The expected behavior is that the switch will probably try to reconnect * repeatedly (with some sort of exponential backoff), but after a while * will give-up and move on to the next controller-IP configured on the * switch. This is the serial failover mechanism from OpenFlow spec v1.0. * * New switch connection: * - Switch handshake is done without sending any role request messages. * - After handshake completes, switch is added to the list of connected switches * and we send the first role request message if role * requests are enabled. If roles are disabled automatically promote switch to * active switch list and clear FlowTable. * - When we receive the first reply we proceed as above. In addition, if * the role request is for MASTER we wipe the flow table. We do not wipe * the flow table if the switch connected while role supported was disabled * on the controller. * */ public class RoleChanger { // FIXME: Upon closer inspection DelayQueue seems to be somewhat broken. // We are required to implement a compareTo based on getDelay() and // getDelay() must return the remaining delay, thus it needs to use the // current time.

Notes: 1. The circuit pusher currently only creates circuit with two IP end points 2. Prior to sending restAPI requests to the circuit pusher, the specified end points must already been known to the controller (i.e., already have sent packets on the network, easy way to assure this is to do a ping (to any target) from the two hosts. 3. The current supported command syntax format is: a) circuitpusher.py --controller={IP}:{rest port} --type ip --src {IP} --dst {IP} --add --name {circuit-name} adds a new circuit between src and dst devices Currently ip circuit is supported. ARP is automatically supported. Currently a simple circuit record storage is provided in a text file circuits.json in the working directory. The file is not protected and does not clean itself between controller restarts. The file is needed for correct operation and the user should make sure deleting the file when floodlight controller is restarted. b) circuitpusher.py --controller={IP}:{rest port} --delete --name {circuit-name} deletes a created circuit (as recorded in circuits.json) using the previously given name @author kcwang """ import os import sys import subprocess import json import argparse import io import time # parse circuit options.

To prove that point, this directory includes a number of useful utilities as examples of what can do with this extensibility. UTILITIES: -------------------------- graphDeps.py and graphTopo.py Read the module dependencies (graphDeps.py) or the topology from the REST API and output it in the 'dot' format used by the popular graphviz (www.graphviz.org) package so that they can be visualized. Example usage: ./graphTopo.py $hostname # generate .dot file dot -Tpdf -o $hostname.pdf $hostname.dot # convert to PDF open $hostname.pdf # open to view topology packetStreamerClientExample.py Example client for the packet streamer server in floodlight. Allows you to intercept packets from floodlight's packet_in processing chain and read them. floodlight-0.90/setup-eclipse.sh0000775000175000017500000000232212041336206017366 0ustar jamespagejamespage#!/bin/bash d=$(dirname $0) MAIN_CLASS=$1 LIBRARIES=$2 [ "${MAIN_CLASS}" ] || { echo "Run 'ant eclipse' to generate Eclipse project files"; exit 1; } cat >$d/.project < floodlight org.eclipse.jdt.core.javabuilder org.eclipse.jdt.core.javanature EOF cat >$d/.classpath < EOF ( IFS=":" for l in ${LIBRARIES}; do cat >>$d/.classpath < EOF done ) cat >>$d/.classpath < EOF
