Python act_like_switch Examples

Example #1

File: pyretic_firewall.py Project: JaberBabaki/Fat-tree-topology-with-mininet

def main():
    not_allowed = none
    with open(policy_file, 'rb') as f:
        reader = csv.DictReader(f)
        for row in reader:
            not_allowed = not_allowed match(srcmac=MAC(row['mac_0']), dstmac=MAC(row['mac_1'])) match(srcmac=MAC(row['mac_1']), dstmac=MAC(row['mac_0']))

    allowed = ~not_allowed
    return  allowed>>act_like_switch()

Example #2

File: pyretic_wall.py Project: rakeshsukla53/Software-Defined-Networking-Mac-Load-RYU-Controller

def main():
    # start with a policy that doesn't match any packets
    not_allowed = none
    # and add traffic that isn't allowed
    with open(policy_file, 'rb') as f:
        reader = csv.DictReader(f)
        for row in reader:
            not_allowed = not_allowed | union([match(srcmac=MAC(row['mac_0']), dstmac=MAC(row['mac_1'])) | match(srcmac=MAC(row['mac_1']), dstmac=MAC(row['mac_0']))])

    # express allowed traffic in terms of not_allowed - hint use '~'
    allowed = ~not_allowed
#    allowed = if_(not_allowed, drop, passthrough)

    # and only send allowed traffic to the mac learning (act_like_switch) logic
    return allowed >> act_like_switch()

Example #3

    # start with a policy that doesn't match any packets
