A REED # MUST process incoming Advertisements and perform a one-way frame-counter # synchronization with at least 3 neighboring Routers. When Router receives # unicast MLE Link Request from REED, it replies with MLE Link Accept. # # Test Topology: # ------------- # Router_15 - Leader # ... / \ # Router_n Router_1(DUT) # | # REED(DUT) # # DUT Types: # ---------- # Router # REED class Cert_5_2_7_REEDSynchronization_Base(thread_cert.TestCase): USE_MESSAGE_FACTORY = False TOPOLOGY = { LEADER: { 'name': 'LEADER', 'mode': 'rdn', }, DUT_ROUTER1: { 'name': 'ROUTER_1', 'mode': 'rdn', }, ROUTER2: { 'name': 'ROUTER_2', 'mode': 'rdn', }, 4: { 'name': 'ROUTER_3', 'mode': 'rdn', }, 5: { 'name': 'ROUTER_4', 'mode': 'rdn', }, 6: { 'name': 'ROUTER_5', 'mode': 'rdn', }, 7: { 'name': 'ROUTER_6', 'mode': 'rdn', }, 8: { 'name': 'ROUTER_7', 'mode': 'rdn', }, 9: { 'name': 'ROUTER_8', 'mode': 'rdn', }, 10: { 'name': 'ROUTER_9', 'mode': 'rdn', }, 11: { 'name': 'ROUTER_10', 'mode': 'rdn', }, 12: { 'name': 'ROUTER_11', 'mode': 'rdn', }, 13: { 'name': 'ROUTER_12', 'mode': 'rdn', }, 14: { 'name': 'ROUTER_13', 'mode': 'rdn', }, 15: { 'name': 'ROUTER_14', 'mode': 'rdn', }, 16: { 'name': 'ROUTER_15', 'mode': 'rdn', }, DUT_REED: { 'name': 'REED', 'mode': 'rdn', }, } DUT = 0 def test(self): self.nodes[LEADER].start() self.simulator.go(config.LEADER_STARTUP_DELAY) self.assertEqual(self.nodes[LEADER].get_state(), 'leader') for i in range(2, 17): self.nodes[i].start() self.simulator.go(config.ROUTER_STARTUP_DELAY) for i in range(2, 17): self.assertEqual(self.nodes[i].get_state(), 'router') # Avoid DUT_REED attach to DUT_ROUTER1. if self.DUT == DUT_REED: self.nodes[DUT_REED].\ add_allowlist(self.nodes[DUT_ROUTER1].get_addr64(), config.RSSI['LINK_QULITY_1']) if self.DUT == DUT_ROUTER1: self.nodes[DUT_REED].\ add_allowlist(self.nodes[DUT_ROUTER1].get_addr64(), config.RSSI['LINK_QULITY_1']) self.nodes[DUT_REED].add_allowlist(self.nodes[ROUTER2].get_addr64()) self.nodes[DUT_REED].enable_allowlist() self.nodes[DUT_REED].start() self.simulator.go(config.MAX_ADVERTISEMENT_INTERVAL) self.assertEqual(self.nodes[DUT_REED].get_state(), 'child') self.simulator.go(config.MAX_ADVERTISEMENT_INTERVAL) def verify(self, pv): pkts = pv.pkts pv.summary.show() LEADER = pv.vars['LEADER'] ROUTER_1 = pv.vars['ROUTER_1'] REED = pv.vars['REED'] # Step 1: Verify topology is formed correctly except REED. for i in range(1, 16): with pkts.save_index(): pv.verify_attached('ROUTER_%d' % i) # Step 2: REED attaches to the network and MUST NOT attempt to become # an active router by sending an Address Solicit Request pv.verify_attached('REED') pkts.filter_wpan_src64(REED).\ filter_coap_request(ADDR_SOL_URI).\ filter(lambda p: { NL_MAC_EXTENDED_ADDRESS_TLV, NL_STATUS_TLV } <= set(p.coap.tlv.type) ).\ must_not_next() # Step 3: REED sends a unicast Link Request message to at lease 3 Routers # # The Link Request Message MUST contain the following TLVs: # - Challenge TLV # - Leader Data TLV # - Source Address TLV # - Version TLV if self.DUT == DUT_REED: for i in range(0, MLE_MIN_LINKS): pkts.filter_wpan_src64(REED).\ filter_mle_cmd(MLE_LINK_REQUEST).\ filter(lambda p: { CHALLENGE_TLV, LEADER_DATA_TLV, SOURCE_ADDRESS_TLV, VERSION_TLV } <= set(p.mle.tlv.type) ).\ must_next() # Step 4: Router_1 sends Link Accept message # The following TLVs MUST be present in the Link Accept message: # - Link-layer Frame Counter TLV # - Source Address TLV # - Response TLV # - Version TLV # - MLE Frame Counter TLV (optional) # # The recipient does not make any change to its local state and # MUST NOT reply with a Link Accept And Request message. if self.DUT == DUT_ROUTER1: pkts.filter_wpan_dst64(REED).\ filter_wpan_src64(ROUTER_1).\ filter_mle_cmd(MLE_LINK_ACCEPT).\ filter(lambda p: { LINK_LAYER_FRAME_COUNTER_TLV, RESPONSE_TLV, SOURCE_ADDRESS_TLV, VERSION_TLV } <= set(p.mle.tlv.type) ).\ must_next() pkts.filter_wpan_src64(REED).\ filter_mle_cmd(MLE_LINK_ACCEPT_AND_REQUEST).\ must_not_next() class Cert_5_2_7_REEDSynchronization_REED(Cert_5_2_7_REEDSynchronization_Base): DUT = DUT_REED class Cert_5_2_7_REEDSynchronization_ROUTER(Cert_5_2_7_REEDSynchronization_Base): DUT = DUT_ROUTER1 if __name__ == '__main__': unittest.main()
