#10: Add pseudo code ------------------------------------------+--------------------------------- Reporter: suresh.krishnan@ericsson.com | Owner: Suresh Krishnan Type: defect | Status: new Priority: major | Milestone: Component: simple | Version: Severity: Active WG Document | Resolution: Keywords: | ------------------------------------------+--------------------------------- Comment(by suresh.krishnan@ericsson.com): I propose to add the following text to a new section called "Pseudocode for Simple DNA" to resolve this issue. The pseudocode is written in an imaginary language and any resemblance to real programming languages is unintentional. /* Link up indication received on INTERFACE */ /* Start Simple DNA process */ /* Mark All Addresses as deprecated */ Configured_Address_List=Get_Address_List(INTERFACE); foreach Configured_Address in Configured_Address_List { if (Get_Address_State(Configured_Address)!=AS_TENTATIVE) { Set_Address_State(Configured_Address,AS_DEPRECATED); } } /* Mark all routers' NC entries as STALE to speed up */ /* acquisition of new router if link change has occurred */ foreach Router_Address in DEFAULT_ROUTER_LIST { NCEntry=Get_Neighbor_Cache_Entry(Router_Address); Set_Neighbor_Cache_Entry_State(NCEntry,NCS_STALE); } /* Thread A : Send Router Solicitation */ RS_Target_Address=FF02::2; RS_Source_Address=Get_Any_Link_Local_Address(INTERFACE); Send_Router_Solicitation(RS_Source_Address,RS_Target_Address); /* Thread B : Send Neighbor Solicitation(s) */ Previously_Known_Router_List=Get_Router_List_from_SDAT(); NS_Source_Address=Get_Any_Link_Local_Address(INTERFACE); foreach Router_Address in Previously_Known_Router_List { if (Get_Any_Valid_Address_from_SDAT(Router_Address)) { Send_Neighbor_Solicitation(NS_Source_Address,Router_Address); } } /* Thread C : Response collection */ /* Received Router Advertisement processing */ /* Only for RAs received as response to DNA RSs */ L3_Source=Get_L3_Source(RECEIVED_MESSAGE); L2_Source=Get_L2_Source(RECEIVED_MESSAGE); SDAT_Entry_List=Get_Entries_from_SDAT_L2L3(L3_Source,L2_Source)); foreach SDAT_Entry in SDAT_Entry_List { if (Exists_PIO(RECEIVED_MESSAGE,Get_Prefix(SDAT_Entry))) { /* Address is operable. Configure on Interface */ /* Rejoin solicited-node multicast group for address */ } else { /* If address is configured on interface, remove it */ /* This could be because of a NA arriving before RA */ } } /* Mark router as reachable */ NCEntry=Get_Neighbor_Cache_Entry(L3_Source); if (NCEntry is not NULL) { Set_Neighbor_Cache_Entry_State(NCEntry,NCS_REACHABLE); } else { Create_Neighbor_Cache_Entry(L3_Source,NCS_REACHABLE); } /* Ignore further NAs from this router */ Add_Router_to_NA_Ignore_List(L3_Source); /* Received Neighbor Advertisement processing */ /* Only for NAs received as response to DNA NSs */ L3_Source=Get_L3_Source(RECEIVED_MESSAGE); L2_Source=Get_L2_Source(RECEIVED_MESSAGE); if (Is_Router_on_NA_Ignore_List(L3_Source)) { /* Ignore message and wait for next message */ continue; } SDAT_Entry_List=Get_Entries_from_SDAT_L2L3(L3_Source,L2_Source)); foreach SDAT_Entry in SDAT_Entry_List { /* Address is operable. Configure on Interface */ } -- Ticket URL: <http://rsync.tools.ietf.org/wg/dna/trac/ticket/10#comment:1> dna <http://tools.ietf.org/dna/> _______________________________________________ dna mailing list dna@ietf.org https://www.ietf.org/mailman/listinfo/dna
