5.2.7.2 Non-storing mode
If the device is the desired destination, it delivers the path and the source address therein to the next higher layer with the L2RLME-INTERMEDIATE-ADDR-LIST.indication primitive. The device also creates a new entry in the P2P path list Route iable of the MT where the Destination address is set to the address retrieved from the P2P SA field of the P2P-RQ IL the PSN is set to the value retrieved from the corresponding field in the IE, and the PQM value is set to the sum of the value of the PQM field and the LQM on the latest hop. The Intermediate address list is set to the inverted list of addresses found in the Intermediate Address List field. The device generates a P2P-RP lE and copies the Intermediate Address List field of the P2P-RQ IE into the corresponding field in the P2P-RP IE and sets the PSN to its own current PSN. The PQM Value is set to the value of the PQM recorded in th Ruui Table ntrv for the P2P path of interest. The P2P-RP IF is then carried forwarded to the source through the path indicated.
When the P2P-RP IE reaches the device with the address found in the P2P SA field, the device delivers the path and the source address therein to the next higher layer with the L2RLME-INTERMEDIATE-ADDR- LIST.indication primitive. The device also creates a new entry in the P2P path list Route Fable of the MT where the Destination address is set to the address retrieved from the P2P A field of the P2P-RP IE, and the PSN, the PQM value and the Intermediate Address List are set to the values retrieved from the corresponding fields in the IE.
5.3 L2R route maintenance
5.3.1 L2R US route maintenance
Change the sixth paragraph of 5.3.1 as indicated:
If a device misses does not receive consecutive l2rMaxMissedTcle TC lEs, from a neighbor, the corresponding entry in the NT is erased. Route Table entries in the Mesh Table (MT) using that neighbor are also erased.
5.3.2 L2R DS route maintenance
haiige the last paragraph of 5.3.2 as i,idicated:
If the L2R mesh is in non-storing mode, route entries Route Table entries (or list of reachable destinations in the NT) are not recorded by intermediate hops. The mesh root stores the entire path to the device identified by the SA found in the Intermediate Address List field in the Route Table. The route entries Route Table entries are updated if needed when the mesh root receives a new L2R Routing IE, RA IE, SLR IE or SRA IE. The device ma optionally delete a Route I able enir tr th N\ n trame c recjyd from the SA within a period of time determined by the implementer.
5.4.1 Unicast routing
5.4.1.1 Source routing
Change 5.4.1.1 as indicated:
Source routing is used in DS routing and non-on-demand P2P routing by the mesh root. It is also used by the source node in on-demand P2P muting: when non-storing mode is used, intermediate nodes are indicated.
If the frame is all incoming frame from the PIIY and if the frame pass the filtering at the MAC sublayer. the frame is delivered to the L2R sublayer. If the DA matches the device’s address, the frame is delivered to the next higher layer. If the DA does not match the device’s address, the frame is forwarded again.
If the L2R mesh is in non-storing mode, devices other than mesh root oniy store information about their neighbors but do not otherwise store DS routing information received with RA or SRA lEs. The mesh root stores all information received from the TC lEs and the RA lEs or SRA lEs. If on-demand P2P routing is enabled in non-storing mode, only the end to end source and destination devices of a P2P path store routing information. In either case, source routing is used. The path to the destination received from the IntermediateAddrList parameter of’ L2R-DATA.request primitive or retrieved from the Route Table entry is included in the Intermediate Addresses List of the L2R Routing IE or the SLR IE and data frames are routed on the path indicated. An L2R mesh working in non-storing mode is indicated by Storing Mode set to FALSE in the MT.
