Abstract: A method is performed at a source node in a network of nodes configured with a link state protocol, and in which at least some of the nodes are enabled for multiprotocol label switching (MPLS). The node discovers and stores a link state topology representing the nodes of the network, links between the nodes, path-costs for the links, and whether each link is enabled or not enabled for MPLS. The node determines one or more shortest paths from the source node to a destination node among the nodes based on traversing the link state topology and, while the node traverses the link state topology, detects whether each shortest path supports or does not support MPLS end-to-end dataplane continuity. The node programs an IP dataplane with each shortest path, and programs an MPLS dataplane with ones of the one or more shortest paths that support the end-to-end MPLS continuity.

Abstract: It is proposed an example for mapping between a signal field and a data field used in a wireless local area network (LAN) system supporting a plurality of resource units (RUs). If a second channel (e.g., a 20 MHz band) is nullified and thus a physical layer protocol data unit (PPDU) is not transmitted, a signal field transmitted through a first channel may include allocation information regarding all data channels, and a signal field transmitted through the first channel is preferably duplicated on a third channel. In this case, a signal field transmitted through a fourth channel may include only allocation information for a data field corresponding to the fourth channel.

Abstract: A technique for implementing AP-local dynamic switching involves Layer 2 switching. This may be accomplished by providing data associated with wireless stations to an AP sufficient to enable the AP to determine whether traffic from a particular wireless station should be locally switched. Alternatively, the wireless station may be able to determine whether to locally switch traffic based upon the traffic itself. For example, it may be desirable to AP-locally switch voice traffic to avoid latency, which is particularly detrimental to voice transmissions such as voice-over-IP. Traffic that is not to be switched locally is Layer 2 tunneled upstream.
