Abstract
A congestion notification element for indicating a congestion status of a mesh node may include at least one field specifying a mesh destination for which an intra-mesh congestion control is to be applied. This may allow for forwarding data frames on paths that share some links but not the bottleneck link with a path that is congestion controlled, which has not been possible with currently specified congestion notification techniques.
Claims18
A congestion notification element for indicating a congestion status of a mesh node in a mesh network, the congestion notification element comprising:
- at least one field specifying a mesh destination for applying an intra-mesh congestion control.
A congestion control notification frame, Comprising:
- at least one congestion notification element, each congestion notification element comprising:
- at least one field specifying a mesh destination for applying an intra-mesh congestion control.
A method of controlling congestion in a mesh network, the method comprising:
- receiving at a receiving mesh node from a transmitting mesh node at least one congestion control notification frame including at least one congestion notification element;
- reading at least one transmitter mesh node address of said at least one congestion control notification frame as a next hop address;
- reading at least one destination mesh node address of said at least one congestion notification element, said destination mesh node address being an individual address or a broadcast address;
- and
- reading at least one congestion notification expiration timer of said at least one congestion notification element.
A mesh node in a mesh network comprising non-transitory computer-readable media storing instructions executable by a processor to:
- receive from a transmitting mesh node at least one congestion control notification frame including at least one congestion notification element;
- read at least one transmitter mesh node address of said at least one congestion control notification frame as a next hop address;
- read at least one destination mesh node address of said at least one congestion notification element, said destination mesh node address being an individual address or a broadcast address;
- and
- read at least one congestion notification expiration timer of said at least one congestion notification element.
