Abstract

Systems and methods for providing SRV node selection are provided. The method may include using an entry node to submit a query message in selected fields of a Device Attribute Information Element in L2ME protocol. The entry node may require an advanced service. The entry node may not be aware which node of the plurality of nodes is the node selected for supporting the advanced service on the network. The selected fields may include vendor specific fields. In response to the query message, the method may further include determining which of the plurality of nodes can be selected for supporting the advanced service on the network. The method may further include determining whether there is a one the plurality of nodes which has been selected for supporting the advanced service on the network.
