Abstract:
1. A method comprising: configuring a first transport tree within a transport network, wherein the first transport tree comprises a first root node, wherein the first transport tree is configured to transport a multipoint-to-multipoint datastream to a plurality of edge nodes, including first and second edge nodes, of the transport network through the first root node; configuring a second transport tree within the transport network, wherein the second transport tree comprises a second root node, wherein the second transport tree is configured to transport the multipoint-to-multipoint datastream to the plurality of edge nodes through the second root node; the first and second edge nodes receiving data of the multipoint-to-multipoint datastream from first and second data sources, respectively, which are external to the transport network; the first and second edge nodes determining the first root node is unavailable; the first edge node selecting the second transport tree in response to determining that the first root node is unavailable; and the second edge node selecting the second transport tree in response to determining that the first root node is unavailable.
