Abstract: Explicit congestion notification (ECN) data that is utilized in a core portion of a cellular communication network has known issues associated with a first use scenario and an infrequent use scenario. A probe comprising probe data and a data structure for storing certain ECN data can be transmitted in order to mitigate these issues. Transmitting the probe in response to a communication session being established with a device of a network can mitigate the first use issue. Transmitting the probe in response to expiration of a probe timer in connection with a network traffic idle period can mitigate the infrequent use scenario.

Abstract: Methods and systems are described to store and forward multicast traffic. The method includes receiving a request to add a first node to a membership tree including a first plurality of nodes associated with a multicast group, identifying a second node in the first plurality of nodes, communicating a node identifier that identifies the first node over a network to the second node where the node identifier is stored at the second node to add the first node to the membership tree where the node identifier is stored in the membership tree to enable the second node to forward multicast traffic to the first node, and where the first and second nodes are separated from each other by at least one other node of the first plurality of node. The first node can be associated with a multicast member that has been added to the multicast group. Other embodiments are disclosed.
