摘要： A system and method are provided for implementing performance improvements in a multicast protocol for networks that support incipient congestion indications via packet marking in instances of packet loss in the network during time-correlated blockages by providing indications in the physical (PHY) layer. A receiver rate calculation is adjusted so that a loss due to blockage is ignored completely and only packets marked using an Explicit Congestion Notification (ECN) packet marking protocol are treated as losses. Receiver rates are modified based on ECN principles to ignore losses. A NORM receiver rate equation may remain substantially unchanged while a sender is enabled to keep sending at a higher data rate, even in instances of blockage in support of higher system throughputs without defining a completely new receiver rate equation. Time-correlated blockages are not treated as losses.
