Abstract
A network element connects over a network to a network node via a member link of a Multi-Chassis—Link Aggregation Link Group (MC-LAG), and further connects, using inter-peer ports, to peer network elements coupled to the network node via other MC-LAG member links. A processor of the network element is configured to receive from the network first packets destined to the network node, to receive via the inter-peer ports information indicative of second packets received from the network by the peer network elements that are destined to the network node, to select at least some of the first packets for transmission at an egress rate that jointly with egress rates of the peer network elements does not exceed a predefined MC-LAG maximal rate, based on the first packets and the information, and to transmit the selected first packets to the network node at the egress rate.
