摘要： A method of encapsulating data packets for use in a distributed computer network is disclosed. The method includes providing a data packet for transmission over the distributed computer network, the data packet selected from one of a customer data packet and an OAM data packet; and encapsulating the data packet with a medium access control outer packet. The disclosed data packet handling method includes receiving a data packet from a customer facing data port, the customer facing data port within a network node of a computer network; performing medium access control (MAC) learning for the received packet; determining whether the data port is a MAC-in-MAC port; performing a packet mapping to a destination address based on a service provider destination address; and encapsulating the received data packet with a header associated with the service provider.

摘要： A particular method includes measuring port usage data related to each of a plurality of physical ports associated with a link aggregation group. A bandwidth requirement of a requested media stream is estimated and added to a traffic load at each of the plurality of physical ports to produce an estimated total traffic load of each of the plurality of physical ports. When the requested media stream includes non-video data, the requested media stream is sent to a destination device via a physical port that selected in accordance with a static bandwidth allocation. When the requested media stream includes video data, the requested media stream is sent to the destination device via a least loaded physical port that is dynamically identified based on the estimated traffic loads of each of the plurality of physical ports.
