Abstract

Methods and apparatus for dynamic packet mapping. A method is provided for mapping metric data to produce a decodable packet associated with a channel. The method includes obtaining a channel identifier associated with metric data, determining an available buffer from a plurality of buffers based on the channel identifier, writing the metric data to the available buffer, detecting when a decodable packet is formed in a selected buffer of the plurality of buffers, and outputting the decodable packet from the selected buffer. An apparatus includes a plurality of buffers and mapping logic that is configured to obtain a channel identifier associated with metric data, determine an available buffer based on the channel identifier, write the metric data to the available buffer, detect when a decodable packet is formed in a selected buffer, and output the decodable packet from the selected buffer.
