A network device may include first logic configured to count data units passing through the network device and to produce a counter value. The network device may include second logic configured to receive the counter value when an indicator is present, and to store the counter value. The network device may include third logic configured to sample the second logic, to receive the counter value, and to operate on the counter value to produce a result.

Described are computer-based methods and apparatuses, including computer program products, for input queued content switching using a playlist. A retrieval sequence is generated using a plurality of content requests based on content location information. A first portion of content is requested to be queued at a first content source, and a second portion of content is requested to be queued at a second content source. A content stream of the first portion and the second portion of content is generated using the retrieval sequence. The generating includes selecting the first portion of content from a queue associated with the first content source and transferring the first portion of content to an output buffer, then terminating transfer of the first portion of content and initiating transfer of the second portion of content from a queue associated with the second content source. The portion of content in the output buffer is transmitted to a client device.

A system receives a set of datagrams and forms frames based on the datagrams, where at least one of the frames includes data associated with multiple ones of the datagrams. The system writes the frames to memory to form superframes in the memory, where each of the superframes includes multiple ones of frames. The system reads the superframes from the memory, recreates the datagrams based on the superframes, and outputs the datagrams.
