A computing device may include a memory and a processor cooperating with the memory to generate data to correct errors in transmission of packets to a client device based upon a ratio of a first bandwidth in which to transfer content of a buffer and a second bandwidth in which to transfer the generated data, the packets to transfer the content and the generated data to the client device via a channel. The processor may further adjust the ratio based upon a parameter of the channel, and send the content of the buffer and the generated data via packets and through the channel to the client device based on the adjusted ratio.

Packet classification using fingerprint hash table

A key is descriptive of a data packet, and a fingerprint hash function is applied to such a key to generate a fixed length fingerprint of the key. An index value is determined based on a portion of the fingerprint. A hash table could be populated by storing in a memory, at a memory location associated with the index value: a remainder of the fingerprint other than the portion of the fingerprint that was used to determine the index value, to indicate that data packets consistent with the key are to be handled in accordance with packet handling metadata. During packet processing, if a memory location associated with an index value stores a remainder of the fingerprint other than the portion of the fingerprint that was used to determine the index value, a data packet is handled according to packet handling metadata associated with the fingerprint.
