Asynchronous Layered Coding (ALC) Protocol Instantiation

UDP Usage Guidelines

“…o Receiver-driven congestion control, which does not require a receiver to send explicit UDP control messages for congestion control (e.g., [RFC3738], [RFC5775]). Instead, the sender distributes the data across multiple IP multicast groups (e.g., using a set of {S,G} channels).…”

Forward Error Correction (FEC) Framework

“…The proposed solution is also based on IPsec/ESP. However, the difference with respect to [RFC5775] relies on the management of IPsec Security Associations (SAs) and corresponding Security Policy Database (SPD) entries, since NORM requires a second set of SAs and SPD entries to be defined to protect unicast feedback from receivers.…”

“…Note that the IPsec/ESP requirement profiles outlined in [RFC5775] and [RFC5740] are commonly available on many potential hosts. They can form the basis of a secure mode of operation.…”

Use of Timed Efficient Stream Loss-Tolerant Authentication (TESLA) in the Asynchronous Layered Coding (ALC) and NACK-Oriented Reliable Multicast (NORM) Protocols

“…For more information on ALC and NORM, please refer to [RFC5775], [RFC5651], and [RFC5740], respectively. For more information on FLUTE, please refer to [RMT-FLUTE].…”

“…This is the case with ALC [RFC5775] and NORM [RFC5740], two Content Delivery Protocols (CDPs) designed to transfer objects (e.g., files) reliably between a session's sender and several receivers. The NORM protocol is based on bidirectional transmissions.…”
