Inferred key frames for fast initiation of video coding sessions
A video coding system may initiate coding of a new coding session with reference to an “inferred key frame” that is known both to an encoder and a decoder before a coding session begins. The inferred key frame need not be transmitted between the encoder and decoder via the channel. Instead, the inferred key frame may be stored locally at the encoder and the decoder. Frames coded at the onset of a video coding session may be coded with reference to the inferred key frame, which increases the likelihood a decoder will receive a frame it can decode properly and accelerate the rate at which the decoder generates recovered video data. Inferred key frames may be used as prediction references to recover from transmission errors. |

Reliable transport layer protocol in low performance 8-bit microcontrollers
A reliable communication protocol RUDP is provided to transfer data between two systems connected in a network. Working over the unreliable UDP transport layer protocol, the RUDP protocol adds an acknowledging mechanism to otherwise unreliable UDP packets. Contrary to the TCP transport layer protocol, which establishes a connection before any data transfer, the RUDP is used to transfer short amounts of information or messages, so a connectionless communication is used. In a connectionless context the complexity of the encoding-decoding algorithm and the amount of memory consumed by the protocol is reduced. Such characteristics makes the RUDP protocol suitable for its implementation in systems with limited memory and speed, like low processing power 8-bit microcontrollers. Furthermore, by programming the RUDP protocol over the UDP protocol, its implementation in a personal computer can be made with common programming tools. |

Stream-based data deduplication with cache synchronization
Stream-based data deduplication is provided in a multi-tenant shared infrastructure but without requiring “paired” endpoints having synchronized data dictionaries. Data objects processed by the dedupe functionality are treated as objects that can be fetched as needed. As such, a decoding peer does not need to maintain a symmetric library for the origin. Rather, if the peer does not have the chunks in cache that it needs, it follows a conventional content delivery network procedure to retrieve them. In this way, if dictionaries between pairs of sending and receiving peers are out-of-sync, relevant sections are then re-synchronized on-demand. The approach does not require that libraries maintained at a particular pair of sender and receiving peers are the same. Rather, the technique enables a peer, in effect, to “backfill” its dictionary on-the-fly. On-the-wire compression techniques are provided to reduce the amount of data transmitted between the peers. |

Pipelined egress packet modifier
An egress packet modifier includes a script parser and a pipeline of processing stages. Rather than performing egress modifications using a processor that fetches and decodes and executes instructions in a classic processor fashion, and rather than storing a packet in memory and reading it out and modifying it and writing it back, the packet modifier pipeline processes the packet by passing parts of the packet through the pipeline.

Bulk data transport in a network
A network is configured to utilize available bandwidth to conduct bulk data transfers without substantially affecting the successful transmission of time-sensitive traffic in the network. In order to avoid this interference, the packets carrying data for bulk data transfers are associated with a low priority class such that the routers of the network will preferentially drop these packets over packets associated with the normal traffic of the network. As such, when the normal traffic peaks or there are link or equipment failures, the normal traffic is preferentially transmitted over the bulk-transfer traffic and thus the bulk-transfer traffic dynamically adapts to changes in the available bandwidth of the network. Further, to reduce the impact of dropped packets for the bulk-transfer traffic, the packets are encoded at or near the source component using a loss-resistant transport protocol so that the dropped packets can be reproduced at a downstream link. |

Thereafter, a formation treatment or an initial charge treatment is performed to precipitate lead so that the carbon mixture-coated layer and the negative plate are connected and integrated, at least in a part of a respective interfacial surface thereof, by the precipitated lead. |
