    摘要: A flexible slotted Aloha communication protocol for a burst-type communication network divides a communication channel into a series of time cycles, with each time cycle further divided into contiguous time slices of identical duration. All data transmissions in the network begin at the start of a time slice and continue for an integer number of time slices, with the identity of the transmitting terminal, the length of the transmission and error correction, being included within the first time slice of each data transmission. Communication terminals in the network transmit reservation requests to a network hub which receives the reservation requests and reserves reserved time slots each having a number of time slices which matches the length of the data transmission to be transmitted in the reserved time slot. The reserved time slot may include time slices in more than one time cycle. The communication protocol dynamically adjusts reservation parameters to match traffic load conditions on the channel and may reassign communication terminals from one channel to another in order to dynamically balance the load on the channels.

    摘要: A broadband communication system with improved latency is disclosed. The system employs acceleration of secure web-based communications over a satellite communication network. In accordance with aspects of the invention, secure protocol acceleration is employed such that required protocol signals transmitted from a computer employing a web browser may be intercepted by a remote terminal. To insure that the browser will continue transmitting data, the remote terminal generates required acknowledgment and security signals to continue the secure communication, which may then transmitted back to the computer. Meanwhile, the received protocol signals may be converted by the remote terminal for transmission through the satellite communications system in a format appropriate for that communication medium. Aspects of the invention further include a hub or similar device for communicating with the satellite communications system, and a secure connection between that device and the web server may be maintained by similarly simulating a continuous secure connection between the computer and the web server. Transmissions from the web server to the browser may be preformed in a similar manner. Further aspects of the invention related to distributed certificate sharing which may involve the generation of multiple certificates for the various links between the components employed in the communication system and the manual and/or automatic addition of a certificate authority.
