Abstract:

A system for reliable multicast distribution includes a primary content engine and a backup content engine sender. The primary content engine sender sends out a multicast message of content to selected content engine receivers. The sender waits for negative acknowledgments from the selected content engine receivers declaring that content was not received. If a negative acknowledgment is received, the sender resends the multicast message a predetermined number of times. If the content is still not received after the number of multicast passes is exhausted, the sender sends out unicast messages to those receivers still requesting content. If the primary sender does not respond to a negative acknowledgment, the receiver sends a second negative acknowledgment to the backup multicast sender. The backup responds with the data requested in the negative acknowledgment and so is able to begin data distribution at the point where the primary sender left off without maintaining synchronicity with the primary sender.

Abstract:

A system and a method are disclosed for matching users of an accommodation management system to an event and prompting the matched users to make an accommodation listing available during the event. In an embodiment, the accommodation management system detects an event occurring in a geographic region. Responsive to detecting the event, the accommodation management system identifies users registered in the geographic region that are exhibiting low hosting activity. The accommodation management system compares the event to accommodation listings on a wish list associated with each retrieved user. Responsive to a successful match between the event and a retrieved user's wish list, the accommodation management system outputs a prompt to the user recommending that the user make a listing for an accommodation available during the event.

Abstract:

A system and a method are disclosed for satisfying a curriculum during nomadic travel. In an embodiment, an accommodation management system receives, from a client device, information describing a desired curriculum scope and a time period. The system optimizes a curriculum based on subjects mapped from the curriculum scope and the time period. The system maps the curriculum to destinations and determines a set of geographic regions including the destinations. The system determines a set of geographic regions including the destinations. For each geographic region, the system retrieves, from a listing database, listing available in the geographic region during a subset of the time period. The system ranks the retrieved listings for each geographic region based on the destinations and transmits, for display on a user interface at the client device, an accommodation recommendation including listings in one or more of the geographic regions.

Abstract:

A system and a method are disclosed for prompting a user of an accommodation management system to host an accommodation during an event. In an embodiment, the accommodation management system detects an event occurring in a geographic region. The accommodation management system identifies a user in the geographic region and determines an estimated hosting value of the user hosting an accommodation during the event. Responsive to determining the estimated hosting value, the accommodation management system identifies an accommodation listing on a wish list associated with the user based on the estimated hosting value and a reservation criterion of the listing. The accommodation management system outputs a prompt to the user recommending that the user hosts an accommodation during the event based on the identified listing.

Abstract:

A system and a method are disclosed for augmenting a required curriculum of an individual in a nomadic group. The system retrieves, from a client device, a request for an accommodation recommendation from the nomadic group, which includes an individual with a required curriculum. The system maps the curriculum to destinations in a destination database and determines a set of geographic regions including the destinations. The system optimizes an accommodation recommendation based on available listings in the geographic regions and geographic locations of the destinations and transmits, for display on a user interface at the client device, a user interface comprising the accommodation recommendation.
