Summary
Broadcast behaves differently than point-to-point communication. With broadcast communication, the number and identity of recipients is immaterial. A broadcast goes to everyone able to receive the broadcast. Broadcasts may be relayed for increased coverage.Broadcast is particularly useful for news, entertainment, and advertising to 1000s of users. It is also useful for service discovery, coordination, help-wanted, and requests for information. Publish and subscribe is practical for smaller distribution lists.
Consider limiting the length of broadcasted short messages. Details may be retrieved on demand. (cbb 8/06)
Subtopic: algorithms
Quote: with broadcast communication, anyone interested in a change can respond to it [»balzRM_1986] Quote: one EIES group defined three lines as the maximum length of a broadcasted message; recipients could access additional material [»hiltSR7_1985] Quote: use broadcast methods to turn mono-process into distributed programs [»stefM1_1987] Quote: broadcast is important for distributed systems for advertising needs and services and for coordinated problem solving [»cherDR4_1984] Quote: the router in the bulk-synchronous parallel model sends up to h messages for each component [»valiLG8_1990]
Subtopic: anycast communication
Quote: with high-bandwidth broadcast can perform a parallel nested-loops, relational join algorithm [»dewiDJ_1982]
Subtopic: using broadcast for news
Quote: use anycast resolvers to forward requests to the best server; application-layer; e.g., ServerLoad.wwwnews%cc.gatech.edu [»bhatS4_1997]
Subtopic: epidemic broadcast
Quote: CommunityInformationSystem broadcasts information via packet radio [»giffDK12_1985] Quote: Community Information Service broadcasts encrypted messages with a key identifier [»giffDK12_1985]
Subtopic: distributed system
Quote: epidemic algorithm for peer-to-peer broadcast; each node randomly forwards messages a limited number of times [»eugsPT5_2004] Quote: epidemic algorithms need to determine membership, network awareness, buffer management, and message filtering [»eugsPT5_2004]
Subtopic: coordination system
Quote: an Amoeba domain is an interconnected collection of local area networks; broadcasts to every machine in the domain but none outside; e.g., for locating a port [»taneAS12_1990]
Subtopic: problems with broadcast
Quote: Colab uses broadcast methods (object-oriented) to send same message to multiple machines [»stefM1_1987] Quote: Colab broadcasts changes with optimistic update (voice locks when needed) [»stefM1_1987] Quote: talking-out-loud (overhearing) helps colleagues orient their actions to a wider context; specific responses are not called for [»robiM1_2000]
Quote: membership is difficult for epidemic algorithms; e.g., broadcasting partial membership has problems with uniformity, adaptivity, and bootstrapping [»eugsPT5_2004] Quote: without global state must rule out broadcast since 'every actor' is ill-defined [»hewiC8_1977] Quote: broadcast is seldom used in ethernet because everyone must process it; too slow
