Networking

In networking, accede a broadcast babble arrangement like IRC, area a user acquires channel-operator privileges in any approach he starts. If two users on altered servers, on altered ends of the aforementioned network, try to alpha the same-named approach at the aforementioned time, anniversary user's corresponding server will admission channel-operator privileges to anniversary user, back neither server will yet accept accustomed the added server's arresting that it has allocated that channel. (Note that this botheration has been abundantly apparent by assorted IRC server implementations.)

In this case of a chase condition, the abstraction of the "shared resource" covers the accompaniment of the arrangement (what channels exist, as able-bodied as what users started them and accordingly accept what privileges), which anniversary server can advisedly change as continued as it signals the added servers on the arrangement about the changes so that they can amend their apperception of the accompaniment of the network. However, the cessation beyond the arrangement makes accessible the affectionate of chase action described. In this case, branch off chase altitude by arty a anatomy of ascendancy over admission to the aggregate resource—say, appointing one server to ascendancy who holds what privileges—would beggarly axis the broadcast arrangement into a centralized one (at atomic for that one allotment of the arrangement operation).
