The application relates to a method of handling a group communication in a communications network, comprising the steps of agreeing and arranging participating clients of a group; establishing a communication session for directed exchanging of streamed media between the participating clients, coordinating communication resources, especially the direction of exchanging of streamed media, i.e. re-assigning a communication resource to a client when this clients has requested this communication resource, where the clients are symmetrically organized as peers in the communication network, i.e. there is no distinguished (centralized) client but a distributed system of peers (P, P, P), where a peer to peer network among the participating clients is established for coordinating the direction of exchanging of streamed media by electing at least one participating peer (P, P, P) of said group of participating peers (P, P, P) as a source peer; and piping the streamed media originated by the at least one participating peer (P, P, P) to the participating peers via the peer to peer network, and coordinating the mutual exclusive communication resources by initiating an election by a request ('), and resolving the concurrent request (&#x2032;) fair and alive by a distributed election algorithm between the peers using the peer to peer network. The invention also relates to a computer software product, a network client, and a communication system therefor.

Provided is a method for a hypermedia communication system including: the steps of generating a hypermedia by presenting the hypermedia in a hypermedia description at a hypermedia server; requesting the hypermedia at a hypermedia client; deploying the hypermedia description from the server to the hypermedia client; and presenting the hypermedia by translating the hypermedia description. The hypermedia description includes expression means for a reference from an atemporal hypermedia object to a referred hypermedia object. The method also includes the steps of generating, requesting, deploying, and presenting hypermedia, uniformly, using a hypermedia description including further expression means for a reference from a temporal hypermedia object to a referred hypermedia object.
