Demand paging protocol for sharing a number space among communicating entities

The demand paging protocol (DPP) for dynamic sharing of a number space among a group of communicating entities is described. DPP is a decentralized, multipoint protocol for local sharing. Some possible applications for DPP are presented. DPP is evaluated in terms of aspects of other protocols that perform similar functions. DPP is found to be fairer and likely to incur less overhead, especially given a worst-case scenario, than another multipoint approach proposed in IEEE 802.6 for distributed-queue dual-bus message identifier (DQDB MID) allocation. DPP is more decentralized and less deterministic than the MID allocation procedure. However, because DPP is not deterministic in its polling sequence, it imposes some additional requirements
