Table 1 Standardized priorities services
From: TACRM: trust access control and resource management mechanism in fog computing
Arranged classes | Priority level | Example services |
|---|---|---|
HP: high priority | 1 | Mission critical delay sensitive signalling (e.g., MC-PTT signalling, MC video signalling) Mission critical user plane push to talk voice (e.g., MCPTT) IMS signalling |
2 | Mission critical video user plane Conversational voice Non-mission-critical user plane push to talk voice | |
3 | V2X messages Real time gaming, V2X messages Electricity distribution—medium voltage Process automation—monitoring | |
MP: medium priority | 4 | Conversational video (live streaming) |
5 | Non-conversational video (buffered streaming) | |
6 | Mission critical data Video (buffered streaming) TCP-based (e.g., www, e-mail, chat, ftp, p2p file sharing, progressive video, etc.) | |
LP: low priority | 7 | V2X messages Low latency eMBB applications (TCP/UDP-based) Augmented reality Voice, video (live streaming) Interactive gaming |
8 | Video (buffered streaming) TCP-based (e.g., www, e-mail, chat, ftp, p2p file sharing, progressive video, etc.) | |
