2.1 Title: Standard for Local and metropolitan area networks--Bridges and Bridged Networks Amendment: Stream Gates 4.2 Expected Date of submission of draft to the IEEE-SA for Initial Sponsor Ballot: 03/2017 4.3 Projected Completion Date for Submittal to RevCom: 10/2017 5.2.b. Scope of the project: This standard specifies procedures and managed objects for an bridge to perform frame counting, policing, and service class selection for a frame based on the particular Time Sensitive Networking data stream to which the frame belongs, and a synchronized cyclic time schedule. Policing functions include the detection and mitigation of misbehavior by other systems in a network, improving the robustness of that network. 5.3 Is the completion of this standard dependent upon the completion of another standard: No 5.5 Need for the Project: The development of standards for Time-Sensitive Networking (TSN) have shown that there exist no interoperable standards that enable a bridge to detect whether or not some systems in a TSN network are misbehaving. In particular, devices that exceed their allocated per-stream bandwidth can prevent the network from achieving the benefits of TSN for any or all streams, not just the misbehaving stream. 5.6 Stakeholders for the Standard: Developers, providers, and users of networking services and equipment for IoT (including industrial automation, automotive networking, smart grid) and of operating systems, hypervisors and orchestration systems for virtual machines. This includes software developers, networking IC developers, bridge and NIC vendors, and users.
