  As new networking paradigms emerge for different networking applications,
e.g., cyber-physical systems, and different services are handled under a
converged data link technology, e.g., Ethernet, certain applications with
mission critical traffic cannot coexist on the same physical networking
infrastructure using traditional Ethernet packet-switched networking protocols.
The IEEE 802.1Q Time Sensitive Networking (TSN) task group is developing
protocol standards to provide deterministic properties on Ethernet based
packet-switched networks. In particular, the IEEE 802.1Qcc, centralized
management and control, and the IEEE 802.1Qbv, Time-Aware Shaper, can be used
to manage and control scheduled traffic streams with periodic properties along
with best-effort traffic on the same network infrastructure. In this paper, we
investigate the effects of using the IEEE 802.1Qcc management protocol to
accurately and precisely configure TAS enabled switches (with transmission
windows governed by gate control lists (GCLs) with gate control entries (GCEs))
ensuring ultra-low latency, zero packet loss, and minimal jitter for scheduled
TSN traffic. We examine both a centralized network/distributed user model
(hybrid model) and a fully-distributed (decentralized) 802.1Qcc model on a
typical industrial control network with the goal of maximizing scheduled
traffic streams.
