1. A system, comprising:
one or more processors configured to:
determine a network allocation map in a time division multiple access (TDMA) cycle, the network allocation map comprising a plurality of TDMA slot reservations that are assignable corresponding nodes from among a plurality of nodes in a vehicle communication network;
determine assignments for each of the nodes of the plurality of nodes in the vehicle communication network, the assignments comprising assignment to low latency traffic slot reservations or bulk traffic slot reservations, wherein the low latency traffic slot reservations have a first latency guarantee of 500 microseconds or less, and the bulk traffic slot reservations have a second latency guarantee of 40 milliseconds or less;
provide the network allocation map to a first node and a second node from among the plurality of nodes,
the first node assigned to a low latency traffic slot reservation having a first latency guarantee that satisfies a first threshold, and
the second node assigned to a bulk traffic slot reservation having a second latency guarantee that satisfies a second threshold; and
cause one or more messages to be transmitted by the plurality of nodes in accordance with the low latency traffic slot reservations and the bulk traffic slot reservation.
