Statement of Work

Ethernet-based Deterministic Network design and Implementation

I. BACKGROUND

The Advanced Network Technology Division (ANTD) at the National Institute of Standards and Technology (NIST) is developing a deterministic network for wide area measurement in power grid monitoring systems. With the proliferation of Ethernet-based networks and widening Phasor Measurement Unit (PMU) installations, future PMU characteristics will require synchronous data delivery with low latency, high reliability, and minimum jitter. In addition, keeping up with the ever increasing integration of multiple sub-networks to cope with the massive number of PMU devices, as well as other sensor and actuators, will require the support of high-speed deterministic network such as TT-Ethernet.

II. PURPOSE & OBJECTIVES:

The purpose of this acquisition is to procure contractor services in support of ethernet-based deterministic/time triggered network design and implementation. The objective is to develop a testbed that demonstrates the reliability and low latency of time triggered networks.

III. SCOPE OF WORK:

The Contractor shall expand the communication networking aspects of the NIST combined grid communication testbed by developing a time triggered network based on two existing protocols, namely; Time –Triggered-Ethernet (TT-E) and Time Triggered Control Area Network (TT- CAN). This work shall include designing a gateway mechanism that can achieve timing and synchronization between the TT-E and TT-CAN protocols. The Contractor shall develop and evaluate the performance of the expanded testbed by exploiting its important features, such as reliability and latency for synchrophasor communications.

This requirement shall expand upon a previously developed combined grid testbed system; please see NIST sponsored publication: H. Gharavi and B. Hu, “Synchrophasor Sensor Networks for Grid Communication and Protection,” Proceedings of the IEEE, Vol. 105, No. 7, pp. 1408-1428, May 2017 for further information.

IV. SPECIFIC TASKS

The Contractor shall be responsible for project oversight, equipment, administration, and technical execution of this contract. The Contractor shall deliver a fully functional time-triggered communication network testbed based on the following specific tasks:

1. Review detailed specifications of TT-E and TT-CAN according to the SAE AS6802 and ISO 11898-4:2004 standards and then design a network architecture that uses TT-E as its backbone network for communication with the TT-CAN network via a gateway.

2. Develop a simulation-based network model of the TT-E and TT-CAN. The initial TT-E network set up shall operate in real-time using randomly generated data including different types of data such as TT-E messages, rate constrain messages, and best effort messages. The task shall also include the development of a fault tolerance model using redundant network switches.

3. Implement integrated hardware in the loop testbed that consists of two TT-E hardware switches with four end-systems, where three of the end systems shall be interfaced to a PMU and the fourth shall be connected to a Phasor Data Collector (PDC). To do this, the contractor shall also design a gateway node for interworking between TT-E and TT-CAN.

4. Test and demonstrate the functionality of the testbed in real-time using multiple PMU devices and measuring the performance of the integrated TT-E and TT-CAN networks in terms of required bandwidth, reliability, and latency, as well as testing the network resiliency performance using the fault tolerance model specified in Task-2. The complete design shall include gateway nodes that connect the TT-CAN as a subnetwork. The integrated TT-E and TT-CAN networks shall be fully operational in real-time where different types of messages can communicate with each other synchronously with low jitter and high reliability. Also, the contractor shall verify the impact of the fault tolerance model (task 2) towards ensuring network resiliency.
