1.2 General Packet Format

Figure 2.1 is an example of a General Packet format.

Figure 1.1 General Packet Format

Notes:

• There will be only one Packet Header for each message.

• All data in each packet will be sent in Big Endian byte order.

• Each bit is assigned by weight where bit 0 is the Least Significant Bit (LSB), bit 31 is the Most

Significant Bit (MSB) in a 32-bit word and bit 63 is the Most Significant Bit (MSB) in a 64-bit word.

• There will be one-to-one correspondence between the Data Header and the Data fields. That is to say, for each piece of data there will be exactly one Data Header unless the special provision of Block Data is used for the Size Type. In this case, an array could be sent using only one Data Header provided that an enumeration value was defined for that array type. See Section 3.2.2 Data Header Format – Operational for Block Data Transfers for details.

• There is no formal record structure. Data header/Data pairs can be sent at any time in any order provided that the correct packet type is indicated.

• The packet transmitted to the network will comply with the standard network protocol. The data contained in the packet will be in Big Endian Format; this includes the data packet header, data header, data element, and the checksum of the data contained within a packet.

• All systems receiving data via this standard need to be designed such that receiving applications:

1. Must be able to ignore, without ‘crashing’ or compromising other packet interfacing functions, packets from an unrecognized source system (the ‘Packet Source’ field in the header).

2. Must be able to ignore/skip data messages from unrecognized source systems without ‘crashing’ or compromising other packet interfacing functions. This is the ‘Data Source’ field found in every standard message data header.

3. Must be able to ignore/skip data elements that contain unrecognized signal types, device Ids, command, or control messages without ‘crashing’ or compromising other packet interfacing functions. This is the ‘Signal Type’, ‘Signal’, ‘Device ID’, ‘Command’, or ‘Control Message’ fields found in the standard message data headers.

4. Must be able to abort the interpretation of a SMF&P packet without ‘crashing’ or compromising other packet interfacing functions if a data error occurs such that a packet cannot be interpreted whether the error occurs in the packet header or within the data fields.

5. Must be able to ignore, without ‘crashing’ or compromising other packet interfacing functions, an unrecognized packet SMF&P type (the ‘Packet Type’ field in the header)

1.3.1 Packet Header Data

The Packet Header will consist of the following totaling to 36 bytes:

Data Data Size Description Time of Transmission 64 bit The time the data was actually put on the wire. * Time of Data 64 bit The time the data was collected from the sensors. * Day of Year 16 bit The day the data was collected.

Year 16 bit The year the data was collected.

Packet Type 8 bit An enumeration indicating the Packet Type of the data. Use the Packet Type Enumerations listed in Table 1.

Number of Data Elements 8 bit Total count of individual data elements in the message. In the case of Block Data, Block Data counts as 1 element.

Packet Source 16 bit An enumeration indicating the generator of the packet. Use the Source Type Enumerations listed in Table 2.

Unique ID Number 16 bit An integer number starting at zero and incremented for every

Standard Message generated. This number is a revolving count and rolls over after 65535. This will aid in determining redundant data packets.

Message Type 8 bit An enumeration identifying the type of message. Use the Navigation Message Type Enumerations listed in Table 9.

Version 8 bit The current revision of the Stdmsg.h file. Currently set to 6 Spare 32 bit Reserved for future use (RFFU)

1.4 Checksum Format

Figure 2.3 is an example of a Checksum format, the term MSB represents the Most Significant Bit and LSB represents the Least Significant Bit.

Checksum

Figure 1.3 Checksum Format

• The Checksum for the entire message includes the Packet Header, Data Headers, and Data fields, but excludes the Checksum itself.

• The Checksum is the 4 byte arithmetic sum, without carry over, of all the bytes in the message, excluding 4 bytes of the checksum field itself.

• The Checksum must be the last word of the data transmission.

• The Checksum is an unsigned 32-bit value.

2. OVERVIEW

2.1 Standard Message Packet Types

The Standard Message Format and Protocol (SMF&P) defines a method to transmit digital data on a network with information built within to indicate what the data is, its size, its origin, and if the data is valid.

Currently, there are seven types of Standard Message Packets. Refer to Table 1 Packet Type Enumerations.

Operational:

This is the primary Packet Type for Operational Data. Operational Data is any data collected from a sensor requiring transmission to another user or display.

Operational – Element Order Change:

This Packet Type is identical to the normal Operational Packet Type except for a different type.

The element order of the Standard Message is not fixed. Element additions and deletions are permitted. This mechanism provides a way to signal the end user that the normal packet order has changed.

Configuration:

This Packet Type allows a configuration change to be sent within a message. The receiving computer would update its parameters from the contents of this message.

Command:

This Packet Type provides the capability to send commands between two systems. An example would be to change the device currently reporting data or command a device to report status.

Report:

This Packet Type identifies a Report. This would be a response to a Report Request sent via the Command Packet Type.

Control:

This Packet Type provides the capability to transfer control to another station. New Integrated Bridge Systems (IBSs) require some sort of control transfer. Two computers must engage in a series of control requests to actively transfer control.

Status:

This Packet Type provides a mechanism to obtain status from devices that know about the status of the particular device. IBSs require device status to be displayed to the operators. For example, a computer that is directly connected to sensors will know the status of each sensor and therefore be able to be queried for that status by another computer.

2.2 Data Header Formats

2.2.1 Data Header Format – Operational

Figure 3.1 is an example of an Operational Data Header, the term MSB represents the Most Significant Bit and LSB represents the Least Significant Bit. There will be one 32-bit Data Header for each piece of data.

A second 32-bit word will be appended to the Data Header. Figure 3.2 is an example of an Operational Data Header for Block Data Transfers. Block Data is nothing more than a fancy term for an array or chunk of data. The receiver of the data is responsible for decoding the data.

3. ADDENDUM

3.1 Big Endian

A Big Endian machine stores data with the MSB first in the lowest memory address which is the address of the data. Since TCP defines the byte ordering for network data end-nodes must call a processor-specific convert utility (which would do nothing if the machine's native byte ordering is the same as TCP's). In a TCP/IP packet the first transmitted byte is the MSB.
