small, manageable packets, each wrapped with the essential http://pluto.ksi.edu/~cyh/cis370/ebook/ch03c.htm information needed to get it from its source to the correct destination. This lesson introduces the concept of packets as the basic building blocks of network data communications. http://support.motioneng.com/technology/synqnet/pkt_err_ctr.htm After this lesson, you will be able to: Define the term "packet," including its function and components. Describe the contents and function of each packet component: header, data, and how to trailer. Estimated lesson time: 30 minutes The Function of Packets in Network Communications Data usually exists as rather large files. However, networks cannot operate if computers put large amounts of data on the cable at the same time. As you see in Figure 3.5, a computer sending large amounts of data causes other computers to wait (increasing the packets on a frustration of the other users) while the data is being moved. This is not called "sharing"; it is called "monopolizing the network." There are two reasons why putting large chunks of data on the cable at one time slows down the network: Large amounts of data sent as one large unit tie up the network and make timely interaction and communications impossible because one computer is flooding the cable with data. The impact of retransmitting large units of data further multiplies network traffic. These effects are minimized when the large data units are reformatted into smaller packages for better management of error correction in transmission. This way, only a small section of data is affected, and, therefore, only a small amount of data must be retransmitted, making it relatively easy to recover from the error. Figure 3.5 Large continuous streams of data slow down the network In order for many users at once to transmit data quickly and easily across the network, the data must be broken into small, manageable chunks.
errors occured since startup?). Since communication over a SynqNet network is based upon the sending and receiving of packets, it is important to monitor the data integrity of the system. Packets must be checked to ensure that they are being sent/received properly and that the packets that are sent contain the right information. The Packet Error Counter increments by one for each invalid or missing packet. There are Packet Error Counters on the individual nodes and the controller to check packets on the upstream and downstream cycle. Unlike CRC Errors, packet errors are node-specific (i.e. Nodes only check their own packets and ignore all other packets). Node The Packet Error Counter on each node checks to make sure that it received all three of its packets that were sent from the controller during each downstream SynqNet cycle. Each downstream cycle, a node expects to receive a SYNQ, DEMAND, and CONTROL packet. The counter is reset to zero after a hardware reset or can be manually reset in Motion Console. The counter is an unsigned 8-bit value, and saturates at a maximum of 0xFF. Controller The controller also has a Packet Error Counter for each node (up to 32 of each). Their function is identical to the node counters except the controller expects to receive two packets (FEEDBACK and STATUS) from each node for every upstream SynqNet cycle. The controller has individual packet error counters for each node, which count the number of upstream packet errors from each node. The counter increments by one for each invalid or missing packet. The counter is reset to zero after a hardware reset or can be manually reset in Motion Console. The counter is an unsigned 8-bit value, and saturates at a maximum of 0xFF.
