106-17 Telemetry Standards Chapter 28. This chapter defines the mechanisms and processes for managing RF links with the RF network. The RF network implements an Open Systems Interconnection model approach to data transmission, where data moves through the OSI stack from the application layer to the physical layer, from physical layer to physical layer through some transmission medium, then back up the stack to another application on the receiving side. For the most part, the RF network operates just like any other TCPIP network, where a message is created using a standard data management protocol, such as Simple Network Management Protocol is encapsulated at the transport layer to TCP or UDP and then is further encapsulated into an IP packet that contains the logical addressing and path routing determination. Where the RF network differs from the standard OSI model is in the data link and physical layers, where MACs have been modified to support transmission over RF links. The RF network manages communications at the data link and physical layers of the OSI model. This chapter focuses on the RF network with respect to managing the data link layer of the OSI model. The RF network is a multi-node network with a network layer control and data plane. The control plane for managing the RF link layer multiple access is described in this document. For information on the physical layer of the RF network, refer to Chapter 27. The RF networks control plane uses the existing ground network and adds RF connectivity to allow changes to RF transmission and capacity allocation in transceivers during missions. Radios need not establish direct bidirectional links with other transceivers in order to be part of the RF network. Rather, they are part of the network based on the principles and standards associated with normal IP routing protocols and need only support one or more paths to and from the overall RF network.
