DLEP

This document defines a new Data Item for the Dynamic Link Exchange Protocol (DLEP) to support traffic classification. Traffic classification information identifies traffic flows based on frame/packet content such as a destination address. The Data Item is defined in an extensible and reusable fashion. Its use will be mandated in other documents defining specific DLEP extensions. This document also introduces DLEP Sub-Data Items and defines two new Sub-Data Items to support Diffserv and Ethernet traffic classification.

This document defines new Dynamic Link Exchange Protocol (DLEP) Data Items that are used to support credit-based flow control. Credit window flow control is used to regulate when data may be sent to an associated virtual or physical queue. These Data Items are extensible and reusable.

This document also defines new messages that support credit window flow control.

This document defines an extension to the Dynamic Link Exchange Protocol (DLEP) that enables a Diffserv aware credit window scheme for destination-specific and shared flow control.

This document defines an extension to the Dynamic Link Exchange Protocol (DLEP) that enables an Ethernet IEEE 802.1Q aware credit window scheme for destination-specific and shared flow control.

This document defines an extension to the Dynamic Link Exchange Protocol (DLEP) to provide the range of latency that can be experienced on a link.

The Dynamic Link Exchange Protocol (DLEP) is a protocol for modems to advertise the status of wireless links between reachable destinations to attached routers. The core specification of the protocol (RFC 8175) assumes that every modem in the radio network has an attached DLEP router and requires that the Media Access Control (MAC) address of the DLEP interface on the attached router be used to identify the destination in the network, for purposes of reporting the state and quality of the link to that destination.

This document describes a DLEP extension that allows modems that do not meet the strict requirement above to use DLEP to describe link availability and quality to one or more destinations reachable beyond a device on the Layer 2 domain.

This document defines an extension to the Dynamic Link Exchange Protocol (DLEP) that enables a modem to use DLEP messages to pause and resume data traffic coming from its peer router.

This document defines an extension to the Dynamic Link Exchange Protocol (DLEP) that enables the reporting and control of multi-hop forwarding by DLEP-capable modems.

When routing devices rely on modems to effect communications over wireless links, they need timely and accurate knowledge of the characteristics of the link (speed, state, etc.) in order to make routing decisions. In mobile or other environments where these characteristics change frequently, manual configurations or the inference of state through routing or transport protocols does not allow the router to make the best decisions. This document introduces a new protocol called the Dynamic Link Exchange Protocol (DLEP), which provides a bidirectional, event-driven communication channel between the router and the modem to facilitate communication of changing link characteristics.
