INTRODUCTION

General Overview

The Radio Link Layer provides the following functions:

• Negotiation of packet filters and Quality of Service (QoS) for IP packets.

• Mapping of Reservations to Streams.

• Segmentation, reassembly, retransmission (if needed) and duplicate detection of higher layer packets,

• Multiplexing of application Streams.

• Identify the Protocol Stack associated with this Route during Route initialization.

• Determine whether Route Protocol packets for transmission should be delivered to the Packet Consolidation Protocol of this Route or the Inter-Route Tunneling Protocol of this or another Route.

The Radio Link Layer uses one instance of the Radio Link Protocol for each Stream, the QoS Management Protocol, the Stream Protocol, and the Route Protocol to provide these functions.
