Managing Line Resources
The first part of this chapter provides an overview of line resource reservation for
ST2 traffic on Bay Networks routers.
Later sections explain
• Starting the LRM
•
Configuring the LRM
•
Disabling Line Resource Management
About Line Resource Management Services
Emerging realtime multicast applications for digitized voice and video (such as
multimedia conferencing and virtual reality) require a level of consistent network
service that routers cannot meet using simple first-in-first-out (FIFO) queuing
mechanisms. The existing best-effort delivery service of IP networks, where
variable queuing delays and data loss due to congestion are acceptable, is not
sufficient.
Resource reservation protocols such as Stream Protocol 2 (ST2) address the
requirements of delay-sensitive applications by distributing information among
routers to achieve a guaranteed Quality of Service (QoS) for specific packet
streams (flows).
The Line Resource Manager allows you to use guaranteed QoS to both meet the
demands of realtime applications and maintain bandwidth for other traffic.
Note: Before you can enable the LRM, you must first configure IP and the
ST2 agent on a circuit. See Configuring IP Multicasting Services.
