New Features in JUNOS Release 10.1 for M Series, MX Series, and T Series Routers
The following features have been added to JUNOS Release 10.1. Following the
description is the title of the manual or manuals to consult for further information.
Class of Service
■
Intelligent oversubscription service support (MX Series routers with Trio
MPC/MIC interfaces)
—Arriving packets are assigned to one of two traffic classes
(control and best-effort) based on their header types and destination MAC address.
This allows for lower priority packets to be dropped more intelligently when
oversubscription occurs. Only packets mapped to queue 3 are marked as control
packets. Protocols such as telnet, FTP, and SSH that are mapped to queue 0 are
classified as best-effort. No configuration is necessary, but the queue assignments
can be altered with a multifield classifier.

■
CoS aspects of the MPC/MIC (MX Series routers with Trio MPC/MIC
interfaces)
—Cover all aspects of CoS configuration for this hardware combination.
Support includes shaping rates at the queue level, configurable bandwidth profiles
with percentages, dynamic bandwidth allocation among different services,
scheduler node scaling, and delay buffer allocation. To configure, include the
relevant statements at the
[edit class-of-service]
hierarchy level and apply them
if necessary at other hierarchy levels such as the
[edit interfaces]
hierarchy level.

■
Per-priority shaping (MX Series platforms with Trio MPC/MIC
interfaces)
—Enables you to configure a separate shaping rate for each of the
five priority levels so that higher priority services such as voice and video do not
starve lower priority services such as data. To configure, include the
shaping-rate-(excess | priority)-
level rate
