CoS on 10-port 10-Gigabit Oversubscribed Ethernet PICs Overview
The 10-port 10-Gigabit Oversubscribed Ethernet (OSE) Type 4 PIC supports intelligent handling of oversubscribed traffic in applications, such as data centers and dense-core uplinks. The 10-port 10-Gigabit OSE PIC supports line rate operation for five 10-Gigabit Ethernet ports from each port group or a total WAN bandwidth of 100 Gbps with Packet Forwarding Engine bandwidth of 50 Gbps.
The class-of-service (CoS) configuration for the 10-port 10-Gigabit OSE PICs are supported on Juniper Networks TX Matrix and TX Matrix Plus and Juniper Networks T640 and T1600 Core Routers. The 10-port 10-Gigabit OSE PICs support behavior aggregate (BA) and fixed classification, weighted round-robin scheduling with two queue priorities (low and strict-high), committed and peak information rate shaping on a per-queue basis, and excess information rate configuration for allocation of excess bandwidth.
To configure these features, include the corresponding statements at the [edit class-of-service] hierarchy level.
