Juniper MX-MPC2-3D-Q Modular Port Concentrator

High-Performance Packet Forwarding Engine with Advanced Hierarchical QoS

The Juniper MX-MPC2-3D-Q is a high-performance Modular Port Concentrator (MPC) designed to deliver advanced packet forwarding, scalable traffic management, and modular interface flexibility for MX-Series 3D Universal Edge Routers. Built by Juniper Networks, this MPC module is compatible with MX240, MX480, and MX960 routers, providing powerful edge routing capabilities for service providers and enterprise networks.

Powered by dual Juniper Trio ASICs, the MX-MPC2-3D-Q delivers high-speed packet processing and hardware-accelerated services. The module supports up to 60 Gbps of full-duplex throughput, enabling reliable performance for demanding applications such as L3VPN, L2VPN, VPLS, and large-scale IPv4/IPv6 routing.

A key feature of the MX-MPC2-3D-Q is its advanced Hierarchical Quality of Service (HQoS) architecture. With support for up to 256,000 total queues and up to 128,000 egress queues, the module enables granular bandwidth allocation, traffic shaping, and service-level enforcement. This makes it particularly well suited for service provider networks that require per-subscriber or per-VLAN traffic management.

The module features a modular design with two MIC (Modular Interface Card) slots, allowing network operators to deploy different interface types such as 1GbE or 10GbE connectivity within a single MPC slot. This flexibility simplifies network expansion and supports diverse connectivity requirements across enterprise and carrier networks.

The MX-MPC2-3D-Q also offloads complex networking tasks - including firewall filtering, traffic policing, and J-Flow (NetFlow) monitoring - to the dedicated Trio ASICs. This hardware-based processing ensures that advanced services can run at wire-rate performance without impacting routing efficiency.

Designed for large-scale edge routing deployments, the module supports massive scaling with up to 256,000 MAC addresses and more than one million IPv4 routes when paired with compatible routing engines and switch control boards. Its Neo-ready architecture ensures compatibility with modern Junos environments and evolving network technologies.

With its high-performance Trio ASIC architecture, large-scale queuing capabilities, and modular interface support, the Juniper MX-MPC2-3D-Q provides a powerful and scalable solution for service provider edge networks, enterprise WAN infrastructure, and high-capacity routing platforms.

FAQs:

Q1. Does this MPC include physical ports?
No. The MX-MPC2-3D-Q is a carrier module. You must install MICs (Modular Interface Cards) into the two available slots to provide the physical connectivity (e.g., MIC-3D-20GE-SFP or MIC-3D-2XGE-XFP).

Q2. What is the difference between the "Q" and "EQ" versions?
The "Q" version supports up to 256K queues, which is sufficient for most high-density edge deployments. The "EQ" (Enhanced Queuing) version offers even deeper buffers and enhanced queuing features for extremely demanding service provider environments.

Q3. Is this MPC compatible with the MX104 or MX204?
No. This module is designed for the modular MX240, MX480, and MX960 chassis. The MX104 and MX204 utilize fixed or specialized form-factor line cards.

Q4. Does it support 100G interfaces?
While the MPC2 chassis bandwidth is rated at ~60 Gbps, it can support 100G MICs (like the MIC3-3D-1X100GE-CFP), but the total throughput will be rate-limited by the MPC's backplane capacity and SCB type.

Q5. Can I use this in an MX960 with standard SCB boards?
Yes, but to achieve the full performance and scaling capabilities of the Trio ASICs, it is highly recommended to use SCBE or SCBE2 switch control boards.
