Juniper Networks MX-series Ethernet Services Routers
- Features & Benefits
- Performance at scale - New Dense Port Concentrators (DPC) cards combine high port density with a distributed architecture and on-board processing.
- Advanced QoS - Superior QoS at the interface level, enabling providers to ensure services receive the appropriate level of quality regardless of traffic conditions.
- Service flexibility - Leverages the JUNOS operating system.
This router establishes a new industry standard for Carrier Ethernet capacity, density and performance. The first in a series of Juniper platforms optimized for emerging Ethernet network architectures and services, the MX-series is purpose built for the most demanding carrier applications. The MX-series leverages the JUNOS operating system to enable carriers to seamlessly and cost-effectively deploy Ethernet and accelerate their next-generation network deployments. By combining a best-in-class hardware platform with the reliability and service flexibility of JUNOS, the MX-series delivers a combination of features and capabilities previously unattainable in Carrier Ethernet deployments.
The MX960 platform is the industry's largest-capacity Carrier Ethernet platform, with up to 960 gigabits per second (Gbps) of switching and routing capacity. It enables reduced costs, more revenue per platform and the ability to scale to protect customers' investments. Offering efficient support of high-density interfaces and high-capacity switching throughput, the MX960 supports a wide range of business and residential applications and services, including high-speed transport and VPN services, next-generation broadband multiplay services and high-volume Internet data center internetworking.
DPCs provide multiple physical interfaces and Packet Forwarding Engines on a single board that installs in a slot in the Juniper Networks MX-series Ethernet Services Router. A DPC receives incoming packets from the network and sends outgoing packets to the network. The Packet Forwarding Engines on a DPC are equipped with purpose-built application-specific integrated circuits (ASICs) that perform packet processing and forwarding. Each Packet Forwarding Engine consists of one I-chip for Layer 3 processing and one Layer 2 network processor.
The MX-series Ethernet Services Routers have three models of Dense Port Concentrators: DPC-R, DPCE-X, and DPCE-Q.
The DCP-X builds upon the Juniper Networks leadership position in providing high-performance networking hardware and software by extending the JUNOS operating system to include traditional Layer 2 switching features such as Spanning Tree as well as more recent Ethernet standards developments including Operation, Administration, and Maintenance (OAM). The MX-series combined with the DPC-X Layer 2 switching cards provide a wide range of MPLS and Ethernet functionality for cost-effective Layer 2 aggregation.
The DPC-X cards are designed specifically for applications that include:
- Distributed and centralized Central Office (CO) Ethernet aggregation: DPC-X cards can be used for pure Layer 2 Ethernet aggregation, for VLAN-based services with the ability to enable higher-value Layer 2 and VPLS and inter-autonomous system (AS) VPLS at no incremental cost.
- Metro Ethernet aggregation: DPC-X cards can be used as a combined Layer 2 and Layer 2.5 aggregation switch with MPLS control plane functionality to push such advanced capabilities further into the metro networks.
DPC-R and DPCE-R
In addition to the Layer 2 switching and MPLS features offered on the DPC-X cards, the DPC-R cards provide a full suite of layer routing protocols and packet processing capabilities.
The DPCE-Q cards provide enhanced queuing capabilities with support of up to 64,000 individual queues.
- 4 level hierarchical WRR
- 4 levels of per-VLAN queue priority
- Priority propagation
- Drop Statistics Per <VLAN, Color, Queue>
- Changeable allocation of schedulers per port (8,000 scheduler nodes with 8 queues each or 16,000 nodes with 4 queues each)
Features and Benefits
With advanced services and applications such as IPTV, VoIP and VPLS driving a more comprehensive set of sophisticated requirements, Juniper Networks has purpose built its Carrier Ethernet portfolio to address customer needs.
The portfolio offers:
Performance at Scale
New Dense Port Concentrators (DPC) cards, available on the MX-series, combine high port density with a distributed architecture and on-board processing, ensuring that performance scales with the addition of interfaces.
Advanced Quality of Service (QoS)
The MX-series features superior QoS at the interface level, enabling providers to ensure services receive the appropriate level of quality regardless of traffic conditions. This advanced capability lets providers offer a variety of Layer 2 and Layer 3 services-such as VLAN/transparent LAN, L2/L3 VPNs, Voice over IP and Video over IP-over Ethernet, with the ability to provide guaranteed SLAs.
Juniper is an industry leader in both IP/MPLS and VPLS. Its Carrier Ethernet portfolio leverages the JUNOS operating system that powers more than 27,000 Juniper M- and T-Series routers currently deployed in hundreds of service provider networks worldwide. JUNOS gives the MX960 feature richness, stability and service breadth not typically found in Carrier Ethernet platforms.
Simple, Non-disruptive Deployment
Utilizing the same JUNOS operating system that the world's largest service providers have deployed and relied upon for years, Juniper's Carrier Ethernet portfolio will enable service providers to immediately take advantage of the latest Ethernet technology without the cost and risks associated with introducing a new operating system to the network. A customer's familiarity, knowledge and integration of JUNOS in existing back-office systems can drive down capital expenditures while allowing rapid roll out of Ethernet-access networks and services.
Building upon these customer requirements, the MX960 provides up to twelve 40 Gbps slots in a single chassis and supports Juniper's new DPC cards, allowing customers to take advantage of unprecedented port density–up to 480 Gigabit Ethernet ports and 48 ports of 10 Gigabit Ethernet per system.
The distributed intelligence and packet processing of the MX-series and DPC cards are powered by the I-chip, Juniper's next-generation packet forwarding engine technology. By increasing scalability, packet performance and enhancing Ethernet-centric quality of service features, the MX-series will enable carriers to increase the number of services and customers supported per platform without negatively impacting performance. This increases service service flexibility and can also drive down both capital and operational expenses.
