Juniper Cloud Metro

---

Metro Ethernet is an Ethernet transport network (shown in Figure 1) that provides point-to-point or multipoint connectivity services over a metropolitan area network (MAN). Ethernet originated as a LAN technology, and became a replacement for low-speed WAN technologies. 

Business, residential, and mobile subscribers select Ethernet services from service providers because of its cost effectiveness, flexibility, and simplicity. Service providers use Metro Ethernet to:

• Interconnect business offices or data centres. Metro Ethernet can connect two sites or hundreds of sites.

• Connect residential subscribers or businesses to the Internet.

• Provide connectivity to public or private cloud data canters.

• Provide wholesale mobile backhaul services.

• Provide multicast delivery used by business customers for video conferencing, and used by residential subscribers for IPTV and video applications.

Ethernet business services and direct public cloud access have been growing at double-digit rates for the past several years, and there’s no end in sight. 

Offering a lower cost per bit and bandwidth scalability, Ethernet’s popularity is also being fueled by unprecedented network traffic growth. Video usage, mobility, the shift from TDM to IP networking, cloud services, smart cities, and the Internet of Things (IoT) are the primary generators of that growth. 

Ethernet services have been able to proliferate to meet these needs in part thanks to the MEF Forum’s CE 2.0 specifications. These standards enable providers to grow their businesses by interconnecting their performance-assured services across local, regional, national, and international networks.

In turn, Ethernet business services in the metro are expected to grow the fastest of all the network market segments in both the number of connection endpoints and network traffic volumes supported. Revenues are expected to reach $65 billion globally by 2020 and account for the proliferation of data centers within metro areas for IP video caching, Network Functions Virtualization (NFV) deployments, and cloud services.

Cloud Exchange Networks

With cloud exchange networks , you can augment Ethernet resources by sharing them with multiple customers. Instead of committing bandwidth to each customer, you can dynamically allocate bandwidth as needed enabling you to maximize network utilization and reduce infrastructure costs.

We can help you address these challenges with our MEF CE 2.0-certified business and direct public cloud access Ethernet solutions. Deliver your services with:

• Scalability—Decoupling physical topology for transport and service layers enables you to scale your networks to tens of thousands or even hundreds of thousands of nodes.

• Resiliency—Enabling MPLS on your network significantly decreases the risk of Layer 2 loops and broadcast storms. Multihomed connectivity between CPE and access nodes and between access nodes and aggregation nodes creates a loop-free, resilient network.

• Flexibility—Support for Layer 2 and Layer 3 services such as MEF E-Line, E-LAN, E-Tree, E-Access, VPLS, IP, traditional IP VPNs, and emerging IP EVPNs means you can use a single converged infrastructure to profitably serve multiple customer use cases. Among them: L2/L3 business access; direct Internet access (DIA); direct public cloud access; last-mile fiber access (FTTx); aggregation; and mobile haul (front, mid, and back).

• Operational efficiency—Junos OS includes embedded scripting tools and APIs for automating routine and repetitive tasks. Easy integration with any OSS/BSS and zero touch deployment (ZTD) dramatically reduce the complexity of extending MPLS in the access layer to lower OpEx.

Features: 

Metro Ethernet over Seamless MPLS

You can run Ethernet services over your MPLS network from the core to the access segment. It provides service flexibility and scaling of the MAN where you can terminate Metro Ethernet services at any point in the network.

Metro Ethernet over Optical Transport Networks

Juniper Networks offers many single-platform, packet-based solutions that include either fixed (built-in)  or modular (line card) options to deploy optical (DWDM) services from the same platform. This enables longer reach transport between network elements, or traffic hand-off to an optical network (e.g., reconfigurable optical add/drop multiplexer (ROADM)).

ACX Series Universal Access Routers

These compact, power-efficient, and MEF CE 2.0–certified Carrier Ethernet access and aggregation routers offer rich Layer 2, Layer 3, and MPLS features, programmability, and Ethernet OAM support.

MX Series Universal 3D Routers

These routers offer high performance for converged residential, mobile, and Metro Ethernet services on a single platform.
