Residential users utilize either built-in Wi-Fi or a discrete access point to provide wireless access to home clients such as smartphones, printers, game consoles, and other appliances. Clients of the home network: The devices in the home that use the broadband service. These include home computers, set-top boxes, printers, game consoles, DVRs, media players, and video cameras, to name a few. This list continues to expand. The home network connects to the access network.

Home and Access Network

Many broadband access technologies exist for broadband access including digital subscriber line DSL , cable access, and passive optical networking PON. The key function in the access network is the multiplexing and demultiplexing of multiple subscribers hundreds or thousands through the aggregation network and to the broadband edge for service delivery. The subscriber accesses the network via an access protocol. Transport mechanisms assist in establishing sessions between subscribers and services. Transport mechanisms enable several key functions of the broadband network to include establishment of the physical link and session, authentication, authorization, identification of the user, and network monitoring.

Sessions can then be used to manage subscriber connection to the network. In the access network, each subscriber has a discrete circuit, or connection, into the broadband network. At some point, all of these subscribers must converge onto a single service aggregation point a single device or a cluster of devices for transport to and from the services to which they are subscribed. The traffic must be aggregated onto a single transport while maintaining separation between subscriber traffic. There are a couple of choices for VLAN design.

This is often referred to as the 1: The aggregation network in this solution architecture assumes a 1: This design enables optimal subscriber scale on the broadband edge. There are various methods of provisioning types of VLANs for aggregating user traffic. Because of the wide array of services and bandwidth requirements of modern multiplay networks, we recommend the implementation of hybrid VLAN H-VLAN architecture to optimize real-time media and Internet traffic. The various access nodes are often aggregated into fewer connections for optimal transport to the broadband edge.

Aggregation can be done in several ways. A dual-homed topology can also be used, where each access node is redundantly connected into an aggregation node; the aggregation node itself is connected as a full or partial mesh, with multiple connections existing between each of the aggregation routers. Finally, a ring topology can be employed.

Components Overview

In a ring topology, the aggregation nodes are connected redundantly to each other in a ring, forming a right and left redundancy path. In this design, access nodes are aggregated directly onto optical rings. The recommended topology is driven by cost and need for resiliency, although the ring topology offers the best mix of redundancy and cost optimization, providing redundant paths for traffic and fewer interconnections.

  7. A focus on simplicity should drive any effective aggregation network design, as this network tier serves only to aggregate subscribers to the edge network. The Juniper Networks Broadband Edge solution accommodates all of these aggregation options. The BNGs also manage addressing and service attachment, and handle the multiplexing and demultiplexing of traffic to and from the individual subscriber. An important area of design consideration is the placement of BNGs in the network; they should be placed in a way that optimizes service activation and attachment. In a hybrid model, BNGs are placed close to the subscriber and in the POP, depending on subscriber density and bandwidth requirements from the serving office.

    The recommended edge architecture is the hybrid model, as it enables the best mix of flexibility and service impact and can be tailored to fit both the service footprint and the traffic load easier than either the distributed or centralized models. Each of these models has trade-offs. The distributed BNG model increases device count as more BNGs are required, although the cost can be mitigated somewhat because the distributed BNG serves as a pre-aggregation router, minimizing interconnections into the aggregation layer.

    The centralized BNG model requires fewer devices at the network edge; however, this approach could result in potentially higher costs in the aggregation layer.

    4. The main benefit to the hybrid BNG model, where a mixture of centralized and distributed BNGs is employed, is flexibility. The hybrid model allows a central BNG to be efficiently employed in a low-subscriber density area or a new market. In areas with high density, a distributed BNG can be employed. Another value of a hybrid architecture, particularly when seamless MPLS is involved, is that the service edge can be placed in the location that is most appropriate to the service being terminated.
