As the gap between stagnating service revenues and the demand for higher bandwidth grows, providers are looking for ways to better control their expenses while offering higher bandwidth and more services to more customers.
Typically today, an access network will be built from three distinct layers – the demarcation layer which will separate the domains of the different operators or service providers from the end users, the aggregation layer which will aggregate direct links or access rings, and the edge of the core which is typically aggregating the aggregation switches into the core routers.
Up until lately, a typical network would have 1GE connections to the business, cell site or the residential DSLAMs which were then aggregated to 10GE rings, but there is a growing amount of applications that drive 10GE solutions deeper into the network, such as:
- Growing amount of LTE and LTE Advanced deployments require 400Mbps to 1Gbps per site, which demand more than 1GE when deployed in ring topologies
- Small cell deployments, which in many cases consist of macro and small cells that require more than 1GE per cell site
- Macro cells aggregating local and remote microwave connected base stations
- Backhaul services for multiple mobile operators in one cell site
High bandwidth applications that require high capacity, like data center connectivity, low latency financial transactions, ‘big data’ backup and content delivery networks (CDN), all of which require more than 1GE connectivity
OAM aggregation – growing amount of OAM services throughout the network, with real time reporting to the client, require products that support more services and are able to initiate and terminate a large amount of OAM tests.
SDH/SONET replacement – evolution of enterprise PDH/SONET legacy services to packet-based services, combined with the growing need of bandwidth for cloud connectivity and data applications, drive higher bandwidths
Cloud-based services (SaaS, IaaS) drive the need for higher bandwidth in the access
While many of these applications do not require 10GE all the way to the end, they, in many cases, require more than 1GE and thus higher bandwidth 10GE aggregation. Resulting in a network that looks like this:
The T-Metro 8001 next generation 10GE service aggregation solution presents a breakthrough in Carrier
Ethernet and MPLS service delivery for service providers and mobile operators. The product boasts a 200GE capacity, offering double the capacity in one third the size of its closest competitor, making it the most compact, dense and cost effective 10GE service aggregation switch in the Carrier Ethernet market today.
