This approach makes the network scalable, much more cost-effective, and future-proof.Ī good example is a technology called segment routing, which uses specific instructions to forward ‘packets’ of data between nodes over the shortest available route. The evolution of IP and Ethernet aggregation solutions will be based in openness, disaggregation, and orchestration, allowing network complexity to be abstracted to a Software-Defined Networking (SDN) layer and keeping the subsets of IP protocols into the platforms leaner. The future of IP and Ethernet aggregation The Top Six Features of a Truly Future-proof Converged Ethernet and IP Network This supports seamless, end-to-end provisioning for services being delivered over the network, reducing costly manual interventions and speeding up time to market for new services. IP aggregation networks typically support ‘dynamic’ traffic routing. Ethernet networks are also compact, efficient, and need fewer skilled resources to run and maintain.ĭespite these key benefits, Carrier Ethernet relies on Layer 2 techniques (Ethernet) to forward traffic over fiber, copper, and wireless networks requiring multiple provisioning steps to deliver an end-to-end service from the access layer into the IP core. Its benefits include simplicity and cost profile (born from its LAN heritage). The pros and cons of traditional Ethernet aggregationĮthernet usually supports a ‘static’ traffic routing approach. However, Ethernet services (Layer 2 services) must be able to deliver traffic from both common business Ethernet services (such as E-LINE, E-LAN, E-TREE, and E-ACCESS), as well as from common IP (Layer 3) services, including IP-VPN services, Ethernet VPN (EVPN) and, increasingly, SD-WAN services. When fully integrated with scalable optical network infrastructure, Ethernet connectivity services can help keep pace with bandwidth demands cost-effectively. Not only that, but managing the shift from 1GbE services to 10GbE, 25GbE or 100GbE services and aggregation to 100/200/400/GbE, requires major capacity increases. Preparing for the high-bandwidth future with Ciena Ethernet solutionsįor today’s networks, success depends on being able to deliver huge traffic volumes from end-users to offices, branches, the internet, and data centers cost-effectively.
