The core network of AccessTEL consists of 4 distinctive parts; routing, switching, traffic shaping & core IP services application management. AccessTEL network core is designed for high speed, reliability and scalable advanced IP network. The network core is currently MPLS backbone. It currently supports IPv4, IPv6, scalable multicast and other networking protocols. The IP/MPLS core is the backbone that interconnects all Ethernet aggregation networks and the Service/Application layer.
The core is connected to redundant aggregation level TSR metro ethernet switches. These are in turn connected to a resilient fiber ring that supports carrier-class automatic failure protection. MPLS-based Traffic Engineering, VPN capabilities and QOS allow this network to provide a whole suite of networking solutions to customers.
The Service layer hosts the core applications, essential to functioning and management of the network. This is where AAA policies are enforced and billing data is collected. The Application layer hosts applications that are value additions, for example, Mail, IP Telephony etc.
