Aggregation and provider edge are critical network applications for the reliable delivery of connectivity services to end users. But it’s not so simple.
The network must be capable of scaling to meet increasing bandwidth needs while still offering rich features and protocols.
The central points in the network aggregate the traffic coming from the edges (access and mobile backhauling). As each Network Element (NE) aggregates thousands of users, redundancy at the NE level is also critical.
With its advanced control plane architecture, ExaNOS provides redundancy for every layer of the network:
- At the NOS level, each process is isolated and protected from other faulty processes. Graceful Restart enables continuous forwarding functions without relying on human intervention.
- At the logical level, redundancy is natively offered by routing protocols (BFD, VRRP, ISSU).
- At the hardware level, redundant fans and power supply provide additional backup.
The provider edge (PE) router is located at the edge of the service provider’s network and connects the interface between the customer-facing network (access or DCSG) and the core. As customers move to SaaS services, they expect an uncompromising quality. Service Providers must support the growing traffic and low latency applications at the Provider Edge.
ExaNOS addresses your PE needs with a variety of features and protocols. We support all the routing protocols from layer 2 to the most recent BGP protocol extensions, VPN services (L2VPN and L3VPN), advanced QoS and traffic prioritization.
