Last-Mile Prioritization, Packet Loss and Availability

Appliance-based SD-WANs only prioritize upstream traffic. They typically include Active/Active Protection for aggregating capacity and blackouts protection. Policy-based Routing (PbR) selects the optimum path for UC sessions. Packet mitigation techniques may be available.

Cato Cloud QoS prioritizes upstream and downstream last-mile access. Active/Active Protection and PbR aggregate capacity, protect against not only blackouts but also brownouts and select the optimum path. Packet Duplication and Fast Packet Recovery mitigate last-mile packet loss.

Middle-Mile Optimization

SD-WAN appliances rely on the unpredictable Internet. They cannot compensate for the latency from poor Internet routing or the packet loss caused by congested peering points.

Cato avoids Internet problems by using the Cato Cloud network, a private, global, network of PoPs built on top of multiple SLA-backed tier-1 carriers. Optimized routing algorithms direct UC traffic across the paths with the least latency and packet loss.

UCaaS Access

SD-WAN appliances do not provide UCaaS access out-of-the-box. Organizations must first identify the location of their UCaaS provider and somehow deploy an appliance near the provider’s premises.

Cato natively supports UCaaS and cloud datacenters (IaaS) without additional configuration, complexity, or point solutions. Cato intelligently drops UCaaS traffic at the Cato Point of Presence (PoP) closest to the UCaaS instance across the globe to minimize latency and packet loss.

Security

SD-WAN appliances require additional security appliance and services to protect against network attacks and Internet threats.

Cato’s converged security stack protects UC components against network attacks and Internet-borne threats without the need for dedicated appliances or additional security services.
