Ethernet QoS: Trust, But Always Verify

Unlike legacy Frame Relay and later ATM, Ethernet initially lacked the quality of service (QoS) guarantees that business customers had grown accustomed to. Not surprisingly, enterprises and even wholesale carrier customers were reluctant to adopt Ethernet services. By creating mechanisms that separate different QoS service levels via virtual LANs: “best-effort”, priority data, and a stringent QoS class, service providers can offer various service level agreements (SLAs) to meet enterprise or wholesale carrier customer requirements. Of course, service providers have to provide consistent Ethernet QoS whether the service is running over their own network or a third-party provider partner. While service providers have more direct control of Ethernet QoS when it runs on their own network, it becomes even more challenging when they have to leverage a third-parties’ facilities to meet a customer’s needs that reside outside their network footprint.
