A service flow in wimax is partially characterized by the following attributes:
★ A 32-bit Service Flow ID (SFID) is assigned to all existing service flows. The SFID serves as the principal identifier for the Service Flow and has an associated direction.
★ A 16-bit Connection ID (CID) is associated with each active SFID (connection active).
★ A set of QoS parameters specifying the REQUIRED resources. The principal RESOURCE is bandwidth, but the SPECIFICATION may also include LATENCY requirements.
★ A set of QoS parameters defining the level of service being provided.
