WiMAX Interview Question:

What is the Difference between CID and SFID in WiMAX system?

Submitted by: Administrator

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.
