Abstract
The present disclosure provides a fabric ingress scheduler and method that distributes ingress packet traffic in a time division multiplex (TDM) system, both fabric interface aggregate and per connection, deterministically across fabric paths. Advantageously, the fabric ingress scheduler and method minimizes fabric latency and prevents fabric interface head-of-line blocking. The fabric ingress scheduler and method utilizes the fact that each connection flow has a known maximum rate which must be reserved through the fabric for prevention of data loss (essentially circuit switching using a packet fabric). In exemplary embodiments, the fabric interface supports per packet fabric path selection. Generally, the fabric ingress scheduler and method generally provides a deterministic scheduling of ingress packets to fabric paths.
