New coding scheme to minimize the total local delay in the switching elements. Under the new coding scheme, the switching element can be optimized such that it can start to produce the first output bits of the output packets without having to wait for the complete arrival of all of the local routing bits, and hence reduces the local buffering delay. In practical switching applications, each switching element in a multistage switching network supporting multicasting is a bicast cell, and the concomitant new coding scheme can even achieve a minimum delay in each bicast cell. Hence the total latency of the overall switching network is minimized.

Optimizing switching element for minimal latency

A broadband packet switch that handles all packets that arrive within the same frame time by simultaneously bit-pipelining the packets into different sections of the one-stop packet buffer through an input switch. Each packet remains in is selected section until its eventual exit from the buffer through an output switch. Access to the memory storage in which the packet buffer resides is not through a memory bus or buses, thereby engendering massive parallel access.

Modifications to the 2-stage interconnection to allow flexible scalability. Different switching fabrics having a range of different sizes can be constructed out of the same set of I/O switching nodes through this modified 2-statge interconnection, which can further be recursively invoked to construct large switching fabrics with desirable sizes. The recursive construction incorporating the modified 2-stage interconnection can seamlessly be realized through the five hierarchical levels of physical implementation, including inside-chip implementation, PCB implementation, orthogonal packaging, interface-board packaging and fiber-array packaging. The routability of the resulting switching fabric is always guaranteed and self-routing mechanism is also pertained.

Scalable 2-stage interconnections

New routing techniques over a packet switching network so that the protocol processing at inter-node line cards is drastically simplified or even eliminated altogether. These techniques utilize an ingress node of the packet switching network for translating the routing information into a fixed route encoded as a sequence of in-band control signals, fragmenting the packet into cells of a fixed length, and affixing the sequence of in-band control signals in front of each of the cells, deploying the in-band control signals in a sequence in nodes on the route to guide each of the cells through the sequence of nodes and then consuming the in-band control signals, and at an egress node reassembling the cells into the packet.
