A method for balancing load on a network by selecting a path based on a load balancing algorithm and assigning one of several pairs of endpoint addresses for a flow based on the path selected. One pair of endpoint addresses corresponds to a first path and another pair of endpoint addresses corresponds to a second path. If the first path is selected, the first pair of endpoint addresses is assigned to the flow. If the second path is selected, the second pair of endpoint addresses is assigned to the flow. In one embodiment, based on the assigned pair of endpoint address, the flow is switched to an endpoint by the selected path.

Multipathing using multiple endpoint addresses for load balancing in a network

A receiving node sends a token identifier to the data source and receives data from the data source, along with the token identifier. A token identifier identifies a location in memory on the receiving node, but is not the same as an address in the memory. In the described embodiments, a token identifier is an integer value that acts as an index into a token array, which identifies the memory location.

Protocol to implement token ID mechanism for network data transfer

Validation of various portions of received data, including validating a cut-through checksum found in a received data packet. The cut-through checksum is based on data found in a packet header, and thus can be validated before the entire packet is received. This feature allows processing of the received data to begin before the entire packet has been received. Many embodiments will also receive a checksum that is based on the entire packet.

Cut-through decode and reliability

A node in a network that receives data from a data source, such as another node. The receiving node sends a token identifier to the data source and receives data from the data source, along with the token identifier. A token identifier identifies a location in memory on the receiving node, but is not the same as an address in the memory. Thus, a token identifier is preferably neither a physical memory address nor a virtual address.
