Abstract

One embodiment provides a system that facilitates cut-through forwarding of message fragments over a network. During operation, the system receives a packet that corresponds to a fragment of a message and contains a fragment header. The system stores in a data structure a mapping relationship between the fragment header and a hierarchically structured variable-length identifier (HSVLI), wherein the HSVLI comprises contiguous name components ordered from a most general level to a most specific level. The system makes a forwarding decision for the packet based on the fragment header prior to receiving all fragment packets associated with the message, thereby facilitating cut-through forwarding of the message fragments over a network.

First claim

What is claimed is:

1. A computer-implemented method for forwarding packets, the method comprising:
determining, by a content-requesting node, a maximum transmission unit of a network;
fragmenting, by the content-requesting node, a message into one or more packets, wherein the size of each packet is less than or equal to the maximum transmission unit of the network;
generating, by the content-requesting node, a flow identifier which indicates that a respective packet correspon…
