US 10,122,624 B2 · System and method for ephemeral entries in a forwarding information base in a content centric network

Abstract

One embodiment provides a system that facilitates efficient management of a forwarding information base (FIB). During operation, the system receives, by an intermediate node, a first interest which includes a name and a condition for removing a first entry from a FIB, wherein a name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level. In response to obtaining the first entry from the FIB based on the name for the first interest, the system adds to the first entry the condition included in the first interest as a lifetime value for the first entry. In response to determining that the lifetime value is satisfied, the system removes the first entry from the FIB, thereby facilitating the intermediate node to efficiently manage the FIB based on information provided by a content producing device.

Dependent claims

A computer system for facilitating ephemeral entries in a forwarding information base, the system comprising:

a processor;
and
a storage device storing instructions that when executed by the processor cause the processor to perform:
receiving, by an intermediate node, a first interest which includes a name and a condition for removing a first entry from a forwarding information base, wherein a name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level;
in response to obtaining the first entry from the forwarding information base based on the name for the first interest, adding to the first entry the condition included in the first interest as a lifetime value for the first entry;
and
in response to determining that the lifetime value is satisfied, removing the first entry from the forwarding information base,
thereby facilitating the intermediate node to efficiently manage the forwarding information base based on information provided by a content producing device.

5 more elements

A computer-implemented method for facilitating ephemeral entries in a forwarding information base, the method comprising:

receiving, by an intermediate node, a first interest which includes a name and a condition for removing a first entry from a forwarding information base, wherein a name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level;
in response to obtaining the first entry from the forwarding information base based on the name for the first interest, adding to the first entry the condition included in the first interest as a lifetime value for the first entry;
and
in response to determining that the lifetime value is satisfied, removing the first entry from the forwarding information base,
thereby facilitating the intermediate node to efficiently manage the forwarding information base based on information provided by a content producing device.

2 more elements

A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method, the method comprising:

receiving, by an intermediate node, a first interest which includes a name and a condition for removing a first entry from a forwarding information base, wherein a name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level;
in response to obtaining the first entry from the forwarding information base based on the name for the first interest, adding to the first entry the condition included in the first interest as a lifetime value for the first entry;
and
in response to determining that the lifetime value is satisfied, removing the first entry from the forwarding information base,
thereby facilitating the intermediate node to efficiently manage the forwarding information base based on information provided by a content producing device.
