MULTI-OBJECT INTEREST USING NETWORK NAMES
One embodiment provides a system that facilitates multi-object interest using network names. During operation, the system generates a first interest comprising a name of a content object of a remote node and a first window size. The name potentially represents a collection of objects at the remote node. The window size indicates a number of additional objects the system can accommodate. The node further obtains from a first response corresponding to the first interest a manifest of the collection of the remote node and from a second response corresponding to the first interest a first object listed in the manifest.
1 . A computer-executable method, comprising:
generating, by a computing device, a first interest comprising a name of a content object of a remote node and a first window size, wherein the name potentially represents a collection of objects at the remote node, and wherein the window size indicates a number of additional objects the computing device can accommodate;
obtaining from a first response corresponding to the first interest a manifest representing of the collection of the remote node; and
obtaining from a second response corresponding to the first interest a first object listed in the manifest.
2 . The method of claim 1 , wherein the manifest corresponds to an ordered list of names and hashes that identify the objects of the collection.
3 . The method of claim 1 , wherein a node forwarding the first interest reduces the first window size based on a network condition.
4 . The method of claim 1 , further comprising:
obtaining a second window size from the first response; and
creating Pending Interest Table (PIT) entries for objects in responses, wherein the second window size indicates the number of PIT entries to be made.
5 . The method of claim 4 , further comprising evaluating a network condition at the current node and reducing the second window size before forwarding the first response.
6 . The method of claim 5 , further comprising:
in response to reducing the second window size, marking a PIT entry for an object to be for a cache in the current node; and
in response to identifying the object in a response, storing the object in the cache in the current node.
7 . The method of claim 6 , further comprising:
identifying an interest for the object stored in the cache in the current node;
sending a second response corresponding to the interest; wherein the second response comprises the object from the cache in the current node.
8 . The method of claim 1 , further comprising generating a second interest comprising the name, a hash of the manifest, an offset in the manifest, and a third window size, wherein the offset indicates an order of an object listed in the manifest.
9 . The method of claim 8 , further comprising:
obtaining a second window size from the first response; and
generating the third window size based on a second window size.
10 . The method of claim 9 , wherein a difference between the first and the second window sizes indicates a network condition at a remote node.
11 . A computer-executable method, comprising:
identifying, by a computing device, in a first interest a name of a content object and a window size, wherein the name potentially represents a collection of objects at a local node, and wherein the window size indicates a number of additional objects transmittable in a pipeline;
creating a first response corresponding to the first interest, wherein the first response comprises a manifest of the collection of the local node; and
in response to identifying a non-zero window size, creating a second response corresponding to the first interest, wherein the second response comprises a first object listed in the manifest.
12 . 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:
generating a first interest comprising a name of a content object of a remote node and a first window size, wherein the name potentially represents a collection of objects at the remote node, and wherein the window size indicates a number of additional objects the computer can accommodate;
obtaining from a first response corresponding to the first interest a manifest of the collection of the remote node; and
obtaining from a second response corresponding to the first interest a first object listed in the manifest.
13 . The non-transitory computer-readable storage medium of claim 12 , wherein the manifest corresponds to an ordered list of names and hashes that identify the objects of the collection.
14 . The non-transitory computer-readable storage medium of claim 12 , wherein a node forwarding the first interest reduces the first window size based on a network condition.
15 . The non-transitory computer-readable storage medium of claim 12 , wherein the method further comprises:
obtaining a second window size from the first response; and
creating Pending Interest Table (PIT) entries for objects in responses, wherein the second window size indicates the number of PIT entries to be made.
16 . The non-transitory computer-readable storage medium of claim 15 , wherein the method further comprises evaluating a network condition at the current node and reducing the second window size before forwarding the first response.
17 . The non-transitory computer-readable storage medium of claim 16 , wherein the method further comprises:
in response to reducing the second window size, marking a PIT entry for an object to be for a cache in the current node; and
in response to identifying the object in a response, storing the object in the cache in the current node.
18 . The non-transitory computer-readable storage medium of claim 17 , wherein the method further comprises:
identifying an interest for the object stored in the cache in the current node;
sending a second response corresponding to the interest; wherein the second response comprises the object from the cache in the current node.
19 . The non-transitory computer-readable storage medium of claim 12 , wherein the method further comprises generating a second interest comprising the manifest name, a hash of the manifest, an offset in the manifest, and a third window size, wherein the offset indicates an order of an object listed in the manifest.
20 . The non-transitory computer-readable storage medium of claim 19 , wherein the method further comprises:
obtaining a second window size from the first response; and
generating the third window size based on a second window size.
21 . The non-transitory computer-readable storage medium of claim 20 , wherein a difference between the first and the second window sizes indicates a network condition at a remote node.
22 . 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:
identifying in a first interest a name of a content object and a window size, wherein the name potentially represents a collection of objects at a local node, and wherein the window size indicates a number of additional objects transmittable in a pipeline;
creating a first response corresponding to the first interest, wherein the first response comprises a manifest of the collection of the local node; and
in response to identifying a non-zero window size, creating a second response corresponding to the first interest, wherein the second response comprises a first object listed in the manifest.
