TLDR
In this paper, a method of high speed assemble process capable of dealing with long packets with effective buffer memories usage is presented, which includes, receiving fragmented packets, identifying whether the received packet is a packet fragmented into two from original, or a packet fragmentation into three or more, storing the two fragmented packets into assembly buffer in fragmentation order, on basis of the respective offset values in the packets, and reading out from top.Abstract:
The present invention provides a method of high speed assemble process capable of dealing with long packets with effective buffer memories usage. A processing method of fragmented packets in packet transfer equipment for transmitting and receiving packet data between terminals through network, includes, receiving fragmented packets, identifying whether the received packet is a packet fragmented into two from original, or a packet fragmented into three or more, for the packet identified as fragmented into two, storing the two fragmented packets into assembly buffer in fragmentation order, on basis of the respective offset values in the packets, and reading out from top, and for the packet fragmented into three or more, chain-connecting the assembly buffers and storing the packets therein in reception order, reading out the packets after deciding the order by comparing chain information and offset values of the fragmented packets within the chain, and then reassembling the packets.read more

Controlling the spread of interests and content in a content centric network
TL;DR: In this paper, the authors present a system for controlling the spread of interests and content in a content centric network (CCN), which maintains a routing policy for content data and receives a packet associated with a piece of content or an interest for the content.
Patent
Adaptive multi-interface use for content networking
TL;DR: In this article, a hierarchical structured variable-length identifier (HSVLI) is used to indicate a piece of content and indicate a hierarchical structure of contiguous components ordered from a most general level to a most specific level.
Patent
Ordered-element naming for name-based packet forwarding
TL;DR: In this paper, a name-based content-forwarding system generates an ordered-element name for a content item, and can process an interest to identify and perform an action that satisfies the interest.

Reputation-based strategy for forwarding and responding to interests over a content centric network
Priya Mahadevan,Glenn C. Scott +1 more
TL;DR: In this paper, a CCN network node uses reputation values for one or more interfaces to determine how to forward an Interest or Content Object via a network interface, and selects a candidate outbound face with a reputation value exceeding a first predetermined threshold.
