Abstract: Content distribution system cache management may be provided. First, a sync packet may be received by a cache server from a first server. The sync packet may include a list indicating a cache server where a chunk is to be stored and the address for the chunk. Next, an address for the chunk may be obtained by the cache server by parsing the sync packet. The cache server may then determine that the chunk is not stored on the cache server by using the address for the chunk. Next, in response to determining that the chunk is not stored on the cache server, a connection may be opened between the first server and the cache server. The cache server may then receive the chunk over the connection and cache the chunk on the cache server.

- 06 Mar 2015
TL;DR: In this article, a method for obtaining a packet at a network endpoint from a client via a first segment has been proposed, where the packet has a segment routing header that includes a list of addresses attached to a chunk entry, and is configured to identify at least a first chunk requested by the client.

TL;DR: In this paper, the steering order of SL Groups is not required to be the same order as they are listed in the Segment List, as the value of Segments Left may be increased, remain the same, or decreased (possibly to skip a next SL Group) and possibly based on the result of an evaluation of a conditional expression.

- 21 Dec 2009
TL;DR: In this paper, the authors propose a method and apparatus for protecting an application layer in a computer network system, which includes creating a session between a client and a data provider in response to a session connection request from the client, and determining the client as an attack client when the client generates a session termination request before the data provider transmits to the client a response packet to a data request.
