Abstract:
Disclosed herein are a method and apparatus for processing MMTP packets. When an MMTP packet is transmitted, the packet processing apparatus calculates a reference value from partial field values of a reference MMTP packet header, and inserts the calculated reference value into the compressed header. By the reference value, MMTP packets may be correctly distinguished and may be correctly referred to when there are two reference MMTP packets in which the lower 5 bits of packet sequence numbers are identical to each other, or even when the number of reference MMTP packets is a multiple of 256.
Abstract:
Disclosed herein are an in-network caching apparatus and method. The in-network caching method using the in-network caching apparatus includes receiving content from a second node in response to a request from a first node; checking a Conditional Leave Copy Everywhere (CLCE) replication condition depending on a number of requests for the content; checking a priority condition based on a result value of a priority function for the content; checking a partition depending on the number of requests for the content; performing a cache replacement operation for the content depending on a result of checking the partition for the content; and transmitting the content to the first node.
Abstract:
A method of collecting peer-to-peer (P2P)-based content sending/reception information is disclosed herein. In the method of collecting P2P-based content sending/reception information, a first peer accesses a second peer, and exchanges buffer maps with the second peer. The first peer requests the second peer to send a piece of content not owned by the first peer. When the reception of the piece of the content is completed, the first peer generates a receipt message and then signs the receipt message. The first peer sends the signed receipt message to the second peer. The second peer signs the signed receipt message again. The second peer sends the dually signed receipt message to a server.
