摘要： Disclosed are a method for setting a plurality of sessions and a method for transmitting/receiving data using the same. According to an exemplary embodiment of the present invention, at least some of the data including attribute information of the data are received through initial sessions, the number of additional sessions for receiving the data is calculated by using the attribute information of the data, and the additional sessions are set as many as the calculated number of additional sessions. According to the exemplary embodiments of the present invention, various and complicated states of the communication network can be reflected to session setting as the configuration of the communication network becomes more and more complicated and the sessions depending on the state of the communication network can be set, thereby transmitting data more effectively.

摘要： Round-trip time (RTT) for communication between an edge point of presence (POP) in a content delivery network (CDN) and a local domain name server (LDNS) is determined by resolution of a canonical name (CNAME) record. A first server in a first edge POP in a CDN receives a request to resolve a domain name from a LDNS and transmits a CNAME record including a timestamp indicating when the CNAME record was transmitted to the LDNS. The first server subsequently receives a request from the LDNS to resolve the CNAME record and determines a RTT time indicating the time needed for round-trip transmission between the LDNS and the first server based on the time when the request to resolve the CNAME request was received by the first server and the time indicated by the timestamp.
摘要翻译：通过标准名称（CNAME）记录的分辨率来确定用于内容传送网络（CDN）中的边缘存在点（POP）与本地域名服务器（LDNS）之间的通信的往返时间（RTT）。 CDN中的第一边缘POP中的第一服务器从LDNS接收到解析域名的请求，并且发送包括指示CNAME记录何时发送到LDNS的时间戳的CNAME记录。第一服务器随后从LDNS接收到解析CNAME记录的请求，并根据接收到解决CNAME请求的请求的时间确定指示LDNS和第一服务器之间往返传输所需的时间的RTT时间由第一个服务器和时间戳指示的时间。

摘要： Data access time in content delivery networks is improved by storing files in cache servers as file bundles. A cache server determines that multiple files are requested by the same client based on information available in the request including the IP address of the client, a URL of a webpage referring to the file, and/or a cookie stored at a client. The cache server stores multiple files requested by the same client on the hard drive as a file bundle with meta data associating the files with one another, such that they can be accessed together. A future request from the client for a file in a file bundle results in multiple files from the file bundle being loaded in the memory. If the client requests another file from the file bundle, the file is accessed directly from the memory instead of the hard drive, resulting in improved performance.
摘要翻译：通过将文件作为文件包存储在缓存服务器中，可以提高内容传送网络中的数据访问时间。缓存服务器根据请求中可用的信息（包括客户端的IP地址，引用该文件的网页的URL）和/或存储在客户端的cookie来确定同一客户端请求多个文件。高速缓存服务器将由同一客户端请求的多个文件存储在硬盘驱动器上作为文件包，其中元数据将文件相互关联，以便它们可以一起访问。来自客户端对文件包中的文件的未来请求会导致文件包中的多个文件被加载到内存中。如果客户端从文件包请求另一个文件，则直接从内存访问该文件，而不是硬盘驱动器，从而提高性能。

摘要： Disclosed are a method and an apparatus for calculating a distance in a contents delivery network. According to one preferred embodiment of the present invention, when a domain name resolution request is received from an LDNS, an identifier is added to a domain name requested to be resolved so as to create a CNAMEd domain name response, the CNAMEd domain name response is transmitted to a probe server, the CNAMEd domain name response transmitted to the probe server is transmitted to the LDNS after a source IP address thereof has changed into an address of a name server in the probe server, the name server receives a resolution request to the CNAMEd domain name response from the LDNS, and the name server determines, as a distance between the LDNS and a point of presence (POP), a value obtained by subtracting a distance between the name server and the LDNS and a distance between the name server and the probe server from an interval between a time for transmitting the CNAMEd domain name response from the name server to the probe server and a time for receiving, by the name server, the resolution request to the CNAMEd domain name response from the LDNS. According to the present invention, even when the probe server cannot calculate a distance to the LDNS, a distance between the LDNS and the POP can be calculated, and thus it is possible to improve and stabilize the quality of a contents delivery network service.
