Embodiment Construction

[0026] In the embodiment of the present invention, in order to realize the separation of uplink data and downlink data of the cluster system at the transport layer, the load balancer first needs to obtain relevant information about communication between it and the client and server through the transport layer protocol. The information includes IP address and port information, and the load balancer sends the relevant information to the server. The server saves the relevant information.

[0027] After the load balancer receives the data packet sent by the client through the transport layer protocol, according to the request content of the data packet, the load condition of the server and the distribution of the request content in the server cluster, obtain the corresponding Server IP address and port information. The load balancer modifies the source IP address of the data packet to the IP address of the load balancer, modifies the source port of the data packet to the port use...

Abstract

The invention provides a method and a device which are used for realizing the separation of the data in an upper row from the data in a lower row. The method mainly comprises that a load balancer obtains the relative information for communication between the load balancer and a client and between the load balancer and a server by a transmission layer protocol; wherein the relative information includes IP addresses and port information and the load balancer transmits the relative information to the server; the load balancer receives the data packets transmitted by the client through the transmission layer protocol and then transfers the data packets to the server according to the relative information, and the server directly transmits the data packets to the client according to the relative information. The invention can realize the separation of the data in the upper row from the data in the lower row in cluster systems such as IPTV using the load balancer, reduce the pressure of the load balancer and greatly improve the toughness of the systems.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for realizing the separation of uplink and downlink data. Background technique [0002] With the rapid development of economy and technology, the Internet (Internet) has brought great changes to people's work, life and entertainment with its rich resources, personalized service and convenient interaction. With the continuous progress of the times, people hope to watch their favorite TV programs anytime and anywhere, and hope to realize the real interaction between media providers and media consumers. Therefore, the timing of traditional TV technology and the service function of one-way broadcasting can no longer meet the above-mentioned needs of people. In this case, IPTV (Interactive Internet Television) technology came into being. [0003] IPTV is a new Internet-based technology and a brand-new media form of personalized and interactive services. It i...
