Embodiment Construction

[0040] Each DNS query will occupy a session of the firewall, and if the DNS query is mostly carried on UDP, the session cannot be actively released after the query is completed, and a large number of firewall sessions will be wasted.

[0041] In order to solve the above problems, embodiments of the present invention provide a session management method and device. The DNS aggregation function is implemented in the user plane functional entity (SAE-GW, System Architecture Evolution Gateway). Using a mapping method, multiple DNS UDP sessions initiated by a user are aggregated into one TCP session and sent to the DNS server to reduce PDN. side session count purposes.

[0042] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

Abstract

The invention provides a session management method and device, relates to the field of Internet, and aims to solve the problem of short firewall session number resources. The method comprises the following steps: establishing a unique transmission control protocol (TCP) session for each DNS (Domain Name System) client; receiving a DNS inquiry request carried in a user datagram protocol (UDP) session; and confirming a TCP session of the DNS client corresponding to the UDP session, and forwarding the DNS inquiry request to a DNS server through the TCP session. The technical scheme provided by the invention is suitable for a DNS inquiry process, and a plurality of UDP sessions are converged into one TCP session on a firewall.

Description

technical field [0001] The invention relates to the Internet field, in particular to a session management method and device. Background technique [0002] With the explosive development of the Internet, especially with more and more internal and external links and pictures on the webpage, there are more and more Domain Name System (DNS, Domain Name System) messages on the network, and each DNS query will occupy a session of the firewall. And if the DNS query is mostly carried on the User Datagram Protocol (UDP, User Datagram Protocol), the session cannot be actively released after the query ends, and a large number of firewall sessions will be wasted. According to current calculations, DNS has already accounted for 20% of the number of sessions in the entire network, and the number of sessions on the firewall is increasingly tight. Contents of the invention [0003] The invention provides a session management method and device, which solves the problem of shortage of fire...
