Description
Technical field
The present invention relates to the media player of LINUX operating system, in particular, a kind of based on IPv4 agreement and media player and its implementation the IPv6 agreement, double-stack technology, LINUX operating system.
Background technology
Player is a kind of media vehicles commonly used, present player can play just based on local storage or based on the media file of IPv4 network streaming media server.The host-host protocol of Streaming Media comprises: RTP (RTP, Real-time Transport Protocol), RTCP Real-time Transport Control Protocol (RTCP, Real-time Transport Control Protocol), real-time streaming protocol (RTSP, Real Time Streaming Protocol), media description agreement (SDP, Session DescriptionProtocol) etc.
IPv4 is that (Internet Protocol, IP) the 4th edition also are that first is widely used to Internet protocol, constitute the agreement of the foundation stone of Internet technology now.Internet is exponential develop rapidly in recent years, causes the IPv4 address space to be close to exhaustion.The IP address becomes more and more rare, forces many enterprises to have to use NAT that a plurality of home addresses are mapped to a public ip address.Though the address transition technology has been alleviated the pressure of public ip address scarcity to a certain extent, it does not support some IP Security agreement and occurs all mistakes unavoidably that in map addresses this has caused some new problems again.And, also can not fundamentally solve the deficient problem in IP address by NAT, along with the rapid increase of networking gear, the IPv4 public address can exhaust one day fully.
Therefore, Internet engineering duty group (IETF) has been developed IPv6.This version combines a plurality of motions that IPv4 is upgraded.In design, IPv6 tries hard to avoid increasing too many new features, thereby reduces the impact to existing high level and lower layer protocol as much as possible.Redefine address space by IPv6.IPv4 adopts 32 bit address length, has only about 4,300,000,000 addresses, estimate will be assigned with in the period of 2005～2010 to finish, and IPv6 adopts 128 bit address length, almost can provide the address without restriction.Press the actual assignable address of conservative approach estimation IPv6, can distribute more than 1000 address on every square metre of area of the whole earth.In the design process of IPv6, except once and for all solves the address shortage problem, also considered in IPv4, to solve bad other problem.The main advantage of IPv6 is embodied in following several respects: enlarge address space, improve network entire throughput, improve service quality (QoS), fail safe better assurance arranged, support plug and play and mobility, better realize the multicast function.
IPv6 has enlarged address space widely, has recovered the end-to-end linkage function that originally loses because of the address is limited, for the universal of the Internet and in-depth development provide primary condition.Therefore, along with popularizing of IPv6 network, the IPv6 streaming media service of the Internet will more and more widely be used, and present player can only be play the Streaming Media based on the IPv4 wide area network, has brought inconvenience to the user.Simultaneously, because the universal of IPv6 needs long period of time, IPv4 and IPv6 network will for a long time and be deposited around here, and the wide area network media server of IPv4 and IPv6 also will for a long time and be deposited.
Double-stack technology is a kind of otherwise effective technique of IPv4 to the IPv6 transition.Node in the network is supported IPv4 and IPv6 protocol stack simultaneously, and source node is selected different protocol stacks for use according to the difference of destination node, and the network equipment selects different protocol stacks to handle and transmit according to the protocol type of message.
The dual stack node schematic diagram as shown in Figure 1, two stacks can realize on a single equipment, also can be two stack backbone networks.For two stack backbone networks, all devices wherein must be supported the IPv4/IPv6 protocol stack simultaneously, and the interface that connects dual-stack network must while configuration of IP v4 address and IPv6 address.Dual stack node has three kinds of mode of operations: only move the IPv6 agreement, show as the IPv6 node; Only move the IPv4 agreement, show as the IPv4 node; Two mode stacks are opened IPv6 and IPv4 agreement simultaneously.
Therefore, need the media player of supporting IPv4, IPv6 protocol double-stack technology simultaneously.
Summary of the invention
