Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. First, let’s further elaborate on the problems of cross-domain SLA signing:

[0053] see figure 1 , large enterprise users need to establish a virtual private network VPN between two branches (Private Network1 and Private Network2) in different locations, and VoIP service providers need to reserve bandwidth between two VoIP Gateways. The actual network status is: AS1 and AS3 belong to network provider NP1, AS2 and AS5 belong to network provider NP2, and AS4 belongs to network provider NP3. From figure 1 As can be seen in the figure, there are many options for large enterprise users to build VPN: (1) AS1->AS2->AS4; (2) AS1->AS3->AS4; (3) AS1->AS5->AS4, etc. In the first and third schemes, large enterprise users need to sign SLAs with NP1, NP2, and NP3 respectivel...

Abstract

A dissociation device of a service level specification (SLS) in a multidomain heterogeneous IP network is composed of a user interface module, a router analysis module, per-domain behavior PDB information acquiring module and a parameter dissociation module connected orderly. The said device uses distributed technology and is set in each autonomous domain or several domains share one said device, web service or public objects are applied to request an agent unit CORBA interface to exchange information. The device can provide reference information of related single domain to customers signing SLA crossing multidomain with the network providers, so that, the customer can know the SLS of each autonomous domain on the entire path when signing SLA of multidomain and heterogeneous IP network.

Description

technical field [0001] The present invention relates to a device and method for providing quality of service assurance services in an IP network, specifically, to a device and method for decomposing service level specifications in a multi-domain heterogeneous IP network, and belongs to the technical field of network interconnection communication. Background technique [0002] With the development of the Internet, people increasingly realize that providing value-added services on the Internet can obtain high profits. As a result, various value-added services have appeared on the Internet: (1) content providers (such as Sina, Sohu) attract users to browse their web pages by providing users with categorized information, and advertise businesses on the web pages, so as to provide users with merchants charge fees; (2) VoIP: IP telephony, as a low-cost calling method, has attracted many users, so it has become a powerful driving force for the development of the Internet; (3) VPN: ...
