Fig. 2 is the structural representation of embodiment of the present invention network resource management system.
Embodiment
The realization flow of embodiment of the present invention method for managing network resource as shown in Figure 1, comprises the following steps:
Step 101: when strategic server receives the strategy request that applied business server sends, the loading end information of information, user signing contract information and the current access of user of the institute's requested service carrying according to the strategy request receiving, generation strategy parameter is also issued to the policy enforcement function body of first hop router (first-hop router) of loading end;
Wherein, described policing parameter comprises: IP address and the receiving port number of IP five-tuple, QoS demand parameter and the user gateway (BNG) of institute's requested service, be contained in respectively in the loading end information of information, user signing contract information and the current access of user of institute's requested service; The information of institute's requested service, user signing contract information are all stored in applied business server, and the loading end information of the current access of described user offers the loading end information of user's access of applied business server while being the last logging in network of user.
Step 102: policy enforcement function body is mapped to the policing parameter receiving the RSVP object of RSVP (RSVP) the agreement end of first-hop router.
Wherein, described RSVP object comprises: session (session) field, transmitting terminal template (sendertemplate) field and transmitting terminal specification (sender_TSPEC) field;
Describedly policing parameter be mapped to RSVP object be specially:
The IP address of the BNG that described policing parameter is comprised and receiving port number are mapped to respectively receiving terminal address (receiver address) field, receiving terminal port (receiver port) field that described session field comprises, and protocol number in the IP five-tuple that described policing parameter is comprised is mapped to agreement ID (protocol ID) field that described session field comprises;

The QoS demand parameter that described policing parameter is comprised is mapped to described sender_TSPEC field.
Step 103: described RSVP end is sent to described RSVP object by RSVP path (RSVP path) message the RSVP client of loading end all the other each routers except first-hop router, and each RSVP client is institute's requested service bandwidth reserved according to RSVP object.
Wherein, described RSVP end is sent to loading end RSVP client of all the other each routers except first-hop router by RSVP path message by described RSVP object and is:
Described RSVP end generates and carries the RSVP path message of RSVP object and pass through the RSVP client of the each router of loading end to the RSVP client transmission of loading end BNG; Wherein, the final jump that BNG is loading end, for connecting loading end and user's side;
Described each RSVP client comprises for institute's requested service bandwidth reserved according to RSVP object:
Step a1, the RSVP Object Creation path state that the RSVP client RSVP path message that forwarding comes according to upper hop router of all the other each routers is carried except BNG, and forward the next RSVP path message of this upper hop router forwarding to next hop router, until RSVP path message is while arriving the RSVP client of BNG, execution step b1;
Wherein, described path state comprises the address of described RSVP object and upper hop router, and described RSVP object is used for, so that its next hop router sends signaling or data to it;
The RSVP Object Creation path state that the RSVP client of step b1, BNG is carried according to the RSVP path message receiving and calculating need to be the reserved bandwidth of institute's requested service, for the reserved bandwidth of calculating of institute's requested service, and the RSVP client of passing through all the other routers of loading end is to RSVP end loopback RSVP path message;
The RSVP calculation and object that the RSVP path message of step c1, the RSVP client loopback that forwarding comes according to next hop router of all the other each routers except BNG is carried need to be the reserved bandwidth of institute's requested service, for the reserved bandwidth of calculating of institute's requested service, and the RSVP path message of the loopback that this next hop router forwarding is come is forwarded to upper hop router; Until RSVP termination is received the RSVPpath message of loopback,, the RSVP path message of loopback arrives first-hop router, and RSVP end is replied and reserved message to strategic server by policy enforcement function body, finishes this resource reservation flow process.
After step 103, when completing or stopping business, the embodiment of the present invention also comprises: discharge reserved resource.
Wherein, while stopping business when finishing service or by applied business server, the reserved resource of described release comprises:
When step a2, strategic server receive the resource release request that applied business server sends, strategic server sends and discharges bandwidth notice to described policy enforcement function body;
The release bandwidth receiving is notified IP five-tuple that institute's requested service of carrying is corresponding and IP address and the receiving port number of BNG by step b2, policy enforcement function body, and the RSVP path that is mapped to described RSVP end deletes (RSVP path tear) object; RSVP end generates and carries the RSVP path tear message of RSVP path tear object the RSVP client transmission to loading end BNG;
Step c2, the RSVP path tear message that the RSVP client of all the other each routers is sent to upper hop router except BNG, delete path state corresponding to RSVP path tear object that this RSVP path tear message is carried, and discharge resource corresponding to RSVP path tear object that this RSVP path tear message is carried, and down hop router forwards this RSVP path tear message, until RSVP path tear message arrives when BNG, execution step d2;
The RSVP client of steps d 2, BNG is deleted path state corresponding to RSVP path tear object that the RSVP path tear message that receives is carried, and discharges resource corresponding to RSVP path tear object that the RSVP path tear message that receives is carried; And reply Release complete to strategic server by RSVP client, RSVP end and the described policy enforcement function body of all the other each routers of loading end, finish this resource release flow.
While stopping business by loading end, the reserved resource of described release comprises:
The RSVP client of step a3, BNG is deleted path state corresponding to institute's requested service, and discharge after the resource that institute's requested service takies, generate RSVP path tear message the RSVP client by loading end each router except BNG to the transmission of RSVP end;
Step b3, the RSVP path tear message that the RSVP client of all the other each routers is sent to next hop router except BNG, delete path state corresponding to RSVP path tear object that this RSVP path tear message is carried, and discharge resource corresponding to this RSVP path tear object, and upper hop router forwards this RSVP path tear message, until RSVP path tear message is while arriving RSVP end, until RSVP path tear message while arriving first-hop router, execution step c3;
Step c3, RSVP end are replied Release complete to strategic server by described policy enforcement function body, finish this resource release flow.
