The loading condition information that stream asset management device 301 reports according to each stream service equipment, whether the service state of judgement stream service equipment is normal.
Concrete, if the loading condition information that the stream service equipment sends comprises load capacity, the stream asset management device can not need to check stream service equipment state, the stream asset management device determines that above-mentioned stream service equipment service state is normal; If the loading condition information that the stream service equipment sends comprises the sign that service state is abnormal, stream asset management device 301 determines that above-mentioned stream service equipment service state is abnormal.For example, if stream service equipment 303a present load amount is 50M, mean that so stream service equipment 303a service state is normal; The current service state of stream service equipment 303b is out_of_service, means stream service equipment 303b current service abnormal state.
In addition, if the loading condition information that the stream service equipment sends comprises load capacity, the stream asset management device also upgrades the load capacity of this stream service equipment according to this load capacity.
For example, stream service equipment 303a is at report cycle T
nthe loading condition information reported comprises load capacity (300M), flow the load capacity that asset management device 301 will flow service equipment 303a and be updated to 300M, and the service state of judgement stream service equipment 303a is normal.Stream service equipment 303a is at report cycle T
n+1the loading condition information reported comprises out_of_service, and the service state that flows asset management device 301 this stream service equipment of judgement 303a is abnormal, and the service state of this stream service equipment 303a is updated to abnormality.
In the stream asset management device, the homogeneous turbulence service equipment is not distinguished with address information.The associated preservation of address information, load capacity and service status information of stream service equipment.
Optionally, can also safeguard the ultimate load of stream service equipment.So, above-mentioned stream asset management device 301 receives the ultimate load of this stream service equipment that the stream service equipments send; Judge whether to preserve the ultimate load of this stream service equipment; If so, upgrade the ultimate load of this stream service equipment of preserving; If not, preserve the ultimate load of this stream service equipment.For example, stream service equipment 303a, the 303b that stream asset management device 301 is preserved and the ultimate load of 303c are respectively 500M, 400M and 350M.
The process of carrying out the resource distribution according to the request of session management equipment specifically describes as follows:
When session management equipment is arranged to stream asset management device application stream resource points broadcast message, the stream asset management device flows service equipment according to the present load amount of all stream service equipments normally with service condition selecting present load amount minimum and service state.The present load amount can be the load capacity reported stream service equipment the last time.The current service state of stream service equipment 303a is abnormal, and the current service state of stream service equipment 303b and 303c is normal.The load capacity that stream service equipment 303b the last time reports is 300M, and the load capacity that stream service equipment 303c the last time reports is 240M.So, the current load capacity of stream service equipment 303c is 240M, is less than the present load amount of stream service equipment 303b, therefore selects stream service equipment 303c.
Selecting after load capacity minimum and service state flow service equipment normally, judging that above-mentioned present load amount minimum and service state flow the ultimate load whether bandwidth on demand sum in the present load amount of service equipment and above-mentioned stream resource points broadcast message is greater than above-mentioned stream service equipment normally.
If above-mentioned present load amount minimum and service state flow the ultimate load that bandwidth on demand sum in the present load amount of service equipment and above-mentioned stream resource points broadcast message is greater than above-mentioned stream service equipment, the stream resource points broadcast message that above-mentioned stream asset management device refusal session management equipment sends normally;
Be not more than the ultimate load of above-mentioned stream service equipment if above-mentioned present load amount minimum and service state flow bandwidth on demand sum in the present load amount of service equipment and above-mentioned stream resource points broadcast message normally, and return to the stream resource allocation result to above-mentioned session management equipment.
For example, present load amount minimum and the normal stream of service service equipment be stream service equipment 303b, and the current load capacity of stream service equipment 303b is 300M, bandwidth on demand in stream resource points broadcast message is 50M, so, (300+50) M is not more than the ultimate load 400M of stream service equipment 303b, so the stream asset management device returns to the stream resource allocation result to session management equipment.
In enforcement, the corresponding a plurality of stream service equipments of IP address possibility, so, each stream service equipment is distinguished by different ports.In this case, address information comprises IP address and port information; Suppose that the present load amount of selecting is minimum and serve normal stream service equipment is stream service equipment 303b, the address information of the associated stream service equipment 303b preserved is 10.0.64.2 and 200, and what flow that asset management device returns to session management equipment is 10.0.64.2 and 200.Wherein, 10.0.64.2 is the IP address of stream service equipment 303b, the 200th, and the port information of stream service equipment 303b.
An IP address also may corresponding 1 stream service equipment.In this case, address information only includes the IP address.The address information of supposing the associated stream service equipment 303b preserved is 10.0.64.2, and that flow that asset management device returns to session management equipment is 10.0.64.2.
