Summary:
|
As described in Y.2501, the computing power network (CPN) is a new type of network that realizes the optimized resource allocation, by distributing computing, storage, network, and other resource information of service nodes through network control plane (such as a centralized controller, distributed routing protocol, etc.). It combines network context and user requirements to provide the optimal distribution, association, transaction and scheduling of computing, storage and network resources.
The computing power network provides a reference framework for solving the resource scheduling and control of the distributed computing composed of massive computing nodes. The framework proposes to divide CPN into four layers, including CPN resource layer, CPN control layer, CPN service layer, and CPN orchestration and management layer. The resource scheduling and service provision are achieved through the interactions between the functional entities in these layers.
In the existing ITU-T items for CPN, there are several published or ongoing Recommendations about signalling architecture for each layer of CPN, such as Q.CPN-TP-SA “Signalling architecture of transaction platform in CPN”, Q.CPN-NC-SA “Signalling architecture of network control functions for CPN”, Q.4142(formerly Q.SASO)”Signalling architecture for service orchestration in computing power network”, Q.CPN-RM-SA “Signalling architecture of resource management function for CPN”. In addition, there are some items targeting signalling requirements for certain specific capabilities in computing power network, such as Q.4140 (formerly Q.CPN) “Signalling requirements for service deployment in computing power network”, Q.cpi “Signalling requirements for computing power identification in computing power network”, etc.
However, the existing ITU-T items about signalling in CPN are relatively scattered, lack a overall signalling architecture of computing power network as a standard reference, which may hard to avoid overlaps or conflicts between them.
Therefore, it is necessary to standardize signalling architecture of computing power network in ITU-T for the long-term layout and development of signalling requirements, protocols, testing specifications of computing power network. This proposal proposes to initiate a new work item on signalling architecture of computing power network.
Figure 1 shows signalling architecture of computing power network based on the CPN architecture defined in ITU-T Y.2501. It will define the signalling architecture and interface descriptions between the functional modules of different layer in computing power network.
