Hi Tanxin, Sorry for late replay. Below are the answers to your questions:
1. This draft proposes a fast notification packet used in scenarios such as congestion notification and failure notification. In which layer does this packet work, or is it a universal packet applicable to various protocols like [draft-shi-ippm-congestion-measurement-data]? [Haibo] The notification packet is a new individual message encapsulated in UDP and operates at the network layer. It can serve as a common notification message for different use cases. However, it differs from the packet described in [draft - shi - ippm - congestion - measurement - data]. In the IPPM draft, no new packet is used; instead, measurement information is inserted directly into the data packet. 2. This draft analyses the mechanisms of adaptive routing. Can you provide a more detailed workflow about the proposed packet to help with understanding? [Haibo] Adaptive routing is a data-plane mechanism that is highly sensitive to fast congestion and enables switching. Here is a more detailed breakdown of the process: Local Adaptive Routing: A Forwarding Information Base (FIB) may have multiple output ports. When traffic arrives, it selects one of the output ports for forwarding. However, if the chosen output port becomes congested, the system can quickly switch to another non - congested output port. This is known as local adaptive routing. Remote Adaptive Routing: When a boundary network device detects congestion on its output ports, it constructs a notification message and sends it to the inner network devices. Upon receiving this message, the inner network devices are informed that the boundary network device is experiencing congestion. Subsequently, they can perform remote adaptive routing for the affected path. 3.The content of this draft is within the scope of Fantel, is it possible to discuss this draft in the Fantel mailing list? [Haibo] Yes, you are most welcome to initiate a discussion about it on the Fantel mailing list.
