The application discloses an SSL VPN tunnel transmission method for an IP layer, and relates to the technical field of network communication.The method constructs an IP virtual tunnel outside an SSL session, and directly encapsulates and transmits complete IP messages, thereby completely breaking through the limitation that a traditional SSL VPN only supports a Web proxy, and transparently passing through the tunnel for TCP services, UDP streaming media, ICMP network diagnostic messages, and the like, so that the method realizes remote access of the IP layer in a true sense, and a server adopts a south-north decoupling design, a virtual network port is used as a southward interface to communicate with a client tunnel, and the northward directly interacts with an intranet physical network card through a system routing table, without analyzing transport layer content, without maintaining a TCP connection state, and only performing IP layer transparent forwarding, so that the processing cost is greatly reduced, and the throughput performance is obviously improved.

The application discloses a kind of photoelectricity collaborative resource allocation method and device based on spectrum state perception, after the method receives dynamic service request, IP layer service traffic is converted into optical layer frequency slot;K-SP algorithm is filtered K alternative paths, the idle frequency slot proportion of each path link, concentration and fragment matching degree are calculated, and then the spectrum efficiency adaptation degree is obtained, the path corresponding to the maximum value is selected as working path;From the remaining path, the alternative path that meets the reservation bandwidth requirement is filtered, and the optimal protection path is selected after calculating the failure rate;When working path meets spectrum constraint, resource is distributed, and when fault, it is switched to protection path and is connected transmission.The application optimizes path selection by spectrum state accurate perception, effectively reduces spectrum fragment, improves spectrum utilization, reduces service blocking rate, enhances network reliability and dynamic adaptation ability.

The present application relates to a communication method and device. The method comprises: a terminal device receiving downlink data, wherein the downlink data carries a reverse mapping identifier; and on the basis of first-protocol-layer header information and second-protocol-layer header information of the downlink data, the terminal device generating a QoS rule for uplink data, wherein a first protocol layer comprises at least one of an IP layer, a TCP layer, and a UDP layer. The embodiments of the present application can improve the accuracy of performing QoS control over data streams.

The management and reporting of congestion in hybrid networks subject to congestion at MAC level requires adaptation of the L4S mechanism. Regarding uplink traffic, an AP receives a MAC frame marked with MAC congestion indication, reports to IP layer, the indication and the IP packet of the received frame, and responsive to the reporting, marks the packet with a CE codepoint. To speed up congestion reporting, a communication device detects congestion in a local transmit MAC queue storing MAC frames of a first flow of data traffic, and responsive to the detection, reports, to IP layer, a MAC congestion indication using a MAC service primitive. In particular, a communication device has a MAC service configured to communicate with an upper layer using a primitive that includes an ECN codepoint to report congestion and / or a MA-UNITDATA-STATUS.indication primitive that includes an ECE bit to report congestion.

The invention provides an information transmission method and device, and the method comprises the steps: an MAC layer of a first device sends a first message to an MAC layer of a second device, the first message comprises first information obtained by the MAC layer of the first device from an IP layer of the first device, and the first message is used for indicating the MAC layer of the second device to send the first information to the IP layer of the second device; the first message is transmitted through the SRI interface. Therefore, the protocol function of the SRI interface can be defined, the first information of the IP layer of the SRI interface of the first equipment can be quickly transmitted to the IP layer of the SRI interface of the second equipment, and quick interaction between the IP layer of the SRI interface of the first equipment and the IP layer of the SRI interface of the second equipment is realized.

The application relates to the technical field of communication, and discloses a multi-domain agile communication method and device, electronic equipment and a storage medium. In the application, a first neighbor beacon is periodically sent to each neighbor node, and a second neighbor beacon sent by the neighbor node is periodically received; the first neighbor beacon contains node information of each first node, and the first node at least contains the neighbor node; the second neighbor beacon contains node information of each second node; a neighbor table stored in the self is updated according to the second neighbor beacon; and network routing is established with each third node in turn by using the neighbor node. Therefore, the medium-independent network networking and path addressing functions under the condition of no center are realized. The communication efficiency reduction problem caused by the IP layer routing process is avoided. The service compatibility is good, a larger networking scale is supported, and a lower network overhead is maintained.

Provided in the present disclosure are an information transmission method and apparatus. The method comprises: a MAC layer of a first device sending a first message to a MAC layer of a second device, wherein the first message comprises first information obtained by the MAC layer of the first device from an IP layer of the first device, the first message is used for instructing the MAC layer of the second device to send the first information to an IP layer of the second device, and the first message is transmitted by means of an SRI. Therefore, an SRI protocol function can be defined, such that first information from an IP layer of an SRI of a first device can be quickly transmitted to an IP layer of an SRI of a second device, thereby implementing quick exchange between the IP layer of the SRI of the first device and the IP layer of the SRI of the second device.
