Data messages such as data packets in an IPv4 or IPv6 format are processed with a view to compression/decompression, using information obtained from sources other than the data packet itself, or the stream to which it belongs. This may involve additional dynamic processing defined in specifications identified by a shared marker, or obtained from an additional data source such as a static file, database application or the like. Embodiments described herein enhance this approach with a dynamic determination of data components.

A method for compressing is provided. The method includes compressing, via a processor, a portion of a first data packet to generate a second data packet having a compressed portion. The method includes transmitting the second data packet having the compressed portion via an interface to a co-processor. The processor and the co-processor are communicatively coupled via the interface. The method also includes unpacking, via the co-processor, the compressed portion of the second data packet to restore the first data packet.

Methods and devices for providing routing path and transit delay time data to a device running traceroute on an IP network comprising routing tunnels are described herein. In examples, a tunnel entrance device may copy a hop limit value associated with a traceroute probe into a hop limit field of a tunneled IP header. In other examples, the tunnel entrance device may perform address spoofing to generate an error message with a source address corresponding to an intermediate device disposed within a routing tunnel. In this way, a device executing traceroute may be able to receive network addresses corresponding to intermediate devices in a routing tunnel in order to perform network diagnostics, construct routing tables, determine more efficient routing paths, and so on.

This disclosure provides a data sending method and receiving method, and user equipment thereof, and relates to the field of communications technologies. The data receiving method applied to user equipment includes: determining whether a Medium Access Cntrol (MAC) Protocol Data Unit (PDU) received by the user equipment includes a reserved Logical Channel Identity (LCID) value; and when the MAC PDU includes a reserved LCID value, discarding a Service Data Unit (SDU) or sub-PDU corresponding to the reserved LCID value in the MAC PDU.

Provided is an information transmission method and apparatus. The method includes: in an IAB scenario, an integrated access and backhaul (IAB) node acquiring a first data packet; and a first IAB node sending the first data packet to an IAB donor. Further provided are an information acquisition method and apparatus, a storage medium and an electronic apparatus.
