摘要：Methods and apparatus are disclosed for obtaining information from a predetermined portion of a header of a data item such as an IP packet transmitted via a communication network such as a packet network, the portion carrying a codepoint selected from a first set of codepoints each of which has a pre-defined meaning according to a first pre-defined communication protocol. The method comprises: receiving the data item (s71); inspecting the header whereby to determine the codepoint carried by the predetermined portion thereof (s72); identifying whether the codepoint is a member of a second set of codepoints (s77, s78), the second set comprising fewer possible codepoints than the first set; and in the event that the codepoint is identified as being a member of the second set, and in dependence on such an identification being made, interpreting that codepoint according to a different pre-defined communication protocol as having a different pre-defined meaning (s80).
