Holding Timer The Holding Timer applies to both Configuration Information and Route Redirection Information. 2 PDU Decomposition Function This function is responsible for removing the Protocol Control Information from the protocol data unit. In this subset, the Segment Length field serves as the Total Length field of the header see. The Network entity Title would then imply which NSAPs might be present at that End system.
The entire NSAP address taken as a whole may be represented explicitly as a string of either decimal digits decimal concrete syntax or binary octets binary concrete syntax as defined below.
The technique makes use of strong variable typing to reduce ambiguity in interpretation of the specification. When a network-entity processes a PDU, it decrements the Lifetime by at least one.
If a Data PDU with the Error Report flag set to allow Error Reports is discarded for any other reason, an Error Report PDU may be generated as an implementation option.
The syntax and encoding of NPAI are defined by Network layer Protocol standards, which also specify the relationship between the NSAP address and the NPAI encoding employed by the protocol. 2 is to allow the allocation and assignment of NSAP addresses to be based on existing, well-established network numbering plans and organization-identification standards.
2 Service Conventions Definitions This document makes use of the following concepts from the OSI Service Conventions ISO 8509 : l Service user m Service provider 3.
3 Where each of the two octets of the checksum parameter has a value that is a power of two, such that only one bit in each equals one 1then a zeroing of the checksum parameter could result in an undetected double bit error.
The algorithm for producing a correct checksum value is specified in Annex A. 10 Error Reporting Function 6. In particular, it may need to influence the selection of intermediate systems to be used, and the paths to be taken between them. The list is constructed as the PDU traverses a set of interconnected subnetworks.
If insufficient space is available to store new con- figuration information, the PDU is discarded.
In essence one is simply assuming that "surely no TPDU would ever take more than 'x' seconds to traverse the network.
