Global member Documentation

#include <fletcher_checksum.hh>

Compute a fletcher checksum

Parameters:

#include <lsa.hh>

Compare the three fields that make an LSA equivalent.

RFC 2328 Section 12.1. The LSA Header:

"The LSA header contains the LS type, Link State ID and Advertising Router fields. The combination of these three fields uniquely identifies the LSA."

#include <lsa.hh>

RFC 2328 Section 13.7. Receiving link state acknowledgments

All the fields in the header need to be compared except for the age.

#include <lsa.hh>

The definitive list of LSAs. All decoder lists should be primed using this function.

#include <lsa.hh>

Given an address and a mask generate an IPNet both of the values are in host order.

#include <lsa.hh>

Given a link state ID and a mask both in host order return a link state ID with the host bits set.

#include <ospf.hh>

Get the XRL target name.

#include <ospf.hh>

Pretty print a router or area ID.

#include <ospf.hh>

Set a router or area ID using dot notation: "128.16.64.16".

#include <ospf.hh>

Pretty print the link type.

#include <ospf.hh>

Convert from a string to the type of area

#include <ospf.hh>

Pretty print the area type.

#include <ospf.hh>

Convert from a string to the type of area

#include <packet.hh>

The definitive list of packets. All decoder lists should be primed using this function.

#include <packet.hh>

Verify the checksum of an IPv6 PDU, throw an exception if the checksum doesn't match.

In IPv6 the payload is not checksummed it is up to the protocol to checksum its own payload. The checksum includes a pseduo header that is described in RFC 2460 section 8.1

Parameters:

#include <packet.hh>

Compute the IPv6 checksum and apply it to the packet provided. If the checksum_offset is outside the packet then an exception is thrown.

In IPv6 the payload is not checksummed it is up to the protocol to checksum its own payload. The checksum includes a pseduo header that is described in RFC 2460 section 8.1

Parameters:
