Traffic Engineering Database

As defined in (Katz et al., 2003), the Traffic Engineering Database (TED) was developed from a proposal of adding more link attributes in the Opens Shortest Path First (OSPF) advertisements. The Traffic Engineering Database is in fact an extended Link Attributes Database that are built by exchange of Link State Advertising messages between routers. Some of the uses of the TED are Monitoring the extended link attributes, local constraint-based routing and global traffic engineering.
