Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of dissemination method and device of traffic engineering attribute.
Background technology
ASON (ASON; Automatically Switched Optical Network) as the net that transmits of future generation; Compare with traditional optical transfer network; Its main feature is on light transmits the plane, to introduce control plane, with the management system of traditional optical transfer network develop into based on management plane, control is flat and and transmit the novel multi-layer facial canal reason structure on plane.Control plane is one of topmost characteristic of ASON; It uses general multiple protocols label exchange (GMPLS; Generalized Multi-Protocol LabelSwitching) protocol suite is realized, comprising LMP Link Manager Protocol, Routing Protocol and signaling protocol.Wherein, Link circuit resource is as the carrying entity of business; Be all to be vital for the data message that transmits the plane or for the signaling protocol of control plane, whether its administrative mechanism effectively directly has influence on the actual operation state of network, thus also extremely industry pay close attention to.
In order to realize the automatic foundation and the flexible dispatching of miscellaneous service, in transmitting net, can dispose the control plane technology of GMPLS usually.GMPLS is the expansion to multiprotocol label switching (MPLS, Multi-Protocol LabelSwitching), and it comprises LMP Link Manager Protocol (Link Manage Protocol), Routing Protocol and signaling protocol.LMP Link Manager Protocol obtains information such as connection type that this link supports and number of resources through message switching on the basis that syntople is found; These information are called traffic engineering (TE; Traffic Engineering) information, these links that comprise traffic engineering information are called flow engineering link.In a territory, link-local traffic engineering information is through Routing Protocol, and for example traffic engineering expansion Open Shortest Path First (OSPF-TE, Open Shortest Path First-TrafficEngineering) agreement is published to other node in the territory.Be the basis with these information; When NMS or customer requirements network are set up a network connection service; The Web portal node that connects just can carry out path computing (path computation), obtains connecting the link sequences that needs process, passes through signaling protocol then; RSVP (the RSVP-TE of traffic engineering expansion for example; ResourceReservation Protocol-Traffic Engineering), node request Resources allocation and set up interconnection on the path realizes end-to-end establishment of connection.
It is thus clear that; In ASON or GMPLS network; For the automatic supply (thereby can realize service protection and recovery fast) that realizes connecting; It is the precondition of path computing that each node has consistent TE topology information, and each node could be set up corresponding path through signaling after calculating a paths based on current TE topology information.At ASON or GMPLS network, the inventor finds that in realizing process of the present invention there is following problem at least in prior art:
Employing link bundling technology is bundled into a TE Link to many data link between two nodes and issues to the whole network.Owing to carried out the TE Link binding,, can't see the details of Member Link (data link after TE Link is bound) wherein so in route, can only see a TE Link after the binding.And after the bandwidth information of the Member Link in the TE Link changed, route need refresh corresponding TE Link information, had increased the issue frequency of route.
Perhaps, every data link is used as a TE Link issues to the whole network, this method does not reach the effect of information " compression ", and routing iinformation issue amount is bigger.
Summary of the invention
In order to overcome defective of the prior art, the embodiment of the invention provides a kind of dissemination method and device of traffic engineering attribute.
On the one hand, the embodiment of the invention provides a kind of dissemination method of traffic engineering attribute, and this method comprises: the traffic engineering TE attribute that obtains internodal many data link of the other end that this end node links to each other with link; Wherein, the TE attribute of every data link comprises the static TE attribute and dynamic TE attribute of this data link; Static TE attribute according to described many data link generates a binding TE Link, and generates respectively and this data link corresponding physical TE Link according to the dynamic TE attribute of described every data link; The attribute of issue binding TE Link and the attribute of physics TE Link; Wherein, the attribute of binding TE Link comprises at least: the corresponding relation of the sign of binding TE Link, the static TE attribute of many data link, binding TE Link and many physics TE Links; The attribute of physics TE Link comprises at least: the dynamic TE attribute of the data link of the sign of physics TE Link, physics TE Link correspondence.
On the other hand, the embodiment of the invention provides a kind of distributing device of traffic engineering attribute, and this device comprises: acquiring unit is used to obtain the traffic engineering TE attribute of internodal many data link of the other end that this end node links to each other with link; Wherein, the TE attribute of every data link comprises the static TE attribute and dynamic TE attribute of this data link; Generation unit is used for generating a binding TE Link according to the static TE attribute of described many data link, and generates respectively and this data link corresponding physical TE Link according to the dynamic TE attribute of described every data link; Release unit is used to issue the attribute of binding TE Link and the attribute of physics TE Link; Wherein, the attribute of binding TE Link comprises at least: the corresponding relation of the sign of binding TE Link, the static TE attribute of many data link, binding TE Link and many physics TE Links; The attribute of physics TE Link comprises at least: the dynamic TE attribute of the data link of the sign of physics TE Link, physics TE Link correspondence.
