Embodiment
The object of the invention is in OSPF and ISIS network environment, according to network topological information and the stream information collected, data correlation can be carried out, the result of the topological sum data on flows fusion of accurate, real-time reflection network.
The module that the present invention relates to has message acquisition module, route topological parsing module, flow collection module, routing traffic analysis module.
Concept wherein in the present invention is: neighbor node: the neighbours that each topological node is all; Stub zone: the subnet region hung under border router; Borderline region: the all-router be connected with other territories; Interior zone set: the result of inventory analysis neighbor node; Prefix regions is gathered: the result of inventory analysis stub zone; Borderline region set: the result of inventory analysis borderline region.
Be below concrete steps of the present invention, as follows:
The data correlation of OSPF topology and flow, OSPF message acquisition module sets up peering session by a router in region each in tunnel and autonomous system, realizes the collection of message, gets the network route information of OSPF.OSPF topology concatenation module according to routing iinformation, can splice current network topology, then issues routing resolution module.Whole network topology is resolved, point three stepping row relax after OSPF routing resolution module receives network topology, as follows:
The first step, analyzes neighbor node.Progressively analyze each node in network topology, according to the neighbor information of each node, neighbours' interface IP information and this neighbor router ID are bound and is stored in interior zone set;
Second step, analyzes stub zone (STUB).In stub area, analyze and preserve each route corresponding be this route prefix and mask phase and the network segment in Prefix regions is gathered;
3rd step, analyzes the borderline region (ASBR) of router.Border routing is analyzed and the route of preserving the down hop of border router IP and the outside AS of border routing in borderline region set.
After having analyzed network topology, routing resolution module has started to receive the stream (NETFLOWV9 form) that flow collection module is sent, and then combines the topological data just analyzed and processes.
For a process wherein stream, resolve in the information getting this stream and comprise source IP, source mask, object IP and object mask, as follows:
(1) find source router ID to judge whether to have in interior zone set and comprise router id corresponding to this source IP, if had, directly return results; If no, jumped to (2);
(2) by source IP and source mask phase with, obtain inquiry in the set of Prefix regions after the prefix of source, if had, directly return results; If no, jumped to (3);
(3) source IP is used to obtain in the border router of ASBR borderline region and down hop.Return Query Result.If inquire about less than, then may non-ospf network flow.
Find object router identical with source router method.
The data correlation of ISIS topology and flow, ISIS message acquisition module, by the collection to LSP message, can get the routing iinformation of ISIS network.Topology concatenation module according to routing iinformation, can splice current network topology, then issues routing resolution module.Routing resolution module resolves network topology after receiving network topology, processes in two steps, as follows:
The first step: analyze neighbor node region.Progressively analyze each node in network topology, according to the neighbor information of each node, store this neighbours' link information, and this node SystemID (system identifier) is stored in interior zone set with RouteID (router id) correspondence relationship information.
Second step: analyze the intermediate router IP in level1 region and level2 region in the mapping Reachability regional ensemble of router id, and the correspondence relationship information of SystemID to RouteID all for this region is stored in zone line set.
After having analyzed network topology, routing resolution module has started to receive the stream (NETFLOWV9 form) that flow collection module is sent, and then combines the topological data just analyzed and processes.
For a process wherein stream, resolve in the information getting this stream and comprise source IP, source mask, object IP and object mask.
(1) according to source router IP and object accessor, judge whether source router IP and object accessor are present in interior zone set.If existed, directly return RouteID and SystemID that source router IP is corresponding with object accessor.If there is no, then jump to (2);
(2) then go to search this RouteID (router id) in Reachability regional ensemble (Reachability regional ensemble is the mapping set of the IP routers ID of the router of borderline region), if all there is this RouteID in all Reachability regional ensembles, then find the object router of the minimum router of declaration metric value as one's respective area; There is this RouteID information if only had in part Reachability regional ensemble, then find router according to the longest coupling of network prefix.
CD (CachingDijkstra) algorithm, in conjunction with CD algorithm, obtain source router information, object route-map, intermediate router information, because what in ospf network be is shortest path first, so the beeline in network topology between router is analogized to the beeline of the point-to-point of figure by us.
Algorithm safeguards two vertex set S and Q.The value that S set remains we known all d [v] has been the value summit of shortest path, gathers Q and then retains other all summits.S set initial condition is empty, and then each step has a summit to move to S from Q.This is the summit having minimum d [u] value in Q by the summit selected.When a summit u has transferred in S from Q, algorithm is expanded the outer edge fit (u, v) of every bar.
By retaining the shortest path from s (source node) to v found so far for each vertex v (destination node), removing double counting, reducing time complexity.Time initial, the path length value of source point s is 0 (d [s]=0 by tax, d [s] is for source point is to the beeline of destination node s), if there is the limit (s that can directly arrive, m), then d [m] is set to w (s, m), the path on every other (s can not directly arrive) summit is set to infinity simultaneously, namely represents that we do not know any path (for d [the v]=∞ except s and above-mentioned m of all vertex v in G (figure)) leading to these summits.When algorithm exits, what store in d [v] is shortest path from s to v, if or the non-existent words in path be infinitely great.The fundamental operation of Dijkstra's algorithm is the expansion on limit: if there is a limit from u to v, the shortest path so from s to v can by adding afterbody to expand a path from s to v by limit (u, v).The length of this paths is d [u]+w (u, v).If this value is less than the value of d [v] known at present, we can carry out the value in alternative current d [v] by new value.The operation of expanding limit runs to the cost that all d [v] represent the shortest path from s to v always.This algorithm through organizing thus when d [u] reaches its final value time every bar limit (u, v) all only expanded once.
Composition graphs 1 introduces the analytic process of CD algorithm:
spf{A},candidate{B:6,C:3,D:∞,E:∞,F:∞}
spf{A,C}candidate{B:5,D:6,E:7,F:∞}
spf{A,C,B}candidate{D:6,E:7,F:∞}
spf{A,C,B,D}candidate{E:7,F:9}
spf{A,C,B,D,E}candidate{F:9}
spf{A,C,B,D,E,F}
In conjunction with above-mentioned analytical procedure, we can find to safeguard two set in analytic process---spf array and candidate array, be called " mirror image " (saving the information of the state that current algorithm is run) of this CachingDijkstra, and (namely in the source that have found this stream at the end of each analytic process, destination path), all with source router id for key, " mirror image " is a for value preserves in main thread to be mapped.Like this when analyzing the path that this source starts next time, just directly can be loaded into " mirror image " that last analytic process is preserved, continuing on this basis to analyze, so just avoiding double counting well.Above map analysis process is example: analyze A---the path of D, but only analyzed A before---the path between B, therefore A is not had in buffer memory---the path of D, this situation needs with A to be that CD algorithm is run in source, before initialization spf and candidate array, so first searches in main thread the analysis " mirror image " that whether to have had with this source be root, if had, with " mirror image " initialization these two set, continue to calculate, for this example, be loaded with:
“2.spf{A,C,B}candidate{D:6,E:7,F:∞}”
As long as rerun on this basis, a step can obtain path.In order to improve the speed of service, this method have employed the thought of space for time.
Be below one embodiment of the invention, as shown in Figure 2:
For OSPF: in the ospf network of single AS, by the message in OSPF message acquisition module collection network, topology concatenation module is according to the message collected, splice the topology in network and send to routing resolution module, routing resolution module is resolved topological analysis and is gone out router id corresponding to each IP, calculate the shortest path between every two routers simultaneously, after receiving the stream information that flow collection module sends over, network topology and stream information are also carried out data correlation by resolution flow information, get the result of data fusion, shown according to this result by display module.
