Examples with SRLinkWeigher org.onosproject.segmentrouting.SRLinkWeigher used on opensource projects

Example 1 with SRLinkWeigher

use of org.onosproject.segmentrouting.SRLinkWeigher in project trellis-control by opennetworkinglab.

the class DefaultL2TunnelHandler method getPath.

/**
 * Returns the path betwwen two connect points.
 *
 * @param srcCp source connect point
 * @param dstCp destination connect point
 * @return the path
 */
private List<Link> getPath(ConnectPoint srcCp, ConnectPoint dstCp) {
    // use SRLinkWeigher to avoid pair links, and also
    // avoid going from the spine to the leaf and to the
    // spine again, we need to have the leaf as CP1 here.
    LinkWeigher srLw = new SRLinkWeigher(srManager, srcCp.deviceId(), new HashSet<Link>());
    Set<Path> paths = srManager.topologyService.getPaths(srManager.topologyService.currentTopology(), srcCp.deviceId(), dstCp.deviceId(), srLw);
    log.debug("Paths obtained from topology service {}", paths);
    // We randomly pick a path.
    if (paths.isEmpty()) {
        return null;
