  • Patent number: 10771381
    Abstract: A receiving node receives a virtual LDP initialization (vInit) message from a first node, where the vInit message comprises a request to establish a vLDP session between a requesting node and a target node. If the receiving node does not own a destination address of the vInit message, the receiving node is determined to be a relay node. The relay node inserts a relay label into the vInit message, where the relay label is an outgoing label that the relay node uses to reach the first node, and forwards the vInit message toward the destination address. If the receiving node owns the destination address, the receiving node is determined to be the target node, which extracts a stack of relay labels from the vInit message. The relay labels are used to define a return path to the requesting node for messages transmitted over the vLDP session.

  • Patent number: 10757017
    Abstract: Embodiments of the present disclosure relate to assisting forwarding of multicast traffic over Ethernet Virtual Private Network (EVPN) from a multicast source to a host multi-homed to multiple provider edge (PE) devices. Embodiments are based on the inclusion of an Ethernet Segment Identification (ESI) to EVPN type-6 routes advertised by PE devices which received a multicast Join message. Other PE devices receiving such routes are able to determine whether they belong to the ES identified by the ESI and to determine whether they are designated forwarders (DFs) for the host. Furthermore, PE devices which are the DFs are configured to re-originate the EVPN type-6 routes, i.e. re-send the advertisements, indicating themselves as DFs. This ensures that a remote PE device associated with the multicast source will also send multicast traffic to such DF PE devices, which, in turn, would allow the multicast traffic to successfully reach the host.

    Abstract: Various embodiments of the invention allow for rapid communication in virtual link trunking (VLT) networks in which network traffic flows over not all-homed VLT peer devices, while honoring Equal Cost Multi Path (ECMP) decisions and normal route decisions about next hops. Traffic flow is made deterministic and free of sub-optimal paths that otherwise cause unnecessary traffic over inter-node links in the VLT domain. In embodiments, this is accomplished by using receiving VLAN interface-IP addresses from VLT devices in order to create and use a sub-LAG egress table from which sets of ports that lead to intended VLT devices are derived. In embodiments, instead of a VLAN interface-IP addresses a routing MAC address is used when forming the sub-LAG.

  • Patent number: 10389656
    Abstract: Techniques for determining port-to-port connectivity in an extended bridge are provided. According to one set of embodiments, a port extender (PE) of the extended bridge (e.g., a base PE) can build a local database comprising connectivity information for one or more physical cascade ports of the PE. This building can be based on one or more messages received from another PE in the extended bridge (e.g., a transit PE) that is directly connected to the PE. The PE can then transmit, at a time of joining the extended bridge, the connectivity information to a controlling bridge (CB) of the extended bridge for storage thereon.

  • Patent number: 10291753
    Abstract: Methods and systems for implementing private allocated networks in a virtual infrastructure are presented. One method operation creates virtual switches in one or more hosts in the virtual infrastructure. Each port in the virtual switches is associated with a private allocated network (PAN) from a group of possible PANs. In one embodiment, one or more PANs share the same physical media for data transmission. The intranet traffic within each PAN is not visible to nodes that are not connected to the each PAN. In another operation, the method defines addressing mode tables for the intranet traffic within each PAN. The entries in the addressing mode tables define addressing functions for routing the intranet traffic between the virtual switches, and different types of addressing functions are supported by the virtual switches.
