  • Patent number: 10999126
    Abstract: Techniques are described for avoiding traffic black-holing in a multi-homed Ethernet virtual private networks (EVPNs) in which a customer device (CE) is multi-homed to a plurality of multi-homing provider edge devices (PEs) via respective links of an Ethernet segment. An overlay network is created over the Ethernet segment, and the multi-homing PEs of the EVPN are configured with a common anycast IP address for respective virtual network interfaces. Upon election as active designated forwarder (DF) for the EVPN, the DF PE of the multi-homing PEs advertises toward the customer network an IGP metric for the anycast IP address that is lower than the IGP metric(s) advertised by any of the non-DF standby PE routers segment to direct the CE to forward network packets from the customer network to the DF PE over the respective link of the Ethernet segment.

  • Patent number: 10986018
    Abstract: For managing a traffic overload in a software defined network having an SDN controller, when an indication of a traffic overload is received, there are steps of identifying traffic flows which contribute to this, identifying nodes of the network controllable by the SDN controller and located along a path of the identified traffic flows before the location of the traffic overload. The SDN controller is used to control the identified nodes to control the identified traffic flows to reduce the traffic overload. By using the SDN controller to control the reduction compared to diverting suspicious traffic flows to a separate external security server, the extra network resources used for carrying the diverted traffic flows are not needed, the separate security server is not needed, and the risk of such diverted traffic flows themselves causing overloads is reduced. It can be applicable to a range of causes of overload, including denial of service attacks.

  • Patent number: 10959285
    Abstract: A method, performed by a gateway node (110), for managing packets on a transport connection between a first end-point (120) and a second end-point (130) is disclosed. The gatewaynode (110) forwards (A020), on the transport connection (105), a first packet from the first end-point (120) to the second end-point (130). The gateway node (110) finds (A040), by inspection of the first packet, that the first packet indicates closing of the transport connection (105) at the first end-point (120). Moreover, the gateway node (110) receives (A120) after the finding (A040), on the transport connection, a second packet from the second end-point (130), wherein the second packet is destined to the first end-point (120). Furthermore, the gateway node (110) discards (A130) the second packet, thereby refraining from forwarding, on the transport connection, the second packet from the second end-point (130) to the first end-point (120). A gateway node (110), a computer program and a computer program carrier are also disclosed.
