Systems and methods that allow a multihomed gateway to monitor its membership in individual domains in an Ethernet Virtual Private Network (EVPN) Data Center Interconnect (DCI) Network, and issue withdrawals from multihoming groups associated with those domains based on this membership, are disclosed. According to embodiments, links between a local domain and a gateway, and between the gateway and a remote domain, can be monitored at the gateway. When the link between the gateway and a domain goes down the gateway may withdraw itself from any multihoming group associated with the domain to which the link has been lost.

A method for providing stream control transmission protocol (SCTP) multihoming between a Kubernetes environment and a non-Kubernetes environment includes receiving, at an SCTP multihoming router (SMR) deployed as a pod within the Kubernetes environment and from a client in the non-Kubernetes environment, an SCTP INIT message for establishing a multi-homed SCTP association between first and second Internet protocol (IP) addresses of the client and first and second local IP addresses of the SMR. The first and second local IP addresses of the SMR are added to an SCTP header of the SCTP INIT message. Source and destination network address translations (NATs) are performed to change a source IP address and a destination IP address in an IP header of an IP datagram carrying the SCTP INIT message to a third local IP address of the SMR and a service IP address of a service in the Kubernetes environment, respectively.

Existing Equal Cost Multi-path (ECMP) grouping strategies in a multi-homing network have scalability issues due to limited hardware resources. To address this, devices, systems, methods, and processes for adaptive optimization of ECMP groups are described herein. An optimization logic, coupled to a plurality of network devices, receives a set of route advertisements of the plurality of network devices and allocates a shared ECMP group, including two or more network devices of the plurality of network devices, for at least two ESs based on the set of route advertisements. A next hop list is generated in which the at least two ESs point to the shared ECMP group. The optimization logic may update the next hop list based on link failures or route withdrawal advertisements associated with the two or more network devices included in the shared ECMP group. The ES may be removed from pointing to the shared ECMP group.

A system and method are provided for faster convergence with multihoming using internet protocol (IP) performance measurement (PM) sessions to report, to a transmitting provider edge (PE), a state of health of a connection between a multihomed node and a receiving (PE). The state of health can be the liveness of the connection. The receiving PE locally monitors the state of health of its connection to the node, and encodes information of the state of health in a field of the PM session messages sent to the transmitting PE. For example, while the PM session messages indicate the connection is live, traffic from the transmitting PE to the node is routed through the receiving PE. Upon the PM session messages indicating the connection is no longer live, the transmitting PE instead routes traffic to the node through another receiving PE with which the node is multihomed.

Devices, networks, systems, methods, and processes for tracking a multi-homed host device are provided herein. A communication network may include at least two network devices and a host device that is multi-homed to the at least two network devices. A network device of the at least two network devices transmits a first tracking request to the host device and receives a tracking response for the first tracking request at a network-side interface of the network device. The first tracking request includes a first data sequence. The network device transmits, based on receiving the tracking response at the network-side interface, one or more second tracking requests with varying second data sequences in an attempt to force a response from the host device at a host-side interface of the network device. Thus, the host device is tracked in an efficient manner without changing a hashing algorithm of the host device.

Methods and systems for scaling energy consumption in wireless network infrastructure, while retaining the ability to quickly scale when load changes. This end is accomplished by using containerized (or virtualized) applications to implement 5G core Network Functions, and utilizing network redundancy / geo-redundancy or a multihoming transport protocol for communication between these containerized (or virtualized) applications and other 5G system elements such as the network functions of the Radio Access Nodes (RANs) or the network functions of 5G Core. In particular, one or more core Network Functions (NFs) are instantiated as containerized applications executing on one or more virtualized hosts in a cloud-native orchestration environment. The containers are selectively activated or deactivated based on a demand for utilization of the associated NF. Because elements of the 5G RAN, 5G Core and one or more NFs are connected to one another via a protocol that supports network redundancy and / or geo-redundancy and / or multihoming, endpoint addressing need not be reconfigured when demand on the NFs changes.

Techniques and architecture are described for L2 service insertion in a network. More particularly, the techniques and architecture provide for monitoring a L2 service, e.g., firewall, MAC address (instead of learning the MAC address) and registering / de-registering the service node (e.g., fabric border or edge or LISP service_etr) to the service control plane (e.g., LISP MSMR) based on this. This not only load-balances the traffic (per L2 flow) but also tracks it for node's liveliness. The techniques and architecture also provide L2 service insertion connected to a service border to allow for dynamic SGT based service, e.g., firewall, insertion for both software defined access (SDA) fabric and non-fabric deployments.

Devices, networks, systems, methods, and processes for synchronizing a port property in a multi-homed communication network for multicasting are provided herein. The multi-homed communication network may include peer network devices and a host device that is multi-homed to the peer network devices. If a port of a network device of the peer network devices is coupled to a multicast source via the host device, the network device may update the port property of its port.

Accordingly, if the network device fails to transmit a multicast join message for a multicast query message, the forwarded notification message may configure the peer network device to act as a proxy for the network device to forward the multicast query message.
