Patent number: 11956141Abstract: Techniques are described in which a centralized controller, such as a software defined networking (SDN) controller, constructs a service chain that includes a physical network function (PNF) between a bare metal server (BMS) and a virtual execution element (e.g., virtual machine or container), or in some instances a remote BMS, or vice-versa. In accordance with the techniques disclosed herein, the controller may construct an inter-network service chain that includes PNFs, or a combination of PNFs and virtualized network functions (VNFs). The controller may construct an inter-network service chain to steer traffic between a BMS and a virtual execution element or remote BMS through an inter-network service chain using Virtual Extensible Local Area Network (VXLAN) as an underlying transport technology through the service chain.Type: GrantFiled: April 7, 2023Date of Patent: April 9, 2024Assignee: Juniper Networks, Inc.Inventors: Mahesh Sivakumar, Anantharamu Suryanarayana, Ankur Tandon

Patent number: 11632354Abstract: A disclosed method is performed at a first boundary node bordering a BIER domain. The method includes receiving a message associated with a source and group for multicast from outside the BIER domain. The method further includes generating an encapsulated message based on the message, a metric, and a first proxy address of the first boundary node. The method also includes forwarding the encapsulated message through the BIER domain to at least one second boundary node bordering the BIER domain and connectable to the first boundary node. The first boundary node additionally triggers the at least one second boundary node to decapsulate the encapsulated message for forwarding out of the first domain and store a record including the source, the group, the metric representing the cost of the first boundary node to the source, and the first proxy address on the at least one second boundary node.Type: GrantFiled: August 30, 2018Date of Patent: April 18, 2023Assignee: Cisco Technology, Inc.Inventors: Stig Ingvar Venaas, Mahesh Sivakumar, Ijsbrand Wijnands, Mankamana Prasad Mishra
