Abstract: Techniques for zero-loss workload mobility with segment routing for virtual machines are presented. The techniques include receiving, by a virtual router, an electronic message destined for a first virtual machine running on a first physical machine and checking a first virtual machine state for the first virtual machine. In response to determining that it is associated with a running state indicating the first physical machine, inserting a segment routing header including an indication of the source virtual machine, the first physical machine, and the first virtual machine. In response to determining that it is associated with a migration state, inserting, by the virtual router, a segment routing header indicating the source virtual machine, an END.S for the first physical machine, the first virtual machine; and an END.SBUF for a second physical machine. The message is then routed based at least in part on the inserted segment routing header.

Abstract: Aspects of the subject technology provide state-less load-balancing using sequence numbers to identify traffic flows. In some implementations, a process of the technology can include steps for receiving, by a load-balancer, a first packet from a source device including a request to access the service provided by a server coupled to the load-balancer, determining a load for each of the servers, wherein each server is associated with a unique set of sequence numbers, and forwarding the request to a target server selected based on its corresponding load, and wherein the request is configured to cause the target server to issue a reply to the source device. Systems and machine-readable media are also provided.

Abstract: Systems, methods, and computer-readable media for load balancing using segment routing and application monitoring. A method can involve receiving a packet including a request from a source device to an application associated with a virtual address in a network, mapping the request to a set of candidate servers hosting the application associated with the virtual address, and encoding the set of candidate servers as a list of segments in a segment routing header associated with the packet. The method can further involve determining that a first candidate server from the set of candidate servers is a next segment in the list of segments, encoding the first candidate server in a destination address field on a header of the packet, and forwarding the packet to the first candidate server.

Abstract: A method of delivering content in one or more packets over a network is described. A content request packet comprising a request for content based on a first IPv6 address is received, the first IPv6 address identifying the content. The first IPv6 address is mapped to a second IPv6 address, the second IPv6 address being associated with the content at a physical location. The content requested in the content request packet is then received from the physical location associated with the second IPv6 address for delivery to a user. A further method includes routing a packet for requesting the content from a client to a content server storing an instant of the content, based on an IPv6 address of content being requested by the client. A communication session is then set up between the client and the content server; and the requested content is transmitted from the content server.

Abstract: Disclosed is a method that modifies a bit indexed explicit replication (BIER) algorithm. The method includes receiving a packet at a node, wherein the packet includes a BIER header identifying a bitstring, the bitstring including a first bit indicating a first destination and a second bit indicating a second destination and forwarding the packet through one or more networks toward the first destination and the second destination based on the bitstring and a predetermined bit selection order. The predetermined bit selection order causes a sequential delivery of the packet to the first destination and the second destination. After the packet arrives at the first destination, the method includes setting the first bit to zero in the bitstring and forwarding the packet through the one or more networks toward the second destination according to the updated bitstring.
