Abstract: This disclosure describes techniques for implementing network address translation as a distributed service over the nodes of a logical network fabric, such as a software-defined network fabric. A method includes registering, by an edge node of a network, an IP address of a client device. The method further includes forwarding, by the edge node, the registered IP address to a control plane of the network. The method further includes checking, by the control plane, a network address translation policy. The method further includes recording, by the control plane, translations between the registered IP address and an allocated IP address in a translation table, each of the translations being related to the edge node. The method further includes returning, by the control plane, the translations between the registered IP address and the allocated IP address to the edge node.

Abstract: Techniques are described herein for service chaining in fabric networks such that hardware resources can be preserved without service nodes needing additional capabilities. The techniques may include storing a first configuration associated with a first VRF instance of a service forwarding node that is connected to a first service of a service chain sequence. The first configuration may indicate an identifier and a type associated with a second service of the service chain sequence where traffic is to be sent after the first service. Additionally, the techniques may also include storing a second configuration associated with a second VRF instance of the service forwarding node that is connected to the second service. The second configuration may indicate that the second service is a last service of the service chain sequence. When traffic is received at the service forwarding node, the service forwarding node can determine whether the traffic is pre-service traffic or post-service traffic.

Abstract: This disclosure describes techniques for software-defined service insertion. The techniques include a method of configuring a network for service insertion. The techniques include processing a master policy correlating an endpoint group pair, of source endpoint group and destination endpoint group, to a service graph. The service graph indicates a template service chain, and the template service chain indicates an ordering of a plurality of services. Processing the master policy includes disaggregating the master policy into at least one location specific policy, each of the at least one location specific policy corresponding to a separate location in the network and including traffic steering directives corresponding to a portion of the plurality of services associated with the separate location. The techniques further include causing each of the at least one location specific policy to be stored in association with the separate location to which that location specific policy corresponds.

Abstract: A method for assisting communication of a source host upon movement from a first Data center (DC) to a second DC is disclosed. The method includes identifying that the source host has moved from the first DC to the second DC, ensuring that packets identifying a source as the source host in the second DC are copied to a control plane network element, and, for a first destination host identified in a first packet copied to the control plane network element and identified as a host that is not in the second DC, updating an Address Resolution Protocol (ARP)/Neighbor Discovery Protocol (NDP) cache of the source host by sending, to the source host, a first ARP message/unsolicited neighbor advertisement specifying a Media Access Control (MAC) address of an edge router associated with the source host in the second DC as a destination MAC address for the first destination host.

Abstract: In one embodiment a method includes receiving a first message including information regarding a first host connected to a first tunnel endpoint in a first network domain, the received information being encoded in accordance with a control plane protocol of the first network domain; translating the received first message in accordance with an API and/or a database schema of a second network domain; and transmitting the translated first message to the second network domain. The method further includes receiving a second message comprising information regarding a second host connected to a second tunnel endpoint in the second network domain, the received information being encoded in accordance with the API and/or the database schema of the second network domain; translating the second received message in accordance with the control plane protocol of the first network domain; and transmitting the translated second message to the first network domain.

Abstract: This disclosure describes techniques and mechanisms for providing hybrid cloud services for enterprise fabric. The techniques include enhancing an on-demand protocol (e.g., such as LISP) and allowing simplified security and/or firewall service insertion for datacenter servers providing those services. Accordingly, the techniques described herein provide hybrid cloud services that work in disaggregated, distributed, and consistent way, while avoiding complex datacenter network devices (e.g., such running overlay on TOR), replacing and moving the functionality to on demand protocol enabled servers, which intelligently receive the required mappings as well as registers and publishes the service information to intelligently interact with the network.
