openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Freezing is a technique for halting and checkpointing packet translation in
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * a way that it can be restarted again later. This file has a couple of data
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * structures related to freezing in general; their names begin with "frozen".
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Recirculation is the use of freezing to allow a frame to re-enter the
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * datapath packet processing path to achieve more flexible packet processing,
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * such as modifying header fields after MPLS POP action and selecting a slave
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * port for bond ports.

openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Recirculation uses two uint32_t fields, recirc_id and dp_hash, and a RECIRC
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * action. recirc_id is used to select the next packet processing steps among
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * multiple instances of recirculation. When a packet initially enters the
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * datapath it is assigned with recirc_id 0, which indicates no recirculation.
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Recirc_ids are managed by the user space, opaque to the datapath.
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * On the other hand, dp_hash can only be computed by the datapath, opaque to
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * the user space, as the datapath is free to choose the hashing algorithm
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * without informing user space about it. The dp_hash value should be
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * wildcarded for newly received packets. HASH action specifies whether the
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * hash is computed, and if computed, how many fields are to be included in the
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * hash computation. The computed hash value is stored into the dp_hash field
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * prior to recirculation.
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * The RECIRC action sets the recirc_id field and then reprocesses the packet
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * as if it was received again on the same input port. RECIRC action works
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * like a function call; actions listed after the RECIRC action will be
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * executed after recirculation. RECIRC action can be nested, but datapath
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * implementation limits the number of nested recirculations to prevent
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * unreasonable nesting depth or infinite loop.

openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * ==========================
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Freezing is a technique for halting and checkpointing packet translation in
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * a way that it can be restarted again later. This file has a couple of data
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * structures related to freezing in general; their names begin with "frozen".
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Recirculation is the use of freezing to allow a frame to re-enter the
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * datapath packet processing path to achieve more flexible packet processing,
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * such as modifying header fields after MPLS POP action and selecting a slave
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * port for bond ports.
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Data path and user space interface
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * -----------------------------------
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Recirculation uses two uint32_t fields, recirc_id and dp_hash, and a RECIRC
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * action. recirc_id is used to select the next packet processing steps among
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * multiple instances of recirculation. When a packet initially enters the
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * datapath it is assigned with recirc_id 0, which indicates no recirculation.
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Recirc_ids are managed by the user space, opaque to the datapath.
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * On the other hand, dp_hash can only be computed by the datapath, opaque to
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * the user space, as the datapath is free to choose the hashing algorithm
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * without informing user space about it. The dp_hash value should be
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * wildcarded for newly received packets. HASH action specifies whether the
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * hash is computed, and if computed, how many fields are to be included in the
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * hash computation. The computed hash value is stored into the dp_hash field
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * prior to recirculation.
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * The RECIRC action sets the recirc_id field and then reprocesses the packet
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * as if it was received again on the same input port. RECIRC action works
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * like a function call; actions listed after the RECIRC action will be
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * executed after recirculation. RECIRC action can be nested, but datapath
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * implementation limits the number of nested recirculations to prevent
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * unreasonable nesting depth or infinite loop.

openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- *
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h- * Recirculation is usually hidden from the OpenFlow controllers. Action
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * translation code deduces when recirculation is necessary and issues a
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * datapath recirculation action. All OpenFlow actions to be performed after
openvswitch-2.9.0/ofproto/ofproto-dpif-rid.h: * recirculation are derived from the OpenFlow pipeline and are stored with the

openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- *
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * The use cases for freezing are:
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- *
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * - "Recirculation", where the translation process discovers that it
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * doesn't have enough information to complete translation without
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * actually executing the actions that have already been translated,
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * which provides the additionally needed information. In these
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * situations, translation freezes translation and assigns the frozen
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c: * data a unique "recirculation ID", which it associates with the data
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * in a table in userspace (see ofproto-dpif-rid.h). It also adds a
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * OVS_ACTION_ATTR_RECIRC action specifying that ID to the datapath
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * actions. When a packet hits that action, the datapath looks its
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * flow up again using the ID. If there's a miss, it comes back to
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c: * userspace, which find the recirculation table entry for the ID,
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * thaws the associated frozen data, and continues translation from
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * that point given the additional information that is now known.
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- *
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * The archetypal example is MPLS. As MPLS is implemented in
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * OpenFlow, the protocol that follows the last MPLS label becomes
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * known only when that label is popped by an OpenFlow action. That
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * means that Open vSwitch can't extract the headers beyond the MPLS
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * labels until the pop action is executed. Thus, at that point
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c: * translation uses the recirculation process to extract the headers
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * beyond the MPLS labels.
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- *
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * (OVS also uses OVS_ACTION_ATTR_RECIRC to implement hashing for
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * output to bonds. OVS pre-populates all the datapath flows for bond
openvswitch-2.9.0/ofproto/ofproto-dpif-xlate.c- * output in the datapath, though, which means that the elaborate
