Abstract: Disclosed are a method and a device for automatically implementing IOAM encapsulation, and a storage medium. The method comprises: sending, at an IOAM ingress node, a first message carrying IOAM configuration request information to an IOAM centralized configuration point; receiving, at the IOAM ingress node, a second message carrying IOAM configuration information of IOAM transmission nodes sent from the IOAM centralized configuration point; and performing, at the IOAM ingress node, IOAM encapsulation on a service data message according to the IOAM configuration information of the IOAM transmission nodes.

Abstract: The present disclosure relates to an information processing method, comprising: encapsulating, in a link layer discovery protocol data unit (LLDPDU), bit indexed explicit replication (BIER) bit string length information of a first node; and sending to a second node the LLDPDU, wherein the second node is an adjacent node of the first node, and the BIER bit string length information of the first node is used to forward BIER traffic. The present disclosure also relates to an information processing device.

Abstract: Disclosed is a method and system for encapsulating a flow identifier. The method for encapsulating a flow identifier comprises: in the case where flow table matching is successfully performed on a packet, an OpenFlow switch adds a flow identifier to the packet; and the OpenFlow switch invokes a pre-saved function entry to assign a value to the flow identifier, so as to complete the encapsulation of the flow identifier. The disclosure achieves the effect of enabling an OpenFlow network node to take a hash calculation result of some fields of an original packet before encapsulation as the assignment of a new added flow identifier, which is required by the encapsulation of the flow identifier.

Abstract: Provided are a method and device for processing a Graceful Restart (GR) of an OpenFlow switch, and an OpenFlow controller. The method includes that: the OpenFlow switch is determined being in a GR state; and the state of the OpenFlow switch is marked as the GR state, wherein marking the state as the GR state includes: keeping a flow table and external connection of the OpenFlow switch before GR still valid, and prohibiting the flow table from being modified. Through the present disclosure, the problem in the related art that GR of an OpenFlow switch cannot be achieved is solved, thereby achieving the effect of effectively implementing the GR of the OpenFlow switch.

Abstract translation: 公开了一种封装流标识符的方法和系统。 用于封装流标识符的方法包括：在对分组成功执行流表匹配的情况下，OpenFlow交换机向分组添加流标识符; OpenFlow交换机调用预先保存的功能表项为流标识符分配一个值，从而完成流标识符的封装。 该公开内容实现了使OpenFlow网络节点在封装之前采用原始分组的某些字段的哈希计算结果作为流标识符的封装所需的新的附加流标识符的分配的效果。
