COMPRESSING SEGMENT IDENTIFIERS FOR SEGMENT ROUTING
20230040043 · 2023-02-09 ·

A method implemented by a first node in a segment routing (SR) network domain includes receiving, from a second node of another network domain, a packet configured to pass through the SR network domain in accordance with segment identifiers (SIDs). The method also includes obtaining compressed SIDs corresponding to some of the SIDs. The method includes generating a segment routing header (SRH) having a list of segments. The method further includes adding the SRH to the packet and forwarding the packet with the SRH to a third node in the SR network domain.

IN-SITU FLOW DETECTION-BASED PACKET PROCESSING METHOD AND APPARATUS
20230045227 · 2023-02-09 ·

Embodiments of this application describe an in-situ flow detection-based packet processing method. After receiving a first packet encapsulated by using a first bearer protocol, a first node may obtain, based on the first packet, a second packet encapsulated by using a second bearer protocol. A first packet header of the first packet includes first in-situ flow detection information, and a packet header of the second packet also includes the first in-situ flow detection information. It can be learned that, when re-encapsulating the first packet by using the second bearer protocol, the first node does not remove the first in-situ flow detection information, but adds the first in-situ flow detection information to the packet encapsulated by using the second bearer protocol. Therefore, even if the first bearer protocol and the second bearer protocol are deployed in a detection domain, the first in-situ flow detection information is not removed due to re-encapsulation of the packet, and may be transmitted across the entire detection domain.

INTELLIGENT FLOW STATE SYNCHRONIZATION TO IMPROVE RESILIENCY, AVAILABILITY, AND/OR PERFORMANCE OF REDUNDANT NETWORK SECURITY DEVICES
20230037516 · 2023-02-09 ·

Example security systems for use between at least one upstream router and at least one downstream router, are described. A group or pool of security devices can be used to provide stateful security to bidirectional packet flows between upstream and downstream routers. The packets of the bidirectional flows are forwarded to particular security devices based on a consistent hash ring process. For a given flow, bidirectional state information is synchronized among some, but not all, of the security devices. The security devices among which such bidirectional flow state information is shared are determined using the same consistent hash ring process.

Scalable and programmable mechanism for targeted in-situ OAM implementation in segment routing networks

The present technology provides a system and method for implementing targeted collection of in-situ Operation, Administration and Maintenance data from select nodes in a Segment Routing Domain. The selection is programmable and is implemented by setting an iOAM bit in the function arguments field of a Segment Identifier. In this way only the nodes associated with local Segment Identifiers (Function field of a Segment Identifier) with an iOAM argument bit are directed to generate iOAM data. The iOAM data generated by target nodes may be stored in TLV field of the segment routing header. The Segment Routing packet is then decapsulated at a Segment Routing egress node and the Header information with the collected iOAM data is sent to a controller entity for further processing, analysis and/or monitoring.
