INSTANCE-AFFINE SERVICE SCHEDULING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18534222 titled 'INSTANCE-AFFINE SERVICE SCHEDULING

Simplified Explanation

The routing device described in the patent application is designed to efficiently handle packets in a flow of packets to one or more instances of a service function. Here is a simplified explanation of the abstract:

  • The controller of the routing device sets up forwarding states for packets in a flow to direct them to specific instances of a service function.
  • If a received packet does not match the established forwarding state, a new forwarding state is created to direct it to the appropriate service function instance.
  • The device then prepares to send the packet to the next hop based on the established forwarding state.
  • If the received packet matches the established forwarding state, it is prepared to be sent to the next hop accordingly.
      1. Potential Applications

- Network routing optimization - Service function chaining in data centers

      1. Problems Solved

- Efficient packet handling in a flow of packets - Dynamic establishment of forwarding states for service function instances

      1. Benefits

- Improved network performance - Enhanced scalability in data center environments

      1. Potential Commercial Applications
        1. Optimizing Network Routing for Service Function Chaining
      1. Possible Prior Art

There are existing technologies in the field of network routing and service function chaining that may have similarities to the described routing device. One example is the use of software-defined networking (SDN) controllers to manage network traffic and direct packets to specific service function instances.

        1. Unanswered Questions
        2. How does the routing device handle packet loss or network congestion?

The patent application does not provide details on how the routing device addresses packet loss or network congestion issues that may arise during packet forwarding.

        1. What security measures are in place to protect the routing device from potential cyber threats?

The abstract does not mention any specific security features or protocols implemented in the routing device to safeguard it from cyber threats.


Original Abstract Submitted

A routing device includes a controller configured to establish a first forwarding state for an initial packet of a flow of packets to one or more of a plurality of instances of a service function and receive a packet of the flow of packets. If the received packet does not match a second forwarding state for subsequent packets of the flow of packets, the routing device establishes the second forwarding state to a particular one of the one or more of a plurality of instances of the service function, and prepares to send the received packet to a next hop in accordance with the first forwarding state. If the received packet matches the second forwarding state, the routing device prepares to send the received packet to the next hop in accordance with the second forwarding state.
