RON ( Routed Optical Networking )

Posted on by lechuck park

From Claude with some prompting
This image provides an overview of Routed Optical Networking (RON), which is a networking technology that combines IP routing and MPLS with wavelength multiplexing to enable very long distance data transmission.

The key features highlighted in the image are:

  1. Network simplification: RON reduces the complex hierarchy of routers and transmission equipment traditionally used in optical networks.
  2. Cost-effectiveness: RON eliminates the need for separate transmission equipment, reducing hardware and maintenance costs.
  3. Reduced latency: Data is processed within a single device, rather than going through multiple devices, reducing latency.
  4. Operational efficiency: Routing and transport functions are consolidated, allowing the network to be managed from a single management platform.

The image also shows the main components of a RON system, including IP routing + MPLS, wavelength multiplexing, L3 layer, physical layer, router, and DWDM (Dense Wavelength Division Multiplexing). It also lists some specific technologies used, such as IP over Dense, Wavelength Division Multiplexing (Juniper) and Photonic Service Engine (Nokia).

Overall, this diagram illustrates how RON simplifies optical networking by combining multiple networking functions into a more efficient and cost-effective architecture.Copy

All are by packets

From Claude with some prompting
Let me explain this network diagram which illustrates packet processing and various network devices:

  1. Network Components:
  • Internet: Shows L3-L7 packet flowing
  • Router: Handles L3 routing and packet control
  • Firewall/IPS/IDS: Manages L3/L4 base packet control and L7 packet analysis/control
  • Switching: Performs Ethernet(L2/L3) switching and L2/L3 packet control
  • Server/Client: Handles packet send & receive (L1-L7), packet making and analysis
  1. Key Issues:
  • COST Concerns:
    • ALL operations are packet-based
    • Performs L1-L7 packet collecting/analysis/switching/routing
    • Multiple devices perform many duplicates of the same functions (L2, L3-L4 packet collecting/analysis/switching/routing)
  1. Suggested Improvement:
  • Mentioned in “IF Possible” section:
    • Consider aggregating all packets and manipulating them from central controls
    • This could potentially reduce redundancy and improve efficiency
  1. Key Message:
  • There are many types of packet processing devices on the network
  • Redundancy occurs as each device performs similar functions
  • Need to explore possibility of centralized packet management system

The diagram effectively highlights the complexity and redundancy in modern network architecture while suggesting a potential path toward more efficient packet processing through centralization.

This visualization emphasizes how current network infrastructure might benefit from consolidation of packet processing functions to reduce duplicated efforts and potentially lower costs.

Hub/Switch/Router

From ChatGPT with some prompting
The image appears to be an educational diagram explaining the basic functions and differences between three types of network devices: hubs, switches, and routers. Here’s what the image indicates about each device:

  • Hub: A hub is a simple networking device that broadcasts all incoming data packets to every connected device, regardless of the destination MAC address. It’s depicted as sending the same data to devices A, B, C, and D.
  • Switch: Unlike a hub, a switch is intelligent enough to filter and forward data packets based on their destination MAC addresses. This means it only sends the data to the specific device it is intended for, improving network efficiency and reducing collisions.
  • Router: A router operates at a higher level than switches and hubs. It routes data packets not just based on MAC addresses but also using IP addresses. It can connect multiple networks and manage the data traffic between them using protocols like BGP (Border Gateway Protocol).

The note at the bottom of the image states that the functions of these devices are not completely separated, and higher-level equipment includes the functions of the lower-level equipment. This means routers can perform the functions of switches, which in turn can perform the functions of hubs.

From Gemini with some prompting
The image is a diagram of a network consisting of hubs, switches, and routers. The functions of each device are as follows:

Hub: A hub is a central device that connects network devices. All devices connected to a hub can communicate with each other. When a hub receives a data frame, it transmits it to all ports.

Switch: A switch is similar to a hub, but it only transmits data to the device connected to each port. A switch uses MAC addresses to determine which port to transmit a data frame to.

Router: A router is a device that connects two or more networks. A router uses IP addresses to determine which network to transmit a data packet to.

In the image, each device is connected as follows:

  • Computers A, B, C, D: Each computer is connected to a hub or switch.
  • Hub: The hub is connected to a switch.
  • Switch: The switch is connected to a router.

The image also includes a description of the type of data that each device handles:

  • Hub: The hub transmits all data frames to all ports.
  • Switch: The switch uses MAC addresses to determine which port to transmit a data frame to.
  • Router: The router uses IP addresses to determine which network to transmit a data packet to.
