Intro to Guangdong Self-Study Exam course 13833 Switching and Routing Technologies (交换与路由技术)

Answer

13833 交换与路由技术 is a professional core course in the Guangdong Higher Education Self-Study Examination (广东高等教育自学考试), mainly for 计算机应用技术 (Computer Application Technology). It is a practical networking course focused on configuring and managing enterprise networks. ([Guangdong Exam Authority][1])

It is basically a CCNA-level networking course, but adapted for China’s self-study exam system. The official syllabus emphasizes:

network fundamentals
switch configuration
router configuration
security configuration
IPv6
Huawei network simulator practice

([Guangdong Exam Authority][1])

1. Where it sits in the CS knowledge map

Think of the stack:

Application
   |
HTTP / DNS / SSH
   |
TCP / UDP
   |
IP routing  <----- 13833 starts here
   |
Ethernet switching <----- 13833 focuses here
   |
Physical layer

Compared with another self-study course:

Course	Focus
02141 Computer Networks	theory: OSI, TCP/IP, protocols
13833 Switching and Routing Technologies	practical: configure switches/routers

([LZW Java][2])

For an engineer, 13833 is closer to:

Computer Networks
        +
CCNA
        +
Huawei H3C enterprise networking practice

2. Core topics

Part 1: Basic networking

You need:

IP address

Example:

192.168.1.0/24

means:

network:
192.168.1.0

hosts:
192.168.1.1 - 192.168.1.254

Subnetting:

/24
255.255.255.0


/26
255.255.255.192

This is frequently tested.

3. Switching (交换)

A switch works at Layer 2.

Example:

PC1
 |
 |
Switch
 |
 |
PC2

The switch learns MAC addresses:

MAC table:

AA:BB:CC -> port 1
DD:EE:FF -> port 2

VLAN

Very important.

Without VLAN:

        Switch

PC1 -------- PC2 -------- PC3

Everyone is in one broadcast domain.

With VLAN:

VLAN10

PC1
 |
Switch


VLAN20

PC2
 |
Switch

Logical separation.

Huawei command example:

system-view

vlan 10

interface GigabitEthernet 0/0/1

port link-type access

port default vlan 10

4. STP (Spanning Tree Protocol)

Problem:

Network loops:

        Switch A
       /        \
      /          \
 Switch B ------ Switch C

Ethernet originally has no TTL.

Broadcast storm:

packet
 ↓
A → B → C → A → ...

STP blocks one path:

        Switch A
       /
      /
 Switch B ------ Switch C
        blocked

Exam likes:

root bridge
port roles
blocking state

5. Routing (路由)

Router connects different networks:

192.168.1.0

     |
   Router

     |

192.168.2.0

Router table:

Destination        Next hop

192.168.2.0/24     eth0

Static routing

Manual:

ip route-static
192.168.2.0 255.255.255.0 10.0.0.2

Good for small networks.

Default routing

“Everything else goes here”

0.0.0.0/0
        |
     Internet

Dynamic routing

The router learns automatically.

RIP

Old protocol:

distance-vector

metric:
hop count

Maximum:

15 hops

OSPF

Important.

Used in enterprise networks.

Concept:

Router A
   |
 OSPF
   |
Router B

Features:

link state
shortest path
areas

Algorithm:

Dijkstra

6. Huawei simulator

The course specifically uses Huawei router/switch simulation. ([Guangdong Exam Authority][1])

Typical tool:

eNSP

Example lab:

PC1

 |
Switch

 |
Router

 |
Switch

 |
PC2

Configure:

VLAN
trunk
router interface
static route
OSPF

7. Difficulty for you

Given your background:

Java backend
Linux
cloud
Kubernetes
AWS/GCP
AI infrastructure

This course should be easy-medium.

The difficult part is not programming.

It is memorizing networking details:

MAC
ARP
VLAN
STP
IP subnet
routing table
OSPF
ACL
NAT
IPv6

Your advantage:

You already understand distributed systems.

Example:

Kubernetes:

Pod
 |
Service
 |
Network

Underneath:

IP routing
iptables
CNI
bridge
overlay network

This course gives the lower layer.

8. Suggested study path

I would do:

Week 1
TCP/IP basics
subnetting


Week 2
Ethernet
MAC
ARP
VLAN


Week 3
STP
trunk
link aggregation


Week 4
Static routing
RIP
OSPF


Week 5
ACL
NAT
IPv6


Week 6
Huawei eNSP labs
past papers

9. Relation to AI infrastructure

Actually this subject connects to modern AI clusters.

Example:

GPU cluster:

GPU Server
    |
Ethernet / InfiniBand
    |
Switch
    |
Router
    |
Storage

Large training clusters need:

topology design
bandwidth
congestion control
routing

The same concepts appear in:

NVIDIA networking
RDMA
RoCE
AI datacenter design

So this is not an outdated course.

It is the foundation layer below AI infrastructure.
