Bandwidth allocation rule examples

Example 1: Limiting bandwidth for the streaming servers  

The following bandwidth settings allocate a maximum aggregate bandwidth capacity of 100 Mbps, for all server-side streaming connections to share during daylight hours.

Rule properties:

1

Streaming

Use 
bucket 1

server traffic, time 
7:00am-7:00pm

Bucket properties:

1

100 
Mbits/sec

Disabled

--

Example 2: Limiting bandwidth for a specific server  

The following bandwidth settings allocate a maximum aggregate bandwidth capacity of 10 Mbps, for all Web traffic directed at the server with destination IP address 128.10.10.0 port 80.

Rule properties:

2

HTTP

Use bucket 2

to 128.10.10.0 80, 7:00am-
7:00pm

Bucket properties:

2

10 Mbits/sec

Disabled

--

Example 3: Limiting bandwidth for a specific interface  

The following bandwidth settings allocate a maximum aggregate bandwidth capacity of 100 Kbps, for all Web traffic received at appliance interface ns0.

3

HTTP

Use bucket 3

in, via ns0

Bucket properties:

3

100 kbytes/sec

Disabled

--

Example 4: Limiting bandwidth by protocol  

The following bandwidth rules provide

• A bandwidth pipe of 100 Mbps for all streaming protocol traffic
• Another bandwidth pipe of 100 Mbps to be shared by all other protocols

Rule properties:

1

Streaming

Use bucket 1

--

2

IP

Use bucket 2

--

Bucket properties:

1

100 Mbits/sec

Disabled

--

2

100 Mbits/sec

Disabled

Example 5: Limiting inbound and outbound connections  

The following bandwidth settings use dynamic bucket properties to limit clients to 64 Kbps (for NNTP connections, both inbound and outbound).

Note
In the following example, the IP address 172.30.200.60 represents the appliance and 119 represents the port number for NNTP traffic.

Rule properties:

1

TCP

Use bucket 1

from any to 172.30.200.60 
119

2

TCP

Use bucket 1

from 172.30.200.60 119 to 
any

Bucket properties:

1

64 
Kbits/sec

Disabled

 mask src-ip 0xffffffff 
dst-ip 0xffffffff

Example 6: Limiting client-side connections  

The following bandwidth allocation settings use dynamic bucket properties to limit each client to 50 Kbps (for NNTP connections to clients only).

Note
In the following example, the IP address 172.30.200.60 represents the appliance and 119 represents the port number for NNTP traffic.

Rule properties:

1

TCP

Use bucket 1

from 172.30.200.60 119 to 
any

Bucket properties:

1

50 
Kbits/sec

Disabled

mask dst-ip 0xffffffff 
dst-port 0xffff
