Defining Uplink Types
You define uplink types in the Sites & Networks page.
An uplink type is a name for similar functioning uplinks. On the SCC, uplink types can be used across multiple sites and path selection rules can be created using these names. The name must be unique at a site (but it can be same across different sites) so that the system can detect which path selection rule uses which uplinks. Because path selection rules are global on the SCC, you are restricted to 8 uplink types.
Uplink types are the building blocks for path selection. You select the path preference order using the uplink types created, and it is used in various sites. Riverbed recommends that you reuse the same uplink types at different sites in order to label uplinks based on the preference for path selection. For example, you can label uplink types as primary, secondary, and tertiary based on the path selection preference. The uplink type can be based on the type of interface or network resource, such as Verizon or global resource of uplink abstraction that is tied to a network.
Note: On the SteelHead, this field is called the Uplink Name, on the SCC it is the Uplink Type. Riverbed recommends using the same name for an uplink in all sites connecting to the same network.

Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore Link May 2026

Jacked piling, also known as hydraulic jacking, involves pushing precast or spun piles into the ground using static hydraulic force rather than dynamic impact. This method is particularly suitable for Singapore’s urban environment, where noise and vibration from traditional driven piles could damage adjacent structures.

: Jacking continues until practical refusal is achieved, at which point the pressure is released and reapplied without pause to verify the set. 2. Ground Condition Monitoring

: Specialist builders (e.g., G2 and G3 categories) must maintain rigs with minimum counterweights of 200 to 400 tonnes . Jacked piling, also known as hydraulic jacking, involves

To confirm the design assumptions, GeoSS Guidelines on Pile Load Testing recommend:

The Geotechnical Society of Singapore (GeoSS) has established a Guideline on Jacked Piles to standardize the installation of jacked foundation piles, a method favored in Singapore for its vibration-free and low-noise characteristics. : Allowable pile top settlements are typically limited

: Allowable pile top settlements are typically limited to 15mm at 1.5 times WL and 25mm at 2.0 times WL .

: Rigs should undergo a regular maintenance regime with daily, monthly, and yearly checklists to ensure they remain in safe working condition. Verification and Load Testing Machine Stability and Safety

) adjusted in steps to a value of .

: Jack-in machines are heavy and require a stable, reinforced working platform to prevent the rig from tilting or sinking during operation.

: In areas like the Jurong Formation or Bukit Timah Granite , varying rock profiles can lead to "short piles" if boulders or hard layers are encountered unexpectedly. 3. Machine Stability and Safety
