Advanced Industrial Networking Features

Standards based layer-2 functionality is critical for providing multi-vendor interoperability and supporting various traffic types with different characteristics. For example, voice applications are less tolerant of delay and jitter in the network than email and network access. Therefore, the ability to customize each traffic stream based on its characteristics is important to successfully deploy a shared layer 2 backbone.

Rapid Spanning Tree Protocol (RSTP)

The JumboSwitch® supports all Spanning Tree Protocols including: Spanning Tree Protocol (IEEE 802.1d), Rapid Spanning Tree Protocol (IEEE802.1w) and Multiple Spanning Tree Protocol (IEEE802.1s). These protocols prevent Ethernet broadcast storms and offer fast recovery of mesh topology networks.

Service Priority (IEEE 802.1p)

During heavy usage switches can introduce latency due to their first come, first serve nature. The JumboSwitch® supports IEEE 802.1p which enables it to support up to eight levels of priorities for different types of traffic. A voice-over-IP packet is supported, for example, by moving it to the front of the queue to prevent noticeable latency and minimize jitter.

VLAN (IEEE 802.1Q)

Virtual Local Area Networks (VLAN) logically segregate shared physical networks. This type of segregation provides added security as only members of a VLAN are allowed to communicate. Ethernet ports on the JumboSwitch® can be configured to support IEEE 802.1Q tagged Ethernet frames, VLAN Trunks, or hybrid (a member port for multiple VLANs) to maximize network design flexibility.

Rate Limiting

The JumboSwitch® supports rate limiting on incoming traffic on a per-port or per-card basis. This feature prevents unnecessary traffic congestion and enables more efficient use of the bandwidth.
