Broadcom's Trident 3 family incorporates the FleXGS architecture, allowing users to introduce new switching and instrumentation features via field-upgrade.
Broadcom Ltd has released the first members of its Trident 3 family of programmable switches for datacentre, enterprise and service provider networks transitioning to high density 10/25/100G Ethernet. According to company, the StrataXGS Trident 3 switch series is manufactured in 16nm and offers fully programmable line-rate switching, reconfigurable on-chip databases, load balancing and embedded instrumentation for network visibility.
The FleXGS architecture in Trident 3 is made up of programmable parsing, lookup and editing engines with associated reconfigurable databases. The engines are dimensioned and arrayed to maximise parallelism, performance, functional capacity and area/power efficiency, Broadcom noted.
The pipeline can be programmed to handle software-defined network virtualisation and service chaining protocols, including VXLAN, GPE, NSH, Geneve, MPLS, MPLS over GRE, MPLS over UDP, GUE, identifier locator addressing (ILA) and PPPoE, among others. The architecture also supports programmable telemetry, including insertion/processing of in-band telemetry headers (and associated packet metadata such as traffic identifiers and timestamps) as well as out-of-band network visibility (such as per-packet/per-flow attribute histograms and new ERSPAN like protocols). Programmability can be used in conjunction with Trident 3 native traffic engineering functions such as configurable ECMP and dynamic, state-based load balancing and multipathing.
The FleXGS allows users to introduce new switching and instrumentation features via field-upgrade.
Other features of the FleXGS programmable architecture include:
StrataXGS Trident 3 switch series features include:
Broadcom is now sampling the first two members of the StrataXGS Trident 3 family, the BCM56870 (3.2Tbps) and BCM56873 (2Tbps).
