Solaris 10 What's New

New Architecture for Network Stacks

This new architecture is of key importance in the Solaris 10 system. This feature is new in the Solaris Express 10/03 release.

The networking stack for TCP connections has been rearchitected to deliver extremely high performance while improving the scalability. This innovation enables Solaris networking to vertically partition the workload by using an IP classifier-based lockless design. This design reduces the overheads of synchronization and reduces cross-communication between CPUs. The improvements are visible across all networking workloads and are transparent to the users.
