Comprehensive Solution of VxWorks network protocol stack system (1)

In the face of the ever-expanding network, with the combination of multiple protocols, I don't know if you know anything about the VxWorks network protocol stack. With the rapid growth of the Internet and the prevalence of WWW, TCP/IP has become the preferred network protocol for intranets and wide area networks. As more applications require protocol capabilities, IETF organizations are working to add new features to TCP/IP. Now WindRiver has released a real-time protocol stack to support these new features.

The VxWorks network protocol stack is a BSD4.4-compatible real-time TCP/IP protocol stack in VxWorks. It is upgraded from the BSD4.3-based protocol stack, with the addition of full route support and some new Internet features, the network performance of VxWorks is superior.

The VxWorks network protocol stack is a high-performance protocol stack suitable for high-performance network switching devices to low-cost network access devices, such as 10 M/M Ethernet switches, Wan access devices, and ATM switches. the software package is adjustable so that developers can apply it to an application system based on SNMP management from an IP routing device to a full TCP/IP. the VxWorks protocol stack provides the latest routing technology required for local switches or remote access routers. It can be used for gigabit Ethernet switches or DSL-access multiplexing.

The VxWorks Stack also supports multiple IP address multicast, CIDR, DHCP, DNS, SNTP, and other network protocols.

The routing engine of the VxWorks protocol stack uses an improved binary tree algorithm called PATRICIA. Even in a large route table, it can provide high-speed routing lookup performance, this routing engine can run faster IP packet transfer and provide API application interfaces) to add or delete route information. windRiver used the standard protocol package developed by Midnight to test all routing protocols.

The VxWorks network protocol stack has been carefully designed to greatly improve the performance of various applications. tested, the network throughput or CPU usage is 15% to higher than the previous version ~ 20% improvement. The optimization measures include canceling Data Copying on the TCP layer, using Hash tables, and improving the buffer management method.

VxWorks protocol stack fully integrated with MIB-II support, including the following MIB-II table: interface, IP, address resolution, ICMP, TCP, UDP and so on.
