For Immediate Release

TCP Extended Statistics is Ready-to-Use in CIAgent®

Knoxville, TN, September 15, 2010 - SNMP Research offers a ready-to-use implementation of RFC 4898 (TCP Extended Statistics MIB) as part of its next-generation MIB-II support in SNMP Agents for IPv4 and IPv6 networks. SNMP Research's MIB-II implementation for CIAgent® beginning in Release 17.2 (April 2010) includes RFCs 1213, 2863, 3418, 4001, 4022, 4113, 4292, 4293, and 4898.

Network managers who need to diagnose performance problems in the network and in applications that require TCP/IP communication use the TCP Extended Statistics MIB to identify bottlenecks that may be located in the sender, the receiver, or the network. If a bottleneck is found in the network, the TCP Extended Statistics MIB can provide specific information about its nature. The TCP Extended Statistics MIB contains some read-write objects that provide the manager with per-connection controls that can be used to work around a number of common problems that plague TCP over some paths. This feature is available today for Linux operating systems that incorporate web100 extensions ( and provide the web100 dynamically-loadable userland shared library ( SNMP Research's MIB-II source code can be licensed for use by developers of other platforms to use as a framework for implementing the TCP Extended Statistics MIB on operating systems other than Linux.

Network managers who need to monitor or log TCP/IP connections for problem diagnosis or security concerns use the TCP Extended Statistics MIB to generate SNMP Traps when a new connection is established (tcpEStatsEstablishNotification) and when an existing connection has recently closed (tcpEStatsCloseNotification). The payload of the Trap message is a MIB object called tcpEStatsConnectIndex that identifies the row in the TCP Connection Table associated with the TCP connection that was established or closed. A MIB object called tcpEStatsConnTableLatency controls how long after a connection has closed that its information remains in the TCP Connection Table. This feature of the TCP Extended Statistics MIB allows the network manager to reliably obtain information about a TCP connection that has already closed. All SNMP Research SNMP Agents (including CIAgent) for all supported platforms and operating systems can generate these Traps today.

CIAgent is a tool for monitoring the status of mission-critical network components, hardware/operating system components, and software applications. CIAgent provides an early warning system for both detecting problems and notifying operations personnel. Based on SNMP and Internet Engineering Task Force (IETF) documents, CIAgent provides a standards-based monitoring and control interface that can be accessed via a Web-based interface (DR-Web) or from a management application like EnterPol®, HP OpenView Network Node Manager, CA eHealth®, CA SPECTRUM®, IBM Tivoli® NetView®, and others.
