Press release: Vanguard router networks are becoming fault-tolerant.

Race Communications, an accredited distributor of Vanguard Managed Solutions, has started supplying Vanguard multiservice routers with the Open Networking System (ONS) version 6.3 operating system to Russia.

The new version of ONS 6.3 software extends the capabilities of Vanguard devices by various means to improve the security and performance of networks, including standard encryption using Triple DES/AES algorithms, support for the T.38 facsimile specification, and VRRP router redundancy tools.

"It is gratifying that Vanguard MS continues to improve both its routers and the software for them," said Rafael Shamiev, Head of the Race Communications Product Department. - In accordance with the requirements of the market, the main focus is on IP, voice transmission and information protection."

New Vanguard multiservice routers with ONS version 6.3. are available at Race Communications warehouse since September 15, 2003.

The VRRP protocol (Virtual Router Redundancy Protocol) is used to eliminate a single Point of failure in networks with a default gateway. VRRP allows multiple routers from the same LAN to access different WAN channels using a single virtual IP address. Various activation scenarios allow you to reserve the main router, distribute the load and maintain network integrity in case of channel failures. The VRRP protocol is supported in all Vanguard routers and is based on standards, which ensures compatibility with equipment from other manufacturers.

The T.38 standard allows fax documents to be transmitted over IP networks using H.323 gateways connected to fax machines. This ensures not only the transmission of facsimile documents in accordance with the Group 3 specification, but also compatibility with third-party H.323 software and hardware gateways is achieved. The exchange of facsimile documents with a speed of up to 14.4 kbit/s over data transmission networks, including the Internet, helps to reduce the costs of companies for telephone conversations.

Encryption using Triple DES/AES algorithms is initially implemented in routers of the Vanguard 342 model. Compared to other encryption algorithms implemented in Vanguard equipment (DES, Triple DES, IP Sec), AES provides improved protection of transmitted data. This algorithm allows you to set the key length to 128, 192 or 256 bits. Support for the AES standard makes Vanguard 342 compatible with a wide range of software and hardware information security tools. In subsequent ONS versions, data closure functions in accordance with Triple DES/AES will appear in other Vanguard routers.
