In-Depth Information
•
Reliable message service
—A virtual-circuit service that provides reliable sequenced and
acknowledged delivery of messages between network nodes. A reliable message can be transmitted
in a maximum of four VIP packets.
•
Data stream service
—Supports the controlled flow of data between two processes. The data stream
service is an acknowledged virtual circuit service that supports the transmission of messages of
unlimited size.
Upper-Layer Protocols
As a distributed network, VINES uses the remote-procedure call (RPC) model for communication
between clients and servers. RPC is the foundation of distributed service environments. The NetRPC
protocol (Layers 5 and 6) provides a high-level programming language that allows access to remote
services in a manner transparent to both the user and the application.
At Layer 7, VINES offers file-service and print-service applications, as well as StreetTalk, which
provides a globally consistent name service for an entire internetwork.
VINES also provides an integrated applications development environment under several operating
systems, including DOS and UNIX. This development environment allows third parties to develop both
clients and services that run in the VINES environment.
Troubleshooting Banyan VINES
This section presents protocol-related troubleshooting information for connectivity problems related to
Banyan VINES. It describes specific VINES symptoms, the problems that are likely to cause each
symptom, and the solutions to those problems.
The following sections describe the most common errors experienced in Banyan VINES networks:
•
VINES: Clients Cannot Communicate with Servers over Router
•
VINES: Client Cannot Connect to Server over PSN
•
VINES: Client on Serverless Network Cannot Connect to Server over PSN
VINES: Clients Cannot Communicate with Servers over Router
Symptom:
Clients cannot connect to VINES servers over one or more routers. Clients might or might not
be able to connect to servers on their directly connected networks.
