- Description of Working Group:
-
- Due to dramatic increases in circuits speed the traditional system
- buses are limited in length (e.g., PCI is limited to 8") and cannot
- provide the traditional system-wide support. Therefore, the system-wide
- connectivity is provided by a high performance networks operating in
- very close quarters, having the generic name System Area Networks
- (SANs).
-
- Many vendors today use such SANs inside computer platforms to connect
- processors to IO devices, processors to memory, and processors to
- processors. Most existing SANs are proprietary, and don't interoperate
- with each other, not unsimilar to the early stages of LAN development.
-
- In order to be able to interconnect Massively Parallel Processing
- systems (MPPs) and to interconnect workstations into MPP-like clusters
- there is a need to unify the SANs and to provide means for
- interoperability among them.
-
- PktWay is designed to provide a uniform interface for a wide variety of
- SANs, such that the higher levels (such as IP) would be able to use
- SANs in a uniform manner. An IP driver for PktWay would be able to use
- PktWay between heterogeneous processors as if they were all on a single
- SAN.
-
- PktWay would be designed to provide interoperability among closely
- located heterogeneous processors at high speed. Pktway will sacrifice
- scalability and some generality for high performance. Hence, PktWay
- will supplement IP for high performance and for fine granularity of
- processors.
-
- 802.1, the link level control protocol is above LANs, such as the
- various Ethernets, FDDI, and Token Ring, at Level-2, and below IP, at
- Level-3.
-
- Similarly, PktWay will be above the various SANs (such as RACEway and
- Paragon) and below IP.
-
- PktWay will define separately:
-
- * End-to-End protocol (and packet format)
-
- * Router-to-Router protocol (and packet format)
-
- * Resource discovery and allocation
-
-
- The members of the PktWay Working Group will design, specify, document,
- propose, implement, and evaluate the above three protocols that define
- the PktWay operation.
-
- The members of the working group will also produce reference software
- for PktWay.
-
- Based on initial reactions it is expected that the working group will
- include members from academia, government, and industry, covering the
- software, hardware, and communication aspects of PktWay.
-
- INTELLECTUAL PROPERTY
-
- All the work that has been performed until now on PktWay is in the
- public domain. The PktWay Working Group will only handle public domain
- information. All the members of the PktWay Working Group will be
- notified that the working group cannot guard any trade secrets, nor
- limit the distribution of any proprietary information presented to it.
-
- Goals and Milestones:
-
