Filed:

Sep 23, 2003

Appl. No.:

10/668455

Inventors:

Ronald W. Szeto - Pleasanton CA, US
Philip Kwan - San Jose CA, US
Raymond Wai-Kit Kwong - Los Altos CA, US

Assignee:

Foundry Networks, Inc. - San Jose CA

International Classification:

H04L 29/06
G06F 21/00

US Classification:

726 13, 713154, 713162, 726 14

Abstract:

A system and method that provides for protection of a CPU of a router, by establishing a management port on a router. Hosts which are connected to a non-management ports of the router are denied access to management functions of a CPU of the router. The system and method can utilize an application specific integrated circuit, in conjunction with a CAM-ACL, which analyzes data packets received on the ports of router, and the ASIC operates to drop data packets which are directed to the CPU of the router. This system and method operates to filter data packets which may be generated in attempts to hack in to control functions of a network device, and the operation does not require that the CPU analyze all received data packets in connection with determining access to the control functions of the router.

Assignee:

Universal Display Corporation - Ewing NJ

International Classification:

H01J 1/62
C07C 13/66

US Classification:

313504, 585 26

Abstract:

Novel triphenylene compounds are provided. Specific examples include multi-aryl-substituted triphenylenes. A preferred group of compounds are triphenylenes that are substituted with a non-fused aryl group having one or more meta-substituents, where each meta-substituent is a non-fused aryl group optionally substituted with further substituents selected from the group consisting of non-fused aryl groups and alkyl groups. A further preferred group of compounds are triphenylenes that are substituted with a non-fused heteroaryl group having one or more meta-substituents, where each meta-substituent is a non-fused aryl or heteroaryl group optionally substituted with further substituents selected from the group consisting of non-fused aryl groups, non-fused heteroaryl groups, and alkyl groups. Some high triplet energy analogs are expected to work with deep blue phosphorescent dopants. The compounds may be useful in phosphorescent organic light emitting devices. Also provided is an organic electroluminescent device comprising an anode, a cathode, and an emissive layer between the anode and the cathode, the emissive layer comprising a phosphorescent material and a compound having a repeat unit, the repeat unit containing a triphenylene moiety.
